Adoptive T cell transfer.

<p>Representative histogram of CD8⁺ T cells homing-into the spleen of a recipient mouse 48 hours after cell transfer, before arterial injury (A). Viable lymphocytes were gated on the FSC/SSC plot. Representative sections of 21-day injured carotid arteries (400× magnification) stained with hematoxylin and eosin from Rag-1−/− mice (B), Rag-1−/− injected with CD8⁺ T cells (D), and Rag-1−/− mice injected with CD4⁺ T cells (F). Boxed area indicates magnification of the respective cross-sections (C, E, G). Arrows indicate internal elastic lamina. Bar = 50 microns.
