Abstract: OBJECTIVE: . METHODS: . Immunohistochemistry, western blot, and immunofluorescence were used to evaluate the mechanism of acu-exo on ALI. P2X7 knockout mice and P2X7 siRNA were used to verify the mechanism. RESULTS: Compared with normal mice, serum exosomes were significantly increased in normal mice after acupuncture. The results showed that P2X7 was increased in the lung of septic mice as compared with the WT group. It was also found that the increase in NLRP3 and NF-κB was accompanied by the activation of P2X7. Increased P2X7 led to activation of the P2X7 receptor causing mitochondrial dysfunctions in lung tissue of septic mice. Knockout of P2X7 or silenced P2X7 markedly decreased NLRP3 and NF-κB and led to mitochondrial function recovery in lung tissue of sepsis. At the same time, acu-exo significantly restored the above changes in the lung tissue of septic mice. CONCLUSIONS: Inhibition of P2X7 led to mitochondrial function recovery of lung tissue by inhibiting NLRP3 and NF-κB. At the same time, acu-exo could improve ALI by decreasing NLRP3 and NF-κB activation.
