FAE and 2-AG levels in the ileum and distal colon of saline-treated (control) or LPS (100 µg·kg−1, i.p.)-treated mice pretreated with AM3506 (0.5 mg·kg−1, i.p.) or its vehicle. AM3506 treatment enhanced AEA levels in the ileum (A), but not the colon (B) of LPS-treated mice. There were no significant differences in the levels of PEA (C and D), OEA (E and F) or 2-AG (G and H) in the ileum (C, E and G) or colon (D, F and H). *P < 0.05 compared with control; n = 3–10 per group.
