Recent progress in α-cell research has newly revealed its versatility including secretion of multiple hormones, trans-differentiation, and abundant proliferation. A recent report from the Kushner laboratory further provided direct evidence of active proliferation of α-cells in both T1D and non-diabetic control donors. α-cells are suggested to maintain both quality and quantity of islets by serving as 'guardians' of the islets.
近年来,α 细胞研究的进展揭示了其多功能性,包括分泌多种激素、转分化和丰富的增殖。最近 Kushner 实验室的一份报告进一步提供了直接证据,证明 T1D 和非糖尿病对照供体中的 α 细胞存在活跃增殖。α 细胞被认为通过充当胰岛的“守护者”来维持胰岛的质量和数量。
