Neurotrophins and acupuncture

Area of Science:

• Neuroscience
• Integrative Medicine
• Traditional Chinese Medicine

Background:

• Acupuncture, a component of Traditional Chinese Medicine (TCM), is recognized for its efficacy in managing pain, inflammation, and mood disorders.
• Its therapeutic mechanisms are increasingly linked to the stimulation of sensory afferent fibers, triggering physiological responses akin to exercise or massage.
• While endogenous opioids were initially considered primary mediators, recent research highlights neurotransmitters, cytokines, and growth factors.

Purpose of the Study:

• To review recent findings and ongoing research on acupuncture's effects on endogenous biological mediators.
• To specifically focus on neurotrophins, such as nerve growth factor (NGF) and brain-derived neurotrophic factor (BDNF).
• To highlight the role of NGF as a mediator of acupuncture's central nervous system (CNS) effects and its modulation of sensory and autonomic activity.

Main Methods:

• Literature review of recent findings and ongoing studies.
• Focus on neurotrophins (NTs) as mediators of acupuncture's effects.
• Emphasis on laboratory investigations into nerve growth factor (NGF) in the CNS.

Main Results:

• Acupuncture's effects extend beyond endogenous opioids to include neurotransmitters, cytokines, and growth factors.
• Neurotrophins (NTs) are identified as significant mediators of neural activity, plasticity, and repair.
• Nerve growth factor (NGF) plays a crucial role in mediating acupuncture's central nervous system effects.

Conclusions:

• Acupuncture modulates endogenous biological mediators, particularly neurotrophins.
• Neurotrophins are vital for neural plasticity and repair, and acupuncture influences these processes.
• Further research, including laboratory studies on NGF, is essential for understanding acupuncture's full therapeutic potential in the CNS.
