The differentiation of naive T cells to immune suppressing induced regulatory T (iTreg) cells requires TGF-beta-1 and downregulation of mTORC1 activity, which inhibits mRNA translation. Here the authors show that iTreg cell differentiation uses an alternate mRNA translation mechanism involving translation factors DAP5 and eIF3d.
