The Jak-Stat Signaling Pathway of Interferons System: Snapshots
Interferons (IFNs) are a family of small regulatory glycoproteins that play a central role in the defense against viral infections. Although IFNs have been initially discovered as antiviral factors, today they are known as an integral part of the cytokine network that affect a wide range of biological processes. IFNs exert their pleiotropic effects through their multisubunit cell surface recept...
متن کاملExploring the role of dimethylarginine dimethylaminohydrolase-mediated reduction in tissue asymmetrical dimethylarginine levels in cardio-protective mechanism of ischaemic postconditioning in rats
Objective(s): Reperfusion of ischaemic myocardium results in reduced nitric oxide (NO) biosynthesis by endothelial nitric oxide synthase (eNOS) leading to endothelial dysfunction and subsequent tissue damage. Impaired NO biosynthesis may be partly due to increased levels of asymmetrical dimethylarginine (ADMA), an endogenous inhibitor of eNOS. As dimethylarginine dimet...
متن کاملJAK-STAT pathway and JAK inhibitors: a primer for dermatologists
Background: All cellular events depend upon the DNA synthesis and gene expression involving complex interplay between ligands such as interleukins and interferons, with various cell membrane receptors. These ligand-receptors interactions transmit signals within the cell via numerous signal transduction pathways to affect gene expression. Janus kinase/signal transducer and activator of transcrip...
متن کاملThe role of hormones in renal disease and ischemia-reperfusion injury
The patients with renal diseases, especially end-stage renal disease (ESRD), are at high risk of developing cardiovascular disturbances. Some hormones such as brain natriuretic peptide appear to be important serum biomarkers in predicting cardiac death in ESRD patients. Renal diseases cause inflammation, anemia, uremic toxins, fluid overload, and electrolyte disturbance. Kidney transplantation ...
متن کاملInduction of protein synthesis in cardiac fibroblasts by cardiotrophin-1: integration of multiple signaling pathways.
OBJECTIVE Cardiotrophin-1 (CT-1) is a member of the IL-6 family of cytokines and is expressed in various cardiovascular disease states. CT-1 induces cardiomyocyte hypertrophy, and protects myocytes from ischemia reperfusion injury. We sought to elucidate CT-1 signaling in cardiac fibroblasts with respect to initiation of protein synthesis. METHODS Cardiac fibroblasts were isolated from the ve...
