Intracellular protein trafficking pathways are hijacked by viruses at various stages of viral life-cycle. Heterotetrameric adaptor protein complexes (APs) mediate vesicular trafficking at distinct intracellular sites and are essential for maintaining the organellar homeostasis. In the present study, we studied the effect of AP-1 and AP-3 deficiency on flavivirus infection in cells functionally ...

Intracellular bacterial pathogens replicate within eukaryotic cells and display unique adaptations that support key infection events including invasion, replication, immune evasion, and dissemination. From invasion to dissemination, all stages of the intracellular bacterial life cycle share the same three-dimensional cytosolic space containing the host cytoskeleton. For successful infection and...

Legionella pneumophila is an intracellular pathogen that modulates the biogenesis of its phagosome to evade endocytic vesicle traffic. The Legionella-containing phagosome (LCP) does not acquire any endocytic markers and is remodeled by the endoplasmic reticulum during early stages. Here we show that intracellular replication of L. pneumophila is inhibited in gamma interferon (IFN-gamma)-activat...
