EXPRESS: A Road to Recovery: Transient Receptor Potential (TRP) Channels as Therapeutic Avenues for Spinal Cord...

Area of Science:

• Neuroscience
• Molecular Biology
• Pharmacology

Background:

• Spinal cord injury (SCI) causes secondary damage like inflammation and oxidative stress, worsening neurological deficits.
• Transient receptor potential (TRP) channels are key molecular players in SCI pathology, influencing pain, inflammation, and cell death.
• Specific TRP channel subtypes (e.g., TRPV1, TRPA1, TRPM2, TRPM7, TRPC6, TRPML1) have distinct roles in SCI.

Purpose of the Study:

• To review the role of TRP channels in the secondary injury cascade following SCI.
• To highlight TRP channels as potential therapeutic targets for SCI.
• To discuss challenges and future strategies for TRP channel modulation in SCI treatment.

Main Methods:

• Literature review of studies investigating TRP channel function in SCI.
• Analysis of molecular mechanisms by which TRP channels contribute to SCI pathology.
• Evaluation of current therapeutic strategies and their limitations.

Main Results:

• TRP channels (TRPV1, TRPA1, TRPM2, TRPM7, TRPC6, TRPML1) are implicated in SCI-induced pain, inflammation, oxidative stress, and barrier dysfunction.
• TRP channels modulate astrocyte reactivity and autophagy, impacting neuroprotection.
• Existing TRP modulators lack selectivity and can cause systemic toxicity, hindering clinical application.

Conclusions:

• TRP channels are critical regulators of SCI pathophysiology and represent promising therapeutic targets.
• Overcoming challenges in TRP channel modulator selectivity and targeted delivery is essential for clinical translation.
• Multimodal therapeutic strategies integrating TRP modulation are needed for effective SCI treatment.
