Exposure to HIV is associated with altered composition of maternal microchimeric T cells in infants. | LitMetric

AI Article Synopsis

Article Abstract

HIV exposed but uninfected infants (iHEU) display altered immunity and are at increased risk of infection. We previously reported that iHEU have decreased maternal microchimerism (MMc)-maternal cells transferred to the offspring in utero/during breastfeeding. We quantified MMc in T cell subpopulations in iHEU and unexposed infants (iHU) to determine whether a selective deficiency in MMc contributes to altered cellular immunity. Across all infants, MMc levels were highest in CD8+ T cells; however, the level of CD8+ T cell MMc was lower in iHEU versus iHU. In limited functional studies, we did not identify CMV-specific MMc during infant primary infection.
