摘要: HIV-1 Nef enhances dendritic cell (DC)-mediated viral transmission to CD4+ T cells, but the underlying mechanism is not fully understood. It also unknown whether infected DCs play a role in activating cells and enhancing DC-mediated transmission. Here we investigated of infection primary using wild-type Nef-mutated viruses. We show that facilitated activated cells. expressing enhanced activation proliferation resting However, when co-cultured with HIV-1-infected autologous DCs, there was no significant trend for infection- or Nef-dependent Our results suggest an important which likely contribute pathogenesis.
