Can t cells activate b cells
WebThe T cell then binds using its antigen receptor and is activated to secrete cytokines that diffuse to the B cell, finally activating it completely. Thus, the B cell receives signals from both its surface antibody and the T cell via its cytokines, and acts as a professional antigen-presenting cell in the process. WebWhen an effector B cell (plasma cell) becomes activated it produces memory and effector B cells. A memory B cell lasts for a long time so if in the future the pathogen comes back it can proliferate effector and memory cells. A effector B cell on the other hand …

WebLike T cells, B cells possess antigen-specific receptors with diverse specificities. Although they rely on T cells for optimum function, B cells can be activated without help from T cells. B-cell receptors (BCRs) for naïve mature B cells are membrane-bound monomeric forms of IgD and IgM. birthday scratch off gamesWebA cytotoxic T cell will bind only to cells with an MHC 1 that is presenting the specific antigen that the cytotoxic T cell is supposed to bind to. So if a B-cell's MHC 1 is presenting the right antigen then the cytotoxic T cell will bind and kill it. This would only usually happen if the B-cell is infected. ( 7 votes) Show more...
