Calcineurin
A CALCIUM and CALMODULIN-dependent serine/threonine protein phosphatase that is composed of the calcineurin A catalytic subunit and the calcineurin B regulatory subunit. Calcineurin has been shown to dephosphorylate a number of phosphoproteins including HISTONES; MYOSIN LIGHT CHAIN; and the regulatory subunits of CAMP-DEPENDENT PROTEIN KINASES. It is involved in the regulation of signal transduction and is the target of an important class of immunophilin-immunosuppressive drug complexes.
Tacrolimus
A macrolide isolated from the culture broth of a strain of Streptomyces tsukubaensis that has strong immunosuppressive activity in vivo and prevents the activation of T-lymphocytes in response to antigenic or mitogenic stimulation in vitro.
NFATC Transcription Factors
A family of transcription factors characterized by the presence of highly conserved calcineurin- and DNA-binding domains. NFAT proteins are activated in the CYTOPLASM by the calcium-dependent phosphatase CALCINEURIN. They transduce calcium signals to the nucleus where they can interact with TRANSCRIPTION FACTOR AP-1 or NF-KAPPA B and initiate GENETIC TRANSCRIPTION of GENES involved in CELL DIFFERENTIATION and development. NFAT proteins stimulate T-CELL activation through the induction of IMMEDIATE-EARLY GENES such as INTERLEUKIN-2.
Cyclosporine
A cyclic undecapeptide from an extract of soil fungi. It is a powerful immunosupressant with a specific action on T-lymphocytes. It is used for the prophylaxis of graft rejection in organ and tissue transplantation. (From Martindale, The Extra Pharmacopoeia, 30th ed).
Calmodulin-Binding Proteins
Proteins which bind calmodulin. They are found in many tissues and have a variety of functions including F-actin cross-linking properties, inhibition of cyclic nucleotide phosphodiesterase and calcium and magnesium ATPases.
Immunosuppressive Agents
Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging.
Phosphoprotein Phosphatases
A group of enzymes removing the SERINE- or THREONINE-bound phosphate groups from a wide range of phosphoproteins, including a number of enzymes which have been phosphorylated under the action of a kinase. (Enzyme Nomenclature, 1992)
Tacrolimus Binding Proteins
A family of immunophilin proteins that bind to the immunosuppressive drugs TACROLIMUS (also known as FK506) and SIROLIMUS. EC 5.2.1.-
Calcium
A basic element found in nearly all organized tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.
Signal Transduction
The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.
Calmodulin
A heat-stable, low-molecular-weight activator protein found mainly in the brain and heart. The binding of calcium ions to this protein allows this protein to bind to cyclic nucleotide phosphodiesterases and to adenyl cyclase with subsequent activation. Thereby this protein modulates cyclic AMP and cyclic GMP levels.
Tacrolimus Binding Protein 1A
A 12-KDa tacrolimus binding protein that is found associated with and may modulate the function of calcium release channels. It is a peptidyl-prolyl cis/trans isomerase which is inhibited by both tacrolimus (commonly called FK506) and SIROLIMUS.
Cardiomegaly
Enlargement of the HEART, usually indicated by a cardiothoracic ratio above 0.50. Heart enlargement may involve the right, the left, or both HEART VENTRICLES or HEART ATRIA. Cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (HEART FAILURE) or several forms of CARDIOMYOPATHIES.
Amino Acid Isomerases
Enzymes that catalyze either the racemization or epimerization of chiral centers within amino acids or derivatives. EC 5.1.1.
Sirolimus
A macrolide compound obtained from Streptomyces hygroscopicus that acts by selectively blocking the transcriptional activation of cytokines thereby inhibiting cytokine production. It is bioactive only when bound to IMMUNOPHILINS. Sirolimus is a potent immunosuppressant and possesses both antifungal and antineoplastic properties.
Phosphoric Monoester Hydrolases
A group of hydrolases which catalyze the hydrolysis of monophosphoric esters with the production of one mole of orthophosphate. EC 3.1.3.
Calcium Signaling
Signal transduction mechanisms whereby calcium mobilization (from outside the cell or from intracellular storage pools) to the cytoplasm is triggered by external stimuli. Calcium signals are often seen to propagate as waves, oscillations, spikes, sparks, or puffs. The calcium acts as an intracellular messenger by activating calcium-responsive proteins.
Immunophilins
Members of a family of highly conserved proteins which are all cis-trans peptidyl-prolyl isomerases (PEPTIDYLPROLYL ISOMERASE). They bind the immunosuppressant drugs CYCLOSPORINE; TACROLIMUS and SIROLIMUS. They possess rotamase activity, which is inhibited by the immunosuppressant drugs that bind to them.
Kidney Transplantation
The transference of a kidney from one human or animal to another.
Transcription Factors
Endogenous substances, usually proteins, which are effective in the initiation, stimulation, or termination of the genetic transcription process.
Phosphorylation
The introduction of a phosphoryl group into a compound through the formation of an ester bond between the compound and a phosphorus moiety.
Cells, Cultured
Cells propagated in vitro in special media conducive to their growth. Cultured cells are used to study developmental, morphologic, metabolic, physiologic, and genetic processes, among others.
Peptidylprolyl Isomerase
An enzyme that catalyzes the isomerization of proline residues within proteins. EC 5.2.1.8.
Muscle Proteins
The protein constituents of muscle, the major ones being ACTINS and MYOSINS. More than a dozen accessory proteins exist including TROPONIN; TROPOMYOSIN; and DYSTROPHIN.
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction.
Molecular Sequence Data
Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.

Proteins which bind to DNA. The family includes proteins which bind to both double- and single-stranded DNA and also includes specific DNA binding proteins in serum which can be used as markers for malignant diseases.
Amino Acid Sequence
The order of amino acids as they occur in a polypeptide chain. This is referred to as the primary structure of proteins. It is of fundamental importance in determining PROTEIN CONFORMATION.
Mycophenolic Acid
An antibiotic substance derived from Penicillium stoloniferum, and related species. It blocks de novo biosynthesis of purine nucleotides by inhibition of the enzyme inosine monophosphate dehydrogenase. Mycophenolic acid is important because of its selective effects on the immune system. It prevents the proliferation of T-cells, lymphocytes, and the formation of antibodies from B-cells. It also may inhibit recruitment of leukocytes to inflammatory sites. (From Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 9th ed, p1301)
Nuclear Proteins
Proteins found in the nucleus of a cell. Do not confuse with NUCLEOPROTEINS which are proteins conjugated with nucleic acids, that are not necessarily present in the nucleus.

Protein Phosphatase 2
A phosphoprotein phosphatase subtype that is comprised of a catalytic subunit and two different regulatory subunits. At least two genes encode isoforms of the protein phosphatase catalytic subunit, while several isoforms of regulatory subunits exist due to the presence of multiple genes and the alternative splicing of their mRNAs.

A eukayrotic protein serine-threonine phosphatase subtype that dephosphorylates a wide variety of cellular proteins. The enzyme is comprised of a catalytic subunit and regulatory subunit. Several isoforms of the protein phosphatase catalytic subunit exist due to the presence of multiple genes and the alternative splicing of their mRNAs. A large number of proteins have been shown to act as regulatory subunits for this enzyme. Many of the regulatory subunits have additional cellular functions.

