T. and MRC-OX17, which both recognize the la-antigen immunohistochemically and immune electron microscopically. la-positive cells with a dendritic morphology were found in the connective tissue of the cxocrine and endocrine pancreas. Immune e1ectron microscopically, the Ia-antibodies were 10- calized on the cell surface and in sm all vesicles. A small portion of the la-positive cells showed additional acid phosphatase positivity, i. e. were la-positive macrophages. The other la-positive cells were probably LDC, which may be important in the elimination of foreign antigens, e. g. bacteria and vIruses.

A1 - Ulrichs, Karin A1 - Müller-Ruchholtz, W. T1 - Carbohydrate-specific human heterophile antibodies in normal human sera that react with xenogeneic cells N2 - Human heterophile antibodies (HHA) that are present in normal human sera (NHS)play an important role in hyperacute xenograft rejection. The aim of this study was to analyze the occurrence, mode of action and molecular specificity of HHA in NHS that are directed against xenogeneic Iymphocytes (isolated from mouse, rat, guinea pig, rabbit, cattle and pig) and isolated rat pancreatic islets. All sera contained variable amounts of HHA that killed the target cells via the classical complement pathway. The cytotoxic activity of these HHA was specifically inhibited by certain carbohydrates (a-D-melibiose, ß-Iactose, ß-gentiobiose, ß-cellobiose, D-mannose, N-acetyl-ß-D-mannosamine and a-D-rhamnose) and by rat IgM. By means of affinity chromatography with immobilized inhibitors we obtained an antibody preparation of mainly IgG type from NHS (up to 3.5 mg/IO ml serum) that reacted strongly with rat lymphocytes and isolated rat pancreatic islets. Though thus far residual xenospecific antibody activity has remained in the sera even after multiple affinity chromatography, these data suggest that specific elimination of HHA is feasible and that it may be thus possible to overcome a major obstacle to xenotransplantation.
