Destabilization of intratumor Tregs by CTLA-4 engagement confers anti-CTLA-4-driven immunotherapy
It is shown that anti-CTLA-4 antibody engages CTLA-4 in Tregs specifically in the tumor tissues to reduce their stability and survival and weaken their suppressive function through upregulating TGF-β signaling, which leads to the antibody-mediated - upregulation of CD4+ and CD8+ effector T cell anti-tumor immunity and...
