Involvement of Nitric Oxide in Depolarization-Induced Suppression of Inhibition in Hippocampal Pyramidal Cells during Activation of Cholinergic Receptors

open access: yesJournal of Neuroscience, 2007
Several types of neurons are able to regulate their synaptic inputs via releasing retrograde signal molecules, such as endocannabinoids or nitric oxide (NO).

Neural Response Reliability as a Marker of the Transition of Neural Codes along Auditory Pathways

open access: yesAdvanced Science, EarlyView.
Decoding sound from neural activity in mice reveals a striking shift in how the brain encodes sound: from precise but redundant timing codes in early auditory areas to efficient, synergistic rate‐based codes in the cortex. This transformation highlights a robust neural strategy for turning complex acoustic input into coherent perception across the ...

Identification of atropine-and P2X1 receptor antagonist-reistant, neurogenic contractions of the urinary bladder [PDF]

open access: yes, 2007
Acetylcholine and ATP are excitatory cotransmitters in parasympathetic nerves. We used P2X1 receptor antagonists to further characterize the purinergic component of neurotransmission in isolated detrusor muscle of guinea pig urinary bladder.

Stabilized Ion Selectivity Corrects Activation Drift in Kalium Channelrhodopsins

open access: yesAdvanced Science, EarlyView.
As newly emerged optogenetic tools, potassium channelrhodopsins (KCRs) can drift from inhibition to activation during illumination as K⁺ selectivity declines. It is shown that both the absolute K⁺/Na⁺ permeability ratio and its stability over time govern this drift, identify KCR1‐C29D as a reliably inhibitory variant, and outline design principles for ...

A Dopamine-Acetylcholine Cascade: Simulating Learned and Lesion-Induced Behavior of Striatal Cholinergic Interneurons [PDF]

open access: yes, 2007
The "teaching signal" that modulates reinforcement learning at cortico-striatal synapses may be a sequence composed of an adaptively scaled DA burst, a brief ACh burst, and a scaled ACh pause.

A Single‐Molecule Pleuripotent Scaffold for Combinational Therapy of Alzheimer's Disease via Intranasal Administration

open access: yesAdvanced Science, EarlyView.
Herein, guanidinium‐modified calix[5]arene (GC5AY) is developed featuring small size, positive charge, and desirable amphiphilicity, that can efficiently traverse the nasal mucosal barrier for brain drug delivery. Additionally, possessing inherent therapeutic functions, GC5AY can thus serve as a single‐molecule pleuripotent scaffold for multi‐target ...

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.

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 ...

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
