Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL): a case report with review of literature. (1/101)

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is an inherited arterial disease, commonly overlooked or misdiagnosed. We report a case of CADASIL in a 51 years old woman who presented with progressive subcortical dementia, recurrent ischemic events and seizures in the absence of known vascular risk factors of five years' duration. Her mother had a history of similar illness. Magnetic resonance imaging (MRI) of brain revealed subcortical and deep white matter hyperintense lesions within the cerebral white matter on T2-weighted images. DNA mutation of Notch 3 gene confirmed the diagnosis of CADASIL.  (+info)

Long-term prognosis and causes of death in CADASIL: a retrospective study in 411 patients. (2/101)

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a hereditary angiopathy caused by mutations in the NOTCH3 gene. The clinical course is highly variable. Little is known about the long-term prognosis and the causes of death in CADASIL patients. Likewise, the impact of gender and NOTCH3 genotype on disease progression remains largely unexplored. We identified 411 subjects (196 men, 215 women) with a definite diagnosis of CADASIL. Age at onset for stroke, immobilization and death as well as the causes of death and clinical status at onset of the cause of death were determined systematically. Weibull regression models were used to calculate times to event, with gender and NOTCH3 genotype as covariates. At the time of the study, 73 patients had died. The median age at onset for stroke was 50.7 years [95% confidence interval (CI) = 48.2-53.1 years] in men and 52.5 years (95% CI = 50.0-54.9 years) in women (P = n.s.). The median ages at onset for inability to walk without assistance [men 58.9 years (95% CI = 56.6-61.3 years); women 62.1 years (59.7-64.4 years)], bedriddenness [men 62.1 years (59.6-64.7 years), women 66.5 years (63.9-69.1 years); and death [men 64.6 years (61.7-67.6 years); women 70.7 years (67.6-73.9 years)] were significantly lower in men than in women (all P < or = 0.01). The median survival time of men was significantly shorter than expected from German life tables (64.6 versus 69.3 years, P = 0.01). In contrast, the median survival time of women was not significantly reduced (70.7 versus 72.2 years). The C117F mutation was associated with a lower age at death and the C174Y mutation with a lower age at onset for stroke, immobilization and death (adjusted P values <0.05). At onset of the cause of death, 78% of the subjects were completely dependent. Sixty-three per cent were confined to bed. Pneumonia was the most frequent cause of death (38%), followed by sudden unexpected death (26%) and asphyxia (12%). We conclude that male sex is a risk factor for early immobilization and death in CADASIL. Our findings suggest possible genotype-phenotype correlations with regard to disease progression. The data presented may serve as source material for counselling CADASIL patients and for designing future interventional trials.  (+info)

Detection of the founder effect in Finnish CADASIL families. (3/101)

Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited cerebrovascular disease characterized by brain infarcts, cognitive decline and dementia. The disease is caused by at least 91 missense mutations, four deletions and one splice site mutation in the NOTCH3 gene, which maps to 19p13.1. In 18 out of the 21 Finnish CADASIL families so far identified, the causative mutation is an arginine to cysteine substitution in position 133 (R133C). Most of the families carrying this mutation originate from the western coast of Finland, thus suggesting a founder effect. No previous reports of a founder effect in CADASIL have been published. We haplotyped 60 patients from these 18 families for 10 microsatellite markers in order to determine whether the families descend from a common ancestor. We found a similar haplotype linked to the mutation in all 18 pedigrees, which indicates a single common ancestor for all the Finnish R133C families. The age analysis of the founder mutation places the introduction of the mutation in the late 1600s or early 1700s.  (+info)

Scanning laser Doppler flowmetry shows reduced retinal capillary blood flow in CADASIL. (4/101)

