Web3 de jun. de 2024 · Other plasma cells, plasmablasts, are generated in T-dependent germinal centre responses. They enter the circulation and home to the bone marrow where they differentiate into long-living plasma cells. Plasma cells in the bone marrow continue to secrete antibodies for months or even years after the antigen is no longer present. Web5. Some mature neurons can last a lifetime. Gastrointestinal cells such as those in the colon might be shortest-lived, and skin may give them a run for their money. However, depending on how you define lifespan, egg and sperm cells could beat those numbers. Also, some immune cells only last a few days under certain scenarios, such as the aptly ...
