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.

Uniquely human CHRFAM7A gene increases the hematopoietic stem cell reservoir in mice and amplifies their inflammatory response. [PDF]

open access: yes, 2019
A subset of genes in the human genome are uniquely human and not found in other species. One example is CHRFAM7A, a dominant-negative inhibitor of the antiinflammatory α7 nicotinic acetylcholine receptor (α7nAChR/CHRNA7) that is also a neurotransmitter ...

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 ...

Management of Anxiety in Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Anxiety is a common, distressing, hard‐to‐diagnose and hard‐to‐treat symptom in Parkinson's disease. No formal guidelines exist to assist management. Objective We provide a pragmatic guide to detecting and managing anxiety in Parkinson's disease.

PPAR-alpha agonists as novel antiepileptic drugs: preclinical findings. [PDF]

open access: yesPLoS ONE, 2013
Nicotinic acetylcholine receptors (nAChRs) are involved in seizure mechanisms. Hence, nocturnal frontal lobe epilepsy was the first idiopathic epilepsy linked with specific mutations in α4 or β2 nAChR subunit genes.

Combined nutritional stress and a new systemic pesticide (flupyradifurone, Sivanto®) reduce bee survival, food consumption, flight success, and thermoregulation. [PDF]

open access: yes, 2019
Flupyradifurone (FPF, Sivanto®) is a new butenolide insecticide that, like the neonicotinoids, is a systemic nicotinic acetylcholine receptor (nAChR) agonist.

Activation of endplate nicotinic acetylcholine receptors by agonists [PDF]

open access: yesBiochemical Pharmacology, 2015
The interaction of a small molecule made in one cell with a large receptor made in another is the signature event of cell signaling. Understanding the structure and energy changes associated with agonist activation is important for engineering drugs, receptors and synapses.

The Supportive Effect of Acarbose to Orlistat in Weight Management—A Randomized, Double‐Blind, Multiarm Phase 2 Trial

open access: yesObesity, EarlyView.
ABSTRACT Objective This study aimed to evaluate the added effect of acarbose to orlistat on relative weight loss in the novel antiobesity medication EMP16. Methods In this 6‐month double‐blind trial, 240 individuals with obesity or overweight and comorbidities were randomized equally into three groups: (1) EMP16 (120 mg modified release orlistat/40 mg ...

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 ...

Proteolytic stabilization of a spider venom peptide results in an orally active bioinsecticide

open access: yesPest Management Science, EarlyView.
Selective editing out of an insect gut protease cleavage site renders a spider‐derived insecticidal peptide active by ingestion by insect pests. Abstract BACKGROUND The toxin peptide U1‐AGTX‐Ta1b from the Hobo spider, Eratigena agrestis (Walckenaer, 1802), was studied to determine its potential to serve as a bioinsecticide.
