Understanding the molecular basis of Sjögren's disease using omic technologies.

Abstract

Primary Sjögren's disease (SjD) is a chronic autoimmune disease (AD) that primarily affects the exocrine glands, particularly lacrimal and salivary glands, presenting extra glandular manifestations in a significant number of patients. Although it is a prevalent and globally widespread disease, its pathogenesis has not been fully elucidated. Recently, high-throughput omics technologies are providing unprecedented insights into the molecular landscape of various ADs, including SjD. These technical advances are prepared to decipher new aspects of its pathogenesis and to eventually enable the development of more effective treatment strategies. This review explores recent developments in genetics, transcriptomics, epigenomics, proteomics and metagenomics in SjD, highlighting the potential of integrating multiple omics datasets to identify better drug targets and useful biomarkers for precision medicine.
