Brain-Derived Neurotrophic Factor
A member of the nerve growth factor family of trophic factors. In the brain BDNF has a trophic action on retinal, cholinergic, and dopaminergic neurons, and in the peripheral nervous system it acts on both motor and sensory neurons. (From Kendrew, The Encyclopedia of Molecular Biology, 1994)
Prader-Willi Syndrome
An autosomal dominant disorder caused by deletion of the proximal long arm of the paternal chromosome 15 (15q11-q13) or by inheritance of both of the pair of chromosomes 15 from the mother (UNIPARENTAL DISOMY) which are imprinted (GENETIC IMPRINTING) and hence silenced. Clinical manifestations include MENTAL RETARDATION; MUSCULAR HYPOTONIA; HYPERPHAGIA; OBESITY; short stature; HYPOGONADISM; STRABISMUS; and HYPERSOMNOLENCE. (Menkes, Textbook of Child Neurology, 5th ed, p229)
Receptor, trkB

Luteal Phase
The period in the MENSTRUAL CYCLE that follows OVULATION, characterized by the development of CORPUS LUTEUM, increase in PROGESTERONE production by the OVARY and secretion by the glandular epithelium of the ENDOMETRIUM. The luteal phase begins with ovulation and ends with the onset of MENSTRUATION.
Menstrual Cycle
The period from onset of one menstrual bleeding (MENSTRUATION) to the next in an ovulating woman or female primate. The menstrual cycle is regulated by endocrine interactions of the HYPOTHALAMUS; the PITUITARY GLAND; the ovaries; and the genital tract. The menstrual cycle is divided by OVULATION into two phases. Based on the endocrine status of the OVARY, there is a FOLLICULAR PHASE and a LUTEAL PHASE. Based on the response in the ENDOMETRIUM, the menstrual cycle is divided into a proliferative and a secretory phase.

Expression of the naturally occurring truncated trkB neurotrophin receptor induces outgrowth of filopodia and processes in neuroblastoma cells. (1/3019)

We have investigated the effects of the truncated trkB receptor isoform T1 (trkB.T1) by transient transfection into mouse N2a neuroblastoma cells. We observed that expression of trkB.T1 leads to a striking change in cell morphology characterized by outgrowth of filopodia and processes. A similar morphological response was also observed in SH-SY5Y human neuroblastoma cells and NIH3T3 fibroblasts transfected with trkB.T1. N2a cells lack endogenous expression of trkB isoforms, but express barely detectable amounts of its ligands, brain-derived neurotrophic factor (BDNF) and neurotrophin-4 (NT-4). The morphological change was ligand-independent, since addition of exogenous BDNF or NT-4 or blockade of endogenous trkB ligands did not influence this response. Filopodia and process outgrowth was significantly suppressed when full-length trkB.TK+ was cotransfected together with trkB.T1 and this inhibitory effect was blocked by tyrosine kinase inhibitor K252a. Transfection of trkB.T1 deletion mutants showed that the morphological response is dependent on the extracellular, but not the intracellular domain of the receptor. Our results suggest a novel ligand-independent role for truncated trkB in the regulation of cellular morphology.  (+info)

Activated macrophages and microglia induce dopaminergic sprouting in the injured striatum and express brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor. (2/3019)

Nigrostriatal dopaminergic neurons undergo sprouting around the margins of a striatal wound. The mechanism of this periwound sprouting has been unclear. In this study, we have examined the role played by the macrophage and microglial response that follows striatal injury. Macrophages and activated microglia quickly accumulate after injury and reach their greatest numbers in the first week. Subsequently, the number of both cell types declines rapidly in the first month and thereafter more slowly. Macrophage numbers eventually cease to decline, and a sizable group of these cells remains at the wound site and forms a long-term, highly activated resident population. This population of macrophages expresses increasing amounts of glial cell line-derived neurotrophic factor mRNA with time. Brain-derived neurotrophic factor mRNA is also expressed in and around the wound site. Production of this factor is by both activated microglia and, to a lesser extent, macrophages. The production of these potent dopaminergic neurotrophic factors occurs in a similar spatial distribution to sprouting dopaminergic fibers. Moreover, dopamine transporter-positive dopaminergic neurites can be seen growing toward and embracing hemosiderin-filled wound macrophages. The dopaminergic sprouting that accompanies striatal injury thus appears to result from neurotrophic factor secretion by activated macrophages and microglia at the wound site.  (+info)

BDNF mediates the effects of testosterone on the survival of new neurons in an adult brain. (3/3019)

New neurons are incorporated into the high vocal center (HVC), a nucleus of the adult canary (Serinus canaria) brain that plays a critical role in the acquisition and production of learned song. Recruitment of new neurons in the HVC is seasonally regulated and depends upon testosterone levels. We show here that brain-derived neurotrophic factor (BDNF) is present in the HVC of adult males but is not detectable in that of females, though the HVC of both sexes has BDNF receptors (TrkB). Testosterone treatment increases the levels of BDNF protein in the female HVC, and BDNF infused into the HVC of adult females triples the number of new neurons. Infusion of a neutralizing antibody to BDNF blocks the testosterone-induced increase in new neurons. Our results demonstrate that BDNF is involved in the regulation of neuronal replacement in the adult canary brain and suggest that the effects of testosterone are mediated through BDNF.  (+info)

Activated human T cells, B cells, and monocytes produce brain-derived neurotrophic factor in vitro and in inflammatory brain lesions: a neuroprotective role of inflammation? (4/3019)

Brain-derived neurotrophic factor (BDNF) has potent effects on neuronal survival and plasticity during development and after injury. In the nervous system, neurons are considered the major cellular source of BDNF. We demonstrate here that in addition, activated human T cells, B cells, and monocytes secrete bioactive BDNF in vitro. Notably, in T helper (Th)1- and Th2-type CD4(+) T cell lines specific for myelin autoantigens such as myelin basic protein or myelin oligodendrocyte glycoprotein, BDNF production is increased upon antigen stimulation. The BDNF secreted by immune cells is bioactive, as it supports neuronal survival in vitro. Using anti-BDNF monoclonal antibody and polyclonal antiserum, BDNF immunoreactivity is demonstrable in inflammatory infiltrates in the brain of patients with acute disseminated encephalitis and multiple sclerosis. The results raise the possibility that in the nervous system, inflammatory infiltrates have a neuroprotective effect, which may limit the success of nonselective immunotherapies.  (+info)

Growth factor-mediated Fyn signaling regulates alpha-amino-3- hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptor expression in rodent neocortical neurons. (5/3019)

Src-family protein tyrosine kinases (PTKs) transduce signals to regulate neuronal development and synaptic plasticity. However, the nature of their activators and molecular mechanisms underlying these neural processes are unknown. Here, we show that brain-derived neurotrophic factor (BDNF) and platelet-derived growth factor enhance expression of alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA)-type glutamate receptor 1 and 2/3 proteins in rodent neocortical neurons via the Src-family PTK(s). The increase in AMPA receptor levels was blocked in cultured neocortical neurons by addition of a Src-family-selective PTK inhibitor. Accordingly, neocortical cultures from Fyn-knockout mice failed to respond to BDNF whereas those from wild-type mice responded. Moreover, the neocortex of young Fyn mutants exhibited a significant in vivo reduction in these AMPA receptor proteins but not in their mRNA levels. In vitro kinase assay revealed that BDNF can indeed activate the Fyn kinase: It enhanced tyrosine phosphorylation of Fyn as well as that of enolase supplemented exogenously. All of these results suggest that the Src-family kinase Fyn, activated by the growth factors, plays a crucial role in modulating AMPA receptor expression during brain development.  (+info)

