Research Article: Gut microbiota and other factors associated with increased T cell regulation in HIV-exposed uninfected infants

Date Published: 2025-03-03

Abstract:
Introduction: Infants exposed to HIV and uninfected (HEUs) are at higher risk of infectious morbidity than HIV-unexposed uninfected infants (HUUs). Multiple immune defects of unknown origin were observed in HEUs. We hypothesized that HEUs have more regulatory and inhibitory checkpoint-expressing T cells (Treg, Tici) than HUUs, which may dampen their immune defenses against pathogens.
