Front Cover. Amylin (islet amyloid polypeptide (IAPP)) is one of the hormones that regulate carbohydrate metabolism. Unfortunately, it aggregates, and amyloid aggregates bind to intra‐ and extracellular proteins and proteoglycans to form amyloid deposits which, filling the intercellular space, destroy the normal structure and functions of tissues. Aggregation of IAPP is responsible for extracellular amyloid formation which may contribute to B cells degeneration and impaired insulin secretion. Thinking about the process of inhibition of the aggregation of amylin, it is necessary to disturb the ability of β‐structures to interaction, which translates into inhibition of the deposit growth. Within the aggregating proteins/polypeptides there are hot spots determining the aggregation of the whole protein. Therefore, the search for inhibitors of the aggregation of the proteins/polypeptides is necessary to characterize them. The identified new amylin fragments prone to aggregation may be the starting point for the search for their analogues capable of interacting with the hormone and inhibiting its aggregation ability as reported by Kolesinska et al. in their full paper at10.1002/cbdv.202000501.

封面:易于聚集的新人类胰岛淀粉样多肽片段(C&B 9/2020)

封面。胰岛淀粉样多肽(胰岛淀粉样多肽(IAPP))是调节碳水化合物代谢的激素之一。不幸的是,它聚集在一起,淀粉样蛋白聚集体与细胞内和细胞外蛋白质和蛋白聚糖结合形成淀粉样蛋白沉积物,这些沉积物填满细胞间空间,破坏组织的正常结构和功能。IAPP的聚集负责细胞外淀粉样蛋白的形成,可能导致B细胞变性和胰岛素分泌受损。考虑抑制胰岛淀粉样多肽聚集的过程,有必要破坏β结构相互作用的能力,这转化为对沉积物生长的抑制。在聚集的蛋白质/多肽中,有确定整个蛋白质聚集的热点。因此,寻找蛋白质/多肽聚集抑制剂以表征它们是必要的。鉴定出的易于凝集的新胰岛淀粉样多肽片段可能是寻找其能够与激素相互作用并抑制其聚集能力的类似物的起点,Kolesinska等。在他们的全文中(at10.1002 / cbdv.202000501)。
