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).

Forebrain Cholinergic Signaling Regulates Innate Immune Responses and Inflammation

Frontiers in Immunology, 2019
The brain regulates physiological functions integral to survival. However, the insight into brain neuronal regulation of peripheral immune function and the neuromediator systems and pathways involved remains limited. Here, utilizing selective genetic and

Ovariectomy reduces cholinergic modulation of excitatory synaptic transmission in the rat entorhinal cortex.

PLoS ONE, 2022
Estrogens are thought to contribute to cognitive function in part by promoting the function of basal forebrain cholinergic neurons that project to the hippocampus and cortical regions including the entorhinal cortex.

Interactions between the neuromodulatory systems and the amygdala: exploratory survey using the Allen Mouse Brain Atlas. [PDF]

, 2013
Neuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system.

Perinatal Exposure to the Neonicotinoid Thiacloprid Impacts Transcription of Neuroplasticity and Neuroendocrine Markers in Mice but Not in the Zebrafish Model

Journal of Applied Toxicology, EarlyView.
ABSTRACT Neonicotinoids are widely used insecticides in agriculture, aquaculture, pet care, and urban pest control. Initially developed to selectively target the insect cholinergic system, their extensive use has raised concerns about adverse effects on nontarget vertebrates.

FRET-based detection of M1 muscarinic acetylcholine receptor activation by orthosteric and allosteric agonists.

PLoS ONE, 2012
Background and objectiveMuscarinic acetylcholine receptors (mAChRs) are 7-transmembrane, G protein-coupled receptors that regulate a variety of physiological processes and represent potentially important targets for therapeutic intervention.

Cell-Type Specific Neuromodulation of Excitatory and Inhibitory Neurons via Muscarinic Acetylcholine Receptors in Layer 4 of Rat Barrel Cortex

Frontiers in Neural Circuits, 2022
The neuromodulator acetylcholine (ACh) plays an important role in arousal, attention, vigilance, learning and memory. ACh is released during different behavioural states and affects the brain microcircuit by regulating neuronal and synaptic properties ...

Functional Magnetic Resonance Imaging (fMRI) Signatures of Progression and Phenoconversion in Prodromal Synucleinopathies

Movement Disorders, EarlyView.
Abstract Background Isolated rapid eye movement (REM) sleep behavior disorder (iRBD) is a prodromal manifestation of synucleinopathies and provides a critical window to identify early markers of progression to Parkinson's disease (PD) and dementia with Lewy bodies (DLB).

Modulation of c-Jun NH2-Terminal (JNK) by Cholinergic Autoantibodies from Patients with Sjögren’s Syndrome [PDF]

, 2011
Background: We wanted to determine (via an immunopharmacological approach) whether the c-Jun NH2 terminal kinase (JNK) cascade is phosphorylated in the submandibular gland by carbachol and cholinergic autoantibodies (IgG) present in the sera of patients ...
