- T-cell receptor
- listen (… sel reh-SEP-ter)
- A group of proteins found on T cells (a type of immune cell that recognizes and binds to foreign substances). T-cell receptors bind to certain antigens (proteins) found on abnormal cells, cancer cells, cells from other organisms, and cells infected with a virus or another microorganism. This interaction causes the T cells to attack these cells and helps the body fight infection, cancer, or other diseases. Also called TCR.
