Disclosed are methods for inhibit rejection of a graft in a patient. The methods involve treating the graft with a molecule which binds to a co-stimulatory protein of antigen-presenting cells. Useful molecules include chimeras having enzymatically inactive polypeptides bonded to polypeptides which bind to co-stimulatory proteins of antigen-presenting cells. Also disclosed, are chimeric molecules composed of lytic IgG Fc bonded to CD2, CD28, CD40L, or CTLA-4. In addition, disclosed are methods for inhibiting rejection of a graft in a patient; the methods involve treating the brain-dead, beating heart donor of the graft, prior to removal of the graft from the donor, to render the graft less susceptible to rejection by the patient.
