We investigated the effect of cholesterol removal by MβCD in synaptic vesicle recycling at motor nerve terminals of the frog neuromuscular junction. Our data shows that membrane cholesterol acts on the modulation of synaptic vesicle cycle and seems to be essential for the balance between KCl-evoked and spontaneous release. In addition, we provide evidences that deregulation of cholesterol affects synaptic vesicle biogenesis with consequences for increased transmitter packing.
