In some cases, the highly calcium-permeable α7-containing (α7∗) nAChRs mediate the increased release of neurotransmitter, but in other cases different nAChR subtypes are involved. PubMed:17009926
Presynaptic and preterminal nicotinic receptors enhance neurotransmitter release, and postsynaptic and nonsynaptic nAChRs mediate excitation as well as activity-dependent modulation of circuits and intracellular enzymatic processes. PubMed:17009926
Activation of presynaptic nAChRs increases the release of many different neurotransmitters (1, 2, 4, 5, 40, 41, 77–83). PubMed:17009926
Presynaptic and preterminal nAChRs increase the release of neurotransmitters in the hippocampus, particularly the main neurotransmitters, GABA and glutamate (41, 78, 81, 97). PubMed:17009926
α7 AChRs can act at the presynaptic, postsynaptic or perisynaptic levels to facilitate the liberation of neurotransmitters, mediate synaptic transmission, or modulate the connections of different neurons by activating diverse second messenger routes [1,19,23–31]. PubMed:22040696
There is good evidence that a6*-nAChRs, in particular, modulate neurotransmitter release in multiple brain regions. PubMed:21787755
For example, Bgt-sensitive a7-nAChRs have been implicated in processes such as vicinal control of neurotransmitter release [7,14], development and maintenance of neurites and synapses [18–20], long-term potentiation [95,96], seizures [97], and neuronal viability/death [21–24]. These intriguing findings underscore the need for further characterization of functional a7-nAChRs. PubMed:21787755
At the cellular level, nAChRs can underlie synaptic responses, neuronal excitability, and neurotransmitter release (Dajas-Bailador and Wonnacott, 2004; Gotti and Clementi, 2004; Hogg et al., 2003) PubMed:28445721