The role of immunophilins in mutant superoxide dismutase-1linked familial amyotrophic lateral sclerosis. (1/2213)

It has been reported that expression of familial amyotrophic lateral sclerosis (FALS)-associated mutant Cu/Zn superoxide dismutase-1 (SOD) induces apoptosis of neuronal cells in culture associated with an increase in reactive oxygen species. SOD recently has been shown to prevent calcineurin inactivation, initiating the present investigations examining the role of calcineurin in mutant SOD-induced cell death. Wild-type or mutant SOD was expressed in neuronal cells by infection with replication-deficient adenoviruses. PC12 cells overexpressing human wild-type SOD exhibited higher calcineurin activity than cells expressing FALS-related mutant SOD (SODV148G); however, cells expressing SODV148G had calcineurin activity equal to mock-infected cells, suggesting that cell death induced by mutant SOD was not related to a decrease in calcineurin activity. Calcineurin antagonists such as cyclosporin A and FK506, as well as nonimmunosuppressant analogs of cyclosporin A, significantly enhanced SODV148G- and SODA4V-induced cell death. Because both groups of drugs inhibit the rotamase activity of cyclophilins (CyP), but only the immunosuppressant analogs inhibit calcineurin activity, these data suggest that rotamase inhibition underlies the enhanced cell death after SODV148G expression. The importance of rotamase activity in mutant SOD-mediated apoptosis was supported by experiments showing that overexpressed wild-type cyclophilin A (CyPA), but not CyPA with a rotamase active site point mutation, protected cells from death after SODV148G expression. These data suggest that mutant SOD produces a greater need for rotamase and, also, highlights possible new therapeutic strategies in FALS.  (+info)

Differential effects of a calcineurin inhibitor on glutamate-induced phosphorylation of Ca2+/calmodulin-dependent protein kinases in cultured rat hippocampal neurons. (2/2213)

Calcium/calmodulin-dependent protein kinases (CaM kinases) are major multifunctional enzymes that play important roles in calcium-mediated signal transduction. To characterize their regulatory mechanisms in neurons, we compared glutamate-induced phosphorylation of CaM kinase IV and CaM kinase II in cultured rat hippocampal neurons. We observed that dephosphorylation of these kinases followed different time courses, suggesting different regulatory mechanisms for each kinase. Okadaic acid, an inhibitor of protein phosphatase (PP) 1 and PP2A, increased the phosphorylation of both kinases. In contrast, cyclosporin A, an inhibitor of calcineurin, showed different effects: the phosphorylation and activity of CaM kinase IV were significantly increased with this inhibitor, but those of CaM kinase II were not significantly increased. Cyclosporin A treatment of neurons increased phosphorylation of Thr196 of CaM kinase IV, the activated form with CaM kinase kinase, which was recognized with an anti-phospho-Thr196 antibody. Moreover, recombinant CaM kinase IV was dephosphorylated and inactivated with calcineurin as well as with PP1, PP2A, and PP2C in vitro. These results suggest that CaM kinase IV, but not CaM kinase II, is directly regulated with calcineurin.  (+info)

Reduction of calcineurin activity in brain by antisense oligonucleotides leads to persistent phosphorylation of tau protein at Thr181 and Thr231. (3/2213)

Phosphorylation of tau protein promotes stability of the axonal cytoskeleton; aberrant tau phosphorylation is implicated in the biogenesis of paired helical filaments (PHF) seen in Alzheimer's disease. Protein kinases and phosphatases that modulate tau phosphorylation have been identified using in vitro techniques; however, the role of these enzymes in vivo has not been determined. We used intraventricular infusions of antisense oligodeoxynucleotides (ODNs) directed against the major brain isoforms of the Ca2+/calmodulin-dependent phosphatase calcineurin to determine how reduced activity of this enzyme would affect tau dephosphorylation. Five-day infusions of antisense ODNs (5 and 10 nmol/day) in rats decreased immunoreactive levels and activity of calcineurin throughout the brain; sense ODNs, scrambled ODNs, and infusion vehicle alone had no effect. When neocortical slices were prepared from antisense ODN-treated rats and incubated for 1 to 2 h in vitro, tau protein remained phosphorylated as determined by using the phosphorylation-sensitive monoclonal antibodies AT-180 (Thr231) and AT-270 (Thr181). In contrast, AT-180 and AT-270 sites were completely dephosphorylated during incubation of neocortical slices from vehicle-infused controls and sense ODN-treated rats. Neocortical slices from antisense-treated rats were incubated with the phosphatase inhibitors okadaic acid (100 nM; 10 microM) and FK-520 (5 microM); these preparations showed enhanced tau phosphorylation, consistent with a significant loss of calcineurin activity. Thus, we conclude that phosphorylation of at least two sites on tau protein, namely, Thr181 and Thr231, is regulated by calcineurin.  (+info)

Failure of calcineurin inhibitors to prevent pressure-overload left ventricular hypertrophy in rats. (4/2213)

A rapidly emerging body of literature implicates a pivotal role for the Ca2+-calmodulin-dependent phosphatase calcineurin as a cellular target for a variety of Ca2+-dependent signaling pathways culminating in left ventricular hypertrophy (LVH). Most of the recent experimental support for this hypothesis is derived from in vitro studies or in vivo studies in transgenic mice expressing activated calcineurin or mutant sarcomeric proteins. The aim of the present study was to test whether calcineurin inhibitors, cyclosporin A (CsA) and FK 506, prevent pressure-overload LVH using 2 standard rat models: (1) the spontaneously hypertensive rat (SHR) and (2) aortic banding. The major new findings are 2-fold. First, in SHR, LVH (left ventricular weight to body weight ratio) was unaffected by a dose of CsA (5 mg. kg-1. d-1) that was sufficient to raise blood pressure and to inhibit calcineurin-mediated transcriptional activation in skeletal muscle. Second, in rats with aortic banding, LVH was unaffected by FK 506 (0.3 mg. kg-1. d-1) or even higher doses of CsA (10 and 20 mg. kg-1. d-1) that were sufficient to inhibit 90% of total calcineurin phosphatase activity in the hypertrophied myocardium. In the latter experiments, CsA blocked neither the elevated left ventricular end-diastolic pressures, a measure of diastolic function, nor the induction in atrial natriuretic peptide mRNA in the hypertrophic ventricles. Thus, in numerous experiments, systemic administration of potent calcineurin inhibitors did not prevent the development of LVH in 2 classic models of pressure-overload hypertrophy. These results demonstrate that pressure-overload hypertrophy can arise through calcineurin-independent pathways.  (+info)

Pressure overload induces severe hypertrophy in mice treated with cyclosporine, an inhibitor of calcineurin. (5/2213)

