A self determinant recognizing T cell hybridoma.

A T cell hybridoma (53(113)) obtained by fusion of BALB/c spleen cells and the BW 5147 lymphoma T cell line is described. This hybridoma recognizes mouse RBC (MRBC) and rat RBC, but not human, rabbit, guinea pig, or SRBC. The culture supernatant possesses hemagglutinating activity for the same indicator RBC. In addition to this, 53(113) cells are able to form protein A plaques in the presence of guinea pig complement and normal mouse serum (NMS) or purified mouse immunoglobulins (Ig). Because mouse Ig as well as sonicates from MRBC are able to inhibit the rosettes between the hybridoma cells and the MRBC, and because the sonicates inhibit protein A plaque formation, it seems likely that the same product can recognize a similar determinant expressed on MRBC and mouse Ig. The hypothesis that a 53(113) structure recognizes identical or cross-reactive carbohydrate determinants shared by murine Ig and C is considered.
