TOPICS COVERED IN SJOGREN'S SYNDROME: AUTOIMMUNE EPITHELITIS

Characteristics and clinical symptoms of Sjogren's syndrome (SS) - The epithelial component is the mainly affected tissue; injury is associated with dense lymphocytic infiltrates by activated T and B cells - The epithelial cell is a pivotal regulator of the SS autoimmune responses - SS is actually an autoimmune epithelitis - Non-neoplastic salivary gland epithelial cell (SGEC) lines - Epithelial cells possibly participate in the perpetuation of inflammatory responses and to the introduction of autoantigens in the immune system - The critical role of epithelial cells in the regulation of local immune responses in salivary glands
