Evidence that OCLN is involved in HCV cell entry

PMID: 19182773 - Ploss et al 2009 - show that human occludin is an essential HCV cell entry factor that is able to render murine cells infectable with HCVpp. Similarly, OCLN is required for the HCV-susceptibility of human cells, because its overexpression in uninfectable cells specifically enhanced HCVpp uptake, whereas its silencing in permissive cells impaired both HCVpp and HCVcc infection.

PMID: 31328852 - Lavie et al 2019 - looked at which residues in OCLN affect hepatitis C virus (HCV) entry. In the context of full-length OCLN, mutation of I279 and W281 residues only partially affected infection and cell surface localization.
