The immune checkpoints
Web1 day ago · Immune checkpoints are receptors on the surface of T cells (T cells are a special kind of immune cell). When certain proteins bind to these checkpoint receptors, they inhibit T cell activity. This type of feature on a T cell sounds counter-productive, but checkpoints are important; they prevent an immune system overreaction. ... WebImmune checkpoints are a normal part of the immune system. Their role is to prevent an immune response from being so strong that it destroys healthy cells in the body.
