title: Lipopolysaccharide-induced suppression of DTH-reactivity to histocompatibility antigens. I. Kinetic aspects and specificity.
abstract: The effects of bacterial lipopolysaccharide (LPS) on the development of DTH-reactivity to alloantigens in mice were investigated. DTH to a particular set of alloantigens could be suppressed by treatment of responder mice with a single intravenous (i.v.) injection of 100 micrograms LPS and a simultaneous subcutaneous (s.c.) injection of the appropriate allogeneic spleen cells. The suppression lasted at least 60 days and affected the afferent limb of the DTH response as well as the efferent limb. The suppression could be adoptively transferred to naive syngeneic recipient mice by spleen cells, but not by immune serum, and proved to be antigen-specific. In spite of this specificity, the DTH-response against unrelated "third-party" alloantigens could be suppressed as well, provided the latter were presented during the induction-phase of DTH together with the alloantigens that had been used for the induction of suppression.
