title: Down-regulation of murine contact sensitivity by hapten-amino acid derivatives.
abstract: The low responsiveness of contact sensitivity (CS) in sensitized and challenged mice was induced by using hapten-amino acid derivatives. Subcutaneous injection of trinitrophenyl (TNP)-lysine or oxazolone-glycine inhibited ear swelling responses in mice that received rechallenge. The inhibitory effect was long-lasting and antigen-specific. TNP-lysine blocked the transfer of CS in vivo and the binding of immune lymph node cells to antigen in vitro. Thus, the suppression was mediated by inhibition of effector cells, but not associated with the generation of efferent limb-acting suppressor cells. The tool reported herein seems to be quite useful for controlling ongoing murine CS to simple chemicals.
