Minimal Structural Changes Determine Full and Partial Nicotinic Receptor Agonist Activity for Nicotine Analogues

open access: yesMolecules, 2019
Neuronal α4β2 nicotinic acetylcholine receptors (nAChRs) are ligand-gated ion channels (LGIC) that have been implicated in nicotine addiction, reward, cognition, pain disorders, anxiety, and depression.

Two Amino Acid Residues Contribute to a Cation-π Binding Interaction in the Binding Site of an Insect GABA Receptor [PDF]

open access: yes, 2011
Cys-loop receptor binding sites characteristically possess an "aromatic box," where several aromatic amino acid residues surround the bound ligand. A cation-π interaction between one of these residues and the natural agonist is common, although the ...

Neurodevelopmental burden in young adults undergoing opioid substitution therapy: The role of inattentive and hyperactive/impulsive symptoms

open access: yesThe American Journal on Addictions, EarlyView.
Abstract Background and Objectives Attention‐deficit/hyperactivity disorder (ADHD) is recognized as a condition that can persist into adulthood, often with psychiatric comorbidities that worsen the overall prognosis. ADHD has been associated with substance use disorders (SUDs), especially through symptoms like hyperactivity and impulsivity, while the ...

Acetylcholine From Solitary Chemosensory Cell, Not Neuron, Regulates Basal Cell Fate Driving Eosinophilic Chronic Rhinosinusitis With Nasal Polyps

open access: yesAllergy, EarlyView.
This study identifies that Ach levels are elevated in eCRSwNP and primarily released from SCCs rather than neurons. Ach induces epithelial remodeling in eCRSwNP by binding to M1R/M3R and activating YAP signaling in basal cells, driving basal cell hyperplasia and abnormal differentiation. Blocking M1R/M3R with TB inhibits eCRSwNP progression.

Arachidonic Acid as a Possible Negative Feedback Inhibitor of Nicotinic Acetylcholine Receptors on Neurons [PDF]

open access: yes, 1995
Neuronal acetylcholine receptors, being highly permeable to calcium, are likely to regulate calcium-dependent events in neurons. Arachidonic acid is a membrane-permeant second messenger that can be released from membrane phospholipids by phospholipases ...

Anti‐inflammatory effects of physical stimuli: The central role of networks in shaping the future of pharmacological research

open access: yesBritish Journal of Pharmacology, EarlyView.
Addressing complexity in the study of life sciences through Systems Biology and Systems Medicine has been transformative, making Systems Pharmacology the next logical step. In this review, we focus on physical stimuli, whose potential in pharmacology has been neglected, despite demonstrated therapeutic properties.

Nicotine Inhibits Clostridium difficile Toxin A-Induced Colitis but Not Ileitis in Rats

open access: yesInternational Journal of Inflammation, 2016
Nicotine is protective in ulcerative colitis but not Crohn’s disease of the small intestine, but little is known about the effects of nicotine on Clostridium difficile toxin A-induced enteritis.

Probing for and Quantifying Agonist Hydrogen Bonds in α6β2 Nicotinic Acetylcholine Receptors [PDF]

open access: yes, 2017
Designing subtype-selective agonists for neuronal nicotinic acetylcholine receptors (nACh¬R) is a challenging and significant goal aided by intricate knowledge of each subtype’s binding patterns.

Psychedelics as pharmacotherapeutics for substance use disorders: A scoping review on clinical trials and perspectives on underlying neurobiology

open access: yesBritish Journal of Pharmacology, EarlyView.
Theorized mechanism of dopamine homeostasis restoration in the nucleus accumbens core induced by a psychedelic intervention. Abstract Psychedelics have garnered great attention in recent years as treatments for major depressive disorder (MDD) and treatment‐resistant depression because of their ability to alter consciousness and afflicted cognitive ...
