Abstract

Antigen-specific tolerance was induced in mice by the lethal irradiation followed by reconstitution with syngeneic, anti-T-cell-treated bone marrow and injection of the protein antigen lysozyme. Animals tolerized with lysozyme responded normally to a second antigen, sheep red blood cells, and animals treated with the same tolerizing regimen using a different protein antigen, bovine serum albumin, responded normally to lysozyme. Challenge of the tolerant mice with lysozyme covalently coupled to LPS induced an antilysozyme response indicating that if tolerance was expressed on the B-cell level that antigen-specific B-cells were still present. These results eliminate clonal abortion and clonal selection as the mechanism of tolerance generation. The tolerance by this procedure is either expressed on the T-cell level or is produced by a state of B-cell clonal anergy which can be overcome by the use of antigen coupled to lipopolysaccharide.
