PG - 200-6 AB - OBJECTIVE: To determine the role of the novel proinflammatory cytokine high mobility group box chromosomal protein 1 (HMGB-1) in the pathogenesis of lupus nephritis. METHODS: Serum levels of anti-dsDNA antibodies were determined by enzyme linked immunosorbent assay (ELISA). Renal morphologic features were examined by light microscopy, electron microscopy, and immunohistologic analyses. The mRNA expression of HMGB-1 and monocyte chemoattractant protein-1 (MCP-1) was detected by RT-PCR. RESULT: MRL/lpr mice demonstrated characteristic alterations of serum immune parameters, with progressively increased anti-dsDNA antibodies with age, compared with age-matched C57BL/6J mice. MRL/lpr mice showed progressive development of renal damage, starting at 12 weeks of age and reached the peak at 20 weeks. The observed lesions included the presence of enlarged hypercellular glomeruli, with increased numbers of both resident cells and infiltrating leukocytes. Higher expression of HMGB-1 mRNA was found in MRL/lpr mice than what in C57BL/6J mice. Expression of HMGB-1 was positively correlated with that of MCP-1 mRNA. CONCLUSION: The results demonstrate that the higher expression of HMGB-1 may contribute to the pathogenesis of lupus nephritis.
