Objectives: Chronic diabetes impedes cardioprotection in reperfusion injury and hence protecting the diabetic heart would have important outcomes. In this study, we evaluated whether combined postconditioning with ischemia and cyclosporine-A can restore oxidative stress and histopathological changes in reperfusion injury of the diabetic myocardium. Materials and Methods: Streptozocin-induced diabetic hearts and nondiabetic controls in eight subgroups (with or without receiving ischemic-postconditioning (IPostC), cyclosporine-A, an inhibitor of mitochondrial permeability transition, or both of them) suffered from 30 min regional ischemia followed by 45 min reperfusion on an isolated-heart Langendorff system...

Invasion of human erythrocytes by Plasmodium falciparum merozoites involves multiple interactions between host receptors and their merozoite ligands. Here we report human Cyclophilin B as a receptor for PfRhopH3 during merozoite invasion. Localization and binding studies show that Cyclophilin B is present on the erythrocytes and binds strongly to merozoites. We demonstrate that PfRhopH3 binds to the RBCs and their treatment with Cyclosporin A prevents merozoite invasion. We also show a multi-protein complex involving Cyclophilin B and Basigin, as well as PfRhopH3 and PfRh5 that aids the invasion...

Primary nephrotic syndrome (NS) is the most common glomerular disease in children. It is characterized by massive proteinuria and hypoalbuminemia. It typically has a sudden onset and more than 70% of patients will experience at least one relapse. An immunological origin has long been postulated, although the precise molecular mechanisms underlying the disease remain debated. Steroids are the first-line therapy with cumulative dose and duration of initial treatment varying among countries. Steroid-sparing agents may be indicated in case of steroid-dependency or frequent relapses...

Psoriasis is a common disease, which has a considerable impact on patients and the health care system. Treatment approaches to the disease may be various because some issues are not definitely addressed. Moreover, the therapeutic paradigms are continuously changing because of the recent approval of new treatments for psoriasis such as interleukin (IL)-17 inhibitors and apremilast. In this review, the factors influencing psoriasis severity, the indications for systemic treatments, the overall parameters to be considered in the treatment choice, life style interventions, and the recommendations for the use, screening, and monitoring of systemic therapies available including acitretin, cyclosporine, methotrexate, apremilast, adalimumab, etanercept, infliximab, secukinumab, ixekizumab, and ustekinumab are discussed...

Fumonisins were first discovered in Fusarium verticillioides, a fungus associated to disease and asymptomatic infections in maize. Afterwards, other fungal taxa have been found to produce fumonisins. The entomopathogenic ascomycete Tolypocladium cylindrosporum has been isolated from soil and also as an endophyte from leaves of grasses. The objectives of this work were to determine the in vitro production of fumonisin B (FB) mycotoxins and the immunosuppressive compound cyclosporine A (CyA) in several strains of T...

Acquired aplastic anemia (AA) is a rare, life-threatening bone marrow failure (BMF) disorder that affects patients of all ages and is caused by lymphocyte destruction of early hematopoietic cells. Diagnosis of AA requires a comprehensive approach with prompt evaluation for inherited and secondary causes of bone marrow aplasia, while providing aggressive supportive care. The choice of frontline therapy is determined by a number of factors including AA severity, age of the patient, donor availability, and access to optimal therapies...

Minor infections, allergies, insect bites, and bee stings are commonly reported causes of nephrotic syndrome (NS). Herein, we report, to the best of our knowledge, the first case of NS relapse due to Kawasaki disease (KD). An 8-year-old boy presented with high fever of 4-day duration. He had developed steroid-dependent NS at the age of 4 years and remained in remission after steroid and mizonbin therapy. Renal biopsy, performed at the age of four, showed minimal change (MC) disease. Upon examination, the patient fulfilled 5 of 6 criteria for KD under the Japanese diagnostic guidelines, with positive proteinuria...

Actinic prurigo is a pruritic sun-induced dermatosis classified among the immunologically mediated photodermatoses. The disease is a well-known entity among Native Americans and in Central and South America, however rare in Caucasians with only a few reports from Australia, Britain and France. We report the first case of actinic prurigo in a Scandinavian patient, responding favorably to systemic treatment with cyclosporine A.

