AB Although it is presumed that the integration of HIV-1 into the genome of
infected CD4+ T lymphocytes allows viral persistence, there has been
little direct evidence that CD4+ T cells with integrated provirus
function as a latent reservoir for HIV-1 in infected individuals. Using
resting CD4+ T-cell populations of extremely high purity and a novel
assay that selectively and unambiguously detects integrated HIV-1, we
show that resting CD4+ T cells harbouring integrated provirus are
present in some infected individuals. However, these cells do not
accumulate within the circulating pool of resting CD4+ T cells in the
early stages of HIV-1 infection and do not accumulate even after
prolonged periods in long-term survivors of HIV-1 infection. These
results suggest that because of viral cytopathic effects and/or host
effector mechanisms, productively infected CD4+ T cells do not generally
survive for long enough to revert to a resting memory state in vivo.
