Low density of Thy 1 antigen on mouse effector cells mediating natural cytotoxicity against tumor cells. 1978

R B Herberman, and M E Nunn, and H T Holden

Mouse effector cells mediating natural cell-mediated cytotoxicity against tumor cells were found to contain a low density of Thy 1 antigen. Treatment of nude spleen cells, or spleen cells from mice in which natural reactivity was boosted, with anti-Thy 1.2 plus complement resulted in a substantial decrease in cytotoxicity. The spontaneous cytotoxic reactivity of young, thymus-bearing mice was resistant to such treatment, but repeated exposure to anti-Thy 1.2 plus complement did cause a decrease in lytic activity. By use of congenic anti-Thy 1.2 and effector cells from mice congenic for Thy 1, the effects of the treatment were shown to be specific for Thy 1.2 antigen.

UI	MeSH Term	Description	Entries
D007141	Immunoglobulin Fc Fragments	Crystallizable fragments composed of the carboxy-terminal halves of both IMMUNOGLOBULIN HEAVY CHAINS linked to each other by disulfide bonds. Fc fragments contain the carboxy-terminal parts of the heavy chain constant regions that are responsible for the effector functions of an immunoglobulin (COMPLEMENT fixation, binding to the cell membrane via FC RECEPTORS, and placental transport). This fragment can be obtained by digestion of immunoglobulins with the proteolytic enzyme PAPAIN.

D007519	Isoantigens	Antigens that exist in alternative (allelic) forms in a single species. When an isoantigen is encountered by species members who lack it, an immune response is induced. Typical isoantigens are the BLOOD GROUP ANTIGENS.	Alloantigens,Alloantigen,Isoantigen
D007694	Killer Cells, Natural	Bone marrow-derived lymphocytes that possess cytotoxic properties, classically directed against transformed and virus-infected cells. Unlike T CELLS; and B CELLS; NK CELLS are not antigen specific. The cytotoxicity of natural killer cells is determined by the collective signaling of an array of inhibitory and stimulatory CELL SURFACE RECEPTORS. A subset of T-LYMPHOCYTES referred to as NATURAL KILLER T CELLS shares some of the properties of this cell type.

D008810	Mice, Inbred C57BL	One of the first INBRED MOUSE STRAINS to be sequenced. This strain is commonly used as genetic background for transgenic mouse models. Refractory to many tumors, this strain is also preferred model for studying role of genetic variations in development of diseases.

D003602	Cytotoxicity, Immunologic	The phenomenon of target cell destruction by immunologically active effector cells. It may be brought about directly by sensitized T-lymphocytes or by lymphoid or myeloid "killer" cells, or it may be mediated by cytotoxic antibody, cytotoxic factor released by lymphoid cells, or complement.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
