Split immunosuppression of contact cell-mediated and of IgE hypersensitivity responses to dinitrofluorobenzene in mice.
Contact sensitivity (CS), anti-DNP (dinitrophenyl) IgG and IgE type antibodies were induced by skin applications of the contact sensitizer dinitrofluorobenzene. CS response was suppressed by treatment with the monovalent hapten dinitrobenzene sulfonate (DNBS) but was not affected by treatment with the DNP-conjugates (DNP22-Ficoll, DNP17-polyethylene glycol and DNP2-polyvinylpyrrolidone). On the other hand, IgE type response was depressed by treatment with the various DNP conjugates but was not affected by DNBS. The IgG type response was not appreciably affected by any of the treatments.
