Résumé
Under the influence of inflammation, pancreatic β cells can transdifferentiate into cells with a different phenotype. When inflammation decreases, the opposite process is possible. We studied the effect of intramuscular injection of 5-amino-2,3-dihydrophthalazine-1,4-dione sodium salt (APH) on the structural and functional characteristics of the pancreatic islets in rats with experimental type 2 diabetes mellitus. Insulin-producing, glucagon-producing, and proliferating cells were identified by immunohistochemistry. After APH administration, an increase in the number of β cells, a decrease in the number of α cells and cells synthesizing both insulin and glucagon (insulin-glucagon-positive) were observed; mitotic activity of β cells did not change. It is likely that APH promotes transdifferentiation of α cells into β cells by changing the microenvironment of endocrine cells and reducing inflammation in pancreatic islets.
