Abstract

In the present study we used a well-characterised model of murine lupus, the female NZB/W hybrid, to study the possible involvement of neuropeptides in the pathogenesis of systemic lupus erythematosus (SLE). Analysis of neuropeptides with a possible role in inflammation showed that substance P (SP) calcitonin gene-related peptide (CGRP) and neuropeptide Y (NPY) are present in increased quantities in the inflamed kidneys of SLE mice, confirming their involvement in local inflammation, while there is a general reduction in the peptide concentrations in the lymphoid organs of lupus mice, except for NPY. Our results suggest that the altered neuropeptide concentrations observed in the SLE lymphoid organs may be partly responsible for the altered immune response and contribute to the development of autoimmune diseases.
