Identification of cell moieties involved in viral binding and internalization is essential since their expression would render a cell susceptible. Further steps that allow the uncoating of the viral particle at the right subcellular localization have been intensively studied. These ?entry? steps could determine cell permissiveness and often define tissue and host tropism. Therefore applying the right and, when possible, straightforward experimental approaches would shorten avenues to the complete knowledge of this first and key step of any viral life cycle. Mammarenaviruses are enveloped viruses that enter the host cell via receptor-mediated endocytosis. In this chapter we present a set of customized experimental approaches and tools that were used to describe the entry of Junín virus (JUNV), and other New World mammarenavirus members,into mammalian cells.Key words Virus, Receptor recognition, Endocytosis pathways