Differential sorting of nerve growth factor and brain-derived neurotrophic factor in hippocampal neurons. (6/3019)

Nerve growth factor (NGF) is released through the constitutive secretory pathway from cells in peripheral tissues and nerves where it can act as a target-derived survival factor. In contrast, brain-derived neurotrophic factor (BDNF) appears to be processed in the regulated secretory pathway of brain neurons and secreted in an activity-dependent manner to play a role in synaptic plasticity. To determine whether sorting differences are intrinsic to the neurotrophins or reflect differences between cell types, we compared NGF and BDNF processing in cultured hippocampal neurons using a Vaccinia virus expression system. Three independent criteria (retention or release from cells after pulse-chase labeling, depolarization-dependent release, and immunocytochemical localization) suggest that the bulk of newly synthesized NGF is sorted into the constitutive pathway, whereas BDNF is primarily sorted into the regulated secretory pathway. Similar results occurred with AtT 20 cells, including those transfected with cDNAs encoding neurotrophin precursor-green fluorescent protein fusions. The NGF precursor, but not the BDNF precursor, is efficiently cleaved by the endoprotease furin in the trans-Golgi network (TGN). Blocking furin activity in AtT 20 cells with alpha1-PDX as well as increasing the expression of NGF precursor partially directed NGF into the regulated secretory pathway. Therefore, neurotrophins can be sorted into either the constitutive or regulated secretory pathways, and sorting may be regulated by the efficiency of furin cleavage in the TGN. This mechanism may explain how neuron-generated neurotrophins can act both as survival factors and as neuropeptides.  (+info)

Brain-derived neurotrophic factor prevents low-frequency inputs from inducing long-term depression in the developing visual cortex. (7/3019)

Brain-derived neurotrophic factor (BDNF) is reported to enhance synaptic transmission and to play a role in long-term potentiation in hippocampus and neocortex. If so, a shortage or blockade of BDNF might lead to another form of synaptic plasticity, long-term depression (LTD). To test this possibility and to elucidate mechanisms if it is the case, EPSCs evoked by test stimulation of layer IV were recorded from layer II/III neurons in visual cortical slices of young rats in the whole-cell voltage-clamp mode. LTD was induced by low-frequency stimulation (LFS) at 1 Hz for 10-15 min if each pulse of the LFS was paired with depolarization of neurons to -30 mV but was not induced if their membrane potentials were kept at -70 mV. Such an LTD was blocked by exogenously applied BDNF, probably through presynaptic mechanisms. Suppression of endogenous BDNF activity by the anti-BDNF antibody or an inhibitor for BDNF receptors made otherwise ineffective stimuli (LFS without postsynaptic depolarization) effective for LTD induction, suggesting that endogenous BDNF may prevent low-frequency inputs from inducing LTD in the developing visual cortex.  (+info)

BDNF is a target-derived survival factor for arterial baroreceptor and chemoafferent primary sensory neurons. (8/3019)

Brain-derived neurotrophic factor (BDNF) supports survival of 50% of visceral afferent neurons in the nodose/petrosal sensory ganglion complex (NPG; Ernfors et al., 1994a; Jones et al., 1994; Conover et al., 1995; Liu et al., 1995; Erickson et al., 1996), including arterial chemoafferents that innervate the carotid body and are required for development of normal breathing (Erickson et al., 1996). However, the relationship between BDNF dependence of visceral afferents and the location and timing of BDNF expression in visceral tissues is unknown. The present study demonstrates that BDNF mRNA and protein are transiently expressed in NPG targets in the fetal cardiac outflow tract, including baroreceptor regions in the aortic arch, carotid sinus, and right subclavian artery, as well as in the carotid body. The period of BDNF expression corresponds to the onset of sensory innervation and to the time at which fetal NPG neurons are BDNF-dependent in vitro. Moreover, baroreceptor innervation is absent in newborn mice lacking BDNF. In addition to vascular targets, vascular afferents themselves express high levels of BDNF, both during and after the time they are BDNF-dependent. However, endogenous BDNF supports survival of fetal NPG neurons in vitro only under depolarizing conditions. Together, these data indicate two roles for BDNF during vascular afferent pathway development; initially, as a target-derived survival factor, and subsequently, as a signaling molecule produced by the afferents themselves. Furthermore, the fact that BDNF is required for survival of functionally distinct populations of vascular afferents demonstrates that trophic requirements of NPG neurons are not modality-specific but may instead be associated with innervation of particular organ systems.  (+info)

Experimental evidence in mice indicates that environmental conditions affect females and males differently. However, in a recent study analyzing the heterozygous mutation of brain-derived neurotrophic factor (BDNF), both sexes presented a similar emotional phenotype, which became obvious only under impoverished, but not in enriched conditions suggesting an enrichment-induced rescue. To investigate the basis of this behavioral rescue effect, we analyzed neurochemical changes (BDNF expression, serotonergic changes, and corticosterone) in the hippocampus, frontal cortex and hypothalamus of animals housed under respective conditions. In male mice, enrichment induced an increase of BDNF expression in the hippocampus of both BDNF heterozygous (BDNF(+/-)) and wild-types. Notably, in enriched-reared BDNF(+/-) mice BDNF mRNA and protein increased to levels comparable to those of wild-types in impoverished environment. In the frontal cortex of males, only wild-types presented an enrichment-induced increase of

Exercise is recognized as a promising approach to counteract aging-associated declines in cognitive functions. However, the exact molecular pathways involved remain unclear. Aerobic training interventions and improvements in peak oxygen uptake (VO2peak) have been associated with increases in the peripheral concentration of brain-derived neurotrophic factor (BDNF) and better cognitive performances. However, other training interventions such as resistance training and gross motor skills programs were also linked with improvements in cognitive functions. Thus far, few studies have compared different types of physical exercise training protocols and their impact on BDNF concentrations, especially in participants over 60 years old. The main objective of this study was to compare the effects of three exercise protocols on plasma BDNF concentrations at rest in healthy older adults. Thirty-four older adults were randomized into three interventions: (1) lower body strength and aerobic training (LBS-A), (2) upper

Background: Brain-derived neurotrophic factor (BDNF) mutant mice show hyperphagia and hyperleptinemia. Animal and cell-culture experiments suggest multiple interrelations between BDNF and the serotonin (5-HT) system. We studied serum BDNF in patients with anorexia nervosa and its associations with peripheral indicators of the 5-HT system. To control for secondary effects of acute malnutrition, we assessed acutely underweight patients with anorexia nervosa (acAN) in comparison to long-term weight-recovered patients with the disorder (recAN) and healthy controls.. Methods: We determined serum BDNF, platelet 5-HT content and platelet 5-HT uptake in 33 patients in the acAN group, 20 patients in the recAN group and 33 controls. Plasma leptin served as an indicator of malnutrition.. Results: Patients in the acAN group were aged 14-29 years and had a mean body mass index (BMI) of 14.9 (standard deviation [SD] 1.4) kg/m2.

