Special Issue Information

Dear Colleagues,

Autoimmune rheumatic diseases (AIRDs) are chronic, systemic diseases characterized by unknown etiology and pathogenesis. Recent studies have revealed the multifactorial basis of AIRD with the leading role of genetic and epigenetic factors as well as environmental factors in disease predisposition, onset and progression. Epigenetic factors, including DNA methylation, histone modifications and deregulated miRNA expression in circulation, in addition to local expression, play an important role in the pathogenesis of AIRD by regulating key biological pathways.

Significant advances have been made in the search for serological and proteomic biomarkers, which could be used as predictors of disease onset and severity. The implementation of newer imaging technics offers an earlier diagnosis rate and safer follow-up of these subtypes of patients.

The recent advances in our understanding of the pathogenesis of AIRD enable the development of effective therapeutic agents, including biological and target therapies minimizing the side-effects of non-selective immunosuppressive agents. Recent studies have shown the effects of new therapeutic strategies, including the use of CAR-T cell therapies, and Bi-specific T-cell engagers, in rheumatology clinical practice, which could allow us to revolutionize the treatment approach in this type of autoimmune diseases.

Systemic sclerosis (SSc) is a chronic autoimmune connective tissue disorder characterized by three main pathological features: microangiopathy, immunological alterations, and excessive synthesis of extracellular matrix (ECM) proteins, leading to fibrosis of the skin and internal organs. Although the etiology of SSc is still unknown, recent studies have revealed the potential role of genetic and epigenetic factors in disease pathogenesis. They are involved in the regulation of cell metabolism, cell hyperactivity, and the accumulation of extracellular matrix proteins. Short endogenous noncoding RNA molecules (microRNAs; miRNAs) negatively regulate gene expression at the posttranscriptional level and play a significant role in disease pathogenesis. Altered miRNA expression in circulation and disease-specific tissues could serve as biomarkers and potential therapeutic targets in SSc. Full article
