Lymphocytes Related to the Adaptive Immune Response
Three important types of cells are needed by the adaptive
immune system. These include two differ-ent types of lymphocytes, and the
antigen-presenting cells or APCs. The three types are summarized as follows:
■■ B lymphocytes control humoral immunity
■■ T lymphocytes make up the cellular arm of adaptive immunity; they
are non-antibody-producing lymphocytes
■■ Antigen-presenting cells perform auxiliary rolesinstead of
responding to specific antigens; however, these APCs are needed by T
lymphocytes to recognize their antigens TABLE 20-1 compares characteristics of T and B cells.
