To directly assess the putative re‐expression of MSR3 endogenous HLA‐I molecules in MSR3 G1m cells prior and after HCMV‐infection, two‐colour flow cytometry analysis was carried out combining HP‐1F7 and TP25.99, a mAb reported to specifically react with HLA‐A, ‐B, ‐C and ‐E molecules but not HLA‐G [53]. This evidence concerns the gene HLA-G and infection.
