Anti-Integrin Therapy For Inflammatory Bowel Disease, S. C. Park, Y. T. Jeen

Journal Articles

© The Author(s) 2018. Published by Baishideng Publishing Group Inc. All rights reserved. In inflammatory bowel disease (IBD), tumor necrosis factor plays an important role in mediating inflammation, but several other pathways are also involved in eliciting an inflammatory response. One such pathway is the invasion of the intestinal mucosa by leukocytes. Leukocytes within the systemic circulation move to sites of inflammation, and blocking this pathway could be an important treatment strategy for IBD. Antiintegrin therapy blocks the action of integrin on the surface of circulating immune cells and endothelial cell adhesion molecules, thereby inhibiting the interactions between leukocytes and …
