18.4 B Lymphocytes and Humoral Immunity - OpenStax

WebAcquired (adaptive or specific) immunity is not present at birth. It is learned. The learning process starts when a person’s immune system encounters foreign invaders and recognizes nonself substances (antigens). Then, the components of acquired immunity learn the best way to attack each antigen and begin to develop a memory for that antigen. WebAs B and T cells mature into effector cells, a subset of the naïve populations differentiates into B and T memory cells with the same antigen specificities (Figure 17.17). A memory cell is an antigen-specific B or T lymphocyte that does not differentiate into an effector cell during the primary immune response, but that can immediately become an effector cell … fkw.lolzhushen.top

WebImmunity refers to the ability of your immune system to defend against infection and disease. There are two types of immunity that the adaptive immune system provides, and they are dependent on the functions of B and T cells, as described above. Humoral immunity is immunity from serum antibodies produced by plasma cells. WebWe have been investigating T lymphocyte interactions in the development of effector lymphocytes in a cell-mediated immune res ponse (1-3).

WebLymphocytes are a type of immune cell. There are two main types of lymphocytes: T lymphocytes (T cells): T cells control your body’s immune system response and directly attack and kill infected cells and tumor cells.
