Cover Story: Connexin 43 (Cx43), an astroglial perisynaptic protein, is important for synaptic transmission and cognition via presynaptic regulation. However, whether it acts by modulating synaptic vesicle release is unknown. Using ultrastructural studies and live imaging of synaptic vesicle recycling, we found that a deficiency of astroglial Cx43 impairs synaptic vesicle distribution and release dynamics, despite the normal development of hippocampal neurons and synapses. Electrophysiological recordings further showed that synaptic vesicle release probability is also reduced and dependent on glutamine supply via the Cx43 hemichannel function. Taken together, we have uncovered a role for astroglial Cx43 in presynaptic function by controlling the rate and probability of synaptic vesicle release, further highlighting its significance in synaptic transmission and efficacy.
