Key Takeaway

Consider zebrafish models as a framework for advancing mechanistic understanding of TCM neuroprotective therapies.

This review article evaluates the potential of Traditional Chinese medicine (TCM) metabolites for treating various neurological conditions. The scope includes Alzheimer's disease, Parkinson's disease, stroke, cerebral ischemia, epilepsy, insomnia, depression, and spinal cord injury. The authors do not report specific study populations, sample sizes, or adverse events. Instead, they synthesize mechanistic arguments regarding the utility of these metabolites.

The authors describe how TCM metabolites exert neuroprotective effects through multiple mechanisms. These mechanisms include anti-oxidative stress, anti-neuroinflammation, anti-apoptosis, neurotransmitter modulation, neurogenesis promotion, and vascular protection. The review also highlights the utility of zebrafish models for high-throughput screening of active metabolites, real-time in vivo imaging of neurovascular processes, and rapid safety assessment.

However, the authors acknowledge specific limitations in current models. These limitations include the absence of a layered neocortex, differences in drug metabolism, and the predominantly acute nature of current models. No specific numerical data, p-values, or confidence intervals are reported in this review.

The practice relevance of this work is that it provides a practical framework for leveraging zebrafish models to advance the mechanistic understanding and clinical development of neuroprotective TCM therapies. Clinicians should interpret these findings as qualitative arguments rather than quantitative trial results.

Neurological disorders, including Alzheimer’s disease, Parkinson’s disease, and stroke, remain major causes of global disability and mortality, with limited neuroprotective therapies available. Traditional Chinese medicine (TCM) offers multi-target therapeutic potential, but its mechanistic complexity requires systematic investigation using appropriate model systems. Zebrafish (Danio rerio) has emerged as a valuable vertebrate platform for TCM neuroprotection research due to its genetic homology with humans, optical transparency, and high-throughput screening compatibility. This review summarizes the application of zebrafish models in studying TCM for Alzheimer’s disease, Parkinson’s disease, cerebral ischemia, epilepsy, insomnia, depression, and spinal cord injury. Key findings indicate that TCM metabolites exert neuroprotective effects through multiple mechanisms, including anti-oxidative stress, anti-neuroinflammation, anti-apoptosis, neurotransmitter modulation, neurogenesis promotion, and vascular protection. Zebrafish models have proven particularly useful for high-throughput screening of active metabolites, real-time in vivo imaging of neurovascular processes, and rapid safety assessment. However, limitations such as the absence of a layered neocortex, differences in drug metabolism, and the predominantly acute nature of current models must be acknowledged. Addressing these challenges through model standardization, multi-omics integration, and cross-species validation will further enhance the translational relevance of zebrafish-based TCM research. This review provides a practical framework for leveraging zebrafish models to advance the mechanistic understanding and clinical development of neuroprotective TCM therapies.
