Although it has been 2021-02-11 · In addition to acetylchonline, cholinergic receptors are also sensitive to two specific types of drugs, namely nicotine and muscarine. The receptors are consequently divided into two subcategories or types, namely nicotinic receptors and muscarinic receptors, depending upon which drug affects the specific receptor. In rodents, pharmacological blockade of either hippocampal nicotinic receptors or M1 muscarinic receptors by local drug injections in rats impairs memory performance in 8-arm radial maze tasks (Ohno et al., 1993, 1994) and direct injection of scopolamine into the dorsal hippocampus impairs encoding of spatial information in the Morris water maze-task (Blokland et al., 1992). More than one-third of all people are estimated to experience mild to severe cognitive impairment as they age. Acetylcholine (ACh) levels in the brain diminish with aging, and nicotinic ACh receptor (nAChR) stimulation is known to enhance cognitive performance. The prefrontal cortex (PFC) is involved in a range of cognitive functions and is thought to mediate attentional focus.

Nicotinic receptors (nAhRs) are a group of cholinergic receptors that also interact with nicotine in tobacco. They form pores through the cell membrane of the post-ganglionic nerves. As nicotinic receptors serve as ligand-gated ion channels, they mediate the fast transmission of nerve impulses at synapses.

Nicotinic acid has been used for several decades to treat dyslipidemia. In mice, the lipid-lowing effect of nicotinic acid is mediated by the Gi coupled receptor PUMA-G. In humans, high (GPR109A) and low (GPR109B) affinity nicotinic acid receptors have been characterized. Here we identify monomethylfumarate as a GPR109A agonist.

General methods are needed for synthesis of their guanidine and aminoguanidine metabolites so they may be used as analytical standards and for evaluation of nicotinic receptor potency.

I recettori nicotinici (abbreviati in nAChR a causa del nome inglese Nicotinic acetylcholine receptors) sono recettori colinergici che formano canali ionici attivati da ligando nella membrana plasmatica di alcuni neuroni e nella porzione postsinaptica della giunzione neuromuscolare.
