Anti-integrin as novel drug-discovery targets: potential therapeutic and diagnostic implications.
The role of integrin and extracellular matrix proteins in various pathological processes (including angiogenesis, thrombosis, apoptosis and cell migration and proliferation), leading to both acute and chronic disease states (e.g. ocular diseases, metastasis, unstable angina, myocardial infarction, stroke, osteoporosis, a wide range of inflammatory diseases, vascular remodeling and neurodegenerative disorders) has been recently documented. A key success in this field is evident from the potential role of the platelet GPIIb/IIIa (alphaIIbbeta3) integrin in the prevention, treatment and perhaps diagnosis of various thromboembolic disorders. Additionally, progress has been shown in the development of leukocyte alpha4beta1 antagonists for various inflammatory indications and alphav integrin antagonists for angiogenesis and vascular-related disorders. However, the exact modes of action of certain integrin antagonists are still not fully clear. Integrin antagonists in clinical or pre-clinical development are expected to be used as a stand-alone therapy or, better, as an adjunct to other pharmacotherapy, radiotherapy or interventional procedures.
