Spinal Cord Injury Management Based on Microglia-Targeting Therapies

J. Clin. Med., 2024 · DOI: 10.3390/jcm13102773 · Published: May 8, 2024

Simple Explanation

Spinal cord injury (SCI) is a complex medical issue with unsatisfactory recovery. Modern techniques don't always lead to improvement, creating a need for new treatments. This review explores therapies that target microglia, key immune cells in spinal cord disorders. These therapies aim to modulate microglia to improve outcomes. Emerging treatments include cytokines modulators, stem cells, microRNA, and nanoparticle-based approaches. These could positively impact spinal cord injury management.

Key Findings

1
Microglia play a crucial role in the posttraumatic phenomena, particularly in neuroinflammation following spinal cord injury.
2
Activated microglia exhibit various phenotypes with neurotoxic or neuroprotective effects depending on external stimuli.
3
Microglia significantly influence non-neuronal cells in the spinal cord, particularly astrocytes, which are closely associated.

Research Summary

Spinal cord injuries lead to debilitating neurological impairments. Microglia play a critical role in both inflammation and repair processes following SCI. Numerous therapeutic strategies targeting microglia have recently been proposed. This includes therapies based on CSF1R inhibitors, cytokines modulation, stem cells, microRNAs, and nanoparticles. Achieving a precise balance of pro- and anti-inflammatory molecule secretion during different stages of SCI is crucial for optimal outcomes.

Practical Implications

Targeted Therapies

Microglia-targeting treatments such as CSF1R inhibitors, cytokine therapy, stem cell transplantation, and microRNA modulation show promise for improving SCI outcomes.

Drug Delivery Systems

Nanoparticles, exosomes, and other drug delivery systems can enhance therapeutic transfer to injury sites, particularly in the spinal cord's grey matter.

Combination Therapies

Combining biological tissue engineering or cell transplantation techniques with drug therapy provides a comprehensive approach to treating SCI.

Study Limitations

1
Disparities between preclinical and clinical trial results
2
Lack of funding for scientific research
3
Optimal timing and combination of experimental therapeutic approaches remain unanswered
