miRNA-Mediated Regulation of Ferroptosis in Neurological Disorders: Mechanisms and Therapeutic Implications.

Ferroptosis is a form of regulated cell death driven by iron-dependent phospholipid peroxidation and has emerged as a key mechanism of neuronal injury across a broad spectrum of neurological disorders. MicroRNAs (miRNAs), which function primarily as post-transcriptional regulators of gene expression, are increasingly recognized as important modulators of the regulatory networks governing ferroptosis and as potential therapeutic targets in these conditions. In this review, we synthesize current advances in miRNA-mediated regulation of ferroptosis in neurological disorders. We first outline the core molecular pathways governing ferroptosis, with particular emphasis on antioxidant defense, lipid peroxidation, and iron metabolism. We then integrate evidence from ischemic stroke, intracerebral hemorrhage, epilepsy, toxic encephalopathy, spinal cord injury, Parkinson's disease, and Alzheimer's disease, to illustrate how disease-specific miRNA regulatory axes shape ferroptotic vulnerability and its pathological consequences in distinct neurological settings. Importantly, we highlight exosome-based strategies targeting ferroptosis-related miRNA networks as a promising therapeutic approach for neurological disorders, with demonstrated neuroprotective and functional benefits in preclinical studies. Collectively, current evidence supports miRNA-mediated regulation of ferroptosis as an important mechanistic framework and a promising therapeutic target in neurological disorders.
