hIAPP fibrillization implicated in Type 2 diabetes pathology involves formation of oligomers toxic to insulin producing pancreatic beta-cells. We report design, synthesis, 3D structure and functional characterization of dehydrophenylalanine (DeltaF) containing peptides which inhibit hIAPP fibrillization. The inhibitor protects beta-cells from hIAPP induced toxicity.
hIAPP 纤维化与 2 型糖尿病病理有关,涉及对产生胰岛素的胰腺 β 细胞有毒的寡聚物的形成。我们报告了含有抑制 hIAPP 纤维化的肽的脱氢苯丙氨酸 (DeltaF) 的设计、合成、3D 结构和功能表征。该抑制剂保护 β 细胞免受 hIAPP 诱导的毒性。
