To assess the contribution of antibodies targeting different HCMV envelope glycoproteins to neutralization, sera from five seropositive subjects were incubated with purified Pentamer, gH/gL44, or postfusion gB (gB-698glyco) and the corresponding antibody-depleted sera were evaluated for neutralization of epithelial cell and fibroblast infection (Table 4). Here, ERVW-1 is linked to infection.
