| Résumé : | Mice made neonatally tolerant to alloantigens were found to develop an immunologic disease resembling systemic lupus erythematosus. In BALB/c mice neonatally injected with C57BL/6 X BALB/c F1 hybrid spleen cells, features of autoimmunity were observed first. After 5-24 wk, antinuclear, anti-SS DNA, thymocytotoxic, and rheumatoid factor-like antibodies were detected in association with hypergammaglobulinemia and with the occurrence of circulating immune complexes and cryoglobulins. Some of the antinuclear antibodies were found to be produced by F1 donor B cells persisting in the host. Second, immunopathologic changes were detected in tolerant mice. In the kidneys, an immune complex glomerulonephritis of the membranous type was observed. Immunoglobulin deposits were also found in the choroid plexus and at the dermoepidermal junction. In addition, thrombocytopenia was a common finding, and a positive direct Coomb's test occasionally was detected. Features of autoimmune disease were closely associated with the effective induction of transplantation tolerance, as revealed by the inability of spleen cells to generate in vitro cytolytic responses against C57BL/6 alloantigens. It is suggested that, although transplantation tolerance is associated with a lack of cytolytic reaction of the host against F1 hybrid donor alloantigens, other types of allogeneic interactions could lead in this model to the development of autoimmunity and immunopathology. |
