T-cell receptors are proteins found on the surface of T-cells, which are a type of white blood cell that plays a crucial role in the immune system. They are responsible for recognizing and binding to specific antigens (foreign substances) found on the surface of infected or abnormal cells.
T-cell receptors and antibodies are both part of the immune system, but they play different roles. T-cell receptors are found on the surface of T-cells and are responsible for recognizing and binding to specific antigens, while antibodies are produced by B-cells and are responsible for neutralizing and eliminating antigens.
No, t-cell receptors are not considered to be antibodies. While they both play important roles in the immune system, antibodies are a separate class of proteins that function differently from t-cell receptors.
No, t-cell receptors cannot be used in antibody-based therapies. Antibody-based therapies use antibodies to target specific antigens, whereas t-cell receptors are only able to recognize antigens when they are bound to major histocompatibility complexes (MHCs), which are only present on the surface of cells.
T-cell receptors are essential for immune function as they allow T-cells to recognize and respond to foreign invaders and infected or abnormal cells. This recognition and response is crucial for the body's ability to fight off infections and diseases.
