Menthol Binding and Inhibition of α7-Nicotinic Acetylcholine Receptors
Menthol is a common compound in pharmaceutical and commercial products and a popular additive to cigarettes. The molecular targets of menthol remain poorly defined. In this study we show an effect of menthol on the α7 subunit of the nicotinic acetylcholine (nACh) receptor function. Using a two-electrode voltage-clamp technique, menthol was found to reversibly inhibit α7-nACh receptors heterolog...
متن کاملTherapeutic Potential of α7 Nicotinic Acetylcholine Receptors.
Progress in the fields of neuroscience and molecular biology has identified the forebrain cholinergic system as being important in many higher order brain functions. Further analysis of the genes encoding the nicotinic acetylcholine receptors (nAChRs) has highlighted, in particular, the role of α7 nAChRs in these higher order brain functions as evidenced by their peculiar physiologic and pharma...
متن کاملRhesus monkey α7 nicotinic acetylcholine receptors: Comparisons to human α7 receptors expressed in Xenopus oocytes
An α7 nicotinic acetylcholine receptor sequence was cloned from Rhesus monkey (Macaca mulatta). This clone differs from the mature human α7 nicotinic acetylcholine receptor in only four amino acids, two of which are in the extracellular domain. The monkey α7 nicotinic receptor was characterized in regard to its functional responses to acetylcholine, choline, cytisine, and the experimental α7-se...
متن کاملGalantamine promotes adult hippocampal neurogenesis via M₁ muscarinic and α7 nicotinic receptors in mice.
Galantamine, an inhibitor of acetylcholinesterase, promotes hippocampal neurogenesis, but the exact mechanism for this is not known. In the present study, we examined the mechanisms underlying the effects of acute galantamine on neurogenesis in the mouse hippocampus. Galantamine (3 mg/kg) increased the number of 5-bromo-2'-deoxyuridine (BrdU)-positive cells in the subgranular zone of the dentat...
متن کاملα7-Containing and non-α7-containing nicotinic receptors respond differently to spillover of acetylcholine.
We explored whether nicotinic acetylcholine receptors (nAChRs) might participate in paracrine transmission by asking if they respond to spillover of ACh at a model synapse in the chick ciliary ganglion, where ACh activates diffusely distributed α7- and α3-containing nAChRs (α7-nAChRs and α3*-nAChRs). Elevating quantal content lengthened EPSC decay time and prolonged both the fast (α7-nAChR-medi...
