1引言糖尿病根据发病机制的不同分为1型糖尿病和2型糖尿病,而1型糖尿病是一种慢性自身免疫性疾病,胰岛的β细胞破坏,使胰岛素绝对缺乏,产生一系列代谢障碍,最终导致疾病的产生[1]。胰岛素对于绝大多数患者均有效,然而,1型糖尿病患者有发生低血糖的风险,甚至可能危及生命。目前,胰岛细胞移植是糖尿病治疗的研究热点,也是最有希望能够治愈糖尿病的一种方法。本文将就重点讲述 1 Introduction Diabetes mellitus is divided into type 1 diabetes and type 2 diabetes according to the pathogenesis. Type 1 diabetes is a chronic autoimmune disease. The destruction of islet beta cells causes an absolute lack of insulin and produces a series of metabolic disorders that eventually lead to Disease generation [1]. Insulin is effective in the vast majority of patients, however, people with type 1 diabetes are at risk of developing hypoglycemia and may even be life-threatening. Currently, islet cell transplantation is a hot research topic in the treatment of diabetes and one of the most promising ways to cure diabetes. This article will focus on
