t Cells
T cells are a type of white blood cell and are a major component of the human immune system. They are responsible for defending the body against infection and disease. T cells recognize and respond to foreign pathogens and other dangerous substances in the body, and play a key role in the body's response to infection and the development of immunity. They are also able to recognize and respond to self-antigens (our own proteins, for example), which is important for the prevention of autoimmune diseases. T cells have several different types, all of which have different roles and functions. The different types of T cells work together to identify and respond to foreign invaders, helping the body to fight off infection and disease.
