摘要:

为了揭示胰岛炎症导致2型糖尿病发生发展的机制, 建立胰岛β细胞和巨噬细胞相互作用的数学模型, 包括IL-1β的产生和巨噬细胞的浸润过程, 研究高浓度葡萄糖和游离脂肪酸对IL-1β的共同作用, 揭示胰岛炎症在2型糖尿病进程中的动力学机理。通过对模型中动力学参数的敏感性分析, 提出针对不同患病情况的可能的优化治疗策略。

关键词: 2型糖尿病, 胰岛炎症, 动力学模型, 巨噬细胞浸润, IL-1β

Abstract:

In order to reveal the pathogenesis of type 2 diabetes caused by inflammation in islets, this paper established the mathematical model of interaction between β cell and macrophage, including the process of IL-1β production and macrophage infiltration in islets. The combined effects of glucose and free fatty acid on IL-1β was analyzed to reveal the dynamic mechanism of islet inflammation in the progression of type 2 diabetes. By analyzing this model’s sensitivity to parameters variation, the feasible optimal treatment strategies was given to different type 2 diabetes patients.

Key words: type 2 diabetes, islets inflammation, dynamic model, macrophage infiltration, IL-1β