Serum Levels of Brain-Derived Neurotrophic Factor at 4 Weeks and Respo by R. Yoshimura, T. Kishi et al.Serum Levels of Brain-Derived Neurotrophic Factor at 4 Weeks and Respo by R. Yoshimura, T. Kishi et al.
Objective It is important to predict a response to an antidepressant in early time after starting the antidepressant. We previously reported that serum brain-derived neurotrophic factor (BDNF) levels in responders to treatment with antidepressants were increased, whereas, those in nonresponders were not. Therefore, we hypothesized that the changes in serum levels of BDNF from baseline (TO) to 4 weeks (T4) after treatment with selective serotonin reuptake inhibitors (SSRIs) predict the response to the treatment at 8 weeks (T8) in depressed patients. To confirm the hypothesis, we measured serum BDNF at TO, T4, and T8 during the treatment with SSRIs (paroxetine, sertraline, and fluvoxamine). Methods One hundred fifty patients (M/F; 51/99, age; 50.4 +/- 15.1 years) met major depressive disorder (MDD) using by DSM-IV-TR enrolled in the present study. We measured serum BDNF concentrations at TO, T4, and T8 in patients with MDD treated with SSRIs. Results The changes in serum BDNF, age, sex, dose of SSRIs, and

BDNF and VEGF were analyzed as continuous variables. VEGF values were log-transformed to normalize the skewed distribution of VEGF. We used Cox-proportional hazards models to relate baseline serum BDNF and logVEGF levels (separately) to risk of incident stroke/TIA in Study Sample 1. We first examined the linear effect of a 1-SD unit increase/decrease in BDNF and logVEGF on risk of stroke/TIA. We also explored threshold effects comparing the risk across quartiles of BDNF and VEGF. We observed a threshold effect with BDNF only. Therefore, we ran threshold models for BDNF using the lowest quartile, Q1, as the reference and also assessed a threshold model comparing risk for persons in Q1 with persons in Q2 to Q4. We performed a similar set of analyses on a Study Sample 1b with stroke alone as the outcome. Using multivariable linear and logistic regression models, we examined the cross-sectional associations between BDNF and logVEGF and markers of brain aging (WMHV, and VR-d and Trails B-A ...

Coffee Modulates the Function of Brain-Derived Neurotrophic Factor (BDNF) in Human Neuroblastoma SH-SY5Y CellsCoffee Modulates the Function of Brain-Derived Neurotrophic Factor (BDNF) in Human Neuroblastoma SH-SY5Y Cells
Recent epidemiological studies showed that daily coffee consumption is associated with a lower risk for several neurological disorders such as Alzheimers disease and Parkinsons disease; however, the molecular mechanisms responsible for the protective effect of coffee against neurological disorders have not been elucidated. As brain-derived neurotrophic factor (BDNF) promotes neuronal survival and protects against neuronal damage, we investigated the effects of coffee on BDNF signaling using human neuroblastoma SH-SY5Y cells. We found that brewed coffee exerted an inhibitory effect on the autophosphorylation of tropomyosin receptor kinase B (TrkB), a BDNF receptor. Additionally, coffee reduced the phosphorylation of Akt in BDNF-treated SH-SY5Y cells. Treatment with coffee did not affect the TrkB receptor on the cell surface. The major constituents of coffee, such as caffeine, caffeic acid, chlorogenic acid, and trigonelline had no effect on TrkB phosphorylation induced by BDNF. In addition, coffee

Background Following voxel-based morphometry (VBM), brain-derived neurotrophic factor (BDNF) Val66Met polymorphism (rs6265) has been shown to affect human brain morphology in Caucasians. However, little is known about the specific role of the Met/Met genotype on brain structure. Moreover, the relationship between BDNF Val66Met polymorphism and Chinese brain morphology has not been studied. Methodology/Principal Findings The present study investigated brain structural differences among three genotypes of BDNF (rs6265) for the first time in healthy young Chinese adults via cortical thickness analysis and VBM. Brain differences in Met carriers using another grouping method (combining Val/Met and Met/Met genotypes into a group of Met carriers as in most previous studies) were also investigated using VBM. Dual-approach analysis revealed less gray matter (GM) in the frontal, temporal, cingulate and insular cortices in the Met/Met group compared with the Val/Val group (corrected, P|0.05).

Y1 - 1998/7/15. N2 - 1. Molecular mechanisms underlying maturation of the central respiratory rhythm are largely unknown. Previously, we found that brain-derived neurotrophic factor (BDNF) is required for expression of normal breathing behaviour in newborn mice, raising the possibility that maturation of central respiratory output is dependent on BDNF. 2. Respiratory activity was recorded in vitro from cervical ventral roots (C1 or C4) using the isolated brainstem-spinal cord preparation from postnatal day (P) 0.5-2.0 and P4.5 wild-type mice and mice lacking functional bdnf alleles. 3. Loss of one or both bdnf alleles resulted in an approximately 50% depression of central respiratory frequency compared with wild-type controls. In addition, respiratory cycle length variability was 214% higher in bdnf null ...

A Val66Met single-nucleotide polymorphism (SNP) in the brain-derived neurotrophic factor (BDNF) gene impairs activity-dependent BDNF release in cultured hippocampal neurons and predicts impaired memory and exaggerated basal hippocampal activity in healthy humans. Several clinical genetic association studies along with multi-modal evidence for hippocampal dysfunction in schizophrenia indirectly suggest a relationship between schizophrenia and genetically determined BDNF function in the hippocampus. To directly test this hypothesized relationship, we studied 47 medication-free patients with schizophrenia or schizoaffective disorder and 74 healthy comparison individuals with genotyping for the Val66Met SNP and [15O]H2O positron emission tomography (PET) to measure resting and working memory-related hippocampal regional cerebral blood flow (rCBF). In patients, harboring a Met allele was associated with significantly less hippocampal rCBF. This finding was opposite to the genotype effect seen in healthy

Regulation of local translation at the synapse by BDNFRegulation of local translation at the synapse by BDNF
The neurotrophin brain-derived neurotrophic factor (BDNF) plays a key role in synaptic plasticity, in part due to changes in local protein synthesis. Activation of TrkB (tropomyosin-related kinase B) receptors for BDNF triggers several parallel signaling pathways, including the Ras/ERK, the phosphatidylinositol 3-kinase (PI3-K) and the phospholipase C-Îł pathways. Recent studies have elucidated some of the signaling mechanisms that contribute to the regulation of translation activity by BDNF, through modulation of initiation and elongation phases, but the resulting changes in the proteome are not yet fully characterized. The proteins synthesized in response to activation of TrkB receptors by BDNF depend on the mRNAs that are available locally, after delivery and transport along dendrites. Recent studies have shown that BDNF may also play a regulatory role at this level. Furthermore, BDNF regulates transcription activity, thereby affecting the array of mRNAs available to be transported along dendrites.

The neurotrophin brain-derived neurotrophic factor (BDNF) can induce long-lasting strengthening of synapses in vivo and this effect is dependent on transcription. However, the mechanism of signaling to the nucleus is not well understood. Here we describe a microfluidic culture device to investigate dendrite-to-nucleus signaling. Using these microfluidic devices, we demonstrate that BDNF can act directly on dendrites to elicit an anterograde signal that induces transcription of the immediate early genes, Arc and c-Fos. Induction of Arc is dependent on dendrite- and cell body-derived calcium, whereas ...

Brain-derived neurotrophic factor (BDNF) is a protein that is important in nervous system development and function. BDNF also appears to function downstream of the leptin-melanocortin signaling pathway to control appetite. In both animals and humans, diminished BDNF function is associated with hyperphagia, obesity, and neurocognitive deficits. We propose to study BDNF in two hyperphagic disorders: Prader-Willi syndrome and MC4R function-altering mutations. We hypothesize that patients with PWS may have increased BDNF during infancy, followed by a decline in BDNF that precedes the onset of hyperphagia and persists after the onset of obesity. We hypothesize that patients with MC4R mutations will have decreased BDNF, the severity of which will be associated with the degree of MC4R functional loss caused by the specific mutation(s) in each individual. To test these hypotheses, we wish to conduct cross-sectional studies to evaluate serum BDNF concentrations, metabolism, body composition, and ...