Cardiac hypertrophy is the fundamental adaptation of the adult heart to mechanical load. Recent work has shown that inhibition of calcineurin activity with cyclosporine suppresses the development of hypertrophy in calcineurin transgenic mice and in in vitro systems of neonatal rat cardiocytes stimulated with peptide growth factors. To test the hypothesis that the calcineurin signaling pathway is critical for load-induced hypertrophy in vivo, we examined the effects of cyclosporine treatment on left ventricular hypertrophy induced by experimental ascending aortic stenosis for 4 weeks in mice. Left ventricular systolic pressure was elevated to a similar level in aortic stenosis mice that were treated with cyclosporine versus no drug. Left ventricular mass and myocyte size were similar in treated and untreated aortic stenosis animals and significantly greater than control animals, showing that cyclosporine treatment does not suppress hypertrophic growth. Both treated and untreated animals showed increased left ventricular expression of the load-sensitive gene atrial natriuretic factor. Calcineurin activity was measured in the left ventricle and the spleen from control mice and aortic stenosis mice treated with cyclosporine versus no drug. Levels of calcineurin activity were similar in the spleens of control and untreated aortic stenosis mice. However, calcineurin activity was severely depressed in left ventricular tissue of untreated aortic stenosis mice compared with control mice and was further reduced by cyclosporine treatment. Thus, pathological hypertrophy and cardiac-restricted gene expression induced by pressure overload in vivo are not suppressed by treatment with cyclosporine and do not appear to depend on the elevation of left ventricular calcineurin activity.  (+info)

Ca2+-induced apoptosis through calcineurin dephosphorylation of BAD. (6/2213)

The Ca2+-activated protein phosphatase calcineurin induces apoptosis, but the mechanism is unknown. Calcineurin was found to dephosphorylate BAD, a pro-apoptotic member of the Bcl-2 family, thus enhancing BAD heterodimerization with Bcl-xL and promoting apoptosis. The Ca2+-induced dephosphorylation of BAD correlated with its dissociation from 14-3-3 in the cytosol and translocation to mitochondria where Bcl-xL resides. In hippocampal neurons, L-glutamate, an inducer of Ca2+ influx and calcineurin activation, triggered mitochondrial targeting of BAD and apoptosis, which were both suppressible by coexpression of a dominant-inhibitory mutant of calcineurin or pharmacological inhibitors of this phosphatase. Thus, a Ca2+-inducible mechanism for apoptosis induction operates by regulating BAD phosphorylation and localization in cells.  (+info)

Yeast calcineurin regulates nuclear localization of the Crz1p transcription factor through dephosphorylation. (7/2213)

Calcineurin, a Ca2+/calmodulin dependent protein phosphatase, regulates Ca2+-dependent processes in a wide variety of cells. In the yeast, Saccharomyces cerevisiae, calcineurin effects Ca2+-dependent changes in gene expression through regulation of the Crz1p transcription factor. We show here that calcineurin dephosphorylates Crz1p and that this results in translocation of Crz1p to the nucleus. We identify a region of Crz1p that is required for calcineurin-dependent regulation of its phosphorylation, localization, and activity, and show that this region has significant sequence simlarity to a portion of NF-AT, a family of mammalian transcription factors whose localization is also regulated by calcineurin. Thus, the mechanism of Ca2+/calcineurin-dependent signaling shows remarkable conservation between yeast and mammalian cells.  (+info)

A selective role of calcineurin aalpha in synaptic depotentiation in hippocampus. (8/2213)

Pharmacological studies have suggested that long-term potentiation (LTP) and long-term depression (LTD) and depotentiation, three forms of synaptic plasticity in the hippocampus, require the activity of the phosphatase calcineurin. At least two different isoforms of calcineurin are found in the central nervous system. To investigate whether all of these forms of synaptic plasticity require the same isoforms of calcineurin, we have examined LTD, depotentiation, and LTP in mice lacking the predominant calcineurin isoform in the central nervous system, Aalpha-/- mice. Depotentiation was abolished completely whereas neither LTD nor LTP were affected. These studies provide genetic evidence that the Aalpha isoform of calcineurin is important for the reversal of LTP in the hippocampus and indicate that depotentiation and LTD operate through somewhat different molecular mechanisms.  (+info)

The role of modulatory calcineurin-interacting proteins in calcineurin signaling. - Semantic ScholarThe role of modulatory calcineurin-interacting proteins in calcineurin signaling. - Semantic Scholar
Modulatory calcineurin-interacting proteins (MCIPs), also known as the Down syndrome critical region 1 (DSCR1) and DSCR1-like proteins, are a recently described family of small, structurally related proteins that are preferentially expressed in heart, skeletal muscle, and brain. MCIP proteins can bind to and inhibit calcineurin, a calcium/calmodulin-regulated serine/threonine protein phosphatase that is activated during cardiac hypertrophy and failure. Transcription of the mammalian MCIP1 gene is induced by calcineurin, suggesting that it functions as an endogenous feedback regulator of calcineurin signal transduction. Forced expression of human MCIP1 protein in the hearts of transgenic mice attenuates the hypertrophic response to a broad range of stimuli. This review summarizes work from a number of laboratories on the structure, regulation, and function of MCIP proteins.

Background: Activation of the protein phosphatase calcineurin is a fundamental signaling event promoting hypertrophic growth and pathological remodeling of the heart. The modulatory calcineurin-interacting protein 1 (MCIP1) is an endogenous feedback inhibitor of calcineurin. We have previously shown that increasing the level of MCIP1 protein protects the heart from unrestrained activation of calcineurin, suggesting that strategies to increase MCIP1 protein in the heart may be a viable therapeutic approach. To this end we have undertaken genetic and biochemical studies to decipher mechanisms that regulate degradation of MCIP1 proteins.. Methods and Results: There are two major isoforms of MCIP1 (MCIP1.1 and MCIP1.4). MCIP1.1 levels are extremely stable with a half-life of over 8 hours in cultured cardiomyocytes. In contrast, MCIP1.4 levels are very low in an unstressed heart but increase precipitously in response to stress and calcineurin activation. Unlike MCIP1.1, the MCIP1.4 protein is ...

The PMC1 gene in Saccharomyces cerevisiae encodes a vacuolar Ca2+ ATPase required for growth in high-Ca2+ conditions. Previous work showed that Ca2+ tolerance can be restored to pmc1 mutants by inactivation of calcineurin, a Ca2+/calmodulin-dependent protein phosphatase sensitive to the immunosuppressive drug FK506. We now report that calcineurin decreases Ca2+ tolerance of pmc1 mutants by inhibiting the function of VCX1, which encodes a vacuolar H+/Ca2+ exchanger related to vertebrate Na+/Ca2+ exchangers. The contribution of VCX1 in Ca2+ tolerance is low in strains with a functional calcineurin and is high in strains which lack calcineurin activity. In contrast, the contribution of PMC1 to Ca2+ tolerance is augmented by calcineurin activation. Consistent with these positive and negative roles of calcineurin, expression of a vcx1::lacZ reporter was slightly diminished and a pmc1::lacZ reporter was induced up to 500-fold by processes dependent on calcineurin, calmodulin, and Ca2+.

Calcineurin - WikipediaCalcineurin - Wikipedia
Calcineurin (CaN) is a calcium and calmodulin dependent serine/threonine protein phosphatase (also known as protein phosphatase 3, and calcium-dependent serine-threonine phosphatase). It activates the T cells of the immune system and can be blocked by drugs. Calcineurin activates nuclear factor of activated T cell, cytoplasmic (NFATc), a transcription factor, by dephosphorylating it. The activated NFATc is then translocated into the nucleus, where it upregulates the expression of interleukin 2 (IL-2), which, in turn, stimulates the growth and differentiation of T cell response. Calcineurin is the target of a class of drugs called calcineurin inhibitors, which includes cyclosporin, voclosporin, pimecrolimus and tacrolimus. Calcineurin is a heterodimer of a 61-kD calmodulin-binding catalytic subunit, calcineurin A and a 19-kD Ca2+-binding regulatory subunit, calcineurin B. There are three isozymes of the catalytic subunit, each encoded by a separate gene (PPP3CA, PPP3CB, and PPP3CC) and two ...

