Anti-inflammatory effect of cannabinoid agonist WIN55, 212 on mouse experimental colitis is related to inhibition of p38MAPK

Figure 6 Representative figures of the expression of cannabinoid receptor type 1 and type 2 receptors in mouse colon by immunohistochemistry staining, which are from 4 separate experiments with similar results. A: Expression of cannabinoid (CB)1 receptors; B: Expression of CB2 receptors; (magnification × 400, respectively). The expressions of CB1 receptor in the colonic epithelial cells and CB2 receptor in the submucosal immune cells are marked by arrows and presented as positive results with brown-yellow staining.
