朗格汉斯岛是分散在胰腺各处的内分泌细胞岛。许多新研究指出,将非 β 胰岛细胞转化为产生胰岛素的 β 细胞以补充 β 细胞质量作为治疗糖尿病的一种方法具有潜力。了解正常的胰岛细胞质量和功能对于帮助推进此类治疗方式非常重要:目标胰岛/β细胞质量应该是什么,胰岛结构对能量稳态是否重要,以及如果我们失去特定的胰岛细胞群而转而使用β细胞,会发生什么?这些都是我们需要解答的问题,以便通过非β胰岛细胞转分化的胰岛替代疗法在人类中成为现实。我们对 β 细胞的生物学了解相当多,但对其他胰岛细胞类型却知之甚少。直到最近,我们还没有很好地掌握人类胰腺中的胰岛质量和分布。在这篇综述中,我们将研究胰岛细胞的当前数据,更多地关注非 β 细胞以及人类胰岛的质量和分布。
Islets of Langerhans are islands of endocrine cells scattered throughout the pancreas. A number of new studies have pointed to the potential for conversion of non-β islet cells in to insulin-producing β-cells to replenish β-cell mass as a means to treat diabetes. Understanding normal islet cell mass and function is important to help advance such treatment modalities: what should be the target islet/β-cell mass, does islet architecture matter to energy homeostasis, and what may happen if we lose a particular population of islet cells in favour of β-cells? These are all questions to which we will need answers for islet replacement therapy by transdifferentiation of non-β islet cells to be a reality in humans. We know a fair amount about the biology of β-cells but not quite as much about the other islet cell types. Until recently, we have not had a good grasp of islet mass and distribution in the human pancreas. In this review, we will look at current data on islet cells, focussing more on non-β cells, and on human pancreatic islet mass and distribution.
