  • Title: Immunological unresponsiveness induced by recipient cells transfected with donor MHC genes.
    Author: Madsen JC, Superina RA, Wood KJ, Morris PJ.
    Journal: Nature; 1988 Mar 10; 332(6160):161-4. PubMed ID: 3279318.
    Abstract:
    Immunological unresponsiveness to allografts can be achieved by pretreating recipients with cells (whole blood, erythrocytes, lymphocytes) expressing donor-specific histocompatibility antigens. Attempts to determine the relative contribution of class I or class II major histocompatibility antigens and/or minor histocompatibility (miH) antigens towards the induction of an unresponsive state have yielded conflicting results. We have addressed this issue using DNA-mediated gene transfer to introduce murine class I or class II major histocompatibility complex (MHC) genes from the organ donor into cells of recipient origin. This allowed murine recipients of cardiac allografts to be pretreated with either donor cells sharing only an isolated class I or class II MHC locus product with the donor organ. We show that pretreatment with either donor class I or class II antigens prolongs survival of cardiac allografts, and that the capacity of a particular donor MHC antigen to induce unresponsiveness is the product of its intrinsic immunogenicity and the antigen load delivered during pretreatment. These results explain discrepancies in earlier studies of antigen-induced unresponsiveness and suggest a novel approach to specific immunosuppression in clinical transplantation.
