T cell activation is triggered when the T cell receptor binds to an antigen displayed on another cell's MHC. This leads to the release of cytokines and the activation and differentiation of T cells.
T cell activation is initiated when the T cell receptor recognizes an antigen presented on an MHC of another cell. This interaction triggers a series of events, including the release of cytokines that contribute to T cell activation and differentiation. The process involves specific recognition of foreign epitopes presented within the MHC II antigen-binding cleft on antigen-presenting cells.
