Subventricular Zone‐on‐a‐Chip: A Model to Study Neurogenesis Disruption in Neonatal Intraventricular Hemorrhage

Advanced Science, EarlyView.
A human subventricular zone‐on‐a‐chip is developed to model intraventricular hemorrhage (IVH) in preterm infants. This platform enables the study of inflammation‐driven neurogenic disruption. Exposure to hemorrhagic cerebrospinal fluid and red blood cell lysate activated inflammatory pathways, with IL1B emerging as a key mediator.

A partial gene deletion of SLC45A2 causes oculocutaneous albinism in Doberman pinscher dogs. [PDF]

PLoS ONE, 2014
The first white Doberman pinscher (WDP) dog was registered by the American Kennel Club in 1976. The novelty of the white coat color resulted in extensive line breeding of this dog and her offspring.

Retinoic Acid Reprograms Mast Cells Toward a Proinflammatory State to Enhance Antitumor Immunity

Advanced Science, EarlyView.
Proinflammatory mast cells represent an MHC‐IIhigh, cytokine‐producing mast cell subset associated with improved survival and enhanced responses to anti‐PD‐1 therapy. Retinoic acid drives their polarization, enabling antigen uptake and presentation, and T cell recruitment and activation, collectively promoting adaptive anti‐tumor immunity.

gnSPADE: Incorporating Gene Network Structures Enhances Reference‐Free Deconvolution in Spatial Transcriptomics

Advanced Intelligent Systems, EarlyView.
gnSPADE integrates gene‐network structures into a probabilistic topic modeling framework to achieve reference‐free cell‐type deconvolution in spatial transcriptomics. By embedding gene connectivity within the generative process, gnSPADE enhances biological interpretability and accuracy across simulated and real datasets, revealing spatial organization ...

Pro‐Inflammatory c‐Met+ CD4 T Cells in Multiple Sclerosis

Annals of Neurology, EarlyView.
Objective Hepatocyte growth factor (HGF) binds exclusively the c‐Met surface receptor, and the HGF/c‐Met axis regulates T cell function in autoimmune diseases. We analyzed c‐Met expression on human CD4 T cells in the blood and cerebrospinal fluid (CSF) from patients with multiple sclerosis (MS) versus non‐inflammatory neurological disease (NIND), to ...
