Powerful immunosuppression by a new 40-kd serum protein (KX-5) induced by liver transplantation.
The presence of novel immunosuppressive proteins in the serum of liver grafted rats is associated with the induction of tolerance. This may provide part of the explanation for the induction or maintenance of tolerance in this liver graft mode, although their relationship to the antigen-specific aspects of liver graft survival (clonal deletion of T cells, release of soluble class I antigen, production of anti-class II antibodies) remains to be investigated. The KX-5 protein was nonspecifically immunosuppressive in vivo, suggesting the possibility of harnessing the tolerogenic properties of liver grafts in a soluble form for clinical application.
