plasma cells

**plasma cells**

Plasma cells are specialized white blood cells that play a crucial role in the immune system by producing antibodies. Originating from B lymphocytes, plasma cells are responsible for identifying and neutralizing pathogens such as bacteria and viruses. They are primarily found in the bone marrow, spleen, and lymph nodes, where they secrete large quantities of antibodies to help the body fight infections and provide long-lasting immunity. Understanding plasma cells is essential in fields like immunology, hematology, and medical research, particularly for conditions involving immune responses, autoimmune diseases, and certain cancers like multiple myeloma.
