We investigated whether CD4 + T cells that do not produce HIV-1 are killed in HIV-infected human lymphoid tissue. Tissue blocks were inoculated with high amount of doxycycline-dependent HIV-rtTA. Doxycycline triggered productive infection and loss of CD4 + T cells in these tissues, whereas without doxycycline, neither productive infection nor CD4 + T cell depletion was detected in spite of the massive presence of virions in the tissue and of viral DNA in the cells. Thus, HIV-1 alone is sufficient to deplete productively infected CD4 + T cells but is not sufficient to cause the death of uninfected or latently infected CD4 + T cells.
