The nicotinic acetylcholine receptor (nAChR) is a major target of autoantibodies in myasthenia gravis (MG), an autoimmune disease that causes neuromuscular transmission dysfunction. Despite decades of research, the molecular mechanisms underlying MG have not been fully elucidated. Here, we present the crystal structure of the nAChR α1 subunit bound by the Fab fragment of mAb35, a reference mono...
The avian hippocampal formation (HF) and mammalian hippocampus share a similar functional role in spatial cognition, but the underlying neuronal mechanisms allowing the functional similarity are incompletely understood. To understand better the organization of the avian HF and its transmitter receptors, we analyzed binding site densities for glutamatergic AMPA, NMDA, and kainate receptors; GABA...
Propofol as an agonist of GABAA receptor has a rewarding and discriminative stimulus effect. However, which subtype of the GABAA receptor is involved in the discriminative stimulus effects of propofol is still not clear. We observed the effects of an agonist or an antagonist of the subtype-selective GABAA receptor on discriminative stimulus effects of propofol. Male Sprague-Dawley rats were tra...
In addition to both the α1 adrenergic receptor and N-methyl-D-aspartate (NMDA) receptor antagonists, ifenprodil binds to the sigma receptor subtypes 1 and 2. In this study, we examined the effects of ifenprodil on nerve growth factor (NGF)-induced neurite outgrowth in PC12 cells. Ifenprodil significantly potentiated NGF-induced neurite outgrowth, in a concentration-dependent manner. In contrast...
BACKGROUND Several drugs are approved for the treatment of lower urinary tract symptoms (LUTS) in men, but these are mostly used by clinicians as monotherapies. The combination of different compounds, each of which targets a different aspect of LUTS, seems appealing. However, only few clinical trials have evaluated the effects of combination therapies. OBJECTIVE This systematic review analyze...
GABAergic input to Gonadotropin-releasing hormone (GnRH) neurons is necessary to initiate the onset of puberty and its action mainly depends on GABAA receptor of which the subunit composition, properties and consequently function varies during this period. Nourishing “Yin”-Removing “Fire” Chinese herb mixture, a Chinese herb-based formulation, has been proved that it may retard the initiation o...
