title: Induction of a stable hapten-specific immunosuppression by a hapten conjugated to poly(N-vinylpyrrolidone) (PVP).
abstract: The ability of a hapten coupled to a clinically permissive synthetic polymer (NIP-PVP) to induce suppression was investigated. NIP coupled to the low molecular weight non-immunogenic form of poly(N-vinylpyrrolidone) (PVP) was found to be capable of inducing a hapten-specific longlasting suppression of both primary and secondary responses. The previous use of PVP as a plasma expander in humans makes this polymer a potentially suitable tool for the induction of specific immunosuppression to a variety of clinically important drug and tissue specific epitopes. The possible use of low molecular weight PVP for that purpose will be investigated further, specifically with larger antigenic components.
