Visilizumab (Anti-Human CD3E Recombinant Antibody) is a humanized low-Fc receptor binding anti-CD3 monoclonal IgG2 antibody. Visilizumab can be used for ulcerative colitis and Crohn's disease research.
Visilizumab induces dose- and time-dependent apoptosis of lamina propria T cells. Visilizumab-induces apoptosis of lamina propria T cells is dependent on caspase 3 and 8, but not caspase 9 activation and does not involve the Fas/FasL pathway[1].
