Exploring the role of exosomal and non-exosomal non-coding RNAs in Kawasaki disease: Implications for diagnosis and therapeutic strategies against coronary artery aneurysms

Abstract

Kawasaki disease (KD) is an acute vasculitis primarily affecting children, with a potential risk of developing coronary artery aneurysms (CAAs) and cardiovascular complications. The emergence of non-coding RNAs (ncRNAs), including microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), has provided insights into Kawasaki disease pathogenesis and opened new avenues for diagnosis and therapeutic intervention. Furthermore, polymorphism analysis of ncRNA genes offers significant insights into genetic predisposition to Kawasaki disease, facilitating tailored treatment approaches and risk assessment to improve patient outcomes. Exosomal ncRNAs, which are ncRNAs encapsulated within extracellular vesicles, have garnered significant attention as potential biomarkers for Kawasaki disease and CAA due to their stability and accessibility in biological fluids. This review comprehensively discusses the biogenesis, components, and potential of exosomal and non-exosomal ncRNAs in Kawasaki disease diagnosis and prognosis prediction. It also highlights the roles of non-exosomal ncRNAs, such as miRNAs, lncRNAs, and circRNAs, in Kawasaki disease pathogenesis and their implications as therapeutic targets. Additionally, the review explores the current diagnostic and therapeutic approaches for Kawasaki disease and emphasizes the need for further research to validate these ncRNA-based biomarkers in diverse populations and clinical settings.
