MGAM2 and type 2 diabetes mellitus: The results accumulated over the past 50 years (including studies on young animals) have shown that the main intestinal glucosidases (for example, glucoamylase, maltase) and glucose transporters in brush border membrane enterocytes (SGLT1, which actively transports glucose, and GLUT2, a transporter that operates via facilitated diffusion) are crucial for the formation of hyperglycemia in T1D and T2D [4,10,11,12,13].
