Zusammenfassung

Environmental factors and genetic predisposition influence the individual risk to develop multiple sclerosis (MS). Preclinical results in animal models of MS, such as experimental autoimmune encephalomyelitis (EAE), prove a significant contribution of the corpuscular and plasmatic coagulation system for the severity of MS. It was recently shown that key molecules of the coagulation cascade, such as fibrinogen, thrombin and factor XII can influence neuroinflammatory disorders such as MS. The inhibition of both fibrinogen and factor XII led to a significantly improved disease course in animal models. Furthermore, in patients suffering from MS a dysregulation of diverse coagulation factors was demonstrated. The precise role of these changes for the pathogenesis of MS remains to be clarified. Nonetheless, the identification of molecular mechanisms between inflammation and the coagulation cascade might provide completely new perspectives for the therapy of MS; however, as most of the currently available data were obtained from animal models, this knowledge must be interpreted with an adequate degree of caution.
