VERFAHREN ZUR VERHINDERUNG EINER VIRUS-ZELLE- FUSION DURCH HEMMEN DER FUNKTION DES FUSIONSINITIIERUNGSBEREICHS IN RNA-VIREN MIT KLASSE-I-MEMBRANFUSOGENEN HÜLLPROTEINEN

摘要

The present invention relates to a method of preventing or inhibiting viral infection of a cell and/or fusion between the envelope of a virus and the membranes of a cell targeted by the virus (thereby preventing delivery of the viral genome into the cell cytoplasm, a step required for viral infection). The present invention particularly relates to the families of RNA viruses, including the arenaviruses, coronaviruses, filoviruses, orthomyxoviruses, paramyxoviruses, and retroviruses, having Class I membrane fusion proteins as the fusion proteins that mediate this fusion process. The present invention provides for a method of identifying a conserved motif or domain called the fusion initiation region (FIR) in these viruses. The present invention further provides for methods of preventing infection by such viruses, by interfering with their FIR. The present invention further provides for methods of treatment and prophylaxis of diseases induced by such viruses.
