What kind of lymphocytes are formed and mature in the bone marrow?

B-cells are a type of lymphocyte that are specifically formed and mature in the bone marrow. This process is crucial as B-cells play a fundamental role in the adaptive immune response. Once matured, B-cells can differentiate into plasma cells that produce antibodies, which are essential for identifying and neutralizing pathogens like bacteria and viruses.

During the immune response, B-cells circulate in the bloodstream and lymphatic system, ready to encounter antigens. Their ability to produce antibodies is key to providing long-term immunity and facilitating the process of memory formation after an infection. This maturation process in the bone marrow distinguishes B-cells from T-cells, which originate in the bone marrow but mature in the thymus.
