Résumé
Type 2 diabetes mellitus results from an inadequate adaptation of the functional pancreatic beta cell mass in the face of insulin resistance. Apoptosis is programmed cell death or cell suicide, it is an energy-requiring process that involves de novo protein synthesis. Apoptotic mechanisms could explain insulin deficiency through a reduction in absolute beta cell mass. This study was conducted on 49 patients with type 2 diabetes mellitus from Internal Medicine Department, Kasr- El Aini hospital. They were classified into group A [10 patients] without micro vascular complications, group B [39 patients]with micro vascular complication [peripheral neuropathy, retinopathy and nephropathy] and 10 healthy persons served as control group[group C].All subjects were subjected to full Clinical assessment and routine laboratory investigations, 24 hours urinary albumin, ECG, fundus examination and quantitative assay of proapoptotic markers [Fas, FasL, and Bcl2 proteins] There was significant correlation behveen fasting blood glucose and Fas, FasL, and Bcl2 [P value