Context: Brain-derived neurotrophic factor (BDNF) is a pleiotropic peptide also involved in maintaining endothelial integrity. It is unknown if circulating BDNF levels are associated with risk of cardiovascular disease (CVD).. Objective: To investigate the association of circulating BDNF with CVD risk Design, Setting and Participants: First, we prospectively investigated the association of circulating BDNF levels with cardiovascular events and mortality in the 3,687 participants (mean age 65 years, 2,068 women) from the Framingham Heart Study (FHS). Next, we evaluated the association of a common nonsynonymous SNP in the BDNF gene (rs6265) with circulating BDNF concentrations in FHS. Finally, we performed a Mendelian randomization experiment in the CARDIoGRAM consortium (,22,000 coronary artery disease [CAD] cases, ,60,000 controls) to investigate whether the same SNP was associated with CAD risk in CARDioGRAM and if so, whether the direction and effect size differed from that predicted based on ...

Author(s): Bamji, Shernaz X; Rico, Beatriz; Kimes, Nikole; Reichardt, Louis F | Abstract: Neurons of the vertebrate central nervous system have the capacity to modify synapse number, morphology, and efficacy in response to activity. Some of these functions can be attributed to activity-induced synthesis and secretion of the neurotrophin brain-derived neurotrophic factor (BDNF); however, the molecular mechanisms by which BDNF mediates these events are still not well understood. Using time-lapse confocal analysis, we show that BDNF mobilizes synaptic vesicles at existing synapses, resulting in small clusters of synaptic vesicles splitting away from synaptic sites. We demonstrate that BDNFs ability to mobilize synaptic vesicle clusters depends on the dissociation of cadherin-beta-catenin adhesion complexes that occurs after tyrosine phosphorylation of beta-catenin. Artificially maintaining cadherin-beta-catenin complexes in the presence of BDNF abolishes the BDNF-mediated enhancement of synaptic vesicle

The levels of brain-derived neurotrophic factor (BDNF) are significantly decreased in patients with schizophrenia and correlate with impairments in cognitive function. However, no study has investigated the relationship between the serum BDNF levels and decision-making. We compared patients with schizophrenia to healthy controls with respect to their decision-making ability and serum BDNF levels. Eighty-six chronic schizophrenia patients and 51 healthy controls participated in this study. We controlled for gender, age, and estimated intelligence quotient (IQ), and we investigated the differences in decision-making performance on the Iowa Gambling Task (IGT) between the schizophrenia patient and control groups. We also compared the IGT scores, the serum BDNF levels, and the clinical symptoms between the groups. The IGT scores of the schizophrenia patients were lower than those of the controls. A negative correlation was detected between the mean net scores on the trials in the final two blocks and the

Figure 4. Hippocampus and Perirhinal cortex in Human Brain (Figure Source). Some studies measured serum BDNF levels instead of specifically measuring brain BDNF concentration.[21][31][32][13] Serum BDNF is measured instead of brain levels because it can be measured without sacrificing the animal and is also acceptable for human studies. Acute changes in serum BDNF levels are thought to directly reflect changes in brain BDNF concentration[21][24]. There are several reasons for this: rat studies show correlations between serum and brain BDNF levels,[21] BDNF easily travels in both directions across the blood-brain barrier,[21][24] and both serum and brain BDNF levels are significantly reduced in AD.[24] There is conflicting evidence concerning exercise and its impact on serum BDNF.[24] Acute bouts of exercise have been found to increase serum BDNF levels,[21][24] but several studies have concluded that regular (chronic) exercise may lead to decreased serum BDNF levels compared to sedentary ...

Degeneration of neurons, such as the inner ear spiral ganglion neurons (SGN), may be decelerated or even stopped by neurotrophic factor treatment, such as brain-derived neurotrophic factor (BDNF), as well as electrical stimulation (ES). In a clinical setting, drug treatment of the SGN could start directly during implantation of a cochlear implant, whereas electrical stimulation begins days to weeks later. The present study was conducted to determine the effects of consecutive BDNF and ES treatments on SGN density and electrical responsiveness. An electrode drug delivery device was implanted in guinea pigs 3 weeks after deafening and five experimental groups were established: two groups received intracochlear infusion of artificial perilymph (AP) or BDNF; two groups were treated with AP respectively BDNF in addition to ES (AP + ES, BDNF + ES); and one group received BDNF from the day of implantation until day 34 followed by ES (BDNF ⇹ ES).

Environmental enrichment (EE) refers to the provision of a complex and stimulating housing condition which improves well-being, behaviour and brain function of laboratory animals. The mechanisms behind these beneficial effects of EE are only partially understood. In the current report, we describe a link between EE and neuropeptide Y (NPY), based on findings from NPY knockout (KO) mice exposed to EE. Relative to EE-housed wildtype (WT) animals, NPY KO mice displayed altered behaviour as well as molecular and morphological changes in amygdala and hippocampus. Exposure of WT mice to EE reduced anxiety and decreased central glucocorticoid receptor expression, effects which were absent in NPY KO mice. In addition, NPY deletion altered the preference of EE items, and EE-housed NPY KO mice responded to stress with exaggerated hyperthermia, displayed impaired spatial memory, had higher hippocampal brain-derived neurotrophic factor mRNA levels and altered hippocampal synaptic plasticity, effects which were not

Perhaps no other brain nutrient is receiving as much attention lately as DHA, especially after it was found to be a great way to increase BDNF. Scientists have been aggressively studying this critical brain fat for the past several decades for at least three reasons.. First, more than two-thirds of the dry weight of the human brain is fat, and one-quarter of that fat is DHA. From a structural point of view, DHA is an important building block for the membranes that surround healthy brain cells. These membranes include the areas where one brain cell connects to another, the synapses. This means that DHA is involved in the transmission of information from one neuron to the next and thus is fundamental for efficient brain function.. Second, DHA is one of natures important regulators of inflammation. Inflammation is responsible for a large number of brain maladies, including Alzheimers, Parkinsons, attention deficit hyperactivity disorder (ADHD), and multiple sclerosis. DHA naturally reduces the ...

Purpose : The concept that the brain-derived neurotrophic factor (BDNF) is a major trophic factor for retinal neurons is well-established. However, the cellular and molecular mechanisms governing BNDF production and its neuroprotective effect remain largely unknown. To determine the role of BDNF in neuroprotection in diabetic retinopathy (DR) and age-related macular degeneration (AMD), we investigated the mechanism of BDNF production/secretion by MĂŒller cells (MCs) and of BDNF-mediated MC viability under diabetic and hypoxic conditions using both in vivo and in vitro models. Methods : BDNF production and expression were quantified with immunoblotting and ELISA analysis using a rat MC line (rMC1) and condtional gene knockout (KO) mice. MC viability was measured by live cell quantification. MG and neuronal density in mice was analyzed with immunohistochemistry and retinal morphology was examined with light microscopy. Results : In high glucose media, MC secreted a high level of BDNF which was ...

Derics MindBlog: How exercise enhances brain renewal and growth.Derics MindBlog: How exercise enhances brain renewal and growth.
Exercise induces beneficial responses in the brain, which is accompanied by an increase in BDNF, a trophic factor associated with cognitive improvement and the alleviation of depression and anxiety. However, the exact mechanisms whereby physical exercise produces an induction in brain Bdnf gene expression are not well understood. While pharmacological doses of HDAC inhibitors exert positive effects on Bdnf gene transcription, the inhibitors represent small molecules that do not occur in vivo. Here, we report that an endogenous molecule released after exercise is capable of inducing key promoters of the Mus musculus Bdnf gene. The metabolite ÎČ-hydroxybutyrate, which increases after prolonged exercise, induces the activities of Bdnf promoters, particularly promoter I, which is activity-dependent. We have discovered that the action of ÎČ-hydroxybutyrate is specifically upon HDAC2 and HDAC3, which act upon selective Bdnf promoters. Moreover, the effects upon hippocampal Bdnf expression were ...

