S1A Fig depicts the increase in p24 production by HIV-C, HIV*Vpx and HIV*Vpx-C, while non-opsonized HIV showed a low replication in DCs over time (S1A Fig). Increased infection of DCs by HIV-C was furthermore confirmed by p24 ELISA in blood BDCA-1+ DCs (S1B Fig). The gene discussed is CD1C; the disease is infection.
