Integrin alpha9beta1 is widely expressed on smooth muscle, epithelial cells, and highly and specifically expressed on neutrophils. VCAM-1 is one of the effective ligands for the integrin alpha9beta1. This interaction mediates the neutrophile migration on VCAM-1 and extravasation of neutrophils at sites of acute inflammation.
