MHC class II expression on inflamed vessels. Three weeks after adoptive transfer, eye cryosections were prepared and stained for MHC class II (green), IBA1 (red) or GFAP (red), and CD31 (magenta) detection. Cell nuclei were stained with Hoechst (blue). Each picture was chosen as representative of an experiment conducted on three or more animals. a MHC class II and IBA1 expression at the level of vasculitis. b MHC class II, CD31, and GFAP expression at the level of vasculitis
