Extent of cell cycling in virus-specific CD8⁺ T cells during and after resolution of AIM.

PBMCs were isolated from patients before (acute) and after (chronic) the resolution of AIM. These cells were stained by 4-color flow cytometry for CD8, latent or lytic HLA class 1 tetramers, CD45RA, and the cell cycle marker Ki67. Representative results from 1 of 3 similar experiments are shown.
