Genes differentially expressed by CD4 and CD8 cells upon in vitro exposure to rIL-2 (300 IU/ml) independent of the presence or absence of the rest of the PBMC population. In spite of significance in expression in all populations compared with baseline conditions, clusters could be identified with preferential expression according to the in vitro condition in which rIL-2 was administered. In blue are clusters of genes up regulated by rIL-2 (main clusters a, b and c) and in maroon those down regulated (clusters d and e).
