Macrophage TNF-α mediates parathion-induced airway hyperreactivity in guinea pigs. [PDF]

open access: yes, 2013
Organophosphorus pesticides (OPs) are implicated in human asthma. We previously demonstrated that, at concentrations that do not inhibit acetylcholinesterase activity, the OP parathion causes airway hyperreactivity in guinea pigs as a result of ...

Delineating muscarinic receptor functions [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
Acetylcholine, as the first chemical molecule to be established as a neurotransmitter, has attracted enduring interest from researchers over several decades. However, deciphering all of the physiological manifestations associated with actions of this molecule has been difficult, and many mysteries of cholinergic neurotransmission still remain to be ...

Cortico‐Striatal‐Midbrain Circuit Dysregulation Underlying MK‐801 Induced Impulsivity and the Ameliorative Effects of SEP

open access: yesAdvanced Science, EarlyView.
Impulsivity is a symptom across multiple psychiatric disorders, yet its neural basis remains elusive. This study shows that the NMDAR antagonist MK‐801 elevates dopamine release and disrupts neuronal selectivity in the nucleus accumbens, leading to impulsive behavior.

Recovery of hippocampal functions and modulation of muscarinic response by electroacupuncture in young diabetic rats [PDF]

open access: yes, 2017
The muscarinic receptor response to acetylcholine regulates the hippocampal-related learning, memory, neural plasticity and the production and processing of the pro-nerve growth factor (proNGF) by hippocampal cells.

Subicular Astrocytes Govern Seizure‐Impaired Fear Memory

open access: yesAdvanced Science, EarlyView.
Astrocytes in dorsal subiculum act as a critical modulator of seizure‐associated cognitive dysfunction, operating through a Ca2+‐dependent adenosine‐linked astrocyte‐neuron signaling pathway that disrupts neuronal circuit homeostasis. This research highlights the potential of astrocyte‐targeted interventions as a therapeutic strategy, moving beyond the

Cholinergic partition cells and lamina X neurons induce a muscarinic-dependent short-term potentiation of commissural glutamatergic inputs in lumbar motoneurons.

open access: yesFrontiers in Neural Circuits, 2011
Acetylcholine and the activation of muscarinic receptors influence the activity of neural networks generating locomotor behaviour in the mammalian spinal cord.

The role of muscarinic receptors in the beneficial effects of adenosine against myocardial reperfusion injury in rats. [PDF]

open access: yesPLoS ONE, 2011
Adenosine, a catabolite of ATP, displays a wide variety of effects in the heart including regulation of cardiac response to myocardial ischemia and reperfusion injury.

Striatal cholinergic interneurons generate beta and gamma oscillations in the corticostriatal circuit and produce motor deficits [PDF]

open access: yes, 2016
Cortico-basal ganglia-thalamic (CBT) neural circuits are critical modulators of cognitive and motor function. When compromised, these circuits contribute to neurological and psychiatric disorders, such as Parkinson's disease (PD).

Endothelium‐Independent Relaxation of Alkaloid Boldine in Isolated Aortas From Normotensive and Hypertensive Rats: Participation of Ca2+ Channels

open access: yesChemistry &Biodiversity, EarlyView.
Involvement of Ca2+ channels in boldine‐induced vascular relaxation. ABSTRACT The regulation of vascular tone plays a fundamental role in blood pressure homeostasis and still represents a significant challenge in clinical practice. Boldine, a naturally occurring alkaloid from Peumus boldus, has emerged as a compound of interest due to its therapeutic ...

An update on the efficacy and safety of aclidinium bromide in patients with COPD

open access: yesTherapeutic Advances in Respiratory Disease, 2011
Aclidinium is a potent and selective muscarinic antagonist, which interacts rapidly with muscarinic receptors and shows subnanomolar affinity for the five human muscarinic receptors (M 1 –M 5 ); its association rate for the M 3 receptor is similar to ...
