scHeteroNet: A Heterophily‐Aware Graph Neural Network for Accurate Cell Type Annotation and Novel Cell Detection

Advanced Science, EarlyView.
scHeteroNet) is a novel graph neural network model that explicitly addresses heterophily in single‐cell sequencing data enabling accurate cell type annotation and novel cell type discovery. By leveraging heterophily‐aware message passing and novelty propagation mechanisms, scHeteroNet achieves superior performance in both cell annotation and detection ...

The contribution of astrocytes and microglia to traumatic brain injury

British Journal of Pharmacology, 2016
Traumatic brain injury (TBI) represents a major cause of death and disability in developed countries. Brain injuries are highly heterogeneous and can also trigger other neurological complications, including epilepsy, depression and dementia.

Activating the Astrocytes of the Dorsal Raphe Nucleus via Its Neural Circuits With the Medial Prefrontal Cortex Improves Depression in Mice

Behavioural Neurology
Astrocytes are the primary cell type in the central nervous system, responsible for maintaining the stability of the brain’s internal environment and supporting neuronal functions.

Accumulation of Damaging Lipids in the Arf1‐Ablated Neurons Promotes Neurodegeneration through Releasing mtDNA and Activating Inflammatory Pathways in Microglia

Advanced Science, EarlyView.
Arf1 defects activate the AKT‐mTORC1‐SREBP1‐FASN pathway to increase lipid synthesis and disrupt ER‐mitochondrial‐lysosomal homeostasis in neurons. Impaired mitochondria secrete damaged mtDNA via mitochondria‐derived extracellular vesicles, which is phagocytosed by the microglia and activated inflammation signaling.

Layer-specific morphological and molecular differences in neocortical astrocytes and their dependence on neuronal layers

Nature Communications, 2018
Non-pial neocortical astrocytes have historically been thought to comprise largely a nondiverse population of protoplasmic astrocytes. Here we show that astrocytes of the mouse somatosensory cortex manifest layer-specific morphological and molecular ...

Ultrasound‐Assisted H2 Transmitter Enables Hydrogen‐Gene Therapy to Prevent Anesthesia/Surgery‐Induced Cognitive Impairment

Advanced Science, EarlyView.
Postoperative cognitive dysfunction (POCD) remains a challenge with no effective treatments. This study introduces a novel hydrogen‐gene therapy strategy, combining focused ultrasound and siRNA delivery via hydrogen emitters, to repair neuroinflammation in a precise and controlled manner.

Quick Access to Human Astrocytic Software that Drives Neuronal Hardware

Stem Cell Reports, 2018
Astrocytes have important functions in the brain and their deregulation may cause disease. Current ways to derive astrocytes from pluripotent stem cells are labor, time, and resource intensive, but in this issue of Stem Cell Reports, Li et al.

Characterizing Learning in Spiking Neural Networks with Astrocyte-Like Units [PDF]

arXiv
Traditional artificial neural networks take inspiration from biological networks, using layers of neuron-like nodes to pass information for processing. More realistic models include spiking in the neural network, capturing the electrical characteristics more closely.

CXCL13 Damages Blood Spinal Cord Barrier by Promoting RNF6/Sqstm1‐Ubiquitination Induced Autophagy in Experimental Allergic Encephalomyelitis

Advanced Science, EarlyView.
In multiple sclerosis, the disruption of the blood‐spinal cord barrier (BSCB) induced by CXCL13 facilitates the infiltration of inflammatory cells into the central nervous system, resulting in demyelination and neuronal injury. Mechanistically, the deleterious impact of CXCL13 on the BSCB is associated with a reduction in tight junction protein ...
