Abstract
Host cell entry is the first and most fundamental step of every virus infection and represents a major barrier for zoonotic transmission and viral emergence. Targeting viral entry appears further as a promising strategy for therapeutic intervention. Several cellular receptors have been identified for Lassa virus, including dystroglycan, TAM receptor tyrosine kinases, and C-type lectins. Upon receptor binding, LASV enters the host cell via a largely unknown clathrin- and dynamin-independent endocytotic pathway that delivers the virus to late endosomes, where fusion occurs after engagement of a second, intracellular receptor, the late endosomal/lysosomal resident protein LAMP1. Here, we describe a series of experimental approaches to investigate LASV cell entry and to test candidate inhibitors for their action at this early and decisive step of infection.
