Action potential-independent spontaneous miniature neurotransmitter release has important physiological functions such as regulation of dendritic protein expression and maintenance of spines in glutamatergic synapses1, two.Bulevirtide Despite the fact that `minis’ happen without extracellular Ca2+ the majority of spontaneous release beneath physiological conditions is Ca2+-dependent (e.g. refs.three, 4).

In contrast, VGCCs have been reported to not be involved in triggering spontaneous glutamate release, because the broad non-specific inorganic VGCC blocker Cd2+ (5000 M) failed to regularly lessen the frequency of miniature excitatory postsynaptic currents (mEPSCs) (e.g. refs. 8, 9). This distinction in between spontaneous GABA and glutamate release is paradoxical, since the mechanisms of evoked release are broadly comparable amongst inhibitory.