BACKGROUND AND PURPOSE: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a progressive systemic nonatherosclerotic angiopathy which causes ischemic strokes and vascular subcortical dementia. A cross-sectional study was performed to examine the retinal vascular caliber and blood flow in CADASIL. METHODS: Scanning laser Doppler flowmetry was used in a case-control study (11 patients and controls) of peripapillary retinal circulation. Automated full-field perfusion image analysis was used to analyze the flow data. Retinal vessel calibers were measured from retinal images acquired with scanning laser ophthalmoscopy. The caliber of the superior and inferior temporal retinal artery and vein were measured 1 and 2 mm from the disc rim, and the mean values were used for analysis. RESULTS: Retinal capillary peak systolic flow (mean, 249 versus 311 arbitrary unit [AU]; P=0.072) was lower, and mean capillary flow (mean, 184 versus 224 AU; P=0.12) and minimum diastolic flow (mean, 105 versus 132 AU; P=0.16) tended to be lower in patients than in controls. No significant difference in the calibers of proximal retinal arteries (mean, 104 versus 108 microm) and veins (mean, 150 versus 145 microm) was found between the patients and controls. CONCLUSIONS: Retinal capillary blood flow is mild to moderately reduced in CADASIL but that does not appear to cause major ischemic injury. Such reduction is analogous to that in the cerebral cortex in CADASIL patients with which retina appears to share its relative sparing from severe arterial ischemic tissue damage.  (+info)

Impaired vascular mechanotransduction in a transgenic mouse model of CADASIL arteriopathy. (5/101)

BACKGROUND AND PURPOSE: CADASIL is an inherited small-vessel disease responsible for lacunar strokes and cognitive impairment. The disease is caused by highly stereotyped mutations in Notch3, the expression of which is highly restricted to vascular smooth muscle cells (VSMCs). The underlying vasculopathy is characterized by degeneration of VSMCs and the accumulation of granular osmiophilic material (GOM) and Notch3 protein within the cell surface of these cells. In this study, we assessed early functional changes related to the expression of mutant Notch3 in resistance arteries. METHODS: Vasomotor function was examined in vitro in arteries from transgenic mice that express a mutant Notch3 in VSMC. Tail artery segments from transgenic and normal wild-type male mice were mounted on small-vessel arteriographs, and reactivity to mechanical (flow and pressure) forces and pharmacological stimuli were determined. Mice were studied at 10 to 11 months of age when VSMC degeneration, GOM deposits, and Notch3 accumulation were not yet present. RESULTS: Passive arterial diameter, contraction to phenylephrine, and endothelium-dependent relaxation to acetylcholine were unaffected in transgenic mice. By contrast, flow-induced dilation was significantly decreased and pressure-induced myogenic tone significantly increased in arteries from transgenic mice compared with wild-type mice. CONCLUSIONS: This is the first study to our knowledge providing evidence that mutant Notch3 impairs selectively the response of resistance arteries to flow and pressure. The data suggest an early role of vascular dysfunction in the pathogenic process of the disease.  (+info)

Impaired cerebral vasoreactivity in a transgenic mouse model of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy arteriopathy. (6/101)

BACKGROUND AND PURPOSE: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is an inherited small vessel disease causing stroke and dementia. The disease is caused by highly stereotyped mutations in NOTCH3, which is restrictively expressed in vascular smooth muscle cells (VSMCs). The mechanisms of compromised cerebral hemodynamics in CADASIL remain to be elucidated. We tested the hypothesis that mutant NOTCH3 impairs the vasomotor function of cerebral vessels. METHODS: Vasomotor function was examined in vivo in transgenic mice expressing a mutant NOTCH3 in VSMCs (TgNotch3R90C). Mice develop an age-dependent arteriopathy similar to that seen in CADASIL, without brain parenchyma lesions. Using laser-Doppler flowmetry, we assessed in awake TgNotch3R90C mice and wild-type littermates the cerebrovascular reactivity to 2 potent vasodilator stimuli (acetazolamide and hypercapnia) and cerebral blood flow (CBF) autoregulation during stepwise blood pressure elevations and reductions. Mice were studied at 18 months of age, when the CADASIL features are apparent, and at 10 months of age, before their appearance. RESULTS: Eighteen-month-old TgNotch3R90C mice showed reduced responses to hypercapnia and acetazolamide, higher cerebrovascular resistance during hypertension, and their lower limit of CBF autoregulation was shifted to higher blood pressures. Cerebrovascular responses were similarly impaired in 10-month-old TgNotch3R90C mice. CONCLUSIONS: Cerebrovascular reactivity is compromised early in TgNotch3R90C mice. The data show an impaired autoregulation and are suggestive of a decreased relaxation or increased resistance of cerebral vessels. Our findings indicate that vascular dysfunction is an early pathogenic event that may promote the subsequent development of brain ischemia in CADASIL.  (+info)

