plasma cells

Plasma cells are a type of white blood cell that play a crucial role in the immune system. They develop from B cells when the body encounters an infection or foreign substance, such as bacteria or viruses. Plasma cells produce antibodies, which are proteins that specifically target and neutralize these invaders. By generating large amounts of antibodies, plasma cells help protect the body from diseases and infections. Once the invader is eliminated, some plasma cells become long-lived memory cells, ensuring that the immune system can respond more quickly if the same threat appears again.
