Decoding chemotherapy-induced peripheral neuropathy: ion channels, disease models, and future directions

Area of Science:

• Oncology
• Neuroscience
• Pharmacology

Background:

• Chemotherapy-induced peripheral neuropathy (CIPN) significantly reduces cancer patient quality of life (QoL).
• Underlying mechanisms of CIPN remain poorly understood, and effective treatments are scarce.
• Paclitaxel and oxaliplatin are common chemotherapeutics known to cause CIPN.

Purpose of the Study:

• To evaluate the translational validity of current experimental models for CIPN.
• To highlight recent molecular and cellular discoveries, particularly the role of sensory ion channels.
• To propose enhanced preclinical models for better CIPN research.

Main Methods:

• Review of existing literature on CIPN mechanisms and experimental models.
• Analysis of molecular and cellular findings, focusing on sensory ion channels.
• Assessment of current model limitations and proposal of translational preclinical strategies.

Main Results:

• Existing experimental models often fail to fully recapitulate CIPN complexity and patient variability.
• Sensory ion channels are increasingly recognized as critical players in CIPN pathogenesis.
• There is a need for more predictive preclinical models to guide therapeutic development.

Conclusions:

• Improved experimental models are crucial for advancing our understanding of CIPN.
• Developing more translational models will facilitate the creation of effective CIPN interventions.
• Prioritizing supportive care is essential for managing chemotherapy side effects and improving patient well-being.
