Two-color histograms at day 6 evaluating recruitment of CD8⁺ T cells to the kidney, liver, lung and spleen.

Analysis of the proportion of CD8⁺ T cells in the kidney, liver, lung, and spleen at day 6 after transfer of MIP-1α^−/− or MIP-1α^+/+ T cells. Significant differences were noted in the number of CD8⁺ T cells in the liver, lung, and spleen (P < .001 for both; Table 1) as a function of T-cell production of MIP-1α. Due to the significant expression of eGFP in the donor cells, the population of CD8-expressing cells has been shifted down on the y axis, resulting in the majority of cells not expressing CD8 falling below the y axis.
