Plasma Cells: The Immune System's Antibody Factories

Plasma cells are the immune antibody factories. They are a type of white blood cell that are produced in the bone marrow and mature in the lymph nodes. Plasma cells produce antibodies, which are proteins that help the body fight infection. Antibodies bind to antigens, which are molecules that are found on the surface of bacteria, viruses, and other foreign substances. This binding helps the body to recognize and destroy the foreign substances.

Plasma cells are a critical part of the immune system. They help the body to protect itself from infection and disease.
