WebApr 1, 2009 · Abstract. Dendritic cells (DC) have a critical effect on the outcome of adaptive immune responses against growing tumors. Whereas it is generally assumed that the presence of phenotypically mature DCs should promote protective antitumor immunity, evidence to the contrary does exist. We describe here a novel mechanism by which … WebBlocking CTLA-4 may render T cells more responsive to antigen (by lowering the activation threshold), and/or it may inhibit or deplete regulatory T cells (Tregs) [6,7]. Since Tregs can potently suppress the function of antigen-presenting cells (APCs) in the tumor microenvironment [ 8 , 9 ], CTLA-4 antibody might thus enhance functional cross ...
