The role of the purinergic system in the acupuncture-induced analgesia

Abstract

ABSTRACT BACKGROUND AND OBJECTIVES: Musculoskeletal disorders and acute and chronic pain are the main causes of disability. Acupuncture is a safe and well-tolerated treatment, and the understanding of the physiological basis of its effectiveness in the management of acute and chronic painful conditions is growing. The objective of this study was to describe the main components of the purinergic system involved in the acupuncture-mediated analgesia. CONTENTS: Review the literature relevant to the terms “acupuncture”, “purinergic system”, “purines”, “pain” and “analgesia” found on the Pubmed platform. CONCLUSION: Several previous studies have shown relevant roles of purines and their derivatives on acupuncture-mediated analgesia, displaying promising results in the knowledge of the potential biological benefits of acupuncture. New experimental and clinical studies are warranted to further investigate the purinergic mechanisms involved in the acupuncture-mediated analgesia, addressing potential therapeutic benefits of acupuncture in different clinical settings.
