Diverging mechanisms of activation of chemokine receptors revealed by novel chemokine agonists
(Public Library of Science, 2011)
CXCL8/interleukin-8 is a pro-inflammatory chemokine that triggers pleiotropic responses, including inflammation, angiogenesis, wound healing and tumorigenesis. We engineered the first selective CXCR1 agonists on the basis ...
Number and Locations of Agonist Binding Sites Required to Activate Homomeric Cys-Loop Receptors
(Society for Neuroscience, 2009)
Ligand binding to CNS muscarinic receptor is transiently modified by convulsant 3-mercaptopropionic acid administration
(Springer/Plenum Publishers, 2000-06)
The administration of convulsant drugs has proven a powerful tool to study experimental epilepsy. We have already reported that the administration of convulsant 3-mercaptopropionic acid (mp) at 150 mg/kg enhances binding ...
Inhibitory mechanisms and binding site location for serotonin selective reuptake inhibitors on nicotinic acetylcholine receptors
(Pergamon-Elsevier Science Ltd, 2010-05)
Functional and structural approaches were used to examine the inhibitory mechanisms and binding site location for fluoxetine and paroxetine, two serotonin selective reuptake inhibitors, on nicotinic acetylcholine receptors ...
Localization of agonist and competitive antagonist binding sites on nicotinic acetylcholine receptors
(Pergamon-Elsevier Science Ltd, 2000-06-01)
Identification of all residues involved in the recognition and binding of cholinergic ligands (e.g. agonists, competitive antagonists, and noncompetitive agonists) is a primary objective to understand which structural ...
Bovine Lactoferrin Decreases Cholera-Toxin-Induced Intestinal Fluid Accumulation in Mice by Ganglioside Interaction
(Public Library of Science, 2013)
Secretory diarrhea caused by cholera toxin (CT) is initiated by binding of CT’s B subunit (CTB) to GM1-ganglioside on the surface of intestinal cells. Lactoferrin, a breast milk glycoprotein, has shown protective effect ...
Activation of Caenorhabditis elegans Levamisole-Sensitive and Mammalian Nicotinic Receptors by the Antiparasitic Bephenium
(American Society for Pharmacology and Experimental Therapeutics, 2018-11)
Nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels involved in neuromuscular transmission. In nematodes, muscle nAChRs are targets of antiparasitic drugs. Bephenium is an anthelmintic compound whose ...
Biological relevance of Hsp90-binding immunophilins in cancer development and treatment
(John Wiley & Sons Inc, 2016-02)
Immunophilins are a family of intracellular receptors for immunosuppressive drugs. Those immunophilins that are related to immunosuppression are the smallest proteins of the family, i.e., FKBP12 and CyPA, whereas the other ...
Fatty acid signaling mechanisms in neural cells: Fatty acid receptors
(Frontiers Media, 2019-04-24)
Fatty acids (FAs) are typically associated with structural and metabolic roles, as they can be stored as triglycerides, degraded by β-oxidation or used in phospholipids’ synthesis, the main components of biological membranes. ...