Calcineurin is required for virulence of Cryptococcus neoformans | The EMBO JournalCalcineurin is required for virulence of Cryptococcus neoformans | The EMBO Journal
A less likely alternative hypothesis is that calcineurin is not part of a signal transduction pathway required for virulence, but is instead required to maintain activity of components required for growth at high temperature and CO2 and pH resistance. Such a model would require that some proteins differ in phosphorylation state at 37 and 24°C, or that activity at 37°C requires dephosphorylation whereas activity at 24°C does not. One means to test these and other models, and to identify downstream effectors of calcineurin, would be to characterize suppressor mutations that restore growth to calcineurin mutants at 37°C. In summary, our studies reveal that calcineurin is required for virulence and may delineate the first elements of a signal transduction cascade required for fungal pathogenesis.. By analogy with other systems, the targets of calcineurin might include ion pumps or transcription factors, which could regulate expression of other proteins required for virulence. The role of ...

Galactokinase is a Novel Modifier of Calcineurin-Induced Cardiomyopathy in DrosophilaGalactokinase is a Novel Modifier of Calcineurin-Induced Cardiomyopathy in Drosophila
Calcineurin is both necessary and sufficient to induce cardiac hypertrophy, an independent risk factor for arrhythmia, dilated cardiomyopathy, heart failure, and sudden cardiac death. However, current knowledge of the downstream effectors of calcineurin is limited.

Sotrastaurin, a novel selective protein-kinase-C inhibitor, inhibits early T cell activation via a calcineurin-independent pathway. Efficacy and safety of sotrastaurin in a calcineurin inhibitor-free regimen were evaluated in this two-stage Phase II study of de novo kidney transplant recipients. Stage 1 randomized 131 patients (2:1) to sotrastaurin 300 mg or cyclosporine A (CsA). Stage 2 randomized 180 patients (1:1:1) to sotrastaurin 300 or 200 mg or CsA. All patients received basiliximab, everolimus (EVR) and prednisone. Primary endpoint was composite efficacy failure rate of treated biopsy-proven acute rejection, graft loss, death or lost to follow-up. Main safety assessment was estimated glomerular filtration rate (eGFR) by MDRD-4 at Month 12. Composite efficacy failure rates at 12 months were higher in sotrastaurin arms (Stage 1: 16.5% and 10.9% for sotrastaurin 300 mg and CsA; Stage 2: 27.2%, 34.5% and 19.4% for sotrastaurin 200 mg, 300 mg and CsA). eGFR was significantly better in ...

Identification of Calcineurin as a Key Signal in the Extinction of Fear Memory | Journal of NeuroscienceIdentification of Calcineurin as a Key Signal in the Extinction of Fear Memory | Journal of Neuroscience
After been conditioned, rats were divided into two groups: light-alone and context control. Immunoblotting for phosphorylated Akt (P-Akt) was performed immediately after extinction training (Fig. 2C). Figure 2D indicates that the degree of Akt phosphorylation was significantly reduced in the light-alone group (t(10) = 3.75;p , 0.01). In contrast, Akt phosphorylation in the context control group was comparable with and not significantly different from the preextinction test (t(10) = 0.32; p = 0.75). These results suggest that memory testing-induced Akt phosphorylation was abrogated after light-alone trials. Given that synaptic plasticity may be governed by the balance between protein kinase and phosphatase activity (ODell and Kandel, 1994; Winder and Sweatt, 2001), a decrease in the phosphorylated state of Akt after extinction trials led us consider the possible involvement of calcium-dependent phosphatase calcineurin. We determined the involvement of calcineurin by infusing FK-506, a ...

The goal of these experiments was to measure the activity of calcineurin in the PBMC of patients with SLE. The major results are as follows. Firstly, there is no difference in the calcineurin activities of PBMC in the GCS-free patients with SLE and healthy control subjects. Secondly, as far as we know, this is the first experimental evidence of decreased calcineurin activity of PBMC induced by GCS used for the treatment of patients with SLE.. Unfractionated PBMC-that is, suspensions of T and B lymphocytes, NK cells, and monocytes, were used in this study because the calcineurin activity assays required a large number of cells. As patients with SLE are lymphopenic it would have been difficult to obtain a sufficient volume of blood for the separation of various purified subsets of the cells. As the subsets of PBMC were characterised by flow cytometry, and as it was found that 69.4% of the cells were T cells, these preparations could be regarded as T cell-rich suspensions. There was no ...

Novel inhibitors of the calcineurin/NFATc hub - alternatives to CsA and FK506? | Cell Communication and Signaling | Full TextNovel inhibitors of the calcineurin/NFATc hub - alternatives to CsA and FK506? | Cell Communication and Signaling | Full Text
AID fragments, derived from the autoinhibitory domain of the calcineurin A subunit were the first examined inhibitory peptides for calcineurin. These peptides, containing the residues 424-521 (AID 424-521 ), are potent inhibitors of the phosphatase activity by blocking the access of protein substrates to the catalytic centre of calcineurin [164]. A peptide spanning the residues 457-482 (AID 457-482 ) of calcineurin represents the core inhibitory motif [165, 166]. This peptide is already able to suppress the dephosphorylation of the RII phosphopeptide in phosphatase assays. However, additional autoinhibitory elements are present within the calcineurin region 420-457. Therefore, the peptides containing the extended AID region AID420-511 and AID328-511 were three- to fourfold more potent to inhibit RII phosphopeptide dephosphorylation compared to the AID457-482 peptide [167]. The 11R-AID457-482 peptide, containing eleven arginine residues, is reported to be indeed cell-permeable for selected cell ...

JCI - Calcineurin inhibitors suppress acute graft-vs-host disease via NFAT-independent inhibition of T cell receptor signalingJCI - Calcineurin inhibitors suppress acute graft-vs-host disease via NFAT-independent inhibition of T cell receptor signaling
Inhibitors of calcineurin phosphatase activity (CNIs) such as cyclosporin A (CsA) are widely used to treat tissue transplant rejection and acute graft-versus-host disease (aGVHD), for which inhibition of NFAT-dependent gene expression is the mechanistic paradigm. We recently reported that CNIs inhibit TCR-proximal signaling by preventing calcineurin-mediated dephosphorylation of LckS59, an inhibitory modification, raising the possibility of another mechanism by which CNIs suppress immune responses. Here we utilized T cells from mice that express LckS59A, which cannot accept a phosphate at residue 59, to initiate aGVHD. Although CsA inhibited NFAT-dependent gene upregulation in allo-aggressive T cells expressing either LckWT or LckS59A, it was ineffective in treating disease when the T cells expressed LckS59A. Two important NFAT-independent T cell functions were found to be CsA-resistant in LckS59A T cells: upregulation of the cytolytic protein perforin in tissue-infiltrating CD8+ T cells and ...

