Prefrontal β2 Subunit-Containing and α7 Nicotinic Acetylcholine Receptors Differentially Control Glutamatergic and Cholinergic Signaling

Journal of Neuroscience, 2010
One-second-long increases in prefrontal cholinergic activity (“transients”) were demonstrated previously to be necessary for the incorporation of cues into ongoing cognitive processes (“cue detection”).

Adrenergic and Cholinergic Receptors of Cerebral Microvessels [PDF]

Journal of Cerebral Blood Flow & Metabolism, 1981
The presence of α- and β-adrenergic and muscarinic cholinergic receptors in cerebral microvessels of the rat and pig was assessed by ligand binding techniques. The results demonstrate the presence of specific binding to α2- and β-adrenergic receptors but no appreciable specific binding to α1-adrenergic or muscarinic cholinergic receptors. β-Adrenergic

Increased accuracy of ligand sensing by receptor diffusion on cell surface [PDF]

Physical Review E 82, 041902 (2010), 2010
The physical limit with which a cell senses external ligand concentration corresponds to the perfect absorber, where all ligand particles are absorbed and overcounting of same ligand particles does not occur. Here we analyze how the lateral diffusion of receptors on the cell membrane affects the accuracy of sensing ligand concentration.

Cholinergic Modulation of Locomotion and Striatal Dopamine Release Is Mediated by α6α4* Nicotinic Acetylcholine Receptors

Journal of Neuroscience, 2010
Dopamine (DA) release in striatum is governed by firing rates of midbrain DA neurons, striatal cholinergic tone, and nicotinic ACh receptors (nAChRs) on DA presynaptic terminals. DA neurons selectively express α6* nAChRs, which show high ACh and nicotine

Young Human Cholinergic Neurons Respond to Physiological Regulators and Improve Cognitive Symptoms in an Animal Model of Alzheimer’s Disease

Frontiers in Cellular Neuroscience, 2017
The degeneration of cholinergic neurons of the nucleus basalis of Meynert (NBM) in the basal forebrain (BF) is associated to the cognitive decline of Alzheimer’s disease (AD) patients. To date no resolutive therapies exist. Cell-based replacement therapy

Treatment of cholinergic‐induced status epilepticus with polytherapy targeting GABA and glutamate receptors

Epilepsia Open, 2023
Despite new antiseizure medications, the development of cholinergic‐induced refractory status epilepticus (RSE) continues to be a therapeutic challenge as pharmacoresistance to benzodiazepines and other antiseizure medications quickly develops.

The impact of high density receptor clusters on VEGF signaling [PDF]

EPTCS 125, 2013, pp. 37-52, 2013
Vascular endothelial growth factor (VEGF) signaling is involved in the process of blood vessel development and maintenance. Signaling is initiated by binding of the bivalent VEGF ligand to the membrane-bound receptors (VEGFR), which in turn stimulates receptor dimerization.

Cortical Control of Striatal Dopamine Transmission via Striatal Cholinergic Interneurons

Cerebral Cortex, 2016
Corticostriatal regulation of striatal dopamine (DA) transmission has long been postulated, but ionotropic glutamate receptors have not been localized directly to DA axons.
