Flavivirus-infected cells release virus particles that contain variable numbers of precursor membrane (prM) protein molecules at the viral surface. Consequently, antibodies are produced against the prM protein. These antibodies have been shown to activate the infectious potential of fully immature flavivirus particles in vitro. Here, we provide in vivo proof that prM antibodies render immature WNV infectious. Infection with antibody-opsonized immature WNV particles caused disease and death of mice, and infectious WNV was found in the brains and sera.", }