Early life environments interact with genotype to determine stable phenotypic outcomes. Here we examined the influence of a variant in the brain-derived neurotropic factor (BDNF) gene (Val66Met), which underlies synaptic plasticity throughout the central nervous system, on the degree to which antenatal maternal anxiety associated with neonatal DNA methylation. We also examined the association between neonatal DNA methylation and brain substructure volume, as a function of BDNF genotype. Infant, but not maternal, BDNF genotype dramatically influences the association of antenatal anxiety on the epigenome at birth as well as that between the epigenome and neonatal brain structure. There was a greater impact of antenatal maternal anxiety on the DNA methylation of infants with the methionine (Met)/Met compared to both Met/valine (Val) and Val/Val genotypes. There were significantly more cytosine-phosphate-guanine sites where methylation levels covaried with right amygdala volume among Met/Met ...

The brain-derived neurotrophic factor (BDNF) is essential for the survival of neurons in the central nervous system (CNS). The expression of BDNF is regulated by several conditions related to neuronal activity including seizures, normal neuronal depolarization, and long-term potentiation (LTP)--all mechanisms that increase intracellular concentrations of calcium. Increased calcium leads to the occupation of calcium-adenosine-3â€Č,5â€Č-monophosphate (cAMP) response element (CRE) in the BDNF promoter by transcription factors of the CRE-binding protein (CREB) family. The BDNF gene contains four noncoding exons located 5â€Č to the coding region, each of which can be alternatively spliced to the 3â€Č coding exon. BDNF mRNAs that contain the nontranslated exon 3 are the most highly expressed isoform in response to membrane depolarization. In an attempt to understand the processes that contribute to activity-induced neuronal gene-expression, Tao et al. have identified a new mechanism by which BDNF ...

Streptococcus pneumoniae meningitis is a serious inflammatory disease of the central nervous system (CNS) and is associated with high morbidity and mortality rates. The inflammatory processes initiated by recognition of bacterial components contribute to apoptosis in the hippocampal dentate gyrus. Brain-derived neurotrophic factor (BDNF) has long been recommended for the treatment of CNS diseases due to its powerful neuro-survival properties, as well as its recently reported anti-inflammatory and anti-apoptotic effects in vitro and in vivo.. METHODS:. In this study, we investigated the effects of BDNF-related signaling on the inflammatory response and hippocampal apoptosis in ...

Brain-derived neurotrophic factor stimulates energy metabolism in developing cortical neurons - InfoscienceBrain-derived neurotrophic factor stimulates energy metabolism in developing cortical neurons - Infoscience
Brain-derived neurotrophic factor (BDNF) promotes the biochemical and morphological differentiation of selective populations of neurons during development. In this study we examined the energy requirements associated with the effects of BDNF on neuronal differentiation. Because glucose is the preferred energy substrate in the brain, the effect of BDNF on glucose utilization was investigated in developing cortical neurons via biochemical and imaging studies. Results revealed that BDNF increases glucose utilization and the expression of the neuronal glucose transporter GLUT3. Stimulation of glucose utilization by BDNF was shown to result from the activation of Na+/K+-ATPase via an increase in Na+ influx that is mediated, at least in part, by the stimulation of Na+-dependent amino acid transport. The increased Na+-dependent amino acid uptake by BDNF is followed by an enhancement of overall protein synthesis associated with the differentiation of cortical neurons. Together, these data demonstrate the

Antiepileptic drugs provide neuroprotection in several animal models of brain damage, including those induced by status epilepticus (SE). The mechanisms involved in this action are unknown, but neurotrophic factors such as brain-derived neurotrophic factor (BDNF) may play a role. In this study we investigated the changes in BDNF levels in rats in which SE had been induced by pilocarpine injection (400 mg/kg i.p.) and continued for several hours (unprotected group). In other animals (protected groups), SE was suppressed after 30 min by intraperitoneal injection of either diazepam (10 mg/kg) + pentobarbital (30 mg/kg) or paraldehyde (0.3 mg/kg). In diazepam + pentobarbital-treated rats the hippocampal damage caused by SE was significantly lower (p , 0.05) than in unprotected animals. In addition, 2 and 24 h after pilocarpine injection, the levels of BDNF mRNA were moderately increased in the unprotected group, but super-induced in protected animals, especially in the neocortex and hippocampus.

STAT3-BDNF-TrkB signalling promotes alveolar epithelial regeneration after lung injury | Nature Cell BiologySTAT3-BDNF-TrkB signalling promotes alveolar epithelial regeneration after lung injury | Nature Cell Biology
Alveolar epithelial regeneration is essential for recovery from devastating lung diseases. This process occurs when type II alveolar pneumocytes (AT2 cells) proliferate and transdifferentiate into type I alveolar pneumocytes (AT1 cells). We used genome-wide analysis of chromatin accessibility and gene expression following acute lung injury to elucidate repair mechanisms. AT2 chromatin accessibility changed substantially following injury to reveal STAT3 binding motifs adjacent to genes that regulate essential regenerative pathways. Single-cell transcriptome analysis identified brain-derived neurotrophic factor (Bdnf) as a STAT3 target gene with newly accessible chromatin in a unique population of regenerating AT2 cells. Furthermore, the BDNF receptor tropomyosin receptor kinase B (TrkB) was enriched on mesenchymal alveolar niche cells (MANCs). Loss or blockade of AT2-specific Stat3, Bdnf or mesenchyme-specific TrkB compromised repair and reduced Fgf7 expression by niche cells. A TrkB agonist improved

We investigated whether Ύ-opioid receptor (DOR)-induced neuroprotection involves the brain-derived neurotrophic factor (BDNF) pathway. We studied the effect of DOR activation on the expression of BDNF and other proteins in the cortex of C57BL/6 mice exposed to hypoxia (10% of oxygen) for 1-10 days. The results showed that: (1) 1-day hypoxia had no appreciable effect on BDNF expression, while 3- and 10-day hypoxia progressively decreased BDNF expression, resulting in 37.3% reduction (p < 0.05) after 10-day exposure; (2) DOR activation with UFP-512 (1 mg/kg, i.p., daily) partially reversed the hypoxia-induced reduction of BDNF expression in the 3- or 10-day exposed cortex; (3) DOR activation partially reversed the hypoxia-induced reduction in functional TrkB (140-kDa) and attenuated hypoxia-induced increase in truncated TrkB (90-kDa) in the 3- or 10-day hypoxic cortex; and (4) prolonged hypoxia (10 days) significantly increased TNF-α level and decreased CD11b expression in the cortex, which was

Presynaptic and postsynaptic NMDA receptors mediate distinct effects o by Joseph Cruz MadaraPresynaptic and postsynaptic NMDA receptors mediate distinct effects o by Joseph Cruz Madara
Brain-derived neurotrophic factor (BDNF) has long been known as a trophic factor involved in survival, differentiation, and maintenance of neuronal populations in the central nervous system. In addition to these effects, BDNF has emerged as a major activity-dependent regulator of synaptic transmission and plasticity in many brain areas, most notably the neocortex and hippocampus. Pre- and postsynaptic localization of BDNF and its cognate receptor, tropomyosin receptor kinase B (TrkB) at glutamate synapses in particular, make it an ideal candidate for rapidly fine-tuning excitatory transmission and modulating the ability of synapses to undergo activity-dependent plasticity. Furthermore, N-methyl-D-asparate (NMDA) receptors, which play an important role in some forms of plasticity, are a primary target of BDNF-TrkB receptor signaling. Although BDNF appears to have pre- and postsynaptic effects on glutamatergic transmission, consistent with localization of TrkB receptors to axon terminals and dendritic

Background: Antidepressant drugs (ADs) have been shown to activate BDNF (brain-derived neurotrophic factor) receptor TrkB in the rodent brain but the mechanism underlying this phenomenon remains unclear. ADs act as monoamine reuptake inhibitors and after prolonged treatments regulate brain bdnf mRNA levels indicating that monoamine-BDNF signaling regulate AD-induced TrkB activation in vivo. However, recent findings demonstrate that Trk receptors can be transactivated independently of their neurotrophin ligands. Methodology: In this study we examined the role of BDNF, TrkB kinase activity and monoamine reuptake in the AD-induced TrkB activation in vivo and in vitro by employing several transgenic mouse models, cultured neurons and TrkB-expressing cell lines. Principal Findings: Using a chemical-genetic TrkB(F616A) mutant and TrkB overexpressing mice, we demonstrate that ADs specifically activate both the maturely and immaturely glycosylated forms of TrkB receptors in the brain in a TrkB kinase ...

