MicroRNAs as Regulators, Biomarkers, and Therapeutic Targets in Autism Spectrum Disorder.

The pathogenesis of autism spectrum disorder (ASD) is complex and is mainly influenced by genetic and environmental factors. Some research has indicated that environmental aspects may interplay with genetic aspects to enhance the risk, and microRNAs (miRNAs) are probably factors in explaining this link between heredity and the environment. MiRNAs are single-stranded noncoding RNAs that can regulate gene expression at the posttranscriptional level. Some research has indicated that miRNAs are closely linked to neurological diseases. Many aberrantly expressed miRNAs have been observed in autism, and these dysregulated miRNAs are expected to be potential biomarkers and provide new strategies for the treatment of this disease. This article reviews the research progress of miRNAs in autism, including their biosynthesis and function. It is found that some miRNAs show aberrant expression patterns in brain tissue and peripheral blood of autistic patients, which may serve as biomarkers of the disease. In addition, the article explores the novel role of exosomes as carriers of miRNAs with the ability to cross the blood-brain barrier and unique expression profiles, offering new possibilities for diagnostic and therapeutic interventions in ASD. The potential of miRNAs in exosomes as diagnostic markers for ASD is specifically highlighted, as well as the prospect of using engineered exosome-encapsulated miRNAs for targeted therapies. © 2024.