The spectrum of Notch3 mutations in 28 Italian CADASIL families. (7/101)

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is a cause of hereditary cerebrovascular disease. It results from mutations in the Notch3 gene, a large gene with 33 exons. A cluster of mutations around exons 3 and 4 was originally reported and limited scanning of these exons was suggested for the diagnosis in most cases. OBJECTIVE: To report Notch3 mutation analysis in 28 unrelated Italian CADASIL families from central and south Italy. RESULTS: The highest rate of mutations was found in exon 11 (21%) and only 18% of mutations were in exon 4. This may be related to the peculiar distribution of Notch3 mutations in the regions of origin of the families. CONCLUSIONS: The results suggest that limited scanning of exons 3 and 4 is inadvisable in CADASIL cases of Italian origin.  (+info)

The prevalence of cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) in the west of Scotland. (8/101)

BACKGROUND: Cerebral autosomal dominant arteriopathy with subcortical infarcts and leucoencephalopathy (CADASIL) is caused by mutations of the Notch3 gene on 19p13. Varying phenotypic expression leads to under recognition and misdiagnosis. Prevalence therefore remains uncertain. We sought to estimate the prevalence of CADASIL in the west of Scotland. METHODS: A register for CADASIL was established at a regional neurosciences centre in 2002. All patients with genetically (exons 3, 4, 5, and 6) or histologically confirmed CADASIL residing in two defined administrative health areas were identified. Pedigree members at varying risk of carrying the mutation were also identified and the number of probable Notch3 mutation carriers in the defined population was predicted. Prevalence was calculated for definite CADASIL cases, with and without probable carrier numbers, based upon adult population figures from the 2002 national census. RESULTS: Twenty two individuals from seven pedigrees with confirmed CADASIL and resident in the defined geographical area were identified, yielding a prevalence of 1.98 (95% confidence interval 1.24-3.00) per 100 000 adults. An additional 37 individuals were predicted to be carriers of the Notch3 mutation, yielding a probable mutation prevalence of 4.14 (3.04-5.53) per 100,000 adults. CONCLUSIONS: The prevalence of genetically proven CADASIL was 1.98 per 100,000 adults in the defined population. This figure underestimates disease burden.  (+info)

BACKGROUND AND PURPOSE: White matter hyperintensities (WMH) on MRI are a quantitative marker for sporadic cerebral small vessel disease and are highly heritable. To date, large-scale genetic studies have identified only a single locus influencing WMH burden. This might in part relate to biological heterogeneity of sporadic WMH. The current study searched for genetic modifiers of WMH volume in cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), a monogenic small vessel disease.. METHODS: We performed a genome-wide association study to identify quantitative trait loci for WMH volume by combining data from 517 CADASIL patients collected through 7 centers across Europe. WMH volumes were centrally analyzed and quantified on fluid attenuated inversion recovery images. Genotyping was performed using the Affymetrix 6.0 platform. Individuals were assigned to 2 distinct genetic clusters (cluster 1 and cluster 2) based on their genetic background.. RESULTS: ...