A Role for Calcineurin Dysfunction in Schizophrenia? | Science SignalingA Role for Calcineurin Dysfunction in Schizophrenia? | Science Signaling
Schizophrenia, a form of mental illness that affects about 1% of the population, is believed to depend on a complex and incompletely understood interplay of genetic and environmental factors. Two related articles provide evidence suggesting that alterations in signaling from the serine-threonine phosphatase calcineurin may contribute to the pathogenesis of this severe and disabling disease. Miyakawa et al. subjected a strain of mutant mice that lacked forebrain calcineurin to a battery of tests and observed a spectrum of behavioral abnormalities reminiscent of those found in individuals with schizophrenia. The authors, who had previously noted deficits in working memory in these mice, observed decreased social interaction, impaired attention, and impaired nesting behavior. The mice also displayed increased hyperactivity, which is characteristic of other animal models of schizophrenia, and enhanced susceptibility to N-methyl-D-aspartate receptor blockade. In an accompanying article, Gerber et al. ...

In this study, we used whole-genome array analysis and pharmacological reagents to identify PROCR as a potential Cn/NFAT-dependent gene in vascular smooth muscle. We corroborate the only report to date that vascular SMCs do express the protein C receptor (PROCR).15 More importantly, we validate our informatics approach and are the first to report Cn/NFAT signaling as a regulator of PROCR activation. We show PDGF-BB stimulation induced PROCR expression in a Cn/NFAT-dependent manner at both the transcriptional and translational levels. Mutation of a highly conserved NFAT binding motif significantly attenuated PROCR promoter activation, supporting the NFAT-dependent property of PROCR activity. In addition, PROCR expression is upregulated in vivo as a result of acute vascular injury, highlighting the potential role of PROCR in vessel restenosis.. Until the recent detection of PROCR in vascular SMCs, PROCR was believed to be expressed predominantly in ECs. Studies to date on PROCR transcription focus ...

Calcineurin imposes T cell unresponsiveness through targeted proteolysis of signaling proteins. - The Kennedy Institute of...
Sustained calcium signaling induces a state of anergy or antigen unresponsiveness in T cells, mediated through calcineurin and the transcription factor NFAT. We show here that Ca(2+)-induced anergy is a multistep program that is implemented at least partly through proteolytic degradation of specific signaling proteins. Calcineurin increased mRNA and protein of the E3 ubiquitin ligases Itch, Cbl-b and GRAIL and induced expression of Tsg101, the ubiquitin-binding component of the ESCRT-1 endosomal sorting complex. Subsequent stimulation or homotypic cell adhesion promoted membrane translocation of Itch and the related protein Nedd4, resulting in degradation of two key signaling proteins, PKC-theta and PLC-gamma1. T cells from Itch- and Cbl-b-deficient mice were resistant to anergy induction. Anergic T cells showed impaired calcium mobilization after TCR triggering and were unable to maintain a mature immunological synapse, instead showing late disorganization of the outer ring containing lymphocyte

CDK5 and Calcineurin Regulate Synaptic Ca2+ Influx. Sung Hyun Kim and Timothy A. Ryan. (see pages 8937-8950). The cyclin-dependent kinase CDK5 has numerous targets and helps regulate nearly every aspect of neuron development and function, including migration, neurite outgrowth, synaptic vesicle release and recycling, synaptic plasticity, and neuron death. At synaptic terminals, CDK5 and the Ca2+-dependent phosphatase calcineurin work in opposition to regulate the distribution of synaptic vesicles between resting and recycling pools, thus regulating release during sustained activity. Kim and Ryan report that these molecules also regulate release probability in response to single action potentials by modulating influx through N-type voltage gated Ca2+ channels (CaV2.2) in rat hippocampal neurons. Specifically, knocking down the α isoform of calcineurin subunit A (CANα) reduced, whereas knocking down CDK5 increased Ca2+ influx and exocytosis evoked by single spikes. Blocking CaV2.2 occluded the ...

Calcineurin/NFAT Coupling Participates in Pathological, but not Physiological, Cardiac Hypertrophy | Circulation ResearchCalcineurin/NFAT Coupling Participates in Pathological, but not Physiological, Cardiac Hypertrophy | Circulation Research
In most models of pathological hypertrophy studied to date, inhibition of calcineurin-NFAT signaling has yielded either a reduction in the hypertrophic response and/or a delay in the progression from hypertrophy to heart failure.9,38 The data presented in this study extend this paradigm to demonstrate that calcineurin-NFAT signaling is activated in a sustained manner during both TAC-induced pressure overload and myocardial infarction-induced heart failure. However, very little is presently known regarding the role of calcineurin-NFAT signaling in regulating physiological hypertrophy or adaptive growth of the myocardium. Our results indicate that calcineurin-NFAT is not activated after either voluntary wheel-running or swimming, despite the observation of significant cardiac hypertrophy. In fact, swimming exercise even produced a significant and reproducible reduction in NFAT-luciferase activity in the heart at certain time points. Also of note, direct infusion of GH-IGF-1, which is thought to ...

Sustained hemodynamic stress, e.g. due to hypertension or valvular defects, ultimately results in pathological remodeling of the myocardium, characterized by hypertrophy, fibrosis and progressive contractile dysfunction. The phosphatase calcineurin plays a key role in the molecular pathogenesis of these processes. In previous experiments, we could show the mice deficient for the calcineurin-interacting protein calsarcin-1 (CS1) were sensitized to cardiomyopathic stimuli. Conversely, transgenic mice with a cardiac restricted overexpression of CS1 were protected against prohypertophic stimuli. To further explore the therapeutic potential of calsarcin-1, we now generated an adeno-associated virus serotype 9 (CS1-AAV9) expressing CS1 under the control of a cardiac-specific MLC2-CMV promoter. CS1-AAV9 or a control AAV9 encoding for luciferase (Luc-AAV9) were systemically injected into adult male C57Bl/6 mice (2x1011 genomes/mouse). After one week, osmotic minipumps were implanted for another two ...

gene. Loss of α-actinin-3 is associated with reduced power and enhanced endurance capacity in elite athletes and nonathletes due to slowing of the metabolic and physiological properties of fast fibers. Here, we have shown that α-actinin-3 deficiency results in increased calcineurin activity in mouse and human skeletal muscle and enhanced adaptive response to endurance training. α-Actinin-2, which is differentially expressed in α-actinin-3-deficient muscle, has higher binding affinity for calsarcin-2, a key inhibitor of calcineurin activation. We have further demonstrated that α-actinin-2 competes with calcineurin for binding to calsarcin-2, resulting in enhanced calcineurin signaling and reprogramming of the metabolic phenotype of fast muscle fibers. Our data provide a mechanistic explanation for the effects of the ...

Exposure of the yeast Saccharomyces cerevisiae to alkaline stress resulted in adaptive changes that involved remodeling the gene expression. Recent evidence suggested that the calcium-activated protein phosphatase calcineurin could play a role in alkaline stress signaling. By using an aequorin luminescence reporter, we showed that alkaline stress resulted in a sharp and transient rise in cytoplasmic calcium. This increase was largely abolished by addition of EGTA to the medium or in cells lacking Mid1 or Cch1, components of the high affinity cell membrane calcium channel. Under these circumstances, the alkaline response of different calcineurin-sensitive transcriptional promoters was also blocked. Therefore, exposure to alkali resulted in entry of calcium from the external medium, and this triggered a calcineurin-mediated response. The involvement of calcineurin and Crz1/Tcn1, the transcription factor activated by the phosphatase, in the transcriptional response triggered by alkalinization has ...

