Encephalomyocarditis Virus Entry Unveiled
ABSTRACT Picornaviruses are a widespread group of pathogens that can cause diverse pathologies. Pathogenesis is thought to be driven by the tissue-specific tropisms displayed by these viruses. For example, many picornaviruses can infect the heart and cause viral myocarditis. Encephalomyocarditis vir...

Encephalomyocarditis virus (EMCV) is a rodent pathogen that causes myocarditis in rodent models and has been used to model this biology.

Since the extracellular domain but not the enzymatic activity or intracellular domain is required for infection, the data suggest that ADAM9 acts as an entry receptor or at an early step in the process, shedding light on the biology of EMCV infection and pathogenesis.Sara CherryAmerican Society for MicrobiologyarticleentryreceptorvirusMicrobiologyQR1-502ENmBio, Vol 10, Iss 2 (2019) |
