rhEPO inhibits migration of CD4+ and CD8+ T cells to the brains of P. berghei ANKA-infected mice. At 5 days p.i., three mice from each of the three groups (uninfected, P. berghei ANKA, and P. berghei ANKA plus EPO) were processed for the quantification of CD4+ and CD8+ T cells in the brains. The values are means and SEM (n = 3). * and **, significant differences at P values of <0.05 and <0.01 (t test) between treatment groups, respectively.
