Stabilized Ion Selectivity Corrects Activation Drift in Kalium Channelrhodopsins

Advanced 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 ...

Cholinergic neurons in the dorsomedial hypothalamus regulate food intake

Molecular Metabolism, 2017
Objective: Central cholinergic neural circuits play a role in the regulation of feeding behavior. The dorsomedial hypothalamus (DMH) is considered the appetite-stimulating center and contains cholinergic neurons.

Thalamic inputs to dorsomedial striatum are involved in inhibitory control: evidence from the five-choice serial reaction time task in rats [PDF]

, 2017
Rationale Corticostriatal circuits are widely implicated in the top-down control of attention including inhibitory control and behavioural flexibility. However, recent neurophysiological evidence also suggests a role for thalamic inputs to striatum in

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

Advanced 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.

Young Human Cholinergic Neurons Respond to Physiological Regulators and Improve Cognitive Symptoms in an Animal Model of Alzheimer’s Disease

Frontiers in Cellular Neuroscience, 2017
The degeneration of cholinergic neurons of the nucleus basalis of Meynert (NBM) in the basal forebrain (BF) is associated to the cognitive decline of Alzheimer’s disease (AD) patients. To date no resolutive therapies exist. Cell-based replacement therapy

Unraveling the Morphological and Functional Maturation Mechanisms Underlying Human Neural Development Using iPSCs‐Derived Neuronal Model

Advanced Science, EarlyView.
Using human induced pluripotent stem cells (hiPSCs)‐derived neuronal model, Tian and colleagues reveal that voltage‐gated calcium channels Cav1.2 and Cav1.3, and their mediated calcium ion influx, are essential for early morphogenesis of human neuronal development, while ECEL1 underlies human neuronal functional developmental maturation through CALM3 ...

Cooperative Glutamatergic and Cholinergic Mechanisms Generate Short-Term Modifications of Synaptic Effectiveness in Prepositus Hypoglossi Neurons [PDF]

, 2005
To maintain horizontal eye position on a visual target after a saccade, extraocular motoneurons need a persistent (tonic) neural activity, called "eye-position signal," generated by prepositus hypoglossi (PH) neurons.
