Cytomegalovirus (CMV) anterior uveitis and endotheliitis occurs among immunocompetent individuals and may manifest as Posner-Schlossman syndrome or Fuchs uveitis syndrome. The condition may first present following ophthalmic surgery, the use of a fluocinolone-sustained steroid drug delivery implant, or the use of topical prostaglandin analogues for the treatment of glaucoma. We report the first case of a non-human immunodeficiency virus-infected individual who presented with CMV anterior uveitis after the use of topical cyclosporine A 0...

Lupus miliaris disseminatus faciei (LMDF) is a chronic, inflammatory dermatosis of unknown etiology, characterized by multiple, monomorphic, symmetrical, reddish-brown papules over forehead, cheeks, and eyelids. Histopathology shows perifollicular epitheloid cell granuloma. Though numerous therapies, ranging from cyclines, macrolides, dapsone tranilast, isotretinoin, steroids, and tacrolimus have been tried, the results are inconsistent, except with systemic steroids. One approach is to administer therapies based on the histological findings and the corresponding mode of action of drugs, thus antibiotics and dapsone are effective in the early inflammatory stage while clofazamine can be used in the granulomatous stage of the disease...

Idiopathic pulmonary fibrosis (IPF) is a chronic lung disorder that is characterized by aberrant tissue remodeling and the formation of fibroblastic foci that are composed of fibrogenic myofibroblasts. TGF-β1 is one of the factors that are responsible for fibrosis as it promotes fibroblast to myofibroblast differentiation (FMD) and is associated with up-regulation of α-smooth muscle actin. Therefore, inhibition of FMD may represent an effective strategy for the treatment of IPF. Here, we describe the treatment of human lung fibroblasts (WI-38 and HFL-1 cells) with cyclosporine A (CsA), which reduces TGF-β1-induced FMD via degradation of hypoxia-inducible factor-1α (HIF-1α)...

The Cyclophilin A (CypA)/Apoptosis Inducing Factor (AIF) complex is implicated in the DNA degradation in response to various cellular stress conditions, such as oxidative stress, cerebral hypoxia-ischemia and traumatic brain injury. The pro-apoptotic form of AIF (AIF(Δ1-121)) mainly interacts with CypA through the amino acid region 370-394. The AIF(370-394) synthetic peptide inhibits complex formation in vitro by binding to CypA and exerts neuroprotection in a model of glutamate-mediated oxidative stress. Here, the binding site of AIF(Δ1-121) and AIF(370-394) on CypA has been mapped by NMR spectroscopy and biochemical studies, and a molecular model of the complex has been proposed...

Given the social importance of intracranial aneurysm as a major cause of a lethal subarachnoid hemorrhage, clarification of mechanisms underlying the pathogenesis of this disease is essential for improving poor prognosis once after rupture. Previous histopathological analyses of human aneurysm walls have revealed the presence of T cells in lesions suggesting involvement of this type of cell in the pathogenesis. However, it remains unclear whether T cell actively participates in intracranial aneurysm progression...

Posttransplant diabetes mellitus (PTDM) is one of the major metabolic complications after transplantation of solid organs including the kidney. This type of diabetes mellitus affects allograft survival, cardiovascular complications and overall patient survival. The modifiable risk factors that contribute to PTDM include obesity, some viral infections (eg, hepatitis C virus, cytomegalovirus) and especially immunosuppressive drugs including corticosteroids, tacrolimus, cyclosporine and sirolimus. Currently, predisposing genetic factors have been considered important in PTDM development...

Cocaine abuse induces brain injury and neurodegeneration by a mechanism that has not yet been fully elucidated. Mitochondria play a key role in cell death processes, notably through the opening of the permeability transition pore (PTP). In this work, we examined the involvement of the PTP in cocaine-induced toxicity in PC12 cell lines. We used two different PTP inhibitors -i.e. cyclosporin A (CsA) and metformin-to assess their ability to counteract the cocaine induced effects. We first observed that a 48 h exposure to cocaine strongly sensitized cells to calcium overload, as measured by the calcium retention capacity...

β-cell transcription factors like: FoxO1, MafA, PDX-1, NeuroD, are dysfunctional in type 2 diabetes (T2DM). PTDM resembles T2DM and reflects interaction between pre-transplant insulin resistance and immunosuppressants, mainly calcineurin inhibitors. We evaluated the effect of tacrolimus, cyclosporine-A and metabolic stressors (glucose+palmitate) on insulinoma β-cells (INS-1) in vitro and in pancreata of obese and lean Zucker rats. Cells were cultured for five days with 100μM palmitate and 22mM glucose; cyclosporin-A (250ng/mL) or tacrolimus (15ng/mL) were added the last 48h...

Aberrant methylation change of IRF8 confers risk to various tumors, and abnormal expression of IRF8 is involved in many autoimmune diseases, including ocular Behcet's disease. However, whether the methylation change of IRF8 is associated with Vogt-Koyanagi-Harada (VKH) disease remains unknown. In the present study, we found a decreased IRF8 mRNA expression in association with a higher methylation level in monocyte-derived dendritic cells (DCs) from active VKH patients compared with the normal and inactive subjects...

Animal studies have shown that the calcineurin inhibitors (CNIs) cyclosporine and tacrolimus can activate the thiazide-sensitive NaCl cotransporter (NCC). A common side effect of CNIs is hypertension. Renal salt transporters such as NCC are excreted in urinary extracellular vesicles (uEVs) after internalization into multivesicular bodies. Human studies indicate that CNIs also increase NCC abundance in uEVs, but results are conflicting and no relationship with NCC function has been shown. Therefore, we investigated the effects of CsA and Tac on the abundance of both total NCC (tNCC) and phosphorylated NCC at Thr60 phosphorylation site (pNCC) in uEVs, and assessed whether NCC abundance in uEVs predicts the blood pressure response to thiazide diuretics...

Statins are efficient cholesterol-lowering medicines utilized worldwide. However, 10% of patients suffer from adverse effects specially related to skeletal muscle function. Pro- or anti-oxidant effects of statins have been reported. Here we hypothesized that statins induce muscle mitochondrial oxidative stress leading to mitochondrial permeability transition (MPT) which may explain statin muscle toxicity. Thus, our aims were to investigate the effects of statin chronic treatment on muscle mitochondrial respiration rates, MPT and redox state indicators in the context of hypercholesterolemia...
