Systemic sclerosis (SSc) is a multifaceted connective tissue disease whose aetiology remains largely unknown. Autoimmunity thought to play pivotal role in the development of disease, but direct pathogenic SSc-specific autoantibodies be established. The recent discovery functional antibodies targeting G-protein-coupled receptors (GPCRs), presence has been demonstrated different autoimmune conditions, shed some light on SSc pathogenesis. These bind GPCRs expressed immune and non-immune cells as their endogenous ligands, exerting either stimulatory or inhibitory effect corresponding intracellular pathways. Growing evidence suggests that, SSc, anti-GPCRs correlates with specific clinical manifestations. Autoantibodies endothelin receptor type A (ETAR) angiotensin 1 (AT1R) are associated severe vasculopathic SSc-related manifestations, while anti-C-X-C motif chemokine (CXCR) seem predictive interstitial lung involvement; anti-muscarinic-3 acetylcholine (M3R) have found patients gastrointestinal involvement anti-protease-activated (PAR1) detected experiencing scleroderma renal crisis.

This study aimed to analyze potential biomarkers for systemic sclerosis (SSc) by constructing lncRNA-miRNA-mRNA networks in circulating exosomes (cirexos). Differentially expressed mRNAs (DEmRNAs) and lncRNAs (DElncRNAs) SSc cirexos were screened using high-throughput sequencing detected with real-time quantitative PCR (RT-qPCR). genes (DEGs) analyzed the DisGeNET, GeneCards, GSEA4.2.3, Gene Ontology (GO), Kyoto Encyclopedia of Genes Genomes (KEGG) databases. Receiver operating characteristic (ROC) curves, correlation analyses, a double-luciferase reporter gene detection assay used competing endogenous RNA (ceRNA) clinical data. In this study, 286 DEmRNAs 192 DElncRNAs screened, which 18 DEGs same as SSc-related genes. The main pathways included extracellular matrix (ECM) receptor interaction, local adhesion, platelet activation, IgA production intestinal immune network.
