title: Hapten-specific help mediated by an anti-ABA T cell line.
abstract: Long-term cultures of functional T cells were grown from mice injected with azobenzene arsonate (ABA) coupled spleen cells or mice painted with the diazonium salt of p-phenylarsonate. All cell lines produced delayed hypersensitivity to ABA. When tested for helper function in an antibody-forming cell assay only one line, AA3, helped plaque-forming cell formation. It was able to help anti-FLU response of FLU-HGG primed B cells to ABA-KLH-FLU. The help required linkage of the ABA and FLU determinants because cultures stimulated with a mixture of ABA-KLH and TNP-KLH-FLU did not show increased PFC. These experiments demonstrate hapten-specific help in a system which eliminates involvement of passively absorbed antibody in hapten recognition.
