abstract = {Gastrointestinal infections are a major cause for serious
clinical complications in infants. The induction of antibody
responses by B cells is critical for protective immunity
against infections and requires CXCR5+PD-1++ CD4+ T cells
(TFH cells). We investigated the ontogeny of CXCR5+PD-1++
CD4+ T cells in human intestines. While CXCR5+PD-1++ CD4+ T
cells were absent in fetal intestines, CXCR5+PD-1++ CD4+ T
cells increased after birth and were abundant in infant
intestines, resulting in significant higher numbers compared
to adults. These findings were supported by scRNAseq
analyses, showing increased frequencies of CD4+ T cells with
a TFH gene signature in infant intestines compared to blood.
Co-cultures of autologous infant intestinal
CXCR5+PD-1+/−CD4+ T cells with B cells further
demonstrated that infant intestinal TFH cells were able to
effectively promote class switching and antibody production
by B cells. Taken together, we demonstrate that functional
TFH cells are numerous in infant intestines, making them a
promising target for oral pediatric vaccine strategies.},
