Popis: B7x is a B7-family ligand with suppressive effects on effector T cells. Here the authors show that tumor-expressed B7x promotes the conversion of conventional CD4+ T cells into regulatory T cells within the tumor microenvironment to promote immune evasion and resistance to anti-CTLA-4 therapy.
