An arthritogenic alphavirus uses the α1β1 integrin collagen receptor
La Linn, M., Eble, J. A., Lübken, C., Slade, R. W., Heino, J., Davies, Janet, & Suhrbier, A. (2005) An arthritogenic alphavirus uses the α1β1 integrin collagen receptor. Virology, 336(2), pp. 229-239.
Ross River (RR) virus is an alphavirus endemic to Australia and New Guinea and is the aetiological agent of epidemic polyarthritis or RR virus disease. Here we provide evidence that RR virus uses the collagen-binding α1β1 integrin as a cellular receptor. Infection could be inhibited by collagen IV and antibodies specific for the β1 and α1 integrin proteins, and fibroblasts from α1-integrin-/- mice were less efficiently infected than wild-type fibroblasts. Soluble α1β1 integrin bound immobilized RR virus, and peptides representing the α1β1 integrin binding-site on collagen IV inhibited virus binding to cells. We speculate that two highly conserved regions within the cell-receptor binding domain of E2 mimic collagen and provide access to cellular collagen-binding receptors.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
