Moxibustion Activates Macrophage Autophagy and Protects Experimental Mice against Bacterial Infection

Abstract EN

Moxibustion is one of main therapies in traditional Chinese medicine and uses heat stimulation on the body surface from the burning of moxa to release pain or treat diseases.

Emerging studies have shown that moxibustion can generate therapeutic effects by activating a series of signaling pathways and neuroendocrine-immune activities.

Here we show moxibustion promoted profound macrophage autophagy in experimental Kunming mice, with reduced Akt phosphorylation and activated eIF2α phosphorylation.

Consequently, moxibustion promoted bacterial clearance by macrophages and protected mice from mortality due to bacterial infection.

These results indicate that moxibustion generates a protective response by activating autophagy against bacterial infections.
