Colchicine (CC) enhances the antibody response in mice to protein antigens, like diphtheria toxoid and human gamma globulin, as well as to the 2,4,6-trinitrophenyl hapten. Maximal enhancement was observed when CC was administered to animals on the same day as the injection of antigen. The optimal dose of CC was in the range of 1.0-1.5 mg/kg body weight. The(More)
The simultaneous administration of colchicine (CC) with a T-independent antigen, e.g. 2,4,6-trinitrophenyl-keyhold limpet hemocyanin-Sepharose, to intact animals effectively enhanced their hapten-specific plaque-forming cell (PFC) response. However, in congenitally athymic nude mice in which T-cell regulation was absent, CC was ineffective in producing(More)
