Acupuncture-driven exosomes: an emerging therapy

Acupuncture, as a significant component of Traditional Chinese Medicine (TCM), has attracted increased attention for its mechanism of controlling the physiological functions of the human body and promoting the recovery of diseases by stimulating specific acupoints. Despite its long history and wide clinical application, the mechanism of action of acupuncture is still not fully understood. More research needs to be done on how acupuncture affects molecular communication and cellular function. Exosomes are nanoscale vesicles that rely on cellular multivesicular bodies (MVBs) fused with cell membranes to be released into the extracellular matrix. They are crucial for information transfer between cells and are currently a hot research topic in the world's cutting-edge life sciences. Previous research has demonstrated that the therapeutic effect of acupuncture may be related to stimulating certain cells to secrete exosomes, that exosomes released may contain "acupuncture information", and that manipulating the back-injection of exosomes to produces "acupuncture-like" effects. These findings suggest that exosomes could serve as a bridge between conventional acupuncture therapy and modern precision medicine. They also offer fresh prospects and difficulties for acupuncture translational medicine research. To better define the relationship between exosomes and acupuncture, we reviewed and systematized the literature on past studies related to exosomes and acupuncture. This paper provides a significant theoretical and experimental foundation for applying exosomes in precision medicine by summarizing and analyzing the relationship between acupuncture stimulation and exosome function. This is expected to promote the combination of traditional acupuncture therapy and modern biotechnology and bring innovation and progress to future medical practice.
