Bottom Line: This study observed the effect of moxibustion on the TLR2/NF-κB signaling pathway at the Tianshu (ST25) and Qihai (CV6) acupuncture points in the UC rat.Similarly, the expression of NF-κB was significantly increased and IFN-β and IL-10 were significantly decreased in the colonic mucosa of UC rats, but herb-partitioned moxibustion reduced the expression of IFN-β and upregulating the expression of IFN-β and IL-10 significantly.It indicates that herb-partitioned moxibustion can inhibit the expression of multiple signaling molecules of the TLR2 pathway effectively, and it may modulate the excessive local immune response by inhibiting TLR2 signaling, thereby promoting the repair of damaged colonic mucosa.

ABSTRACT
The TLR2/NF-κB signaling pathway plays an important role in the pathomechanism of ulcerative colitis (UC); acupuncture and moxibustion can improve the damage in colonic tissues of UC, but the regulatory mechanism remains unknown. This study observed the effect of moxibustion on the TLR2/NF-κB signaling pathway at the Tianshu (ST25) and Qihai (CV6) acupuncture points in the UC rat. The result shows that TLR2, IRAK1, and IKK-b mRNA and protein levels in the colonic mucosa were significantly higher in the UC rats than in the control rats. Herb-partitioned moxibustion reduced the expression of TLR2, IRAK1, and IKK-b mRNA and proteins in the UC rats. Similarly, the expression of NF-κB was significantly increased and IFN-β and IL-10 were significantly decreased in the colonic mucosa of UC rats, but herb-partitioned moxibustion reduced the expression of IFN-β and upregulating the expression of IFN-β and IL-10 significantly. It indicates that herb-partitioned moxibustion can inhibit the expression of multiple signaling molecules of the TLR2 pathway effectively, and it may modulate the excessive local immune response by inhibiting TLR2 signaling, thereby promoting the repair of damaged colonic mucosa.

Mentions: As shown in Figures 12 and 13, NF-κB protein levels in the colonic mucosa were significantly higher in UC rats than in the control rats, as measured by both the total area of staining and the integrated optical density (P < 0.01). Both herb-partitioned moxibustion and SASP treatments were associated with lower NF-κB protein levels in the colonic mucosa of UC rats as indicated by the total area of staining (P < 0.01). NF-κB protein levels were slightly lower in the herb-partitioned moxibustion group than in the SASP group, but the difference was not statistically significant (P > 0.05).
