Natalizumab 那他珠单抗
产品介绍 | Natalizumab 是一种重组的人源化 IgG4 单克隆抗体,与 α4β1-整联蛋白 (α4β1-integrin) 结合并阻断其与血管细胞粘附分子 1 (VCAM-1) 的相互作用。Natalizumab 可用于复发缓解型多发性硬化症和克罗恩氏病的研究。Natalizumab 也可阻止淋巴细胞进入中枢神经系统,从而防止急性脱髓鞘复发。 |

生物活性 | Natalizumab is a recombinant, humanized IgG4 monoclonal antibody, binds to α4β1-integrin and blocks its interaction with vascular cell adhesion molecule-1 (VCAM-1). Natalizumab can be used for the treatment of relapsing remitting multiple sclerosis and Crohn's disease. Natalizumab is also the first targeted therapy which blocks an essential mechanism for lymphocyte entry to the CNS and thus prevents acute demyelinating relapses. |
体外研究 |
Natalizumab, a recombinant, humanized antibody, binds to α4β1-integrin and blocks its interaction with VCAM-1. 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. 西域 has not independently confirmed the accuracy of these methods. They are for reference only. |
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 1 mg/kg to 6 mg/kg. 西域 has not independently confirmed the accuracy of these methods. They are for reference only. |
