	1	CXCR5^(+)PD-1^(++)CD4^(+)T cells colonize infant intestines early in life and promote B cell maturation显示文摘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.
