Relevance Integrins are heterodimeric cell surface receptors composed of alpha and beta subunits, which mediate cell-cell and cell-extracellular matrix attachments. Integrin alpha 2b (CD41) and integrin ß3 (CD61) associate to form the heterodimer integrin a2bß3 (CD41/CD61; GPIIb/IIIa), a fibronectin receptor expressed in platelets. M148 prevents aggregation of platelets. Used for imaging and therapy of thrombi. M148 binds to some medulloblastoma and neuroblastoma cells and rhabdomyosarcoma and certain other solid tumours. No binding is observed to marrow constituents other than platelets and megakaryocytes. Aberrant integrin expression has been found in many epithelial tumours. Changes in integrin expression have been shown to be important for the growth and early metastatic capacity of melanoma cells.
