Consistent with OVA-specific CD8 T cells, LLO-specific effector CD4 T cells expressed high levels of glycosylated CD43 that declined through day 28 post infection with no difference in the expression level on LLO-specific CD4 T cells in either WT or E-FABP-/- mice (Fig 4A and 4B). The gene discussed is CD8A; the disease is infection.
