T-helper cells

T helper cells are a type of white blood cell that play a crucial role in the immune system. Their main job is to help other immune cells recognize and respond to infections, such as bacteria and viruses. They do this by releasing signaling molecules called cytokines, which coordinate the activity of various immune cells, including B cells that produce antibodies and killer T cells that destroy infected cells. By facilitating these responses, T helper cells are essential for creating an effective immune response and maintaining overall health.
