Concept explainers
Lymphocytes are types of white blood cells (WBCs) and they include B cells, T cells, and natural killer cells. Lymphocytes play a crucial role in the immune system of the body. B-cell precursors are produced from the stem cells in the bone marrow. Subsets of B cells contain a unique function, they are involved in the immune mechanism and antibody production. B cells regulate antibody or humoral immune system. Toll-like receptors are present on the B-cells and they regulate activation of B-cells throughout the developmental stages of B cells. The subset of B-cells has a well-defined activation mechanism. B cells are activated by a specific antigen, which is required for their proliferation, differentiation, and maturation.
