Abstract:Estrogens are effective neuroprotectants in vivo and in vitro. To obtain a better insight into the molecular mechanisms of action of neuroprotection by 17β-estradiol (E2), we examined the differential effects of E2 on the fluidity of synaptosomal plasma membrane vesicles (SPMV) isolated from rat cerebral cortex. Intramolecular excimerization of 1,3-di(1-pyrenyl)-propane (Py-3-Py) was used to investigate the effects of E2 on the bulk and annular lateral diffusion of the SPMV. In addition, we examined the effect… Show more
