In allergic diseases, EVs have emerged as key mediators linking epithelial barriers, immune cells, and the microbiome. EVs derived from epithelial, immune, and microbiota-associated cells may contribute to the initiation, amplification, and persistence of allergic inflammation by modulating barrier integrity, immune cell polarization, and cytokine signaling pathways.

This review provides an up-to-date synthesis of advances in epigenetic drugs for major autoimmune diseases including systemic lupus erythematosus and rheumatoid arthritis, and examines the molecular mechanisms through which these agents modulate immune cell differentiation and function. Accumulating data from preclinical models and clinical studies suggest that epigenetic therapies not only suppress inflammation but also reprogramme aberrant immune states, conferring therapeutic potential for disease amelioration. At present, twelve epigenetic drugs have been approved for cancer, and given the shared epigenetic abnormalities between cancer and autoimmune diseases, extending these therapeutic indications to autoimmune disorders represents a feasible strategy. Moreover, combination regimens incorporating epigenetic drugs have demonstrated enhanced therapeutic efficacy.

Compared with control HDM, Tyr-HDM exhibited significantly reduced allergenic activity in a murine model of allergic asthma, as evidenced by attenuated airway inflammation and diminished T helper 2 (Th2) responses, including reduced IL-4, IL-5 and IL-13 production, accompanied by a notable increase in regulatory T (Treg) cells.

By controlling mRNA stability, microRNA maturation, and ubiquitin-dependent signaling, Regnase-1 fine-tunes inflammatory responses in both innate and adaptive immune cells. Accumulating evidence has demonstrated that dysregulation of Regnase-1 contributes to aberrant immune activation and the development of autoimmune diseases. In this review, we summarize recent advances in understanding the molecular mechanisms underlying Regnase-1 function, including RNase-mediated degradation of proinflammatory transcripts, suppression of microRNA (miRNA) biogenesis, and deubiquitination of key signaling intermediates such as TNF receptor-associated factor (TRAF) family proteins. We further discuss the multilayered regulation of Regnase-1 expression at transcriptional, post-transcriptional, and post-translational levels, highlighting how inflammatory cues dynamically modulate its activity. Importantly, Regnase-1 exerts cell type-specific functions among macrophages, neutrophils, T cells, B cells, and innate lymphoid cells, thereby modulating immune activation, differentiation, and effector responses. Recent studies have linked Regnase-1 to the pathogenesis of autoimmune diseases, including systemic lupus erythematosus (SLE), inflammatory bowel disease (IBD), multiple sclerosis (MS), psoriasis, and type 1 diabetes (T1D), suggesting its potential as a candidate biomarker or therapeutic target in autoimmune disorders. Regnase-1 has been shown to serve as a key negative regulator of inflammatory signaling pathways, including IL-23/IL-17–driven responses implicated in autoimmune pathogenesis. Although available data are largely derived from experimental models and observational clinical studies, current findings collectively highlight Regnase-1 as an upstream regulator of several inflammatory signaling pathways already being targeted in clinical practice.
