Cytostasis against self-antigens.

By L De Giorgi, A Matossian-Rogers and H Festenstein

Abstract

Effector cells from mice of the C57Bl/10 congenic series, alloimmunized against K end- or D end-identical I region incompatible lymphocytes, were cytostatic for tumour and macrophage targets bearing syngeneic K-end and D-end antigens. If incompatibility during immunization was restricted to the I-B subregion only, cytostasis was directed against K end syngeneic antigens; further incompatibility in the I region was required to obtain cytostasis against D-end self-antigens. Cytostasis against self-antigens was also obtained after immunization with syngeneic tumour cells; in one instance this was directed against syngeneic K-end antigens only. The implications of these findings in relation to neoplastic change and autoimmune damage are discussed
