IVIg promotes endothelial cell survival in OGD . (A) IVIg treatment reduced LDH release from bEnd.3 cells subjected to 1–3 h OGD. *** p < 0.001 as indicated by bars. (B and C) IVIg moderated the increase in AIF levels in bEnd.3 cells, however statistical significance was not reached. (D, E and F) IVIg prevented the decrease in Bcl-2 and Bcl-XL levels measured in bEnd.3 lysates following 3 h OGD. *** p < 0.001, * p < 0.05 as indicated by bars.