Could an alternative version of your brain-derived neurotropic factor be an excuse for your failed road test?. According to research published in the Journal, Cerebral Cortex, by Stephanie McHughen et.al., a key SNP in BDNF (valine 66 mutated to methionine) impacts learning and memory functions, cognitive tools which happen to be crucial for operating an automobile.. During one of the described experiments, subjects were seated at a computer, with attached steering wheel as they had to keep the virtual car on a black line in the center of the screen. Subjects got to learn the driving circuit by following the car on 15, 60 second trials. While both groups of subjects (those who had the normal valine allele, and those with the val66met SNP) started at similar levels of ability, and showed short term learning. During the trials however, val66met subjects showed less learning, and made more mistakes while learning. By day 5 of training, those with the val66met allele showed less ability to retain ...

Neurotrophic factors: important regulators of nociceptive function. - Nuffield Department of Clinical NeurosciencesNeurotrophic factors: important regulators of nociceptive function. - Nuffield Department of Clinical Neurosciences
Neurotrophic factors have an established developmental role in regulating the survival and specification of sensory neurons. However, these factors continue to exert an important influence on sensory neurons throughout the postnatal period and into adult life. In adulthood, approximately one-half of nociceptors are dependent on nerve growth factor (NGF) for trophic support, whereas the other half are sensitive to glial cell line-derived neurotrophic factor (GDNF). It is now known that many chronic pain states are maintained by widespread changes in the anatomy, neurochemistry, and function of the sensory nervous system both at the level of the primary sensory neuron and the dorsal horn of the spinal cord. Trophic factors appear to orchestrate many of these dynamic changes. This review highlights some of the key roles played by these molecules and in particular the role of NGF in the peripheral sensitization of nociceptors and brain-derived neurotrophic factor (BDNF) as a central pain modulator.

Endocytosis of Trk (tropomyosin-related kinase) receptors is critical for neurotrophin signal transduction and biological functions. However, the mechanism governing endocytosis of TrkB (tropomyosin-related kinase B) and the specific contributions of TrkB endocytosis to downstream signaling are unknown. In this study, we report that blocking clathrin, dynamin, or AP2 in cultured neurons of the central nervous system inhibited brain-derived neurotrophic factor (BDNF)-induced activation of Akt but not ERK. Treating neurons with the clathrin inhibitor monodansylcadaverine or a peptide that blocks dynamin function specifically abrogated Akt pathway activation in response to BDNF but did not affect the response of other downstream effectors or the up-regulation of immediate early genes neuropeptide Y and activity-regulated cytoskeleton-associated protein. Similar effects were found in neurons expressing small interfering RNA to silence AP2 or a dominant negative form of dynamin that inhibits ...

Neurotrophic factors - WikipediaNeurotrophic factors - Wikipedia
Neurotrophic factors (NTFs) are a family of biomolecules - nearly all of which are peptides or small proteins - that support the growth, survival, and differentiation of both developing and mature neurons.[1][2][3] Most NTFs exert their trophic effects on neurons by signaling through tyrosine kinases,[2] usually a receptor tyrosine kinase. In the mature nervous system, they promote neuronal survival, induce synaptic plasticity, and modulate the formation of long-term memories.[2] Neurotrophic factors also promote the initial growth and development of neurons in the central nervous system and peripheral nervous system, and they are capable of regrowing damaged neurons in test tubes and animal models.[1][4] Some neurotrophic factors are also released by the target tissue in order to guide the growth of developing axons. Most neurotrophic factors belong to one of three families: (1) neurotrophins, (2) glial cell-line derived neurotrophic factor family ligands (GFLs), and (3) neuropoietic ...

Purpose: : During NMDA-induced cell death in the neural retina, there is an elevation of the nuclear isoform of CaMKIIα (CaMKIIαB). This result leads to the question of how CaMKIIαB might be involved in either a cell death or cell survival pathway, for example, in retinal ganglion cells (RGCs). The purpose of this study is to investigate if CaMKIIα regulates BDNF expression in RGCs. Methods: : Highly purified RGCs or dissociated retinal cells were obtained from P6-8 SD rat eyes and treated with glutamate (200-1000uM) for the indicated times. Glutamate cytotoxicity on RGCs and localization of CaMKIIα was determined by cell counting and immunostaining, respectively. To identify the role of CaMKIIα in regulating BDNF expression, CaMKIIαB expression vector was constructed and over-expressed in cells of the RGC-5 cell line, and cell viability was assayed. Specific siRNAs to knock down CaMKIIαB or CaMKIIα were then tested in CaMKIIαB-transfected or non-transfected RGC-5 cells. The siRNAs ...

Ionotropic glutamate receptors mediate most excitatory synaptic transmission in mammalian brain, and play important roles in neuronal development and synaptic plasticity. In particular, long-term potentiation (LTP) and long-term depression (LTD) are generally considered to represent cellular mechanisms involved in certain forms of learning and memory. Calpain is a calcium-dependent neutral protease that plays significant roles in synaptic plasticity, cell motility, as well as in various forms of neurodegeneration. We compared the rates of calpain-mediated truncation of GluR1 and GluR2 subunits with those of GluR1 phosphorylated at serine 831 or serine 845, and GluR2 phosphorylated at serine 880. Rat brain membranes were treated with calpain and calcium and levels of total and phosphorylated GluR1 and GluR2 subunits were analyzed by western blots. Rates of calpain-mediated truncation of phosphorylated GluR1 (either at serine 831 or 845) were much slower than for total GluR1. On the other hand, ...

Nicotine exposure enhances Pavlovian conditioned approach (PCA), or the learned approach to reward-predictive cues. While females show elevated approach to conditioned stimuli compared to males, potentially indicating heightened addiction vulnerability, it is unknown how sex may interact with nicotine to influence approach behavior. Additionally, brain-derived neurotrophic factor (BDNF) levels can be altered significantly after repeated nicotine exposure, suggesting a potential mechanism contributing to nicotine-induced behavioral phenotypes. The present study investigated the role of sex on nicotine-induced changes to stimulus-response behavior and associated BDNF protein levels. Male and female rats were exposed to nicotine (0.4 mg/kg, subcutaneously) or saline 15 min prior to each PCA session. PCA training consisted of 29 sessions of 15 trials, in which a 30-s cue presentation ended concurrently with a sucrose reward (20% w/v in water, 100 ÎŒL), and a 120-s variable intertrial interval occurred

Neurotrophin signaling impacts development and health of oligodendrocyte lineage cells. Brain-derived neurotrophic factor (BDNF) has been of particular interest. BDNF increases DNA synthesis in cultured basal forebrain oligodendrocyte progenitors (Vant Veer et al., 2009) and enhances oligodendrocyte differentiation to myelin protein-expressing cells (Du et al., 2006). Moreover, BDNF deficient mice exhibit deficits in progenitors and myelin protein expression (Vondran et al., 2010) and the conditional knock-out of the BDNF receptor TrkB from mature, MBP+ oligodendrocytes results in reduced myelin thickness in both the spinal cord and the corpus callosum (Wong et al., 2013).. These effects may be relevant to in vivo demyelination. For example, in the cuprizone demyelination model expression of BDNF is decreased in the corpus callosum, and animals deficient in BDNF exhibit a more severe loss of myelin protein in the lesioned corpus callosum than do their wild-type littermates (VonDran et al., ...