SUD has been reported to account for 26% of cases of premature mortality in patients with CADASIL.6 To explain such a high incidence of SUD, we investigated risk factors for life-threatening arrhythmias (reduced heart rate variability, sympathetic overactivity, and QTc prolongation) in these patients.. The results of this study showed statistically significant reduction in all HRV frequency-domain parameters associated with a higher LF/HF ratio in CADASIL patients compared with normal subjects. These data are consistent with autonomic derangement and suggest that sympathetic and parasympathetic autonomic cardiovascular regulatory systems may both be impaired in these patients.20 Transient or persistent abnormalities in sympathetic-parasympathetic interactions have been shown to favor arrhythmia in patients with heart disease as well as in the general population.21 In this respect, primary sympathetic hyperactivity and vagal tone suppression may both predispose to life-threatening cardiac ...
No specific treatment for CADASIL is available. While most treatments for CADASIL patients symptoms - including migraine and stroke - are similar to those without CADASIL, these treatments are almost exclusively empiric, as data regarding their benefit to CADASIL patients is limited.[14] Antiplatelet agents such as aspirin, dipyridamole, or clopidogrel might help prevent strokes; however, anticoagulation may be inadvisable given the propensity for microhemorrhages.[15] Control of high blood pressure is particularly important in CADASIL patients.[14] Short-term use of atorvastatin, a statin-type cholesterol-lowering medication, has not been shown to be beneficial in CADASIL patients cerebral hemodynamic parameters,[16] although treatment of comorbidities such as high cholesterol is recommended.[17] Stopping oral contraceptive pills may be recommended.[18] Some authors advise against the use of triptan medications for migraine treatment, given their vasoconstrictive effects,[19] although this ...
Objective Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is a small vessel disease of the brain caused by mutations in the NOTCH3 gene. CADASIL progresses, in some cases, to subcortical dementia with a particular cognitive impairment. Different diseases in the dementia spectrum share a central cholinergic and sensorimotor plasticity alteration. We aimed to study different intracortical circuits and sensorimotor plasticity in CADASIL patients using transcranial magnetic stimulation protocols, and to determine whether these characteristics correlated with the results of clinical neuropsychological evaluation.. ...

Notch signaling is a very conservative system of cell-cell communications playing an essential role in vascular development and human vascular diseases. One of such diseases is a hereditary vascular degenerative disorder known as cerebral autosomal dominant arteriopathy with subcortical infarct and leukoencephalopathy (CADASIL). The disorder is caused by mutations in the NOTCH 3 gene encoding a transmembrane receptor of the same name present in vessels only on vascular smooth muscle cells and pericytes. The disease involves mainly small arteries and capillaries in which degeneration and loss of cells expressing Notch 3 receptor is observed. In the affected vessels accumulation of Notch 3 extracellular domain (N3-ECD) and granular osmiophilic material (GOM) containing N3-ECD are also found. Although pathogenesis of CADASIL is still unknown there are two main distinct hypotheses concerning its development. The first of them assumes that the disease is caused by dysfunction of the mutated Notch 3 ...
Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy (CADASIL) is the most common hereditary vascular dementia. CADASIL is a systemic disease of small and medium-sized arteries although the symptoms are almost exclusively neurological, including migraineous headache, recurrent ischemic episodes, cognitive impairment and, finally, subcortical dementia. CADASIL is caused by over 170 different mutations in the NOTCH3 gene, which encodes a receptor expressed in adults predominantly in the vascular smooth muscle cells. The function of NOTCH3 is not crucial for embryonic development but is needed after birth. NOTCH3 directs postnatal arterial maturation and helps to maintain arterial integrity. It is involved in regulation of vascular tone and in the wound healing of a vascular injury. In addition, NOTCH3 promotes cell survival by inducing expression of anti-apoptotic proteins. NOTCH3 is a membrane-spanning protein with a large extracellular domain (N3ECD) ...
This mutation was found in four members of a family in whom affected members presented with dementia, spastic paraparesis, and white-matter lesions (Marrosu et al., 2006). Memory impairment and personality changes characterized the onset of disease, which ranged between 32 and 45 years of age. In addition, motor impairments, including spastic paraparesis, emerged early on. All mutation carriers had an APOE 3/3 genotype. The mutation was absent from 96 patients with sporadic multiple sclerosis and 96 unrelated, healthy controls.. Neuropathology. Neuropathological data are unavailable. However, MRI scans from four individuals revealed disseminated white-matter lesions reminiscent of those found in multiple sclerosis (Marrosu et al., 2006). Areas of hyperintensity in the frontal and temporal lobes were similar to those seen in cerebral autosomal-dominant arteriopathy (CADASIL), but no subcortical lacunar lesions typical of CADASIL were observed.

Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leucoencephalopathy (CADASIL) is an archetypal small vessel disease of the brain caused by dominant mutations in the NOTCH3 receptor. Cardinal vascular lesions include deposition of granular osmiophilic material (GOM) within the basal lamina of smooth muscle cells, progressive smooth muscle cell loss, and fibrosis of the media. Pathogenic mutations alter the number of cysteine residues in the extracellular domain of NOTCH3 (Notch3 ECD), leading to its abnormal accumulation in the GOM deposits. Vascular smooth muscle cell has been identified as the primary target cell in this disease. Pathophysiological processes leading from NOTCH3 mutations to smooth muscle cell loss remain poorly understood.. The investigators propose to study these mechanisms by reprogramming skin cells to become stem cells and then differentiating them to vascular smooth muscle cells.. The hypothesis of this study is that the differentiated smooth muscle ...
The Notch protein is a transmembrane signaling protein responsible for regulating several important pathways among all metazoans including cell proliferation, differentiation, and death. Notch exists as one protein in Drosophila, but has four homologs in mice and humans (Notch1- 4). A defining component of the Notch protein is the presence of 29-36 tandem epidermal growth factor-like (EGF) repeats, small protein motifs defined by the presence of six cysteines forming three disulfide bonds. Defects in Notch have been linked to various diseases like Alagille syndrome and cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). CADASIL is responsible for early onset of dementia in patients aged 40-50, along with migraines and stroke. CADASIL is characterized by the presence and accumulation of granular osmiophilic material (GOMs) and Notch3 extracellular domain in close proximity to vascular smooth muscle cells, eventually leading to the degradation of ...
Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) represents the most common hereditary form of cerebral small vessel disease characterized by early-onset stroke and premature dementia. It is caused by mutations in the transmembrane receptor Notch3, which promote the aggregation and accumulation of the Notch3 extracellular domain (Notch3-ECD) within blood vessel walls. This process is believed to mediate the abnormal recruitment and dysregulation of additional factors including extracellular matrix (ECM) proteins resulting in brain vessel dysfunction. Based on recent evidence indicating a role for the transforming growth factor-β (TGF-β) pathway in sporadic and familial small vessel disease we studied fibronectin, fibrillin-1 and latent TGF-β binding protein 1 (LTBP-1), three ECM constituents involved in the regulation of TGF-β bioavailability, in post-mortem brain tissue from CADASIL patients and control subjects. Fibronectin and fibrillin-1 were

This is the first case report of a CADASIL patient with MCA stenosis who underwent STA-MCA bypass to increase cerebral perfusion in the localized ischemic area. In CADASIL, reductions in both CBF and CVR occur in white matter showing T2-hyperintensity. It has been suggested that the degeneration of vascular smooth muscle cells causes arteriopathy, which leads to cerebral hypoperfusion and impaired autoregulation (Chabriat et al. 2000; Huang et al. 2010; Singhal and Markus 2005; van den Boom et al. 2003). Interestingly, the white-matter hyperintensity in the temporal lobe was found predominant in the left side in this case. This asymmetry of white-matter hyperintensity is very unusual rare in CADASIL, since it would suggest that these lesions do not originate from ischemia, but edema instead. The lower extent observed in the most hypoperfused temporal lobe further support that these lesions are not related to ischemia but mat actually result from edema with blood brain barrier dysfunction. ...

sometimes referred to as white matter because of its white, fatty appearance, protects and insulates the axons. It consists of a protective sheath of many different molecules that include both lipids (fatty molecules) and proteins. This protective sheath acts in a manner very similar to that of the protective insulation that surrounds an electric wire; that is, it is necessary for the rapid transmission of electrical signals between neurons. It does this primarily by containing the electrical molecules (called ions) within the axon so that they are properly transmitted to the next neuron ...

