title: Decreased recovery of replication-competent HIV-1 from peripheral blood mononuclear cell-derived monocyte/macrophages of HIV-positive patients after 3 years on highly active antiretroviral therapy.
abstract: We studied the release of p24 antigen from peripheral blood mononuclear cell-derived monocyte/macrophages obtained from 13 HIV-positive patients receiving highly active antiretroviral therapy (HAART). Although HIV-infected monocyte/macrophages were detected in 80% of patients after 36 months of continuous treatment, additional exposure to HAART reduced the chance of detecting HIV-releasing monocyte/macrophages. Therefore, after more than 3 years of HAART, recently infected monocytes may play a less important role as a source of emerging HIV-1 upon HAART interruption.