Genomic expression programs and the integration of the CD28 costimulatory signal in T cell activation. | Lewis-Sigler InstituteGenomic expression programs and the integration of the CD28 costimulatory signal in T cell activation. | Lewis-Sigler Institute
Optimal activation of T cells requires effective occupancy of both the antigen-specific T cell receptor and a second coreceptor such as CD28. We used cDNA microarrays to characterize the genomic expression program in human peripheral T cells responding to stimulation of these receptors. We found that CD28 agonists alone elicited few, but reproducible, changes in gene expression, whereas CD3 agonists elicited a multifaceted temporally choreographed gene expression program. The principal effect of simultaneous engagement of CD28 was to increase the amplitude of the CD3 transcriptional response. The induced genes whose expression was most enhanced by costimulation were significantly enriched for known targets of nuclear factor of activated T cells (NFAT) transcription factors. This enhancement was nearly abolished by blocking the nuclear translocation of NFATc by using the calcineurin inhibitor FK506. CD28 signaling promoted phosphorylation, and thus inactivation, of the NFAT nuclear export kinase ...

JCI - Age-dependent human β cell proliferation induced by glucagon-like peptide 1 and calcineurin signalingJCI - Age-dependent human β cell proliferation induced by glucagon-like peptide 1 and calcineurin signaling
Inadequate pancreatic β cell function underlies type 1 and type 2 diabetes mellitus. Strategies to expand functional cells have focused on discovering and controlling mechanisms that limit the proliferation of human β cells. Here, we developed an engraftment strategy to examine age-associated human islet cell replication competence and reveal mechanisms underlying age-dependent decline of β cell proliferation in human islets. We found that exendin-4 (Ex-4), an agonist of the glucagon-like peptide 1 receptor (GLP-1R), stimulates human β cell proliferation in juvenile but not adult islets. This age-dependent responsiveness does not reflect loss of GLP-1R signaling in adult islets, since Ex-4 treatment stimulated insulin secretion by both juvenile and adult human β cells. We show that the mitogenic effect of Ex-4 requires calcineurin/nuclear factor of activated T cells (NFAT) signaling. In juvenile islets, Ex-4 induced expression of calcineurin/NFAT signaling components as well as target genes ...

SD nephrotic syndrome carries a high risk of toxicity from steroids or standard steroid-sparing agents. Therefore, alternative treatment options are needed. Although recent studies support the use of rituximab as a steroid-sparing and CNI-sparing agent in SD-INS, benefits may be suboptimal, especially in complicated forms of the disease. The new anti-CD20 ofatumumab may be more effective than rituximab in controlling the disease, due to its stronger affinity for the CD20. Moreover, due to its fully humanised structure, it may be used in larger doses with minimal risk of side effects. These considerations motivated the use of an active comparator to test the effects of different agents blocking the CD20 antigen pathway.. This is the first randomised controlled trial comparing the effects of two anti-CD20 antibodies on the risk of relapse of INS following steroid and CNI withdrawal. Strengths in the design of this trial include: objective and clinical important outcomes, identification of a ...

Effect of Cyclosporin a on the Tumor Microenvironment by Yao ZhouEffect of Cyclosporin a on the Tumor Microenvironment by Yao Zhou
Tumor angiogenesis is a hallmark of cancer, and plays a critical role in tumor growth, expansion, and metastasis. Both physiological and pathological angiogenesis is assumed to be regulated by the balance between pro and anti-angiogenic factors. One of the best characterized and most potent pro-angiogenic regulators is vascular endothelial growth factor, or VEGF. Calcineurin signaling is an important mediator of VEGF signaling in endothelial cells. Negative regulation of calcineurin by increased expression of its endogenous inhibitor, Down Syndrome Candidate Region-1 (DSCR1), suppresses tumor growth and angiogenesis. However, a potent pharmacological calcineurin inhibitor, the commonly used immunosuppressant cyclosporin A (CsA), significantly increases the incidence of cancer in organ transplant recipients. The mechanism by which CsA promotes cancer in this patient population is not well understood and despite the significance of calcineurin signaling in endothelial cells, the consequences of CsA on

N1 - Copyright: Copyright 2009 Elsevier B.V., All rights reserved.. PY - 2009/2/16. Y1 - 2009/2/16. N2 - In recent years, a handful of research investigations have shown that some antihypertensive drugs, i.e., angiotensin-converting enzyme inhibitor (ACEI), angiotensin receptor blocker (ARB), and calcium channel blocker (CCB), can inhibit myocardial expression and/or activity of calcineurin. Calcineurin is a Ca2+-calmodulin-dependent serine/threonine phosphatase and is a target for some immunosuppressive drugs. It is well known that traditional immunosuppressants, such as cyclosporine A (CsA) and tacrolimus (FK506), are anticalcineurin, and their prohypertensive effects are such that antihypertensive therapy is often required in organ transplant recipients who receive these drugs. Therefore, the idea that ACEI, ARB, and CCBs are both ...

PY - 2016. Y1 - 2016. N2 - Autophagy is a catabolic process that recycles cytoplasmic contents and is crucial for cell survival during stress. The target of rapamycin (TOR) kinase regulates autophagy as part of two distinct protein complexes, TORC1 and TORC2. TORC1 negatively regulates autophagy according to nitrogen availability. In contrast, TORC2 functions as a positive regulator of autophagy during amino acid starvation, via its target kinase Ypk1, by repressing the activity of the calcium-dependent phosphatase calcineurin and promoting the general amino acid control (GAAC) response. Precisely how TORC2-Ypk1 signaling regulates calcineurin within this pathway remains unknown. Here we demonstrate that activation of calcineurin requires Mid1, an endoplasmic reticulum-localized calcium channel regulatory ...

Background. Benefits of conversion from calcineurin inhibitor (CNI) to mammalian target of rapamycin inhibitor-based immunosuppression in long-term kidney transplant patients remain uncertain. Methods. ASCERTAIN was a 24-month, open-label, multicenter study. Kidney transplant patients more than 6 months posttransplant receiving CNI (baseline glomerular filtration rate [GFR] 30-70 mL/min/1.73 m(2)) were randomized to everolimus with CNI elimination (n = 127) or CNI minimization (n = 144), or continued CNI unchanged (controls, n = 123) to assess the effect on measured GFR at month 24 after randomization. Results. Renal function was stable in all groups to month 24. Mean measured GFR at month 24, the primary endpoint, was 48.0 +/- 22.0 mL/min/1.73 m(2), 46.6 +/- 21.1 mL/min/1.73 m(2), and 46.0 +/- 20.4 mL/min/1.73 m(2) in the CNI elimination, CNI minimization, and control groups, respectively. Differences between CNI elimination (1.12 mL/min/1.73 m(2), 95% confidence interval [CI] -3.51 to 5.76, ...

