  Purpose
The main objective of the study is to characterize the gene expression in immune and epithelial cells in salivary gland biopsy samples and blood of pSS (primary Sjögren's syndrome) and non-pSS participants including healthy volunteers.

Condition Intervention
Healthy Sjögren's Syndrome Procedure: Biopsy

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Biomarker Study to Determine the Gene Expression Signatures of Salivary Gland and Blood in Subjects With Incident Primary Sjögren's Syndrome, Subjects With Sicca, and Healthy Volunteers

Primary Outcome Measures:
  • Gene expression levels in immune cells (innate and adaptive) in salivary gland biopsy samples from participants with and without pSS including healthy volunteers [ Time Frame: Up to 12 months ]
  • Gene expression levels in immune cells (innate and adaptive) in blood samples from participants with and without pSS including healthy volunteers [ Time Frame: Up to 12 months ]
  • Gene expression levels in epithelial cells in salivary gland biopsy samples from participants with and without pSS including healthy volunteers [ Time Frame: Up to 12 months ]
  • Gene expression levels in epithelial cells in blood samples from participants with and without pSS including healthy volunteers [ Time Frame: Up to 12 months ]

Biospecimen Retention:   Samples With DNA
A lip biopsy is taken to determine Sjogrens diagnosis.
