AB Mature Langerhans cells (mLC), the ex vivo correlates of interdigitating
dendritic cells (IDC), are susceptible to infection with HIV-1. As IDC
are important activators of T helper (Th) cells in vivo, we examined the
interaction of HIV-1-infected mLC with CD4+ T lymphocytes.
HIV-1-infected mLC readily formed clusters with the T cells and
efficiently transmitted HIV-1 to the CD4+ Th cells. Formation of
syncytia between mLC and T cells was initiated by HIV-1-infected mLC. In
the clusters of HIV-1-infected mLC and activated T cells a massive HIV-1
production was observed leading to the subsequent elimination of the
activated and infected T helper cells. Examination of the cytokine
pattern produced during interaction of infected mLC with CD4+ T cells
revealed an enhanced production of IFN-gamma and IL-10 in the
cocultures. These results suggest that during antigen
presentation-driven T cell activation by IDC in the lymphoid tissues,
HIV-1-infected IDC might efficiently transmit the virus to Th cells,
leading to altered Th cell responses.