The posterior spinal cord contains longer perforating arteries that might be more susceptible to the effects of CADASIL vasculopathy. This explains the clinical (predominantly dorsal column involvement and motor deficit) and imaging features compared with those in the more common anterior spinal cord infarction (predominantly spinothalamic tract involvement and motor deficit). The stepwise progression could be explained by sequential involvement of perforating spinal cord arteries. Her clinical improvement is likely attributable to the combination of corticosteroid-responsive peri-ischaemic inflammatory changes and natural recovery.. Spinal cord involvement in CADASIL is well recognised but rare. In a UK cohort of 200 patients, there were no cases of spinal cord infarction.1 An anterior spinal cord infarct occurred in an Irish patient with probable CADASIL who had a history of severe migrainous headaches.7 A cervical spinal cord MRI study showed no abnormalities in 25 symptomatic CADASIL ...

BACKGROUND AND PURPOSE: Reaction time was recently recognized as a marker of subtle cognitive and behavioral alterations in the early clinical stages of CADASIL, a monogenic cerebral small-vessel disease. In unselected patients with CADASIL, brain atrophy and lacunes are the main imaging correlates of disease severity, but MR imaging correlates of reaction time in mildly affected patients are unknown. We hypothesized that reaction time is independently associated with the corpus callosum area in the early clinical stages of CADASIL. ...

Microangiopathies may cause ischemic brain lesions and are of fundamental importance in vascular dementia. Risk factors include high age, hypertension, diabetes and Alzheimers disease. In addition, recent studies have focused on autosomal dominant types of arteriopathy causing leukoencephalopathy,psychiatric disturbances, stroke and dementia (CADASIL). This thesis concerns various collagens andbasal lamina components which are deposited in vascular walls of cases presenting cerebral microangiopathy. In addition, endothelin-like immunoreactivity has been studied in CADASIL cases andsome other brain diseases.. CADASIL cases described by Sourander and Wålinder (1977) were re-investigated. Those with longduration of the disease presented marked expression of fibrillary collagen types I, Ill, V and VI and of thebasal lamina components, collagen type IV and laminin. Deposits appeared also in non-familial casespresenting hyalinosis and in cases with the Binswanger type of leukoencephalopathy. Media ...
On-target drug delivery remains a challenge in cancer precision medicine; it is difficult to deliver a targeted therapy to cancer cells without incurring toxicity to normal tissues. The SERCA (sarco-endoplasmic reticulum Ca2+ ATPase) inhibitor thapsigargin inhibits mutant NOTCH1 receptors compared with wild type in T cell acute lymphoblastic leukemia (T-ALL), but its administration is predicted to be toxic in humans. Leveraging the addiction of ALL to folic acid, we conjugated folate to an alcohol derivative of thapsigargin via a cleavable ester linkage. JQ-FT is recognized by folate receptors on the plasma membrane and delivered into leukemia cells as a potent antileukemic agent. In mechanistic and translational models of T-ALL, we demonstrate NOTCH1 inhibition in vitro and in vivo. These proof-of-concept studies support the further optimization of this first-in-class NOTCH1 inhibitor with dual selectivity: leukemia over normal cells and NOTCH1 mutants over wild-type receptors. Furthermore, ...

