This study reports the comparative molecular modeling, docking and dynamic simulations of human α9α10 nicotinic acetylcholine receptors complexed with acetylcholine, nicotine and α-conotoxin RgIA, using as templates the ...

The carotid bodies (CBs) are chemosensory organs that respond to hypoxemia with transmitter neurosecretion, leading to a respiratory reflex response. It has been proposed that acetylcholine is a key regulator of transmitter ...

The activity of tricyclic antidepressants (TCAs) at α7 and α9α10 nicotinic acetylcholine receptors (AChRs) as well as at hippocampal α7-containing (i.e., α7*) AChRs is determined by using Ca 2+ influx and electrophysiological ...

The α9 and α10 nicotinic acetylcholine receptor (nAChR) subunits assemble to form the α9α10 nAChR subtype. This receptor is believed to mediate cholinergic synaptic transmission between efferent olivocochlear fibers and ...

Nicotinic acetylcholine receptors (nAChRs) are a subfamily of pentameric ligand-gated ion channels with members identified in most eumetazoan clades. In vertebrates, they are divided into three subgroups, according to their ...

Aims: Even though the presence of α7 nicotinic receptor (nAChR) in lymphocytes has been demonstrated, its functional role still remains elusive. The aim of our study was to characterize α7 nAChRs in human lymphocytes upon ...

In the present work, we characterized the effects of serotonin type 3 receptor ligands on recombinant and native α9α10-containing nicotinic acetylcholine receptors (nAChRs). Our results indicate that the recombinant α9α10 ...

Abstract: (1) Background: The lung cholinergic pathway is important for controlling pulmonary inflammation in acute lung injury, a condition that is characterized by a sudden onset and intense inflammation. This study ...

Effects of cytisine (cy), 3-bromocytisine (3-Br-cy), 5-bromocytisine (5-Br-cy) and 3,5-dibromocytisine (3,5-diBr-cy) on human (h) α7-, α4β2- and α4β4 nicotinic acetylcholine (nACh) receptors, expressed in Xenopus oocytes ...
