Research Abstract

Sjogren’s syndrome (SS) is a chronic autoimmune disease, characterized by inflammation of salivary and lacrimal glands, leading to dry mouth and dry eye. The regenerating gene (Reg) was originally isolated as a gene specifically overexpressed in regenerating pancreatic islets. In this study, we examined the expression of REG genes in the salivary glands (SG) and anti-REG autoantibodies in SS. These data strongly suggest that autoimmunity to REG may play a role in the degeneration of SG ductal epithelial cells in SS.
