Natalizumab - #BF6015

Natalizumab (AN100226; BG00002) is a humanized monoclonal IgG4 antibody inhibitor that selectively targets α4 integrin (CD49d). It blocks the interaction of integrins such as α4β1 (VLA-4) with vascular cell adhesion molecule VCAM-1, intercellular adhesion molecule ICAM-1, and fibronectin by competitively binding to the α4 subunit. Natalizumab inhibits the adhesion, retention, and transendothelial migration of immune cells (such as CD4+ T cells), reducing the infiltration of inflammatory cells into the central nervous system or lesion sites, thus exerting anti-inflammatory and immunomodulatory activity. Natalizumab is used in the study of relapsing-remitting multiple sclerosis (RRMS) and also has applications in the study of autoimmune or inflammation-related diseases such as Crohn's disease, B-cell lymphoma, and non-infectious uveitis. Natalizumab can also prevent lymphocytes from entering the central nervous system, thereby preventing acute demyelinating relapses.
