As a result,leukocyte migration into brain tissue is inhibited, reducing inflammation and preventing the formation of lesions.Natalizumab may also inhibit ongoing central nervous system (CNS) inflammation, mediated by leukocytes already present in the CNS, by interrupting the interactions between α4-integrin-expressing leukocytes and extracellular matrix proteins such as fibronectin and osteopontin. 体内研究 Natalizumab binds rapidly and with high affinity to α4-integrin.Maximal binding (≥80% saturation), measured in vitro on isolated lymphocyte membranes, occurred 24 hours after intravenous (IV) doses of natalizumab 1mg/kg to 6mg/kg. |
