Mature B cells

Mature B cells are a type of white blood cell that plays a key role in the immune system by producing antibodies. These cells develop in the bone marrow and, once mature, circulate in the blood and lymphatic system, ready to recognize specific threats like bacteria or viruses. When they encounter their target, mature B cells quickly multiply and produce antibodies tailored to attack or neutralize the invader. This process helps the body defend itself and remember the threat for future protection. Mature B cells are essential for long-term immunity and overall immune health.
