The wild-type baculovirus Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) infects a range of mammalian cell types in vitro but does not replicate in these cells. The current study investigated the in vivo effect of AcMNPV in the mouse model of liver cirrhosis induced by the mutagen dimethylnitrosamine. Intraperitoneal injection of AcMNPV induced an immune response. The baculovirus was taken up by the liver and spleen where it suppressed liver injury and fibrosis through the induction of interferons. This study presents the first evidence of the feasibility of using baculovirus to treat liver cirrhosis. Gene Therapy (2008) 15, 990-997;
Antigenic analysis of Inoue-Melnick virus, formerly called SMON virus, showed that isolates from patients with subacute myelo-optico-neuropathy (SMON) in Japan, thus far tested, belonged to a single antigenic type (type 1). However, Inoue-Melnick virus isolates obtained so far in the United States chiefly from patients with multiple sclerosis could be classified into three types: type 1, type 2, and an intermediate type. At the present state of knowledge, the virus has not been proven to be the causative agent of disease, hence its provisional designation as IMV.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
