IL-17 drives salivary gland dysfunction via inhibiting TRPC1-mediated calcium movement in Sjogren's syndrome.

ABSTRACT:

Objectives

This study aims to determine a role of interleukin-17A (IL-17) in salivary gland (SG) dysfunction and therapeutic effects of targeting IL-17 in SG for treating autoimmune sialadenitis in primary Sjögren's syndrome (pSS).

Methods

Salivary IL-17 levels and IL-17-secreting cells in labial glands of pSS patients were examined. Kinetic changes of IL-17-producing cells in SG from mice with experimental Sjögren's syndrome (ESS) were analysed. To determine a role of IL-17 in salivary secretion, IL-17-deficient mice and constructed chimeric mice with IL-17 receptor C (IL-17RC) deficiency in non-hematopoietic and hematopoietic cells were examined for saliva flow rates during ESS development. Both human and murine primary SG epithelial cells were treated with IL-17 for measu
