The present study aimed to analyze the expression levels and localizations of heat shock protein (HSP) 60 and HSP10 in the heart tissue of rats subjected to heat stress (42°C) for 0, 20, 80 and 100 min. Histopathological injuries and increased serum activities of serum lactate dehydrogenase and creatine kinase isoenzyme MB were detected in the heated rat myocardial cells. These results suggeste...
CD4+CD25+ Tregs regulate immunity, but little is known about their own regulation. We now report that the human 60-kDa heat shock protein (HSP60) acts as a costimulator of human Tregs, both CD4+CD25int and CD4+CD25hi. Treatment of Tregs with HSP60, or its peptide p277, before anti-CD3 activation significantly enhanced the ability of relatively low concentrations of the Tregs to downregulate CD4...
The aim of the study was to optimize conditions for producing Salmonella Enteritidis recombinant heat shock protein 60 (rHsp60). Seven Escherichia coli host strains (Rosetta, Turner, C41, C43, Origami, BL21pLys, Rosetta pLys) were transformed by a recombinant plasmid containing Hsp60 gene from Salmonella Enteritidis, and then cultured and induced by isopropyl-beta-D-thiogalactopyranoside (IPTG)...
Abstract Background Acute pancreatitis (AP) lacks targeted prevention and treatment measures. Some key points in the pathogenesis of AP remain unclear, such as early activation pancreatic enzymes. Several recent reports have shown protective effect hydrogen on several animal models, mechanism is related to antioxidant activity. Heat shock protein 60 (Hsp60) known accompany enzymes synthesis sec...
Heat shock protein (HSP)60 is primarily a mitochondrial protein. Previous experiments have found that changes in the location of intracellular HSP60 have been associated with apoptosis. Extracellular HSP60 mediates apoptosis via its ligand, Toll-like receptor (TLR)-4. TLR-4 is an important factor expressed on microglia, with a central role in generating neuroimmune responses in the pathogenesis...
Nonobese diabetic (NOD) mice spontaneously develop diabetes as a consequence of an autoimmune process that can be inhibited by immunotherapy with the 60-kDa heat shock protein (hsp60), with its mycobacterial counterpart 65-kDa (hsp65), or with other Ags such as insulin and glutamic acid decarboxylase (GAD). Microbial infection and innate signaling via LPS or CpG motifs can also inhibit the spon...
Proteins of selected embryonic stages were metabolically labeled with [(35)S]-methionine and analyzed by two-dimensional SDS-polyacrylamide gel electrophoresis (2-D PAGE) to study protein expression from 4- to 8-cell to blastocyst stage of porcine embryos. Two proteins with molecular weights of 60 and 72kDa were de novo synthesized during the 4- to 8-cell stage were the earliest that were detec...
سابقه و هدف: پروتئین های شوک گرمائی (heat shock proteins یا به اختصار hsps) به عنوان chaperone های مولکولی عمل کرده و از طریق تنظیم تا خوردگی و انتقال درون سلولی پروتئین های تازه سنتز شده، سلول را در مقابل صدمات ناشی از استرس های محیطی، محافظت می کنند. این مطالعه با هدف مشخص کردن ژن hsp60 در درماتوفیت پاتوژن میکروسپوروم کانیس انجام شد مواد و روش ها: نمونه قارچ میکروسپوروم کانیس از بیماران مبتلا...
سابقه و هدف: دیابت ملیتوس نوع 1 بیماری مزمن غده پانکراس و حاصل تخریب واکنش های خودایمنی سلول های بتا تولید کننده انسولین می باشد. واکنش های ایمنی مدت ها قبل از بروز تظاهرات بالینی بیماری شروع می شود. از این رو یافتن مارکر نشان دهنده شروع واکنش های خودایمنی از ارزش خاصی برخوردار است. از آنجایی که آنتی ژن شوک حرارتی-60 (Hsp60) از آنتی ژن های مطرح در دیابت نوع 1 می باشد بر آن شدیم تا کلاس ها و زیر...
Legionella pneumophila 2064 was selectively radiolabelled in mouse L929 cells and human monocytes to identify proteins expressed early in the course of infection. Polypeptide profiles (sodium dodecyl sulfate-polyacrylamide gel electrophoresis and fluorography) of adherent or intracellular bacteria indicated that a 60-kDa stress protein (Hsp60) was preferentially synthesized. Hsp60 synthesis was...
