| epitopes, b-lymphocyte | Antigenic determinants recognised and bound by the B-cell receptor. Epitopes recognised by the B-cell receptor are located on the surface of the antigen. (12 Dec 1998) |
| epitopes, t-lymphocyte | Antigenic determinants recognised and bound by the T-cell receptor. Epitopes recognised by the T-cell receptor are often located in the inner, unexposed side of the antigen, and become accessible to the T-cell receptors after proteolytic processing of the antigen.

| tumour-infiltrating lymphocyte | <haematology, oncology> Special cancer-fighting cells of the immune system found in tumours. In a type of experimental therapy, scientists harvest these cells from the tumour, grow them in a laboratory and then return them to the patient with the hope of the cells destroying the tumour. These cells can be collected from the site of a tumour and exposed to IL-2 in vitro. When these cells are injected back into the tumour bearing host, they will specifically kill the tumour from which they originated. (05 Mar 2000) |
