At baseline, there was no difference between INRs and IRs, but CD261 expression on MICA/B+CD4+ T cells tended to increase with prolonged infection and was higher in IRs than in INRs at the 4-year post-ART time point (IR-ART vs. INR-ART, P = 0.0117; Figure 3B). This evidence concerns the gene CD4 and infection.
