ALPHA BETA T CELL RECEPTOR Meaning and
Definition
-
The alpha beta T cell receptor is a protein complex found on the surface of T cells, a type of white blood cell that plays a critical role in the immune system. T cells are responsible for recognizing and attacking foreign pathogens, such as bacteria, viruses, and cancer cells. The alpha beta T cell receptor is part of the T cell receptor family and is the most common type found in humans.
The protein complex consists of two different chains, namely the alpha chain and the beta chain, which are encoded by specific genes. These chains are arranged in a specific way, forming a structure that binds to antigens, or foreign substances, allowing the T cell to recognize and respond to the presence of these antigens.
The alpha beta T cell receptor is highly diverse, meaning that it can recognize a wide range of antigens. This diversity is due to the process of gene rearrangement, in which specific gene segments are randomly combined during T cell development. This process generates unique receptors with varying antigen-binding regions. The ability of the alpha beta T cell receptor to recognize a diverse repertoire of antigens is essential for an effective immune response.
Upon binding to antigens, the alpha beta T cell receptor triggers a cascade of signaling events inside the T cell, leading to the activation and proliferation of T cells, as well as the production of immune mediators, such as cytokines. This immune response is crucial for eliminating pathogens from the body and maintaining overall health and immunity.
