Publication date: 1 January 2018 Source:Neuroscience Letters, Volume 662 Author(s): Shan Tian, Fengping Zhu, Ruiping Hu, Song Tian, Xingxing Chen, Dan Lou, Bing Cao, Qiulei Chen, Bai Li, Fang Li, Yulong Bai, Yi Wu, Yulian Zhu Exercise preconditioning is a simple and effective way to prevent ischemia. This paper further provided the mechanism in hemodynamic aspects at the cellular level. To study the anti-apoptotic effects of fluid mechanics preconditioning, Cultured rats brain microvascular endothelial cells were given fluid intervention in a parallel plate flow chamber before oxygen glucose deprivation. It showed that fluid mechanics preconditioning could inhibit the apoptosis of endothelial cells, and this process might be mediated by the shear stress activation of Tie-2 on cells membrane surface and Bcl-2 on the mitochondria surface.
