The integrin alphavbeta6, a receptor for fibronectin, vitronectin, tenascin and TGF-beta latency-associated peptide (LAP), is not detectable on normal oral epithelium but is neo-expressed in oral squamous cell carcinomas (OSCC) and epithelial dysplasia.
The integrin alphavbeta6 is a fibronectin receptor whose expression is not detectable on normal oral epithelium but is increased significantly in healing and in oral epithelial dysplasia and oral squamous cell carcinoma, suggesting it may promote changes associated with tumor development.