Since first published guideline on the use of direct oral anti-coagulants (DOACs) in non-valvular atrial fibrillation on 2013 till latest update on 2018 (1), DOACs interactions with other drugs are one of the important challenges in their prescribing. By rapid growing number of solid organ transplant recipients the need for anticoagulant therapy among transplant patients is increasing. Based on in vivo studies (2, 3) and clinical reviews (4, 5) on concomitant administration of calcineurin inhibitors (CNIs) and DOACs, reassessing the color of interactions in the guideline (1) seems to be necessary. Using midazolam as CYP3A probe showed that cyclosporine inhibits CYP3A stronger than tacrolimus and there is no significant difference in CYP3A inhibition between tacrolimus and control group (2). Same pattern of inhibition is seen with P-glycoprotein (P-gp) pathway (3). Hence, considering cyclosporine as moderate to strong P-gp inhibitor and moderate CYP3A inhibitor and tacrolimus as mild to moderate ...

Subject of this study is the synthesis of easily achievable CsA analogs starting with CsA. These should be inhibitors of cyclophilin without any immunosuppressive action. Furthermore CsA derivatives should be synthesized which do not pass the cell membrane and thus are qualified to selectively inhibit extracellularly occurring cyclophilins. The synthesized derivatives have been tested for their biochemical properties, concerning the inhibition of peptidyl prolyl cis/trans isomerization and calcineurin phosphatase activity, the ability to pass cell membrane, and the NFAT-reporter gen assay, in already evaluated assay-systems. Some of the derivatives shown in this study are potent inhibitors of cyclophilin with distinct reduced immunosuppressed properties and without any inhibition of calcineurin phosphatase activity and they do not pass the cell membrane.

Results] We were able to observe 3,622 genes modulated in at least one timepoint in the mutant when compared to the wild type strain (3,211 and 411 at 10 and 30 minutes, respectively). Decreased mRNA abundance in the ΔcrzA was seen for genes encoding calcium transporters, transcription factors and genes that could be directly or indirectly involved in calcium metabolism. Increased mRNA accumulation was observed for some genes encoding proteins involved in stress response. AfCrzA overexpression in A. fumigatus increases the expression of several of these genes. The deleted strain of one of these genes, AfRcnA, belonging to a class of endogenous calcineurin regulators, calcipressins, had more calcineurin activity after exposure to calcium and was less sensitive to menadione 30 μM, hydrogen peroxide 2.5 mM, EGTA 25 mM, and MnCl2 25 mM. We constructed deletion, overexpression, and GFP fusion protein for the closely related A. nidulans AnRcnA. GFP::RcnA was mostly detected along the germling, did ...

Purpose: Calcineurin orchestrates growth, stress responses and virulence in major pathogenic fungi including Aspergillus fumigatus responsible for life-threatening fungal infections worldwide. While these cellular regulatory functions of calcineurin make it an attractive antifungal target, the immunosuppressive effects of the currently available calcineurin inhibitors, FK506 and CsA, make it difficult to exploit the antifungal potential due to conservation of calcineurin in the host and the fungal pathogen. Critical molecular understanding of calcineurin-immunophilin-immunosuppressor complexes would facilitate the design of novel non-immunosuppressive CsA and FK506 analogs for fungal-specific targeting of calcineurin.. Methods: We solved the crystal structure of calcineurin-FK506-FKBP12 complex in A. fumigatus and using site-directed mutagenic approaches, we constructed several mutations in the CnaA catalytic subunit of calcineurin and FKBP12. To identify differences between the A. fumigatus ...

Calcineurin (CN), a calcium- and calmodulin-dependent protein phosphatase, plays a significant role in the central nervous system. Previously, we reported that forebrain-specific CN knockout mice (CN mutant mice) have impaired working memory. To further analyze the behavioral effects of CN deficiency, we subjected CN mutant mice to a comprehensive behavioral test battery. Mutant mice showed increased locomotor activity, decreased social interaction, and impairments in prepulse inhibition and latent inhibition. In addition, CN mutant mice displayed an increased response to the locomotor stimulating effects of MK-801. Collectively, the abnormalities of CN mutant mice are strikingly similar to those described for schizophrenia. We propose that alterations affecting CN signaling could comprise a contributing factor in schizophrenia pathogenesis.. ...

New and emerging trends in the treatment of atopic dermatitis Christina M Gelbard1, Adelaide A Hebert1,21Departments of Dermatology; 2Pediatrics, University of Texas-Houston, Houston, TX, USAAbstract: Atopic dermatitis is a chronic, inflammatory skin condition that affects 10% to 20% of children and 1% to 3% of adults in the US. Symptoms often result in sleeplessness, psychological stress, poor self-esteem, anxiety, and poor school or work performance. The cost of atopic dermatitis is estimated to be US$0.9 to 3.8 billion every year. Topical steroids are first-line treatment for atopic dermatitis, and recent advances in vehicle technologies have resulted in improved patient tolerability and compliance. Topical calcineurin inhibitors are also safe and effective topical treatments for atopic dermatitis, and provide an additional therapeutic option for patients with this disease. Systemic immunomodulators are used in the treatment of severe refractory disease. Cyclosporine, methotrexate, azathioprine,

JCI - Calcineurin/Nfat signaling is required for perinatal lung maturation and functionJCI - Calcineurin/Nfat signaling is required for perinatal lung maturation and function
Pulmonary surfactant proteins and lipids are required for lung function after birth. Lung immaturity and resultant surfactant deficiency cause respiratory distress syndrome, a common disorder contributing to morbidity and mortality in preterm infants. Surfactant synthesis increases prior to birth in association with formation of the alveoli that mediate efficient gas exchange. To identify mechanisms controlling perinatal lung maturation, the Calcineurin b1 (Cnb1) gene was deleted in the respiratory epithelium of the fetal mouse. Deletion of Cnb1 caused respiratory failure after birth and inhibited the structural maturation of the peripheral lung. Synthesis of surfactant and a lamellar body-associated protein, ABC transporter A3 (ABCA3), was decreased prior to birth. Nuclear factor of activated T cells (Nfat) calcineurin-dependent 3 (Nfatc3), a transcription factor modulated by calcineurin, was identified as a direct activator of Sftpa, Sftpb, Sftpc, Abca3, Foxa1, and Foxa2 genes.

Calcineruin control over hyphal septation and cell wall biosynthesis. Septa are crucial in hyphal growth as they are the natural dividers in the growing hyphae, critical for continued growth and compartmentalization of cellular function. We were the first group to establish that both calcineurin subunits are stably present in the developing A. fumigatus hyphal septum, sitting as disks on each side of the septum. Calcineurin deletion mutants create septal defects and miscues in cellular metabolism. The hyphal septa is also a prime example of how important cell wall biosynthesis is for the organism. The cell wall serves as the leading point for the growing and invading hyphae as well as the first contact point with the host. The cell wall functions as both a structural component to hold the cell together as well as a scaffold for countless cellular functions. We have shown that calcineurin controls cell wall metabolism, and now we are working on uncovering the exact molecular mechanisms of ...

Hope for Significant New Diabetes Treatment in Stanford Discovery | EmaxHealth
Certain immune-suppressing drugs, such as those taken by patients who have had organ transplants, greatly increase the risk of developing diabetes. These drugs are known to put a stranglehold on a protein called calcineurin.. So its not exactly a surprise that Seung Kim, MD, PhD, assistant professor of developmental biology at the Stanford University School of Medicine, chose to study why calcineurin inhibition leads to the disease. What is surprising is just how central calcineurin turns out to be in the health and happiness of the insulin-producing pancreatic beta cells. His findings, to be published in the Sept. 21 issue of Nature, could shake up diabetes research, lead to new classes of diabetes drugs and aid in efforts to develop stem cell treatments for diabetes.. This work has the potential to be big, said Scott Campbell, PhD, vice president of research for the American Diabetes Association.

