CARD9 Conveys Pancreatic Islet Sympathetic Nervous β2 Signals to Reshape Macrophage Creatine Metabolism in Type 1 Diabetes

Advanced Science, EarlyView.
This study identifies CARD9 as a key mediator linking sympathetic β2‐adrenergic receptor signaling to macrophage creatine metabolism, inflammatory polarization, and neuronal integrity. Loss of β2‐AR‐PKA‐CREB1‐CARD9 signaling in macrophages reduces creatine uptake, promotes pro‐inflammatory macrophage activation, and drives sympathetic axon ferroptosis.

Reliability and stability of tactile perception in the whisker somatosensory system

Frontiers in Neuroscience
Rodents rely on their whiskers as vital sensory tools for tactile perception, enabling them to distinguish textures and shapes. Ensuring the reliability and constancy of tactile perception under varying stimulus conditions remains a fascinating and ...

Articulating: the neural mechanisms of speech production [PDF]

, 2019
Speech production is a highly complex sensorimotor task involving tightly coordinated processing across large expanses of the cerebral cortex. Historically, the study of the neural underpinnings of speech suffered from the lack of an animal model.

Mitochondrial CISD1 Modulates Microglial Metabolic Reprogramming to Drive Stress Susceptibility in Mice

Advanced Science, EarlyView.
CDGSH iron sulfur domain 1 (CISD1) mitigates oxidative stress by promoting NADH oxidation and Coenzyme Q (CoQ) reduction. Under chronic stress, elevated CISD1 expression in microglia enhances NAD⁺ production, thereby increasing GAPDH activity and glycolytic flux, while reducing ATP synthesis by inhibiting proton transfer from mitochondrial complexes I ...

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 ...

Robotic Materials With Bioinspired Microstructures for High Sensitivity and Fast Actuation

Advanced Science, EarlyView.
In the review paper, design rationale and approaches for bioinspired sensors and actuators in robotics applications are presented. These bioinspired microstructure strategies implemented in both can improve the performance in several ways. Also, recent ideas and innovations that embed robotic materials with logic and computation with it are part of the

Altered Forebrain Functional Connectivity and Neurotransmission in a Kinase-Inactive Mouse Model of Autism

Molecular Imaging, 2019
MET , the gene encoding the tyrosine kinase receptor for hepatocyte growth factor, is a susceptibility gene for autism spectrum disorder (ASD). Genetically altered mice with a kinase-inactive Met offer a potential model for understanding neural circuit ...
