The role of RORα in salivary gland lesions in patients with primary Sjogren's syndrome.

ABSTRACT:

Background

The orphan nuclear receptors retinoic acid-related receptor α and γt (RORα and RORγt) are critical in the development of T helper 17 (Th17) cells, and ROR-specific synthetic ligands have proven efficacy in several mouse models of autoimmunity. However, the pathological significance of RORα in primary Sjögren's syndrome (pSS) remains to be elucidated. The present study was designed to clarify the significance of RORα in the pathogenesis of pSS.

Methods

RORα expression in the labial salivary gland (LSG) was determined by immunohistochemical analysis using a quantitative scoring system in 34 patients with pSS. The correlation between RORα expression in LSGs and the focus score (FS) was determined, and Th17 and IL-17 receptor A (1L-17RA) levels in LSGs were determined
