Global phosphoproteomic analysis in nerve terminal during exocytosis reveals 252 uniquely regulated phosphosites, highlighting complex regulation of active zone proteins at multiple sites and the role of specific kinases/phosphatases.
Live cell imaging shows that the cAMP-sensor Epac2, a target of major antidiabetic drugs, is central to fusion pore control during insulin granule exocytosis.
Analysis of neurons that lack the two neuronal dynamins, dynamin 1 and 3, demonstrates a pathway of synaptic vesicle reformation that does not require these two dynamins or clathrin-dependent budding.
Within minutes after an abrupt increase in membrane tension, yeast cells reduce their membrane tension by modulating their rate of endocytosis and exocytosis, and adapt their endocytic actin machinery.

To maintain the filtration barrier, slit diaphragms are cleansed by rapid cycles of raft-mediated endocytosis, while dynamin-dependent endocytosis prevents lateral diffusion of slit diaphragm protein.
Single synaptic vesicle imaging shows that kinetically distinct endocytic pathways are differentially regulated by calcium and temperature, and influence the fidelity of synaptic vesicle protein retrieval.
Optogenetics has revealed that synaptic vesicles can be recycled extremely rapidly in nematodes, indicating that existing models for how synapses 'reload' may need to be revised.
The interplay between the Flower Ca2+ channel and PI(4,5)P2 spatiotemporally couples synaptic vesicle exocytosis to activity-dependent bulk endocytosis and synaptic vesicle reformation from bulk endosomes.
A high-resolution approach for monitoring dry mass and the density of that dry mass on a single-cell level is developed and used to reveal that mammalian cells can lose components in mitosis due to lysosomal exocytosis.
