Germinal center
A germinal center is a specific area within lymph nodes where immune cells, particularly B cells, undergo crucial processes in response to an infection. When the body detects a pathogen, these centers form to help B cells rapidly multiply and improve their ability to produce antibodies. Within germinal centers, B cells can undergo mutations to refine their antibody responses, enhancing their effectiveness. This process is vital for developing long-lasting immunity, helping the body remember past infections and respond more efficiently to future ones. Essentially, germinal centers are key sites for the maturation and adaptation of the immune response.
