The small GTPase Arf6 plays a role in setting the size of the readily releasable pool of synaptic vesicles and in the definition of the recycling route for endocytosed vesicles.
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.
A novel regulatory step in the endocytic pathway, which occurs post-internalization, takes place at the trans-Golgi network and involves the arrestin-related protein Rod1 and the ubiquitin ligase Rsp5.

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.
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.
