Bottom Line: Clinical symptoms in EAE animals were significantly decreased (P<0.05) as compared to control ones.In addition, the level of the TNF- was significantly decreased following CoQ10 administration versus IL-10.The ratio of TH1/TH2 interleukins in treated animals was significantly less than that in non-treated animals (P<0.01).

ABSTRACT

Background: Multiple sclerosis (MS) is known as a progressive central nervous system inflammatory disease. Certain factors, such as interleukins, inflammatory cells, and oxidative stress are supposed to involve in MS etiology. Because of the important role of oxidative stress, antioxidant therapy for MS has received more attention. Although coenzyme Q10 (CoQ10) acts as an antioxidant, there is a lack of enough research on its effects on MS. Therefore, the present research was designed.

Methods: C57BL/6 female adult mice (n = 30) were used in this study. The animals were randomly divided into trial and control groups. To induce MS, routine procedure for experimental autoimmune encephalomyelitis (EAE) was used, and scoring was performed based on clinical signs. By detecting score one, CoQ10 administration was started (10 mg/kg/three weeks). By using ELISA and real-time PCR, the brain levels of TNF-, IL-10, IL-4, and IL-12 were studied. Statistical tests were used to analyze the data and the P value less than 0.05 was considered to be significant.

Results: Clinical symptoms in EAE animals were significantly decreased (P<0.05) as compared to control ones. In addition, the level of the TNF- was significantly decreased following CoQ10 administration versus IL-10. The ratio of TH1/TH2 interleukins in treated animals was significantly less than that in non-treated animals (P<0.01).

Conclusion: Our findings showed that CoQ10 is capable of suppressing the inflammatory pathway of MS.

Mentions: Histological study. EAE caused a significant demyelination in a certain area of the brain such as corpus callosum. The comparison of EAE group with EAE + CoQ10 group (42.56 ± 37.12% and 31.19 ± 39.14%, respectively) significantly showed less demyelination in the second group (P<0.05) (Fig. 1). The result from the animals that received only sesame oil (vehicle sham group) significantly demonstrated less demyelination compared and EAE and EAE + CoQ10 groups (P<0.05) (Fig. 2).
