Discussion

Experimental analysis reveals that electroacupuncture improves pain thresholds in fibromyalgia, suggesting CB1 signaling is crucial for analgesia.

Electroacupuncture significantly improved pain thresholds in a mouse model of fibromyalgia, indicating its therapeutic potential.
Mice showed altered cannabinoid receptor 1 expression and nociceptive signaling, linked to hyperalgesia in fibromyalgia.
Chemogenetic modulation in the paraventricular nucleus affected pain sensitivity via cannabinoid receptor pathways, supporting targeted therapies.
The study confirms that targeting CB1 signaling can reverse hyperalgesic conditions, highlighting a pathway for fibromyalgia treatment.

Hsiao et al. (2025) studied this question.
