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 ...

WebJul 18, 2024 · The balance of anti- and pro-cancer activity is influenced by the particularly delicate interplay that exists between neutrophils and T lymphocytes. In murine models, it has been reported that γδ T cells are a major source of IL-17 that drives the recruitment and pro-tumorigenic differentiation of neutrophils. WebCancer vaccines designed to augment effector T-cell responses have been disappointing with respect to clinical efficacy. This lack of effectiveness may be due to the fact that regulatory mechanisms, both intrinsic and extrinsic to activated T cells, play important roles in inhibiting vaccine-induced effector T-cell responses.
