CD4 and infection: Pre-exposure to α-CD169 nAb alone blocked virus capture (Figure 2G) and trans infection to autologous CD4+ T cells (Figure 2H) by immature and mature DCs, while α-DC-SIGN nAb alone had modest inhibitory effects in immature DCs and failed to block HIV-1 capture by mature DCs (Figure 2G and H), consistent with previously published results [11], [12], [13], [30].
