Fig 4. Selectin ligand induction in response to inflammatory cytokines requires p38 alpha.
CD4 cells were isolated from p38α cKO mice or their cre-negative littermates and cultured with the six cytokines or IL-2 alone as above. FACS analysis was performed every two days. Values are mean ± SD for n=3. *p<0.01 vs cre-negative cells.
