Regulating the Balance of Th17/Treg via Electroacupuncture and Moxibustion: An Ulcerative Colitis Mice Model Based Study

Figure 3

Toll-like receptor (TLR) 2 and TLR4 were detected in the colon by the immunohistochemical method. Compared with the control group (a, e), the intestinal TLR2 and TLR4 expression in normal in model group have increased (b, f). After acupuncture (c, g) or moxibustion (d, h) treatment, the expressions of TLR2 and TLR4 have been reduced. The average IOD was obtained by analyzing TLR2 (i) and TLR4 (j) immunohistochemistry staining in five random fields of each slide. Compared with electroacupuncture group, the OD level of TLR2 and TLR4 in moxibustion group is lower. ; (magnification, 200x, and scale bar = 100 μm).