Infusing brain-derived neurotrophic factor (BDNF) into the infralimbic (IL) prefrontal cortex is capable of inducing extinction. Little is known, however, about the circuits mediating BDNF effects on extinction or the extent to which extinction requires BDNF in IL. Using local pharmacological infusion of BDNF protein, or an antibody against BDNF, we found that BDNF in the IL, but not prelimbic (PL) prefrontal cortex, is both necessary and sufficient for fear extinction. Furthermore, we report that BDNF in IL can induce extinction of older fear memories (14 days) as well as recent fear memories (1 day). Using immunocytochemistry, we show that BDNF is increased in the ventral hippocampus (vHPC), but not IL or PL, following extinction training. Finally, we observed that infusing BDNF into the vHPC increased the firing rate of IL, but not PL neurons in fear conditioned rats. These findings indicate that an extinction-induced increase in BDNF within the vHPC enhances excitability in IL targets, ...

Cognitive exercise can also increase a specific type of fertilizer called brain-derived neurotrophic factor (BDNF) and increases synaptogenesis. The question then arises, What if these therapy activities were combined? For example, what if you had someone walking on a treadmill while performing some type of cognitive activity so that you stimulate neurotrophic factors on two fronts? One study actually did find that such a combination of activities can exponentially enhance the production of neurotrophic factors. ...

AU - Kutiyanawalla, Ammar. AU - Turecki, Gustavo. AU - Pillai, Anilkumar. PY - 2014/7. Y1 - 2014/7. N2 - Brain derived neurotrophic factor (BDNF) signaling through its receptor TrkB plays a crucial role in neurodevelopment and plasticity. Stress and glucocorticoids have been shown to alter TrkB signaling in neurons, and defects in TrkB expression have been reported in the prefrontal cortex of suicide subjects. Glucocorticoid treatment has been shown to induce deleterious effects on the neuronal maturation. However, the mechanisms involved in the regulation of TrkB by glucocorticoid during neurodevelopment are not clear. Here we show that acute corticosterone exposure induced posttranslational upregulation of TrkB in primary cortical neurons (days in vitro 4, DIV4), which was blocked by the proteasome ...

MSC engineered to produce BDNF for the treatment of Huntingtons disease | Californias Stem Cell AgencyMSC engineered to produce BDNF for the treatment of Huntingtons disease | Californias Stem Cell Agency
Background: Huntingtons disease (HD) is a genetically inherited, fatal neuropsychiatric disorder which strikes 1/10,000 people. The cause is a repeat expansion in the Huntingtin gene which leads to progressive brain degeneration, ultimately resulting in death after 15-20 years. HD passes from generation to generation. Each child of a parent with HD has a 50% chance of inheriting the HD mutation. There is currently no treatment, therapy or medication that will delay the onset of the disease or slow its progression. All currently available treatments are palliative, which focus on symptom management alone. There is currently no cure for HD. Proposed therapy: We propose a novel therapy for HD: implantation of mesenchymal stem cells engineered to secrete Brain-Derived Neurotrophic Factor (MSC/BDNF). BDNF levels are reduced in the brains of HD patients. BDNF has been shown in numerous transgenic HD mouse studies to prevent cell death and to stimulate the growth and migration of new neurons in the ...

Impairment of TrkB-PSD-95 Signaling in Angelman Syndrome by Cong Cao, Mengia S. Rioult-Pedotti et al.Impairment of TrkB-PSD-95 Signaling in Angelman Syndrome by Cong Cao, Mengia S. Rioult-Pedotti et al.
Angelman syndrome (AS) is a neurodevelopment disorder characterized by severe cognitive impairment and a high rate of autism. AS is caused by disrupted neuronal expression of the maternally inherited Ube3A ubiquitin protein ligase, required for the proteasomal degradation of proteins implicated in synaptic plasticity, such as the activity-regulated cytoskeletal-associated protein (Arc/Arg3.1). Mice deficient in maternal Ube3A express elevated levels of Arc in response to synaptic activity, which coincides with severely impaired long-term potentiation (LTP) in the hippocampus and deficits in learning behaviors. In this study, we sought to test whether elevated levels of Arc interfere with brain-derived neurotrophic factor (BDNF) TrkB receptor signaling, which is known to be essential for both the induction and maintenance of LTP. We report that TrkB signaling in the AS mouse is defective, and show that reduction of Arc expression to control levels rescues the signaling deficits. Moreover, the association

Research Summary. Research in my laboratory is centered around signalling events, particularly those that involve intracellular Ca2+ and the major Ca2+ -binding regulatory protein calmodulin. Two systems we are investigating are the regulation of protein synthesis and the control of endocytosis by Ca2+, both of which involve (different) calmodulin-regulated events. We are also interested in the mechanism of action of neurotrophic factors like nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF) as they relate to the effects of these proteins on CNS neurons. Part of the action of these factors also involves Ca2+. Current projects. Neurotrophic factors and CNS neurons We have shown that primary cultures of rat embryonic hippocampal neurons can be used for biochemical investigations of the signal transduction pathways activated by BDNF and neurotrophin-3. These cells homogeneously express the receptors for these neurotrophins (receptor tyrosine kinases called TrkB and TrkC), and ...

Neurotrophins promote the survival and development of neurons in the cerebellum of hypothyroid rats in vivo. | JCBNeurotrophins promote the survival and development of neurons in the cerebellum of hypothyroid rats in vivo. | JCB
The development of cerebellar cortex is strongly impaired by thyroid hormone (T3) deficiency, leading to altered migration, differentiation, synaptogenesis, and survival of neurons. To determine whether alteration in the expression of neurotrophins and/or their receptors may contribute to these impairments, we first analyzed their expression using a sensitive RNAse protection assay and in situ hybridization; second, we administered the deficient neurotrophins to hypothyroid animals. We found that early hypothyroidism disrupted the developmental pattern of expression of the four neurotrophins, leading to relatively higher levels of NGF and neurotrophin 4/5 mRNAs and to a severe deficit in NT-3 and brain-derived neurotrophic factor (BDNF) mRNA expression, without alteration in the levels of the full-length tyrosine kinase (trk) B and trkC receptor mRNAs. Grafting of P3 hypothyroid rats with cell lines expressing high levels of neurotrophin 3 (NT-3) or BDNF prevented hypothyroidism-induced cell ...

Effects of BDNF Polymorphisms on Antidepressant ActionEffects of BDNF Polymorphisms on Antidepressant Action
Given that both clinical and preclinical studies suggest that BDNF may be involved in the therapeutic action of antidepressants, BDNF appears to be a good candidate gene for the pharmacogenetic study of antidepressants. In our 2003 study on 110 MDD outpatients, we examined the association between the BDNF Val66Met polymorphism and response to 4-week antidepressant (fluoxetine) treatment.17 A trend (p=0.086) to higher total HAM-D-score percentage change was noted for the Val/Met-heterozygote patients in comparison to those bearing the homozygote (Val/Val or Met/Met). While similar findings have been reported in some of the subsequent studies of this polymorphism and the antidepressant response23,24, other studies demonstrated a better response in subjects with the Met variant25-27 or they found no association at all (Table 1).28,29 The inconsistencies in these findings might be due to the small sample sizes used in some of the studies. They could also have arisen as the result of differences in ...

