The pseudoenzyme CPT1C is able to sense changes in intracellular malonyl-CoA levels caused by nutrients or energy stress and regulate late endosomes/lysosomes anterograde transport, necessary for proper axon growth.
Quasi-enveloped hepatitis A virions undergo clathrin-mediated endocytosis, followed by ALIX-dependent trafficking to lysosomes where the quasi-envelope is degraded, triggering uncoating of the RNA genome in association with lysosomal membrane rupture.
Sterol kinetics and cell-based assays reveal a heretofore unknown step in cholesterol trafficking through the endolysosomal compartment, involving a direct functional interaction between NPC2 and lysosbisphosphatidic acid.
Multivesicular bodies deliver long-range retrograde nerve growth factor (NGF) signals and serve as essential signaling and sorting platforms in the cell soma, and multivesicular body (MVB) cargoes dictate their vesicular fate.
A novel microscopy-based assay shows that dendritic cells encountering pathogenic stimuli form increased complexes of specific SNARE proteins, driving release of large amounts of inflammatory cytokines.
