HLA-G and infection: Indeed, we found a significant inverse correlation between HLA-G expression on B-LCLs and IFN-γ production by MAITs, and a direct correlation between HLA-G expression and the level of infection (CSA) on B-LCLs, but no correlation between CSA expression on B-LCLs and IFN-γ production by MAITs (Figure 3C).
