Quantification of endocannabinoid levels in EAE female
C57BL/6
mice treated either with vehicle or WOBE437. (A) 2-AG and (B) AEA
were quantified in brain, cerebellum, lumbar SC, and plasma at the
peak of the disease (4–6 days after onset; average harvest
day was 5 for both groups). (C) 2-AG and (D) AEA were quantified in
brain, cerebellum, lumbar SC, and plasma at the chronic/remission
stage (20 days after onset). 2-AG and AEA were quantified using LC-MS/MS,
and values were normalized to the tissue amount (g) or volume (mL).
Vehicle (DMSO) and WOBE437 were given i.p. (20 μL) starting
at the disease onset (day 1). Sample size numbers (indicated as vehicle/WOBE437)
were the following: (A, B) brain n = 8/9, cerebellum n = 8/9, lumbar SC n = 5/6, and plasma n = 8/9; (C) brain n = 21/17, cerebellum n = 20/15, lumbar SC n = 13/7, and plasma n = 21/17; (D) brain n = 21/17, cerebellum n = 20/15, lumbar SC n = 13/7, plasma n = 22/22. Data show mean ± SD. Statistical differences
were determined using the Mann–Whitney test. *, p < 0.05 compare to vehicle group; if significant, then a percentage
of increase is reported above.
