Popis: Methods were developed to monitor graft rejection in a porcine model of unilateral lung transplantation. The ability of peripheral blood mononuclear cells and lavage-derived mononuclear cells to lyse donor pulmonary tissue was determined by standard chromium release assays at various times after transplantation. Effective anti-graft activity was observed in the local environment of a rejecting graft, but not in the periphery. Since transplant rejection is a reversible process, with the administration of suitable immunosuppressive regimes frequently restoring graft function, it was reasoned that immunological assays based on the lysis of individual cells may not be relevant to the in vivo situation. We therefore describe an assay of the lung barrier function; perturbations of the tight intraepithelial junctions which compose the air-blood barrier can be determined in vitro by the measurement of trans-monolayer resistance values.
