T cells

T cells are a type of white blood cell that play a crucial role in the immune system. They help protect the body against infections and diseases, including cancer. T cells recognize and attack foreign invaders, such as viruses and bacteria, through a specialized process. There are various types of T cells, including helper T cells, which assist other immune cells, and cytotoxic T cells, which directly kill infected or cancerous cells. By recognizing specific antigens, T cells help the body mount a targeted immune response, contributing to overall health and disease defense.
