Fatty acids that occur naturally in the brain may reduce inflammation associated with multiple sclerosis, a Stanford University study suggests, a finding that may lead to a new approach to treat the disease. Researchers showed that injecting high doses of the fatty acids, or lipids, into paralyzed mice with MS symptoms reduced inflammation in their brains and allowed them to regain movement within 24 to 36 hours, said Lawrence Steinman, an author of the paper published today in the journal Science Translational Medicine.
