Children with acute RV-gastroenteritis (GE) had low or undetectable levels of circulating IFN-gamma(+), IL-13(+), IL-2(+), IL-10(+) or IL-17(+) RV-T cells. IFN-gamma(+) T cells and low frequencies of IL-10(+) and IL-2(+) CD4(+) T cells were found in adults with RV-GE during acute and convalescence phases, respectively. Circulating single IFN-gamma(+)>double IFN-gamma(+)/IL-2(+)>single IL-2(+)RV-CD4(+)T cells were observed in healthy adults. In this group, frequencies of IFN-gamma(+) RV-T cells increased after removing CD25(+)cells, blocking TGF-beta with its natural inhibitor, LAP, or inhibiting TGF-betaRI signalling pathway with ALK5i. The frequencies of IFN-gamma(+) RV-T cells were also incremented in PBMC depleted of CD25(+)cells and treated with ALK5i, suggesting that TGFbeta inhibition may be independent of Treg cells. The ALK5i effect was observed in adults but not in children with RV-GE, who had normal numbers of TGF-beta+ Treg cells. Thus, a TGF-beta-mediated regulatory mechanism that modulates RV-T cells in adults is not evident in children.
