However, it is still unclear how EBV accesses and transforms primary epithelial cells. Sixteen samples consisting of primary epithelial cells from the sphenoidal sinus or from tonsils were infected with GFP\u2010tagged recombinant B95.8 EBVs produced in the 293 cell line. The rate of infection was assessed by counting GFP\u2010positive cells and cells expressing viral proteins. Primary epithelial cells from all samples were found to be sensitive to EBV infection but there was a marked interindividual variation among the tested samples (2\u201348% positive cells). This suggests heterogeneity in terms of sensitivity to EBV infection <jats:italic>in vivo<\/jats:italic> and therefore possibly to EBV\u2010associated diseases of the epithelium. The virus showed a preferential tropism for differentiated epithelial cells (p63 negative, involucrin positive). In all cases, infected cells expressed EBV lytic proteins but also the LMP1 protein. The viral tropism for differentiated cells and the permissivity of these cells for virus replication reproduced <jats:italic>in vitro<\/jats:italic> cardinal features of oral hairy leukoplakia. We have identified a source of EBV that shows unusually strong epitheliotropism for primary epithelial cells that will allow detailed analysis of virus\u2010cell interactions during virus infection, replication and virus\u2010mediated transformation. \u00a9 2007 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ijc.22727","type":"journal-article","created":{"date-parts":[[2007,4,6]],"date-time":"2007-04-06T15:48:51Z","timestamp":1175874531000},"page":"588-594","source":"Crossref","is-referenced-by-count":57,"title":["Epstein\u2010Barr virus B95.8 produced in 293 cells shows marked tropism for differentiated primary epithelial cells and reveals interindividual variation in susceptibility to viral infection"],"prefix":"10.1002","volume":"121","author":[{"given":"Regina","family":"Feederle","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bernhard","family":"Neuhierl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Helmut","family":"Bannert","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karsten","family":"Geletneky","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claire","family":"Shannon\u2010Lowe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Henri\u2010Jacques","family":"Delecluse","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,5,25]]},"reference":[{"key":"e_1_2_6_2_2","series-title":"Fields virology","first-page":"2575","author":"Rickinson AB","year":"2001"},{"key":"e_1_2_6_3_2","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM198405103101905"},{"key":"e_1_2_6_4_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V85.3.744.bloodjournal853744"},{"key":"e_1_2_6_5_2","doi-asserted-by":"publisher","DOI":"10.1182\/blood.V89.8.2856"},{"key":"e_1_2_6_6_2","doi-asserted-by":"publisher","DOI":"10.1136\/mp.53.1.37"},{"key":"e_1_2_6_7_2","doi-asserted-by":"publisher","DOI":"10.1128\/JVI.79.2.1296-1307.2005"},{"key":"e_1_2_6_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(88)91604-2"},{"key":"e_1_2_6_9_2","series-title":"Infections with Epstein\u2010Barr virus and human herpes viruses.
