Research Progress of Traditional Chinese Medicine in Treating Central Nervous System Diseases by Modulating Ferroptosis

A newly proposed form of programmed cell death, ferroptosis, is distinct in cellular morphology, biochemical characteristics, and genetic characteristics from apoptosis, autophagy, and necrosis. Its mechanisms primarily encompass iron overload, lipid peroxidation, and amino acid metabolisms. Extensive research confirms that ferroptosis is linked to the onset and progression of various diseases that pose a threat to the central nervous system (CNS), offering new directions and targets for the mechanistic study and pharmacotherapy of CNS diseases. Traditional Chinese Medicine (TCM), encompassing herbal medicines (extracts, compound formulations, injections, etc.), acupuncture, and moxibustion, boasts advantages over other treatments, such as multi-pathway and multi-target approaches and high safety. TCM has also demonstrated good efficacy in treating CNS diseases. Numerous studies indicate that TCM can modulate ferroptosis to treat CNS diseases, showing promising research prospects. This paper briefly outlines the pathways and mechanisms of ferroptosis and systematically summarizes the current status and progress of TCM in regulating various CNS diseases through the ferroptosis pathway, providing new insights and directions for future TCM treatments of CNS diseases.
