antigen receptors and accessory molecules of t lymphocytes
... The idea that cells may have specific surface receptors that can be triggered by external ligands came from one of the founders of modern immunology. Paul Ehrlich, in his “side chain theory,” published in 1897, conceived of antibodies on the surface of immune cells that recognize antigens and instru ...
