Browsing: T-cells

T-cells, or T lymphocytes, are a type of white blood cell that play a central role in the immune response and are essential for adaptive immunity. They are produced in the bone marrow and mature in the thymus, which is where they derive their name. T-cells are distinguished by their T-cell receptors that allow them to recognize and bind to specific antigens presented by other cells. There are several types of T-cells, including helper T-cells, which assist other immune cells; cytotoxic T-cells, which kill virus-infected cells and cancer cells; and regulatory T-cells, which help maintain immune tolerance and prevent autoimmune diseases. Their ability to target specific antigens makes T-cells crucial in the body’s defense against pathogens, in tumor suppression, and in the overall regulation of the immune system.