Brain-derived neurotrophic factor (BDNF), nerve growth factor-induced gene A (NGFI-A) and corticosteroid receptors (mineralocorticoid receptor, MR; glucocorticoid receptor, GR) have been demonstrated to be involved in brain plasticity. The purpose of this thesis was to determine if post-ischemic housing conditions had a significant effect on transcription and/or translation of BDNF, NGFI-A and corticosteroid receptors. We found that BDNF gene was down regulated in EE-housed rats when compared to the rats housed in standard cages at 2~12 days after cortical brain ischemia in peri-infarct cortex, contralateral cortex and bilateral hippocampus.

Objective To investigate the association between chronic unpredictable mild stress (CUMS)-induced depressive-like behavior in rats and expressions of brain-derived neurotrophic factor (BDNF) and S100ß in the hippocampal and prefrontal cortex. Methods Rats were randomly assigned to three groups:saline control group,saline+CUMS group,and citalopram +CUMS group. CUMS was used for depression modeling in rats. Depressive-like behavior in rats were evaluated by open-field test,sucrose preference test,and novel object recognition test. S100ß and BDNF expressions were tested by enzyme-linked immunosorbent assay. Results Rats in the saline+CUMS group had significantly lower score in sucrose preference [(52.48±13.14)%],basic motor tasks [(845.8±371.4)s],fine motor tasks [(565.6±211.9)s],and longer resting time [(282.6±11.8)s] compared to the control group [(84.30±6.15)% (t=7.49,P=0.000),(1239.1±281.6)s (t=2.83,P=0.008),(801.8±150.9)s (t=3.05,P=0.003),(268.2±12.8)s (t=2.72,P=0.001)].

Although previous studies of Huntingtons disease (HD) have addressed many potential mechanisms of striatal neuron dysfunction and death, it is also known based on clinical findings that cortical function is dramatically disrupted in HD. With respect to disease etiology, however, the specific molecular and neuronal circuit bases for the cortical effects of mutant huntingtin (htt) have remained largely unknown. In the present work we studied the relation between the molecular effects of mutant htt fragments in cortical cells and the corresponding behavior of cortical neuron microcircuits using a novel cellular model of HD. We observed that a transcript-selective diminution in activity-dependent BDNF expression preceded the onset of a synaptic connectivity deficit in ex vivo cortical networks, which manifested as decreased spontaneous collective burst-firing behavior measured by multi-electrode array substrates. Decreased BDNF expression was determined to be a significant contributor to ...

Additionally, experience of an enriched environment brings about cellular changes in neurons, including synapse creation in the hippocampus, which is responsible for memory, and an increase in neurotrophins essential for neural function such as brain-derived neurotrophic factor (BDNF). However, the mechanism of these cellular and behavioral changes remained unknown.. Professor Nobutaka Hirokawa and his colleagues at the University of Tokyos Graduate School of Medicine have shown for the first time that the motor protein KIF1A, known to be involved in the transport of compounds essential for neural signaling, has a vital role in memory and learning enhancement due to an enriched environment.. The research group determined that the quantity of BDNF and KIF1A was elevated in the hippocampi of mice raised in an enriched environment. However, even when raised in an enriched environment, a genetically-engineered mouse with a reduced ability to express KIF1A showed no increase in hippocampal synapse ...

Premenstrual dysphoric disorder (PMDD) is the prototypical sex-specific disorder in which symptom onset and offset require a particular hormonal milieu and for which there is moderate heritability. The present study investigated brain emotion processing in PMDD and healthy controls, as well as functional polymorphisms in two candidate genes for PMDD, the serotonin transporter (5-HTT) and brain derived neurotrophic factor (BDNF). The 5-HTT linked polymorphic region (5-HTTLPR) and BDNF Val66Met polymorphisms were genotyped in 31 patients with PMDD and 31 healthy controls. A subset of 16 patients and 15 controls participated in two functional magnetic resonance imaging-sessions performing an emotion processing task; once in the mid-follicular, and once in the late luteal phase which corresponds with maximum severity of mood symptoms. Genotypes were not directly associated with PMDD. A main effect of group was found in the whole brain analysis, with patients having lower activation of the pre-genual ...

RESULTS: Amantadine had antidepressant-like effects in animal models and appeared to potentiate the antidepressant effects of other antidepressants. These preclinical findings have received some support from the results of small open-label clinical trials, suggesting that amantadine can reduce depressive symptomatology and potentiate the antidepressant effects of monoaminergic drugs. In addition to its glutamatergic and dopaminergic effects, the potential antidepressant-like effects of amantadine have been linked to molecular and cellular actions, such as increased expression of neurotrophic factors (e.g., brain-derived neurotrophic factor), activation of σ1 receptors, decreased corticosterone levels, and decreased inflammatory response to stress ...

Yoga can improve the physical and mental health of the elderly - Live Love Laugh FoundationYoga can improve the physical and mental health of the elderly - Live Love Laugh Foundation
Depression in the elderly is also very difficult to detect, as the symptoms may be written off as signs of aging. Studies show that the risk of developing depression in the lifetime among the elderly population is 16.5 %, with women being at a higher risk than men. A person in depression has increased levels of the stress hormone cortisol. A three month practice of a validated yoga module reduces the level of cortisol in persons with depression. Studies have proved that yoga therapy helps reduce anxiety, depression and improves quality of life, when compared to exercise done by women with depression. As a lifestyle practice, yoga has been beneficial to the elderly in many ways. Brain Derived Neuro trophic Factor (BDNF) is a neuro-protective chemical which is highly active in the hippocampus. Persons with depression suffer from low level of BDNF. A study showed that practicing yogasana and pranayama for three months increased the serum BDNF concentration in persons with depression. Yoga and ...

The Mental Health Dangers of Birth HypoxiaThe Mental Health Dangers of Birth Hypoxia
However, it is not clear why hypoxia increases the risk for schizophrenia. The November 1st issue of Biological Psychiatry includes an article by researchers who show that the presence of a specific indicator of fetal distress following hypoxia was more likely to be present among people who later develop schizophrenia. Their findings suggest that the inability of a high-risk fetus to respond adequately to metabolic stresses that it faces in the womb may contribute to its later risk for developing schizophrenia.. Specifically, the authors analyzed levels of an important neuroprotective protein - brain-derived neurotrophic factor (BDNF) - in umbilical cord and maternal blood serum samples obtained at the time of birth and stored in a repository for 45-50 years. They then compared the levels of BDNF found among those individuals who had developed schizophrenia during their lifetime to control subjects, i.e., those individuals who did not develop the disorder.

ALS Research | Physics Forums - The Fusion of Science and CommunityALS Research | Physics Forums - The Fusion of Science and Community
Clinical trials in amyotrophic lateral sclerosis (ALS) have been conducted for over half a century now and have incorporated a wide variety of drugs. Most of these trials have had negative results and a cure remains elusive. The explosion in our understanding of molecular biology and parallel developments in clinical epidemiology have opened up a vast number of novel therapeutic strategies. However, advances in statistical analysis, computing, and global communications have also put greater pressure on scientific investigators to improve the design and implementation of clinical trials so that they permit rigorous testing of hypotheses within a solid ethical framework. This article documents the first published trial for all drugs tried clinically in the treatment of ALS, focusing in more detail on the large, multicenter trials of recent years, namely those involving riluzole, ciliary neurotrophic factor, insulin-like growth factor-I, brain-derived neurotrophic factor, and SR57746A.
