CD4 and infection: Even though the levels of proliferation on productively infected CD4+ T cells (eGFP+) were not consistently reduced (no significant changes) in the multiple-round infection, we found extended degrees of inhibition on productively infected CD4+ T cells (eGFP+) in the single cycle setting (p = 0.0027; S2B Fig and p = 0.0156; S2C Fig).
