WebThe cells produced by the adaptive immune system include antibody-secreting B cells and cytotoxic T cells. The antibodies (called immunoglobulin, or Ig) secreted by the B cells... WebCytotoxic T cells destroy virus-infected cells in the cell-mediated immune response, and helper T cells play a part in activating both the antibody and the cell-mediated immune responses. Suppressor T cells deactivate T cells and B cells when needed, and thus prevent the immune response from becoming too intense.
WebFeb 29, 2016 · Upon activation of both cells, they change expression of their chemokine receptors allowing them to migrate towards each other and interact. The B cell then, as an APC, presents the antigen to the effector helper T cell. Helper T cells activate B cells to proliferate and differentiate - not the other way around :) WebCytotoxic T cells (T C) are the key component of the cell-mediated part of the adaptive immune system and attack and destroy infected cells. T C cells are particularly important in protecting against viral infections; this is because viruses replicate within cells where they are shielded from extracellular contact with circulating antibodies.
WebCytotoxic T cells attempt to identify and destroy infected cells before the pathogen can replicate and escape, thereby halting the progression of intracellular infections. They also support NK lymphocytes to destroy early cancers.
