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.

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

, 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.

High-affinity binding of [3H]acetylcholine to muscarinic cholinergic receptors

Journal of Neuroscience, 1985
High-affinity binding of [3H]acetylcholine to muscarinic cholinergic sites in rat CNS and peripheral tissues was measured in the presence of cytisin, which occupies nicotinic cholinergic receptors.

Noradrenergic and cholinergic innervation of the normal human heart and changes associated with cardiomyopathy

The Anatomical Record, EarlyView.
Abstract Autonomic nerves are crucial in cardiac function and pathology. However, data on the distribution of cholinergic and noradrenergic nerves in normal and pathologic human hearts is lacking. Nonfailing donor hearts were pressure‐perfusion fixed, imaged, and dissected. Left ventricular cardiomyopathy samples were also obtained.

Opioid and Nitrergic Pathways Mediate Antinociception by Pectis elongata Kunth. Essential Oil

Chemistry &Biodiversity, EarlyView.
ABSTRACT In the present study, we aimed to evaluate the antinociceptive potential of the Pectis elongata essential oil (PeEO) and to understand its mechanism of action by identifying possible pain inhibition pathways. PeEO was analyzed using gas chromatography coupled with mass spectrometry.

State-Dependent and -Independent Effects of Dialyzing Excitatory Neuromodulator Receptor Antagonists into the Ventral Respiratory Column [PDF]

, 2017
Unilateral dialysis of the broad-spectrum muscarinic receptor antagonist atropine (50 mM) into the ventral respiratory column [(VRC) including the pre-Bötzinger complex region] of awake goats increased pulmonary ventilation (V̇i) and breathing frequency (

Associations Between Nicotine Metabolites and Serum Neurofilament Light Chain Levels in the General Population

Chronic Diseases and Translational Medicine, EarlyView.
ABSTRACT Background Nicotine has been associated with cognitive functions such as memory and attention, with serum neurofilament light chain (sNfL) as a biomarker for neurological diseases such as Alzheimer's disease (AD) and multiple sclerosis (MS).

Precision therapies for genetic epilepsies in 2025: Promises and pitfalls

Epilepsia Open, EarlyView.
Abstract By targeting the underlying etiology, precision therapies offer an exciting paradigm shift to improve the stagnant outcomes of drug‐resistant epilepsies, including developmental and epileptic encephalopathies. Unlike conventional antiseizure medications (ASMs) which only treat the symptoms (seizures) but have no effect on the underlying ...

Perturbed synaptic adhesion molecules signaling in neurodevelopmental disorders: The impact of metal neurotoxicity

Ibrain, EarlyView.
Synaptic adhesion molecules (SAM) are essential for the formation, maturation, function, plasticity, and assembly of synaptic connections, all critical for normal neurodevelopment. Excessive exposure to neurotoxic metals during development could disrupt the developing brain and potentially lead to neurodevelopmental disorders (NDDs).
