NettetAbstract. Integrin α 5 β 1 is a major fibronectin receptor critical for cell migration. Upon complex formation, fibronectin and α 5 β 1 undergo conformational changes. While this is key for cell-tissue connections, its mechanism is unknown. Here, we report cryo–electron microscopy structures of native human α 5 β 1 with fibronectin to 3 ... NettetImportantly, immune cell recruitment to the intestine is a target of drugs designed for the therapy of IBD. 17 One of them is the anti-β7 integrin antibody etrolizumab. 18 It is considered to interfere with α4β7 integrin-dependent gut homing of T cells and to additionally block T cell retention in the inflamed mucosa via disruption of the …
