Background: Islet transplantation could be an ideal alternative treatment to insulin therapy for type 1 diabetes Mellitus (T1DM). This clinical and experimental field requires a model that covers problems such as requiring a large number of functional and viable islets, the optimal transplantation site, and the prevention of islet dispersion. Hence, the methods of choice for isolation of functi...

Background: Pancreatic islet transplantation has emerged as a promising treatment for type I diabetes. However, its efficacy is severely hampered due to poor islet engraftment and revascularization, which have been resulted to partially loss of transplanted islets. It has been shown that local delivery of vascular endothelial growth factor (VEGF) could accelerate transplanted islet revasculari...

Objective(s): During type-1 diabetes treating by pancreatic islet transplantation, increasing oxidative stress and microbial contaminations are the main reasons of transplantation failure. In this study, we evaluated anti-apoptotic, antioxidant and antimicrobial potentials of phenolic compounds called ellagic acid (EA) and silybin on rat pancreatic islets. Materials and Methods: By doing MTT as...

Ischemic preconditioning (IPC) confers tissue resistance to subsequent ischemia in several organs. The protective effects are obtained by applying short periods of warm ischemia followed by reperfusion prior to extended ischemic insults to the organs. In the present study, we evaluated whether IPC can reduce pancreatic tissue injury following cold ischemic preservation. Rat pancreata were expos...

Pancreatic islet transplantation has been remarkably improved by the Edmonton protocol; however, it is not easy to achieve insulin independence after islet transplantation from one donor pancreas. The islet isolation procedure itself destroys cellular and noncellular components of the pancreas that probably play a role in supporting islet survival. Further islet transplantation exposes cells to...

The clinical success rate of islet transplantation, namely independence from insulin injections, is limited by factors that lead to graft failure, including inflammation, acute ischemia, phase response, and insufficient vascularization. ischemia vascularization both high levels oxidative stress, which are further aggravated encapsulation, undesirable cell-biomaterial interactions. To identify b...

Background: Pancreatic islet transplantation has been reported as an appropriate method for treatment of type I diabetes patients, however there are strong indications that cytokine and chemokines secreted from transplanted islets play an important role in islet graft rejection in different stage post-transplantation. The NF-kB signaling pathway is activated in response to the stress resulted f...

Article history: Received on: 19/03/2017 Accepted on: 12/05/2017 Available online: 30/06/2017 Cyclosporine A (CsA) is a widely used immunosuppressant in transplantation medicine. However, it has oxidative stress-induced side effects, including nephrotoxicity, hypertension, dyslipidemia, and glucose intolerance; particularly, post-transplant diabetes mellitus, accompanied by alterations of pancr...
