Hapten specific unresponsiveness in mice. I. Characteristics of unresponsiveness induced by 2,4,6-trinitrobenzene sulphonic acid.
Injection of mice with the chemically reactive hapten 2,4,6-trinitrobenzene sulphonic acid (TNBSA) induces a specific unresponsiveness as judged by reduction or abolition of the anti-TNP response to TNP-KLH. The normal response to a nonrelated hapten, oxazolone, bound to the same carrier (OX-KLH) is unaffected. Reduction of the anti-TNP response was also observed after TNBSA treatment, in nude mice (nu/nu) and their littermates (nu/+) challenged with TNP-POL, an antigen to which the response is thymus independent. Injection of the chemically non-reactive hapten TNP-glycyl-glycine did not induce unresponsiveness. A similar failure was observed with TNP autologous red cells or serum proteins from mice previously injected with TNBSA. The specific unresponsiveness of spleen cells of TNBSA injected mice was maintained after their transfer into lethally irradiated syngeneic host mice. Finally tolerant cells do not inhibit specifically an adoptive anti-TNP secondary response.
