Natalizumab may also be used totreat bowel condition called Crohn’s disease (CD). This is used when it ismoderate to severe and keeps coming back. This helps prevent the immune systemfrom causing inflammation or swelling within your bowels.

Howdoes Natalizumab work?

Natalizumab binds to a specific receptor knownas an integrin. It is found on the surface of white blood cells calledleucocytes. The leucocytes are involved in producing inflammation. It isbelieved that brain lesions in multiple sclerosis occur when certain leucocytesmove out of the blood and into the brain. Blocking the integrin receptors onthe leucocytes stops them from moving from the blood into the brain. This lessensinflammation in the brain and decreases the enlargement of brain lesions. Thatit may result in the nerve damage caused by multiple sclerosis.
