Viral protein determinants of Lassa virus entry and release from polarized epithelial cells.

abstract：UNLABELLED:Demonstrating direct interactions between host and virus proteins during infection is a major goal and challenge for the field of virology. Most protein interactions are not binary or easily amenable to structural determination. Using infectious preparations of a polerovirus (Potato leafroll virus [PLRV]) an...
