Abstract
Reconstitution of lethally irradiated mice with spleen cells from donors that had been treated with lipopolysaccharide (LPS) intravenously and allogeneic spleen cells subcutaneously leads to a suppressed anti-host delayed-type hypersensitivity (DTH). Either donor injection alone proved to be ineffective. The state of suppression appeared to be antigen-specific, but, depending on the experimental conditions, also anti-host DTH to third-party alloantigens could be suppressed. The suppression was mediated by a population of Thy-1- suppressor cells that could also be induced in athymic nude mice. The suppressor cells specifically adhered to anti-kappa-coated plastic plates, but were not adsorbed by passage through a Sephadex G-10 column. Thus, it appears that the combined donor treatment with LPS and allogeneic spleen cells induces a population of B cells that can suppress anti-host immune reactivity.