With the purpose to explore the mechanisms associated with the intestinal toxicity of OTA, an intestinal porcine epithelial cell line (IPEC-J2) was applied in this study as in vitro models for intestinal epithelium. The results confirmed that OTA induced IPEC-J2 cell toxicity by MTT assay and apoptosis by Hoechst 33258 staining and flow cytometer analysis. And then, we observed that OTA induced the mitochondrial reactive oxygen species (ROS) production and mitochondrial permeability transition pore (mPTP) opening by confocal microscopy...

BACKGROUND: The interindividual variability of cyclosporin A (CsA) pharmacokinetics might be explained by heterogeneity in the cytochrome P450 3A (CYP3A) subfamily. Altered CYP3A enzyme activity was associated with variant allele of P450 oxidoreductase gene (POR*28). The aim of this study was to assess the impact of age, CYP3A5*3, CYP3A4*22, and POR*28 alleles on CsA pharmacokinetics in pediatric renal transplant recipients. METHODS: Renal transplant patients receiving CsA (n = 47) were genotyped for CYP3A5*3, CYP3A4*22, and POR*28...

The calcineurin inhibitor cyclosporine A (CsA) suppresses the immune system but promotes hypertension, vascular dysfunction, and renal damage. CsA decreases regulatory T cells and this contributes to the development of hypertension. However, CsA's effects on another important regulatory immune cell subset, myeloid-derived suppressor cells (MDSCs), is unknown. We hypothesized that augmenting MDSCs would ameliorate the CsA-induced hypertension and vascular and renal injury and dysfunction and that CsA reduces MDSCs in mice...

In rat vascular smooth muscle cells (RVSMC), 3-h Na(+),K(+)-ATPase inhibition by ouabain or in K(+)-free medium resulted in the inversion of the [Na(+)]i/[K(+)]i ratio and elevation up to 7-fold the content of Egr1, Atf3, Nr4a1 and Ptgs2 mRNAs. Ouabain increased the rate of 45Ca(2+) influx by 2-fold that was abolished by L-type voltage-gated Ca(2+) channel blocker nicardipine, but it was resistant to Na(+)/Ca(2+) exchanger inhibitor KB-R7943. To study the role of Ca(2+)-mediated signaling in the expression of Na(+)i/K(+)i-sensitive genes we used intracellular Ca(2+) chelator BAPTA and incubated RVSMC in Ca(2+)-free medium...

Graves orbitopathy (GO) occurs in 25-50 % cases of Graves disease. Only in 5 % of patients the eye threatening GO is present. About 5-10 % and 10 % cases are present in euthyroid and hypothyroid patients respectively. All patients with GO should be assessed for activity (clinical activity score - CAS) and severity of the disease. Basic preconditions of the treatment are maintenance of euthyroidism, an effort to stop smoking, and referring of patients with moderate to severe and sight threatening GO to specialized thyroid eye centers...

The implantable cuff electrode is an effective neuroprosthetic device in current nerve tissue engineering. However, biocompatibility and stability are still a serious dispute in terms of in vivo function and continuous monitoring. In this regard, assessing the host's biological response to biomaterials is one of the key factors of chronic implantation. In this article, we analyzed the peripheral nerve specific-biological responses to the application of multi-functional hydrogel-coated electrodes. The surface of the cuff electrode was modified using a multifunctional hydrogel composed of PEG hydrogel, cyclosporin A(CsA)-microsphere(MS) and electrodeposited PEDOT:PSS...

Loss of protein homeostasis is a hazardous situation that jeopardizes cellular functionality and viability. Cells have developed mechanisms that supervise protein integrity and direct misfolded molecules for degradation. Nevertheless, subsets of aggregation-prone proteins escape degradation and form aggregates that can underlie the development of neurodegenerative disorders. In some cases, cells deposit hazardous protein aggregates in designated sites, like aggresomes, or secrete them with vesicles. The prion protein (PrP) is an aggregation-prone, membrane-anchored glycoprotein, whose aggregation causes familial and sporadic, fatal, neurodegenerative diseases...

Cyclosporine A (CSA) is a widely used immunosuppressant drug known to commonly cause cardio and nephrotoxicity. A study looking at the sex specificity of the cardiotoxicity of CSA revealed that sexual dimorphism existed when looking at the electrocardiographs and left ventricles of CSA-treated rats. We hypothesized that cyclosporine A exhibited gender-specific nephrotoxicity by testing various parameters of kidney function in male and female rats treated for 21 days with 15 mg/kg CSA versus control male and female rats that received a vehicle consisting of 18% kolliphore and 2% ethanol in sterile saline...
