摘要:

1型糖尿病是一种由于自体免疫细胞破坏分泌胰岛素的β细胞而引起胰岛素绝对缺乏的自体免疫病。疾病患者需要依靠外源性途径来补给胰岛素, 但胰岛素注射治疗不能根治病症, 也不能有效地预防糖尿病并发症。多能性干细胞以及体细胞重编程产生胰岛素分泌细胞为根治1型糖尿病提供了可能。编程性的细胞能被用来进行移植治疗和药物筛选, 为1型糖尿病的治疗带来了新的希望。当前, 通过相关转录调节因子重编程终末分化细胞为胰岛β细胞已经取得了很大进展。文章对胰腺早期发育、胰腺相关转录调控因子及目前利用终末分化细胞重编程产生胰岛β细胞的研究内容进行了综述。

Abstract:

Type 1 diabetes mellitus (T1DM) is an autoimmune disease in which the immune system attacks insulin-secreting β cells, thus leading to an absolute deficiency of insulin. Patients must rely on exogenous insulin, which cannot effectively prevent diabetes complications. Generation of insulin-secreting cells by reprogramming of pluripotent stem cells or somatic cells is a potential approach for the treatment of T1DM. These cells can be used for cell therapy and drug screening, and may eventually provide a cure for the disease. Significant progress has been made in generating insulin-secreting cells through the expression of β cell specific transcription factors in stem cells or somatic cells. In this review, we summarize recent research progress in early pancreas development, β cell specific transcription factors and reprogramming of terminally differentiated cells into β cells.
