background: type 2 diabetes (t2d) is a chronic metabolic disorder in which beta-cells are destroyed. the islet amyloid polypeptide (iapp) produced by beta-cells has been reported to influence beta-cell destruction. objective: to evaluate if iapp can act as an autoantigen and therefore, to see if cd8 + t-cells specific for this protein might be present in t2d patients. methods: peripheral blood ...

هدف: کشت سلول های اسپرماتوگونی و تولید سلول های پر توان embryonic stem cells (es like cells) که دارای قابلیت بازسازی و تولید هرسه نوع لایه زایای جنینی می باشند، این سلول ها را به عنوان منبع کافی و جدیدی برای سلول درمانی و ترمیم در بیماریها از جمله بیماریهای نورودژنراتیو پیشنهاد می دهد. در تحقیق حاضر تمایز سلول های اسپرماتوگونی موش به سلول های شبه الیگودندروسیت و نقش آنها درمیلین سازی پس از پیون...

Objective(s):The purpose of this study was to investigate the effects of Noggin on high glucose-induced apoptosis and insulin secretion in pancreatic beta cells. Materials and Methods: Different concentrations of glucose were used to examine their effects on INS-1 rat beta cells in vitro. When specific siRNA targeting Noggin and recombinant Noggin were added, apoptosis and insulin secretion wer...

Background and objectives: Melissa officinalis (MO) has shown antioxidant and anti-inflammatory properties and is traditionally believed to have anti-hyperglycemic effects. This study aims to evaluate the protective effects of MO on streptozotocin (STZ) induced pancreatic damage and thereupon diabetes in rats. Methods: STZ (60 mg/kg) was injected intraperitoneally to the rats in order to induc...

Background: Type-I diabetes is an autoimmune inflammatory disease in which pancreatic ß-cells are selectively destroyed by infiltrating cells. TNF-related apoptosis-inducing ligand (TRAIL) is a type-II membrane protein of the TNF superfamily which is expressed in different tissues, including pancreas and lymphocytes. In humans, TRAIL interacts with four membrane receptors. TRAIL-R1 and TRAIL-R2...

Mesenchymal stem cells (MSCs) have the ability to differentiate into neuronal like cells under appropriate culture condition. In this study, we investigated whether MSCs derived from human peripheral blood (PB-MSCs) can differentiate into neuronal like cells by synergic effect of the growth factors EGF, bFGF and Noggin. For this purpose, the expression of five neuronal markers (Nestin, &beta II...
