Silent agonists for α7 nicotinic acetylcholine receptors

Pharmacological Research, 2023
We discuss models for the activation and desensitization of α7 nicotinic acetylcholine receptors (nAChRs) and the effects of efficacious type II positive allosteric modulators (PAMs) that destabilize α7 desensitized states.

Severe drug-induced repetitive behaviors and striatal overexpression of VAChT in ChAT-ChR2-EYFP BAC transgenic mice

Frontiers in Neural Circuits, 2014
In drug users, drug-related cues alone can induce dopamine release in the dorsal striatum. Instructive cues activate inputs to the striatum from both dopaminergic and cholinergic neurons, which are thought to work together to support motor learning and ...

Cannabinoid CB2 receptor‐mediated analgesia: mechanism‐based insights and therapeutic potential

British Journal of Pharmacology, EarlyView.
Agonists of the cannabinoid 2 (CB2) receptor have shown promise for the treatment of pain in a variety of animal models. However, despite current preclinical evidence supporting the use of CB2 agonists for pain, successful translation of findings from preclinical models to human patients is lacking.

Nicotinic Receptor Activity Alters Synaptic Plasticity

The Scientific World Journal, 2001
Studies using specific agonists, antagonists, and lesions have shown that nicotinic cholinergic systems participate in attention, learning, and memory[1,2].

Cholinergic modulation of the medial prefrontal cortex: the role of nicotinic receptors in attention and regulation of neuronal activity

Frontiers in Neural Circuits, 2014
Acetylcholine release in the medial prefrontal cortex is (mPFC) crucial for normal cognitive performance. Despite the fact that many have studied how acetylcholine affects neuronal processing in the mPFC and thereby influences attention behavior, there ...

Structure–activity relationship of the allosteric effects of ivermectin at human P2X4 and GABAA receptors

British Journal of Pharmacology, EarlyView.
Abstract Background and purpose Positive allosteric modulation of the P2X4 receptor is a potential route to providing cardiovascular benefit through enhancing flow‐dependent arterial vasodilation and providing cardioprotection. However, ligands that selectively enhance P2X4 activity are absent.

The Application of Polymeric Nanoparticles as Drug Delivery Carriers to Cells in Neurodegenerative Diseases

Cell Proliferation, EarlyView.
Polymeric nanoparticles represent promising drug (gene) delivery carriers to the brain due to their unique advantages to facilitate the penetration of blood–brain barrier and endocytosis of neuronal cells in neurodegenerative diseases. ABSTRACT In spite of great advances in modern medicine, there are a few effective strategies for the treatment of ...

Cholinergic receptor alterations in the cerebral cortex of spinal cord injured rat

Biochemistry and Biophysics Reports, 2017
Many areas of the cerebral cortex process sensory information or coordinate motor output necessary for control of movement. Disturbances in cortical cholinergic system can affect locomotor coordination.

KYNA Ameliorates Hepatic Ischemia–Reperfusion Injury by Activating the Hippo Signalling Pathway via FTO‐Dependent m6A Demethylation of LATS1

Cell Proliferation, EarlyView.
Our study elucidates the cellular and molecular mechanisms underlying KYNA's protective effects against HIRI. It emphasises that KYNA modulates the methylation status of the Hippo signalling pathway through the activation of AHR, thereby mitigating damage by promoting LATS1 degradation and facilitating the nuclear translocation of YAP. ABSTRACT Hepatic

Evaluation of the cholinomimetic actions of trimethylsulfonium, a compound present in the midgut gland of the sea hare Aplysia brasiliana (Gastropoda, Opisthobranchia)

Brazilian Journal of Medical and Biological Research, 2002
Trimethylsulfonium, a compound present in the midgut gland of the sea hare Aplysia brasiliana, negatively modulates vagal response, indicating a probable ability to inhibit cholinergic responses.
