In situ immunophenotypic studies show that tumor infiltrating T lymphocytes from six of 11 fresh cutaneous primary melanomas tested contain T-cell receptor gamma delta expressing cells whereas those from 8 metastatic melanomas did not. In three cases these cells represent an unexpectedly high proportion of the lymphocytic infiltrate, ranging from 15 to 25%. This elevated percentage is maintained when tumor infiltrating lymphocytes are propagated in vitro for 2 or 3 weeks in the presence of recombinant interleukin 2 and autologous tumor cells. Functional studies reveal that gamma delta lines or clones developed from lymphocytes infiltrating primary melanoma display, in addition to their natural killer-like activity, a potent autologous tumor cell cytotoxic activity that does not seem to be restricted by major histocompatibility complex gene products.

UI	MeSH Term	Description	Entries
D008545	Melanoma	A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world.

D013601	T-Lymphocytes	Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.

D016692	Receptors, Antigen, T-Cell, gamma-delta	T-cell receptors composed of CD3-associated gamma and delta polypeptide chains and expressed primarily in CD4-/CD8- T-cells. The receptors appear to be preferentially located in epithelial sites and probably play a role in the recognition of bacterial antigens. The T-cell receptor gamma/delta chains are separate and not related to the gamma and delta chains which are subunits of CD3 (see ANTIGENS, CD3).
