| In vitro | Method: Transgenic and wild-type mice expressing tumor-associated self antigens were immunized with vaccines combined with a small-molecule CCR4 antagonist, and CD8⁺ T-cell responses and tumor growth were evaluated in prophylactic and therapeutic models. Result: The CCR4 antagonist combined with vaccination induced effector CD8⁺ T cells against self antigens and partially inhibited tumor growth, outperforming cyclophosphamide in eliciting anti-self CD8⁺ T-cell responses[1]. |
