Cholinergic System and Neuroinflammation: Implication in Multiple Sclerosis

In the present review we summarize the evidence indicating the correlation between nervous system dysfunction in MS, with inflammation and cholinergic system alterations. Experiments performed in MS animal models and analyses on biological fluids from MS patients such as blood, serum and cerebrospinal fluid suggest that cholinergic alterations may contribute to the dysregulated inflammatory processes of MS. Many current therapeutic approaches in MS are based on anti-inflammatory drugs. We also discuss how the use of cholinesterase inhibitors or ACh mimetics may represent a new interesting therapeutic approach in MS.
