Our objective was to evaluate the in vitro functional profile of T cells from uninfected neonates born from HIV-1-infected pregnant women who controlled (G1) or not (G2) the virus replication. We demonstrated that the lymphoproliferation of T cell to polyclonal activators was higher in the G2 as compared with G1. Nevertheless, no detectable proliferative response was observed in response to HIV-1 antigens in both neonate groups. Cytokine dosage in the supernatants of these polyclonally activated T cell cultures demonstrated that, while IL-10 was the dominant cytokine produced in G1, Th17-related cytokines were significantly higher in G2 neonates. The higher Th17 phenotype tendency in G2 was related to high production of IL-23 by lipopolysaccharide-activated monocyte-derived dendritic cells from these neonates. Our results demonstrated immunological disorders in uninfected neonates born from viremic HIV-1-infected mothers that can help to explain why some of these children have elevated risk of clinical morbidity and mortality due to pathological hypersensitivity.
