Abstract:
Objective To investigate the acute effect of apolipoprotein E(apoE)on the intracellular free Ca2+ of rat cortical neurons.Methods The intracellular resting calcium level in cultured primary rat cortical neurons was measured by using confocal fluorescent imaging technique. MK-801,an N-methyl-D-aspartate (NMDA) receptor noncompetitive antagonist,was employed to test potential function of apoE4 through blocking NMDN receptor. ResultsAcute application of apoE4,but not apoE3,significantly increased the resting [Ca2+]i in a dose-and time-dependent manner (P
