WebNov 1, 2024 · The first mechanism of ADE is dependent on FcR (Figure 1 A).FcRs are mainly distributed on immune cells and are receptors targeting the Fc portions on antibodies (Dustin, 2016).In this FcR-mediated ADE, the viral surface protein combines with the antibody to form a virus–antibody complex. WebOct 19, 2024 · The authors used maternal and cord blood sera or breast milk to measure anti-SARS-CoV-2 antibody titers, glycosylation patterns, FcR binding, and FcR-mediated antibody functions. They also used placental biospecimens to characterize gene expression and cytokine release in the placenta of women infected with SARS-CoV-2.
