Cholinergic regulation of mood: from basic and clinical studies to emerging therapeutics. [PDF]

, 2019
Mood disorders are highly prevalent and are the leading cause of disability worldwide. The neurobiological mechanisms underlying depression remain poorly understood, although theories regarding dysfunction within various neurotransmitter systems have ...

Cholesterol modulates acetylcholine receptor diffusion by tuning confinement sojourns and nanocluster stability [PDF]

, 2018
Translational motion of neurotransmitter receptors is key for determining receptor number at the synapse and hence, synaptic efficacy. We combine live-cell STORM superresolution microscopy of nicotinic acetylcholine receptor (nAChR) with single-particle ...

Evolution of vertebrate nicotinic acetylcholine receptors

BMC Evolutionary Biology, 2019
Background Many physiological processes are influenced by nicotinic acetylcholine receptors (nAChR), ranging from neuromuscular and parasympathetic signaling to modulation of the reward system and long-term memory.

Single‐Cell Transcriptome Atlas Reveals the Underlying Mechanism of Kynurenic Acid in the Regulation of Tumor Immune Microenvironment in Glioblastoma

Advanced Science, EarlyView.
KYNA regulates the tumor immune microenvironment in glioblastoma. KYNA reprograms the balance between T cell exhaustion and activation to suppress glioblastoma progression through inhibiting exhaustion‐associated markers (such as PD‐1, LAG3, and TOX) and enhancing immune activation and cytotoxicity markers including granzymes GZMA and GZMB.

A photoisomerizable muscarinic antagonist. Studies of binding and of conductance relaxations in frog heart [PDF]

, 1982
These experiments employ the photoisomerizable compound, 3,3'-bis- [alpha-(trimethylammonium)methyl]azobenzene (Bis-Q), to study the response to muscarinic agents in frog myocardium. In homogenates from the heart, trans-Bis-Q blocks the binding of [3H]-N-

Unique nicotinic responses are present in distinct subtypes of mouse medial prefrontal layer V pyramidal neurons

Scientific Reports
The neurotransmitter acetylcholine supports goal-directed cognitive functions via activation of its nicotinic and muscarinic classes of receptors within the prefrontal cortex.

Smoking‐Induced STC2+ Tumor Cells Drive Tumor‐Vascular Crosstalk in Laryngeal Squamous Cell Carcinoma via Spatial and Single‐Cell Transcriptomics

Advanced Science, EarlyView.
This study identifies a smoking‐induced mechanism in LSCC whereby nicotine activates the CHRNA5–JAK2/STAT3 axis to drive STC2 transcription. STC2 upregulates TGFBI, which interacts with endothelial ITGA5 to regulate vascular permeability and promote metastasis.

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.

Differential Expression and Function of Nicotinic Acetylcholine Receptors in Subdivisions of Medial Habenula

Journal of Neuroscience, 2014
Neuronal nAChRs in the medial habenula (MHb) to the interpeduncular nucleus (IPN) pathway are key mediators of nicotine's aversive properties. In this paper, we report new details regarding nAChR anatomical localization and function in MHb and IPN. A new

Overview of Encapsulated Lysine and Methionine and Their Impacts on Transition Cow Performance and Health

Animal Research and One Health, EarlyView.
The transition period in dairy cows, spanning 3 weeks before and after calving, is a critical phase characterized by increased nutrient demands, reduced dry matter intake (DMI), and elevated risk of metabolic disorders such as negative nutrient balance (NNB), lipolysis, proteolysis, and oxidative stress.
