The panel was chosen to follow the expression of markers of interest in HIV-1 infection (CXCR4), to study neutrophil activation (CD11b, CD66b, etc), immunosuppressive functions (PD-L1/PD-1), maturity (CD10) and Fc receptors (FcRs, CD16, CD32, CD64 and CD89), among others. Here, ITGAM is linked to HIV-1 infection.
