Receptors nicotinic-cholinergic

Nicotinic Receptor Agonists. There has been significant activity in the development of muscarinic cholinergic receptor agonists for dementia. In addition, agents that interact with nicotinic cholinergic receptors may also have therapeutic value. Nicotinic receptors have been reported to be... [Pg.99]

Isoreceptors Different receptor proteins that recognise and bind the same neurotransmitter (e.g., muscarinic and nicotinic cholinergic receptors). [Pg.244]

Muscle-relaxant A drug that relaxes skeletal (voluntary) muscle either directly by blocking nicotinic cholinergic receptors or indirectly through the activation of inhibitory spinal cord interneurons. [Pg.245]

Acetylcholine. Most of the acetylcholine in the basal ganglia is found in the striatum, as the neurotransmitter of the large spiny interneurons, which account for about 3% of all striatal neurons. Both muscarinic and nicotinic cholinergic receptors are found in the striatum. Postsynaptic muscarinic receptors may inhibit transmitter release from... [Pg.764]

Abstract The discovery that mammalian brain expresses the mRNAs for nine different nicotinic cholinergic receptor subunits (a2-a7, p2-p4) that form functional receptors when expressed in Xenopus laevis oocytes suggests that many different types of nicotinic cholinergic receptors (nAChRs) might be expressed in the mammalian brain,. Using an historical approach, this chapter reviews some of the... [Pg.85]

Adolescent nicotine exposure results in pronounced and persistent nicotinic cholinergic receptor upregulation in male rats and hippocampal cell damage in females (Trauth et al. 1999). During and following nicotine treatment as adolescents, female rats show impaired rearing and locomotor activity, whereas males are unaffected. On the other hand, improved performance was observed in passive avoidance (Trauth et al. 2000). [Pg.272]

All of these results are consistent with the hypothesis that the withdrawal severity (numbers of withdrawal signs) reflects chronic overstimnlation of nicotinic cholinergic receptors followed by rednced stimnlation. [Pg.412]

Nicotinic cholinergic receptors are located on cells that release a wide variety of transmitters (see chapter by Barik and Wonnacott, in this volume), so that nicotine interacts with multiple neurochemical pathways. The roles of cholinergic, dopaminergic, and endogenous opioid systems in physical dependence and withdrawal have been most thoroughly studied and documented. Research on the role of other transmitters and neurochemical mechanisms is rather scattered. Overall, however, research with rodent models of physical dependence has provided a wealth of potential targets for experimental treatments to aid smoking cessation. [Pg.418]
