Generation of Marburg virus-like particles by co-expression of glycoprotein and matrix protein

Marburg virus (MARV), the causative agent of a severe hemorrhagic fever, has a characteristic filamentous morphology. Here we report that co-expression of MARV glycoprotein and matrix protein (VP40) in mammalian cells leads to spontaneous budding of filamentous particles strikingly similar to wild-t...

description Marburg virus (MARV), the causative agent of a severe hemorrhagic fever, has a characteristic filamentous morphology. Here we report that co-expression of MARV glycoprotein and matrix protein (VP40) in mammalian cells leads to spontaneous budding of filamentous particles strikingly similar to wild-type MARV. In addition, these particles elicit an immune response in BALB/c mice. The generation of non-replicating Marburg virus-like particles (VLPs) should significantly facilitate the research on molecular mechanisms of MARV assembly and release. Furthermore, VLPs may be an excellent vaccine candidate against Marburg infection.