Tmem110 - WikipediaTmem110 - Wikipedia
TMEM110, also designated as STIMATE (for STIM-activating enhancer), is an ER-resident multi-transmembrane protein identified through a proteomic study on the ER-PM junctions. The ER-PM junctions are defined as specialized junctional sites, also known as membrane contact sites, that connect the endoplasmic reticulum (ER) and the plasma membrane (PM), and are closely implicated in controlling lipid and calcium homeostasis in mammalian cells. TMEM110 is a positive modulator of calcium flux mediated by the STIM-ORAI signaling in vertebrates. STIMATE can physically associate with STIM1 to promote conformational switch of STIM1 from inactive toward an activated state, thereby coupling to and gating the ORAI calcium channels on the plasma membrane. Depletion of TMEM110 with RNAi knockdown or Cas9-mediated gene disruption substantially reduces the puncta formation of STIM1 at ER-PM junctions and remarkably inhibits the calcium/calcineurin/NFAT signaling axis. More genetic and biochemical studies are ...

Transient Inhibition of Interleukin 4 Signaling by T Cell Receptor Ligation | JEMTransient Inhibition of Interleukin 4 Signaling by T Cell Receptor Ligation | JEM
In this study, it was shown that IL-4-mediated signals were strikingly but transiently inhibited by TCR engagement of naive T cells. This inhibition involved triggering of both the PKC-MAPK and calcineurin pathways. It has recently been reported by Ivashkiv and colleagues that the IL-2 signal was inhibited by TCR engagement in preactivated T cells and the inhibition was mediated by the PKC-MAPK pathway (35). We have also checked the IL-4 signal in activated cells and observed results quite similar to those described above for naive T cells (data not shown). In addition, we found that the IL-2 signal was also inhibited by TCR engagement in naive T cells. McMahon and colleagues have shown that sustained activation of the Raf-MEK-ERK pathway elicited cytokine unresponsiveness in T cells (46). These results are consistent in indicating that MAPK plays an important role in the cross-talk between TCR and cytokine signals. Our data further show that although MAPK activation is necessary, it is not ...

Regulation of GATA-3 Expression during CD4 Lineage Differentiation | The Journal of ImmunologyRegulation of GATA-3 Expression during CD4 Lineage Differentiation | The Journal of Immunology
GATA-3 is necessary for the development of MHC class II-restricted CD4 T cells, and its expression is increased during positive selection of these cells. TCR signals drive this upregulation, but the signaling pathways that control this process are not well understood. Using genetic and pharmacological approaches, we show that GATA-3 upregulation during thymocyte-positive selection is the result of additive inputs from the Ras/MAPK and calcineurin pathways. This upregulation requires the presence of the transcription factor c-Myb. Furthermore, we show that TH-POK can also upregulate GATA-3 in double-positive thymocytes, suggesting the existence of a positive feedback loop that contributes to lock in the initial commitment to the CD4 lineage during differentiation. ...

However, depending on the amplitude of the Ca2+ signal as well as the condition of the cell, Ca2+ can also initiate apoptosis as a consequence of organelle disruption, free radical production, and the activation of Ca2+-dependent phosphatases and proteases such as calcineurin and calpain (96).. The release of Ca2+ from the ER is a critical early event for the initiation of apoptosis induced by many apoptotic signals (115). The sensitivity of a cell to such apoptotic stimuli appears to be largely dependent on the ER Ca2+ load, with a high resting ER Ca2+ concentration sensitizing cells to apoptotic stimuli and a low ER Ca2+ concentration conferring resistance. Once released into the cytosol, Ca2+ is rapidly adsorbed by mitochondria that can trigger apoptotic responses by disrupting the mitochondrial respiratory chain and generating reactive oxygen species or by opening the PTP (122).. The original finding that Bcl-2 affected Ca2+ signaling was discovered over a decade ago. In these studies, Bcl-2 ...

ES increased expression of Hey1 and Pitx2 suggesting increased Notch and Wnt signaling, respectively, but did not normalize RCAN1.4, a measure of calcineurin/NFAT signaling, or PGC-1ß mRNA levels. ES increased PGC-1α expression but not that of slow myofibrillar genes. Microarray analysis showed that after ES, genes coding for calcium binding proteins and nicotinic acetylcholine receptors were increased, and the expression of genes involved in blood vessel formation and morphogenesis was altered. Of the 165 genes altered by ES only 16 were also differentially expressed after GA, of which 12 were altered in the same direction by ES and GA. In contrast to ES, GA induced expression of genes related to oxidative phosphorylation ...

The basis for increased mortality after heart transplantation in African Americans and other non-Caucasian racial groups is poorly defined. We hypothesized that increased risk of adverse events is driven by biologic factors. To test this hypothesis in the Invasive Monitoring Attenuation through Gene Expression (IMAGE) study, we determined whether the event rate of the primary outcome of acute rejection, graft dysfunction, death, or retransplantation varied by race as a function of calcineurin inhibitor (CNI) levels and gene expression profile (GEP) scores.We determined the event rate of the primary outcome, comparing racial groups, stratified by time after transplant. Logistic regression was used to compute the relative risk across racial groups, and linear modeling was used to measure the dependence of CNI levels and GEP score on race.In 580 patients monitored for a median of 19 months, the incidence of the primary end point was 18.3% in African Americans, 22.2% in other non-Caucasians, and ...

Sampling Serum in Patients With Vitiligo to Measure Disease Activity i by and John E. HarrisSampling Serum in Patients With Vitiligo to Measure Disease Activity i by and John E. Harris
In this issue of JAMA Dermatology, Speeckaert and colleagues report that levels of the soluble CD25 and CD27 molecules (sCD25 and sCD27) are elevated in the serum of patients with active vitiligo compared with patients with stable disease. In addition, sCD25 levels were found to be significantly lower in the serum of patients being treated with topical immunosuppressants (including steroids and calcineurin inhibitors) and the serum level of sCD27 was significantly lower in patients with recent repigmentation, suggesting a potential to use these as biomarkers to monitor treatment responses. Interestingly, the authors continued to prospectively study a relatively large number of participants and demonstrated that serum levels of both sCD25 and sCD27 were associated with disease progression during follow-up. These important findings suggest that monitoring of these markers in the serum of patients with vitiligo may provide a glimpse into what is happening in the skin, a process that is not obvious by

Immunology
Emory scientists have identified troublemaker cells-present in some patients before kidney transplantation-that are linked to immune rejection after transplant. Their results could guide transplant specialists in the future by helping to determine which drug regimens would be best for different groups of patients. Eventually, the findings could lead to new treatments that improve short- and long-term outcomes.. Transplant patients used to have no choice but to take non-specific drugs to prevent immune rejection of their new kidneys. While these drugs, called calcineurin inhibitors, are effective at preventing early rejection, they lack specificity for the immune system and ironically can damage the very kidneys they are intended to protect. In addition, their side effects lead to higher rates of high blood pressure, diabetes, and cardiovascular disease, ultimately shortening the life of the transplant recipient. This changed with the advent of costimulation blockers, which avoid these harmful ...
