Dualsteric and dual‐acting modulation of muscarinic receptors by antagonist KH‐5
Abstract Background and purpose Muscarinic acetylcholine receptors are key therapeutic targets, and ligands engaging both orthosteric and allosteric sites may offer improved selectivity and efficacy. Here, we investigated whether the muscarinic antagonist KH‐5 acts as a dualsteric antagonist and defined its mode of interaction with muscarinic receptors.

Muscarinic agonists for schizophrenia: Bridging preclinical evidence and clinical enthusiasm
Abstract Antipsychotic drugs targeting dopamine receptors have been used to treat schizophrenia for decades, primarily alleviating positive symptoms such as hallucinations and delusions. However, they provide limited benefit for cognitive and negative symptoms—major contributors to poor outcomes—and are frequently associated with significant side ...

Is sleep affected after microgravity and hypergravity exposure? A pilot study
Summary Sleep is known to be affected in space travel and in residents of the international space station. But little is known about the direct effects of gravity changes on sleep, if other factors, such as sleep conditions, are kept constant. Here, as a first exploration, we investigated sleep before and after exposure to short bouts of microgravity ...

Cholinergic control of visual categorisation in macaques
Acetylcholine (ACh) is a neurotransmitter acting via muscarinic and nicotinic receptors that is implicated in several cognitive functions and impairments, such as Alzheimer’s disease. It is believed to especially affect the acquisition of new information,
