Absolute counts of CD4+ (r = −0.71; p<0.01) and CD8+ T cells (r = −0.65; p<0.05) were negatively correlated with LPS (Figure 2C and 2D), showing that the lower T subset numbers were associated with the highest LPS levels during the active phase of leishmaniasis, whereas during clinical remission, the inverse was observed, i.e., the higher T CD4+ counts were associated with the lowest LPS levels. This evidence concerns the gene CD4 and leishmaniasis.
