Diabetes alpha and beta cells
Did you know?
WebSeveral studies have shown that the pancreases of subjects with type 2 diabetes display a severe beta cell deficit due to increased beta cell apoptosis [16, 17, 37, 38], and normal or increased alpha cell number [5, 13–15, 19]; interestingly, these alterations are also present in diabetic and insulin resistant/obese baboons [31, 33]. WebThe two most abundant and prominent endocrine cell types, the beta and the alpha cells, are essential for the maintenance of blood glucose homeostasis. While the beta cell produces insulin, the only blood glucose-lowering hormone of the body, the alpha cell releases glucagon, which elevates blood glucose.
