Qa-1 is the mouse homologue of human HLA-E that can present self as well as microbial antigens . In addition, non-Qa-1-restricted CD8 + CD28 − Tregs that suppress via antigen-presenting cells have been described (21, 22).
WebA significant loss of CD8+ Tregs was seen in Tgfβr2-/- Eomes-/- mice. Adoptive transfer of wild type CD8+ Tregs to Tgfβr2-/- Eomes-/- mice largely rescued the defective germinal center reaction, suggesting intrinsic defects in Tgfβr2-/- Eomes-/- CD8+ Tregs, and that other T cell subsets are not responsible for the observed phenotype.
