alpha-beta T cells

Alpha-beta T cells are a type of immune cell that plays a crucial role in defending the body against infections. They have receptors called T-cell receptors (TCRs) made of alpha and beta chains, which help them recognize specific pieces of pathogens presented by other cells. These cells can directly attack infected cells or help coordinate the immune response by activating other immune cells. They are a major component of the adaptive immune system, providing targeted, long-lasting immunity. Their ability to identify and respond to specific threats makes them vital for protecting the body from a wide range of infectious agents.
