Regardless, our findings that the reduction of CD8+CD122+ regulatory T cells correlated with the increase in CD8+ T cells (as well as the changes in IL-10, IFN-γ, and CXCR3) suggest that CD8+CXCR3+ regulatory T cells could alleviate ALI injury through stimulate the release of IL-10, inhibiting the production of IFN-γ, and inhibiting CXCR3 release. Here, IFNG is linked to acute respiratory distress syndrome.
