Identifying gp85- regions involved in Epstein- Barr virus binding to Blymphocytes.

Epstein–Barr virus lacking glycoprotein gp85 cannot infect B-cells and epithelial cells. The gp85 belongs to the molecular complex required for virus invasion of B-lymphocyte or epithelial cells. Moreover, there is evidence that gp85 is necessary for virus attachment to epithelial cells. Thirty-six...

The gp85 belongs to the molecular complex required for virus invasion of B-lymphocyte or epithelial cells. Moreover, there is evidence that gp85 is necessary for virus attachment to epithelial cells. Thirty-six peptides from the entire gp85-sequence were tested in epithelial and lymphoblastoid cell line binding assays to identify gp85-regions involved in virus–cell interaction. Five of these peptides presented high binding activity to Raji, Ramos, P3HR-1, and HeLa cells, but not to erythrocytes; Raji-cell affinity constants were between 80 and 140 nM. Of these five peptides, 11435 (181TYKRVTEKGDEHVLSLVFGK200), 11436 (201TKDLPDLRGPFSYPSLTSAQ220), and 11438 (241YFVPNLKDMFSRAVTMTAAS260) bound to a 65 kDa protein on Raji-cell surface. These peptides and antibodies induced by them (recognising live EBV-infected cells) inhibited Epstein–Barr virus interaction with cord blood lymphocytes. It is thus probable that gp85-regions defined by peptides 11435, 11436, and 11438 are involved in EBV invasion of B-lymphocytes.application/pdfhttps://doi.org/10.1016/j.bbrc.2004.04.177ISSN: 0006-291XEISSN: 1090-2104https://repository.urosario.edu.co/handle/10336/27839engElsevier229No. 1221Biochemical and Biophysical Research CommunicationsVol. 319Biochemical and Biophysical Research Communications, ISSN: 0006-291X ; EISSN: 1090-2104, Vol.319, No.1 (18 June 2004); pp. 221-229https://www.sciencedirect.com/science/article/abs/pii/S0006291X04009453Restringido (Acceso a grupos específicos)http://purl.org/coar/access_right/c_16ecBiochemical and Biophysical Research Communicationsinstname:Universidad del Rosarioreponame:Repositorio Institucional EdocUREBVgp85Raji-cell binding peptidesHABPsIdentifying gp85- regions involved in Epstein- Barr virus binding to Blymphocytes.Identificación de las regiones gp85- implicadas en la unión del virus de Epstein-Barr a los linfocitos B.articleArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501Urquiza, MauricioSuarez, JorgeLopez, RamsesVega, ErikaPatiño, HelenaGarcia, JavierPatarroyo, Manuel A.Guzman, FannyPatarroyo, Manuel E.10336/27839oai:repository.urosario.edu.co:10336/278392022-05-02 07:37:21.936144https://repository.urosario.edu.coRepositorio institucional EdocURedocur@urosario.edu.co