Angiogenesis, a tightly regulated process of new blood vessel formation, is initiated when a select set of endothelial cells is stimulated to leave their quiescent state.1 These cells become hypermigratory and form sprouts that guide the direction of vascular network development.2 Formation of this ordered network depends on a regulated differentiation of the endothelial cells in which only specific endothelial cells can become sprouts. The consequence of dysregulation would be a failure to develop a cohesive vascular network. Examples of this can be seen in vascular diseases, such as CADASIL, and in tumor growth.3,4. Article, see p 1206. The vascular network forms when endothelial sprouts develop at the leading edge of the angiogenic front. These leading sprouts are known as the tip cells, characterized by filopodial expansions, which guide growth toward proangiogenic signals. Behind them are the stalk cells that provide a supporting network through proliferation and lumen formation. A critical ...
Vascular elasticity is crucial for maintaining hemodynamics. Molecular mechanisms involved in human elastogenesis are incompletely understood. We describe a syndrome of lethal arteriopathy associated with a novel,identical mutation in the fibulin 4 gene (FBLN4) in a unique cohort of infants from South India. Clinical characteristics, cardiovascular findings, outcomes and molecular genetics of twenty-two infants from a distinct population subgroup,presenting with characteristic arterial dilatation and tortuosity during the period August 2004 to June 2011 were studied. Patients (11 males, 11 females) presented at median age of 1.5 months,belonging to unrelated families from identical ethno-geographical background; eight had a history of consanguinity. Cardiovascular features included aneurysmal dilatation, elongation, tortuosity and narrowing of the aorta, pulmonary artery and their branches. The phenotype included a variable combination of cutis laxa (52%), long philtrum-thin vermillion (90%),
Differentiating spermatocytes have been examined in a diploid culture of Pteridium gametophytes. Spermatogenesis is similar to that in haploid antheridia. Although the nucleus of the diploid gamete is larger, no differences have been detected in the dimensions of components such as microtubules and flagella.. Microtubules scattered in the cytoplasm of the young spermatocytes follow an irregular course and show no particular relationship to the blepharoplast, even during the differentiation of its periphery into basal bodies with characteristic triplets. Subsequently short lengths of notably straighter microtubules appear in quantity adjacent to the osmiophilic material lying along the microtubular ribbon of the developing gamete. These microtubules are particularly frequent around the distal ends of flagella beginning to develop from basal bodies, and often appear to converge upon them.. The view is put forward that the osmiophilic material adjacent to the microtubular ribbon, ontogenetically ...
The High temperature requirement A (HtrA) proteases are a family of serine proteases conserved from bacteria to mammals, and are known to have important functions in protecting cells from stress conditions. There are four mammalian HtrA paralogs (HtrA1-4). HtrA1 is involved in apoptosis and anoikis, and is proposed to function as a tumour suppressor. It has also been implicated in the development of other diseases such as arthritis, Alzheimers disease, age-related macular degeneration, and cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy. We have previously shown that HtrA1 is highly enriched in the placenta compared to other tissues, and that in women HtrA1 is expressed in placental and endometrial cells at the placental-maternal interface during the first trimester of pregnancy. HtrA1 has recently been reported to be upregulated in preeclampsia (PE), a pregnancy-specific systemic disorder primarily involving hypertension and proteinuria, typically ...
About small vessel disease: Small vessel disease (acronym: SVD), a group of vascular disorders resulting from the pathological impairment of the small blood vessels of the brain, is strongly linked to causing some forms of dementia and stroke. These diseases have a huge social and economic impact. SVD is a global problem, but a treatment is yet to be discovered.
Most patients with small vessel disease are treated with long-term medications, such as medications that widen blood vessels or anti-clotting drugs, as well as medications that control blood pressure, cholesterol, or underlying medical conditions such as diabetes that increase the risk of small vessel disease.

Although various pathophysiologic mechanisms have been proposed to explain the development of CTEPH, questions remain as to why this condition only occurs in a minority of patients following an acute PE. Historically, two competing hypotheses were proposed. One early hypothesis was that local in situ thrombosis of smaller arteries resulted in a distal arteriopathy and subsequent PH.20 An important critique of this proposed mechanism is that it does not explain the proximal vascular occlusion commonly seen in CTEPH. The alternate hypothesis, therefore, is the thromboembolic theory: in this model, emboli from the systemic circulation become lodged within the pulmonary vasculature and fail to resolve. Various factors cause these emboli to progress and stabilize. A distal microvascular arteriopathy can develop subsequently due to elevated pulmonary pressures or from other effects triggered by the presence of these stabilized thrombotic lesions.3. A significant amount of knowledge regarding the ...
