These included serum concentrations of IL-15 and IL-7 that may cause reduced CD127 expression [28], sCD14 and LPS, which are reflective of microbial translocation and immune activation [29], MDA adducts, which are products of lipid peroxidation due to oxidative stress [30], and IL-6, a marker associated with development of opportunistic infections and all-cause mortality in HIV disease [31]. Here, IL7 is linked to Opportunistic infection.
