The sodium-glucose cotransporter 2 (SGLT-2) inhibitors are a novel class of glucose-lowering drugs which act by inhibiting the reabsorption of filtered glucose from the kidneys. Their effect on insulin and glucagon levels has recently been studied but is not fully explained. This communication proposes various hypotheses: A direct effect of SGLT-2 inhibition on the alpha cell receptors, a paracrine or intra-islet mediated effect on alpha cell sensitivity to glucose, and a calorie restriction mimetic action, to explain the impact of these drugs on the insulin glucagon ratio.
钠-葡萄糖协同转运蛋白2(SGLT-2)抑制剂是一类新型降糖药物,其作用机制是抑制肾脏对滤过葡萄糖的重吸收。最近对其对胰岛素和胰高血糖素水平的影响进行了研究,但尚未完全阐明。本通讯提出了各种假设:SGLT-2抑制对α细胞受体的直接作用、旁分泌或胰岛内介导的对α细胞对葡萄糖敏感性的作用,以及类似热量限制的作用,以解释这些药物对胰岛素与胰高血糖素比值的影响。
