Active zone release probability is correlated with calcium channel density and calcium influx at single release sites, with release strength increasing in an activity-dependent manner during synapse maturation.
A combination of tethered diffusion of release-ready synaptic vesicles and vesicle-vesicle fusion supports neurotransmitter release at the presynaptic active zone of sensory synapses.
Spontaneous fusion of vesicles at synapses is regulated independently of fusion triggered by action potentials, adding to evidence that the two types of fusion have distinct functions.
Local elimination of acetylcholine synthesis in habenular neurons demonstrates a key role for vesicular synergy and neurotransmitter co-release in nicotine dependence.
The vesicular Ca2+ sensor synaptotagmin-1 regulates both fast phasic and slow tonic glutamate release at ribbon synapses of rod and cone photoreceptor cells.
Immune cell motility and vascular response are imaged in vivo and label free in the CNS for the first time, using high-resolution phase-contrast adaptive optics retinal imaging.
A binary cell fate decision to be or not to be stomata is regulated by multiple peptide ligands, each triggering a unique subcellular dynamics of their shared receptor.
Real-time monitoring of oxytocin-loaded vesicles and synaptic actin dynamics in zebrafish reveal that Slit3-Robo2-Cdc42 signalling maintains steady-state levels of mature oxytocin neuropeptide readily primed to be secreted upon physiological demand.
