Infliximab: mechanism of action

The active substance in infliximab is a monoclonal antibody.1,2 A monoclonal antibody is an antibody (a type of protein) which recognises and binds to a specific structure (called an antigen) in the body1,2

The antigen that infliximab recognises is the cytokine (a messenger protein) tumour necrosis factor alpha (TNF-ɑ)1,2

Infliximab is a chimeric antibody, where the antigen-binding portion is of murine origin, whereas the constant region is of human origin3,4

TNF-alpha is involved in driving inflammation and is found at high levels in patients with the immune-mediated inflammatory diseases that infliximab is used to treat. By blocking TNF-ɑ, infliximab improves inflammation and other symptoms of those diseases1,2

Watch our video to learn how infliximab inhibits the functional activity of TNF-ɑ
