WebFeb 18, 2024 · These cells include B cells, which produce antibodies needed to fight infection; cytotoxic T cells, which kill cells carrying infectious agents; and macrophages … WebFigure 18.22 In T cell-dependent activation of B cells, the B cell recognizes and internalizes an antigen and presents it to a helper T cell that is specific to the same antigen. The helper T cell interacts with the antigen presented by the B cell, which activates the T cell and stimulates the release of cytokines that then activate the B cell.
