Aβ1-42作用的小胶质细胞对体外培养的神经干细胞生存的影响
Effects of Aβ1-42-induced microglial cells on survival of neural stem cells in vitro
摘要
Abstract
AIM: To explore the effects of β-amyloid protein 1-42 (Aβ2-42) -induced microglia on the survival of cultured neural stem cells ( NSCs) in vitro. METHODS: Using the Transwell chambers to build a coculture system of NSCs and microglia , we detected the proliferation , differentiation and apoptosis of the NSCs with the microglia before and after induction by Aβ-42. RESULTS; Compared with non - intervention group , the proliferation rate of NSCs in Aβ1-42 intervention coculture group decreased , as well as the positive expression rates of microtubule - associated protein 2 ( MAP -2) and choline acetyltransferase. CONCLUSION; The inflammation mediated by Aβ1-42 inhib their the proliferation of NSCs and induces their apoptosis . Inflammation also significantly reduces the ratio of NSCs differentiating to neu -rons, especially to cholinergic neurons .关键词
