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.
An important rice reovirus hijacks exosomes to traverse the apical plasmalemma into saliva-stored cavities in the salivary glands of insect vectors, facilitating viral horizontal transmission into rice phloem.
Exosomes from cancer-associated fibroblasts enhance the "Warburg effect" in tumors and contain de novo metabolites that can contribute to the entire compendia of central carbon metabolism within cancer cells.

Quantitative 3D lattice light sheet microscopy of unperturbed cells combined with electron tomography and acute loss of function experiments reveals how dynamic ESCRT-III/Vps4 assemblies succeed in reverse membrane budding on endosomes.
Condensation of cytosolic protein YBX1 into processing bodies reveals mechanisms for efficient and selective sorting of proteins and their cognate microRNAs into exosomes.

A cell-free reaction that reconstitutes the selective sorting of a miRNA into exosomes reveals an RNA-binding protein, YBX1, as a critical sorting factor.

Kazrin, a protein widely expressed in vertebrates whose depletion causes defects in cell adhesion and migration, is recruited to early endosomes and promotes dynein/dynactin-dependent traffic of endocytosed cargo to the recycling endosomes.
The combination of NSCs with NSC-derived exosomes ameliorated the injury of brain tissue including cerebral infarction, neuronal death, and glial scarring, and promoted the recovery of motor function.
A combination of spatial proteomic and autophagic flux approaches was used to reveal the landscape of turnover of damaged lysosomes, demonstrating a key role for the autophagy receptor TAX1BP1 and its associated kinase TBK1 in both HeLa cells and iNeurons.
