释义 | BETA Examples of nicotinicnicotinic isn’t in the Cambridge Dictionary yet. You can help! Blockade of muscarinic acetylcholine receptors had a smaller effect than the partial blockade of nicotinic acetylcholine receptors. There are two main groups of receptors for the neurotransmitter acetylcholine, known as muscarinic and nicotinic receptors. Whole-cell currents activated at nicotinic acetylcholine receptors on ganglion cells isolated from goldfish retina. Nicotinic receptors are important in memory and learning. Nicotinic receptors exhibit variable rates of desensitization upon exposure to ligand, depending upon their subunit composition. Molecular cloning, functional proper ties, and distribution of rat brain a7, a nicotinic cation channel highly permeable to calcium. The effects of nicotine and epibatidine on dopamine release were antagonized by mecamylamine confirming the involvement of nicotinic receptors. On finding that the activation of nicotinic receptors seemed to depress visual responses, we proceeded to investigate the mechanism of this effect. Three subtypes of alpha-bungarotoxin-sensitive nicotinic acetylcholine receptors are expressed in chick retina. Identification of regions involved in the binding of alpha-bungarotoxin to the human alpha7 neuronal nicotinic acetylcholine receptor using synthetic peptides. Nicotinic acetylcholine receptor channels are influenced by the physical state of their membrane environment. Nicotinic acetylcholine receptors containing a7 subunits are required for reliable synaptic transmission in situ. Reticular thalamic nucleus dysfunction, in turn, may be caused by nicotinic receptor abnormalities or dopaminergic hyperactivity. Relating neuronal nicotinic acetylcholine receptor subtypes defined by subunit composition and channel function. |
