Schematic of the seven heterodimeric integrin adhesion receptors expressed by eosinophils. Functions and ligands assigned to integrins have been deduced in various assays employing eosinophils. Asterisks represent subunits that contain the I (Insert)-domain. Subunits that are underlined contain the I-like domain. ICAM, intercellular adhesion molecule; MAdCAM-1, mucosal addressin cell adhesion molecule-1; FG, fibrinogen; LN, laminin; VCAM, vascular cell adhesion molecule; VN, vitronectin.
