Intercellular adhesion molecule 1 on liver allografts during rejection.

Abstract

The expression of intercellular adhesion molecule 1 (ICAM-1), a ligand for the leucocyte adhesion receptor lymphocyte-function-associated antigen 1 (LFA-1), was studied on liver tissue after transplantation. There was greater ICAM-1 expression on bile ducts, endothelium, and perivenular hepatocytes (structures affected by the rejection process) in patients with acute rejection than in donor livers, patients with stable transplants, or patients with non-rejection complications. The expression on bile ducts and hepatocytes was greater in patients in whom there was progression to chronic, irreversible rejection. In patients with resolving rejection ICAM-1 expression was greatly reduced after high-dose corticosteroid treatment. The expression in patients with non-rejection complications and in those with long-term stable grafts was similar to that seen in the donor controls. The induction of ICAM-1 on tissues may be an important step in the development of the inflammatory response of rejection and in determining which cells are the targets of immune damage. The reduction of ICAM-1 expression seen after successful treatment with high-dose corticosteroids suggests that this might be an important mode of action of these drugs.
