Expression of reg protein in rat regenerating islets and its co-localization with insulin in the Beta cell secretory granules

Summary Regenerating islets can be induced by the administration of poly(ADP-ribose) synthetase inhibitors to 90% depancreatized rats. In screening a regenerating isletderived cDNA library, we previously isolated a novel gene, reg (regenerating gene), which encodes a 165-amino acid protein with a 21-amino acid signal sequence. In the present study, we have examined the expression and localization of reg protein in the regenerating islets by immunocytochemical techniques using a monoclonal antibody against a recombinant rat reg protein of 144 amino acids without the signal sequence. Light microscopy examination showed strong immunoreactivity for reg protein in the regenerating islets of the rats at two weeks and two months after the 90% pancreatectomy, whereas reg protein was almost undetectable in normal rat islets or in the islets of the rats one year after the pancreatectomy. Almost all the reg protein-positive cells were stained for insulin. By applying the immunogold technique at the ultrastructural level, it was demonstrated that both reg protein and insulin occur in the central granular core of the regenerating Beta cell secretory granules. These results suggest that reg protein is synthesized in and secreted from the regenerating Beta cells and that its expression is closely associated with Beta-cell regeneration.

Anti-eosinophil peroxidase antibodies detected in patients with primary biliary cirrhosis.

OBJECTIVE:: The possible involvement of eosinophils in primary biliary cirrhosis (PBC) has been suggested for many years. Activated eosinophils release basic granule proteins and are thought to be involved in the tissue damage of PBC. Eosinophil peroxidase (EPO) is one of the eosinophilic granule proteins and is toxic to epithelial cells. In this study, we examined whether autoantibodies to EPO are present in sera of patients with PBC and we evaluated the relationship between the presence of anti-EPO antibodies and the clinical features of PBC. METHODS:: Sera obtained from 61 patients with PBC, 31 patients with autoimmune hepatitis (AIH), 87 patients with chronic viral hepatitis (CVH), 27 patients with bronchial asthma, and 20 healthy controls were examined. Enzyme-linked immunosorbent assay (ELISA) and Western blot methods were used for detection of anti-EPO antibodies. RESULTS:: The mean OD value of anti-EPO antibodies, as determined by ELISA, was significantly (p<0.01) higher in patients with PBC (0.197+/-0.121) than in patients with AIH (0.124+/-0.077), CVH (0.090+/-0.038) or bronchial asthma (0.073+/-0.025) and in healthy controls (0.072+/-0.029). The results of ELISA showed that 32 (52.5%) of the 61 patients with PBC, 9 (29.0%) of the 31 patients with AIH, 7 (8.0%) of the 87 patients with CVH, and 1 (3.7%) of the 27 patients with bronchial asthma were positive for anti-EPO antibodies. In addition, PBC patients who were positive for anti-EPO antibodies had a significantly smaller number of peripheral eosinophils than did patients who were negative for anti-EPO antibodies (99.2+/-54.4cells/mul versus 176.9+/-117.5cells/mul, p<0.01). However, there was no correlation between the titers of anti-EPO antibodies and those of AMA or AMA-M2, ANA or serum levels of IgM. CONCLUSIONS:: This is the first report of the detection of anti-EPO antibodies in patients with PBC. Further study is needed to clarify the role of anti-EPO antibodies in the pathogenesis of PBC.
