PRMT7-mediated SHANK2 methylation regulates breast cancer metastasis by activating endosomal FAK signals, and may provide potential clues for tumour metastasis treatment strategies.
BDNF-regulated deployment of Rab10 to the distal axon regulates retrograde propagation of neurotrophic signalling, providing a flexible mechanism to fine-tune the communication between the synapse and the cell body of neurons, as well as novel therapeutic targets for neurodegeneration.
Cells package active receptors in endosomes at fairly constant amounts and can determine different cell-fate decisions by regulating the number and lifetime of receptor packages.
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.
CapZ controls actin filament density around immature early endosomes via its C-terminal domain to facilitate the homotypic fusion of the endocytic vesicles, and it functions as a scaffold protein via its N-terminal domain to recruit RAB5 effectors to early endosomes.
Sorting nexin 9, a membrane curvature inducing protein, creates a distinct environment within clusters of the co-receptor CD28 and thereby allows T cell activation to proceed to a successful outcome.

Different dynorphins, which signal similarly from the cell surface, can differentially localize G protein-coupled receptors to specific subcellular compartments and cause divergent receptor fates and distinct spatiotemporal patterns of signaling.

A novel, inexpensive, easy-to-use method to analyse traffic along the endosomal pathway in mammalian cells shows that there is coordination between Rab conversion and acidification, but almost none between Rab conversion and recycling.
Combining live imaging and advanced electron microscopy gives insights into the structural integrity of the nematode epidermis and its intimate connection with the extracellular matrix.
