Smoking‐Induced STC2+ Tumor Cells Drive Tumor‐Vascular Crosstalk in Laryngeal Squamous Cell Carcinoma via Spatial and Single‐Cell Transcriptomics

open access: yesAdvanced Science, EarlyView.
This study identifies a smoking‐induced mechanism in LSCC whereby nicotine activates the CHRNA5–JAK2/STAT3 axis to drive STC2 transcription. STC2 upregulates TGFBI, which interacts with endothelial ITGA5 to regulate vascular permeability and promote metastasis.

Effect of scopolamine-based amnesia on the number of astrocytes in the rat's hippocampus [PDF]

open access: yes, 2012
As neuron-astrocyte interactions play a crucial role in the adult brain, it is thought that astrocytes support learning and memory through specific mechanisms.

New approaches to treating chronic obstructive pulmonary disease with Colla corii asini

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Colla corii asini improves chronic obstructive pulmonary disease (COPD) treatment through anti‐inflammatory, antioxidant, immune‐modulatory, and lung‐nourishing effects, addressing current therapeutic challenges via multitarget mechanisms. Abstract Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death and disability ...

Simulating Effects of Learning and Lesions with a Model of Intrinsic and Synaptically Gated Responses of Striatal Cholinergic Interneurons [PDF]

open access: yes, 2006
The giant cholinergic interneurons of the striatum are tonically active neurons (TANs) that respond with characteristic pauses to novel events and to appetitive and aversive conditioned stimuli.

Toll-Like Receptor 4 Modulates Small Intestine Neuromuscular Function through Nitrergic and Purinergic Pathways [PDF]

open access: yes, 2017
Objective: Toll-like receptors (TLRs) play a pivotal role in the homeostatic microflora-host crosstalk. TLR4-mediated modulation of both motility and enteric neuronal survival has been reported mainly for colon with limited information on the role of ...

Cutting‐Edge Advancements in Physical Stimulation for Spiral Ganglion Neuron Protection and Regeneration

open access: yesAdvanced NanoBiomed Research, EarlyView.
Physical stimulation strategies have emerged as a therapeutic avenue for the regeneration of spiral ganglion neurons. This review explores diverse physical stimulation modalities—including topographical modulation, electrical stimulation, and photostimulation—each operating through distinct mechanisms to regulate SGN biological behavior. By elucidating

Nicotinic modulation of cortical circuits

open access: yesFrontiers in Neural Circuits, 2014
The ascending cholinergic neuromodulatory system sends projections throughout cortex and has been shown to play an important role in a number of cognitive functions including arousal, working memory, and attention. However, despite a wealth of behavioral

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

open access: yesThe 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.

Physiological functions of the cholinergic system in immune cells

open access: yesJournal of Pharmacological Sciences, 2017
T and B cells, macrophages and dendritic cells (DCs) all express most of the components necessary for a functional cholinergic system. This includes choline acetyltransferase (ChAT), muscarinic and nicotinic acetylcholine (ACh) receptors (mAChRs and ...

A continuum model for the dynamics of the phase transition from slow-wave sleep to REM sleep [PDF]

open access: yes, 2010
Previous studies have shown that activated cortical states (awake and rapid eye-movement (REM) sleep), are associated with increased cholinergic input into the cerebral cortex.
