Germinal center reaction

The germinal center reaction is a key part of the immune response where specialized structures within lymph nodes, called germinal centers, help produce high-quality antibodies. When infection occurs, B cells (a type of immune cell) are activated and move into these centers, where they rapidly divide and mutate their antibody genes. This process refines their ability to recognize the pathogen more effectively. Some of these B cells then become long-lasting memory cells or produce potent antibodies, helping the body remember and fight future infections more efficiently.
