Up-regulation of nicotinic acetylcholine receptors in menthol cigarette smokers.

International Journal of Neuropsychopharmacology, 2013
One-third of smokers primarily use menthol cigarettes and usage of these cigarettes leads to elevated serum nicotine levels and more difficulty quitting in standard treatment programmes.

Physics of Protein Aggregation in Normal and Accelerated Brain Aging

BioEssays, EarlyView.
Soluble monomeric proteins precipitate via nucleation into insoluble amyloids in response to age‐related exposures (e.g., microbes, nanoparticles). Persistent soluble‐to‐insoluble phase transition depletes the functional proteins. In normal aging, replacement matches loss; in accelerated aging, it does not.

Identification of critical residues in loop E in the 5-HT(3AS)R binding site [PDF]

, 2002
BACKGROUND: The serotonin type 3 receptor (5-HT(3)R) is a member of a superfamily of ligand gated ion channels. All members of this family share a large degree of sequence homology and presumably significant structural similarity.

Deciphering the skeletal interoceptive circuitry to control bone homeostasis

BMEMat, EarlyView.
This review introduces the skeletal interoceptive circuitry, covering the ascending signals from bone tissues to the brain (sensors), the central neural circuits that integrate this information and dispatch commands (CPU), and the descending pathways that regulate bone homeostasis (effectors).

Chronic Nicotine Selectively Enhances α4β2* Nicotinic Acetylcholine Receptors in the Nigrostriatal Dopamine Pathway [PDF]

, 2009
These electrophysiological experiments, in slices and intact animals, study the effects of in vivo chronic exposure to nicotine on functional α4β2* nAChRs in the nigrostriatal dopaminergic (DA) pathway.

NSAIDS AS MODULATORS OF CATION CHANNELS: FENAMATES REPURPOSING IN CHANNELOPATHIES

ChemMedChem, Accepted Article.
Cationic ion channels are transmembrane proteins that regulate the flux of cations (potassium, sodium, and calcium) across cell membrane, playing a pivotal role in many cellular functions. Disruptions of their activity can lead to the so‐called genetic or acquired channelopathies, a heterogeneous group of diseases that affect multiple human systems ...

The Role of Nicotinic Receptors on Ca²⁺ Signaling in Bovine Chromaffin Cells

Current Issues in Molecular Biology
Chromaffin cells have been used as a physiological model to understand neurosecretion in mammals for many years. Nicotinic receptors located in the cells’ membrane are stimulated by acetylcholine, and they participate in the exocytosis of chromaffin ...

Dendritic spine density of prefrontal layer 6 pyramidal neurons in relation to apical dendrite sculpting by nicotinic acetylcholine receptors

Frontiers in Cellular Neuroscience, 2015
Prefrontal layer 6 (L6) pyramidal neurons play an important role in the adult control of attention, facilitated by their strong activation by nicotinic acetylcholine receptors.

Altered muscarinic and nicotinic receptor densities in cortical and subcortical brain regions in Parkinson's disease [PDF]

, 1993
Muscarinic and nicotinic cholinergic receptors and choline acetyltransferase activity were studied in postmortem brain tissue from patients with histopathologically confirmed Parkinson's disease and matched control subjects.

Precision therapies for genetic epilepsies in 2025: Promises and pitfalls

Epilepsia Open, EarlyView.
Abstract By targeting the underlying etiology, precision therapies offer an exciting paradigm shift to improve the stagnant outcomes of drug‐resistant epilepsies, including developmental and epileptic encephalopathies. Unlike conventional antiseizure medications (ASMs) which only treat the symptoms (seizures) but have no effect on the underlying ...
