WebbAlthough cholinergic drugs are known to modulate nociception, the role of endogenous acetylcholine in nociceptive processing remains unclear. In the current study, we evaluated the role of cholinergic transmission through spinal β2-subunit-containing nicotinic acetylcholine receptors in the control of nociceptive thresholds. WebbThese processes govern the function of the individual synapses formed by any given neuron, although the underlying cellular and molecular mechanisms have not been fully defined. To determine postsynaptic mechanisms of synaptic specificity, I investigated the role of menin, the product of the MEN1 tumor suppressor gene, in promoting cholinergic …
