Abnormal response to chronic social defeat stress and fear extinction in a mouse model of Lynx2-based cholinergic dysregulation

Frontiers in Neuroscience
Nicotinic receptor signaling is influential in modulating appropriate responses to salient stimuli within a complex environment. The cholinergic neurotransmitter system drives attention to salient stimuli such as stressors, and aids in orchestrating the ...

Developmental sex differences in nicotinic currents of prefrontal layer VI neurons in mice and rats.

PLoS ONE, 2010
BackgroundThere is a large sex difference in the prevalence of attention deficit disorder; yet, relatively little is known about sex differences in the development of prefrontal attention circuitry.

Distribution of Nicotinic Receptors in the Human Brain: Quantitative Autoradiography Using 3H-Nicotine

, 1988
Several studies showed clearly that the mammalian central nervous system possess nicotinic receptors. Recently, using membrane receptor binding studies the regional distribution of 3H-nicotine and/or H-acetylcholine binding sites in the human brain has ...

Physicochemical, Functional, and Health‐Promoting Properties of Processed Nettle (Urtica Dioica) Leaves: A Review

Future Postharvest and Food, EarlyView.
Stinging nettle (Urtica dioica L.) leaves are a nutrient‐dense source of proteins, dietary fiber, chlorophylls, carotenoids, and phenolic compounds. Processing technologies enable the production of powders and extracts for incorporation into bakery, beverage, dairy, and nutraceutical products; however, challenges remain regarding sensory quality ...

Philanthotoxin analogues that selectively inhibit ganglionic nicotinic acetylcholine receptors with exceptional potency [PDF]

, 2019
Philanthotoxin-433 (PhTX-433) is an active component of the venom from the Egyptian digger wasp, Philanthus triangulum. PhTX-433 non-selectively inhibits several excitatory ligand-gated ion channels, and we recently showed that its synthetic analogue ...

Progress in the Role of Mast Cells and Biomolecular Signals in the Mechanism of Postoperative Ileus: From Cellular Activation to Exploration of the Brain–Gut Axis

Gut Medicine, EarlyView.
ABSTRACT Postoperative ileus (POI) is a frequent complication after surgical procedures, predominantly manifesting as aberrant gastrointestinal motility, which markedly extends the duration of postoperative recovery for patients. The clinical duration of POI is typically modulated by intricate inflammatory cascades, with mast cells assuming a critical ...

Engineered 3D cultured human nasal mucosa mesenchymal stem cell derived sEVs for targeted brain‐derived neurotrophic factor delivery to enhance neurogenesis and attenuate brain damage

Interdisciplinary Medicine, EarlyView.
This study successfully developed and evaluated BDNF@RVG‐sEVs, a novel brain‐targeted nanomedicine based on hnmMSC‐derived sEVs, designed to overcome the BBB and enhance neurorestoration. By integrating RVG for enhanced brain targeting and encapsulating BDNF for potent neurorepair, our system address the key limitations of the conventional sEVs and ...

Generation of nanobodies acting as silent and positive allosteric modulators of the α7 nicotinic acetylcholine receptor

, 2023
International audienceThe α7 nicotinic acetylcholine receptor (nAChR), a potential drug target for treating cognitive disorders, mediates communication between neuronal and non- neuronal cells. Although many competitive antagonists, agonists, and partial-

Diaphragm Ultrasonography Reveals Progressive Changes in Diaphragmatic Function, Morphology, and Muscle Trophism During Invasive Mechanical Ventilation in Children

Journal of Clinical Ultrasound, EarlyView.
Diaphragm ultrasonography detected progressive structural and functional deterioration in mechanically ventilated children. Prolonged invasive mechanical ventilation and neuromuscular blocking agent use were associated with ventilator‐induced diaphragmatic dysfunction, highlighting ultrasound as a valuable bedside tool to support individualized ...
