Role of MicroRNAs in innate neuroprotection mechanisms due to preconditioning of the brain

open access: yesFrontiers in Neuroscience, 2015
Insults to the brain that are sub-threshold for damage activate endogenous protective pathways, which can temporarily protect the brain against a subsequent harmful episode.

Data‐Driven Printability Modeling of Hydrogels for Precise Direct Ink Writing Based on Rheological Properties

open access: yesAdvanced Science, EarlyView.
A predictive model for 3D printability is developed by integrating rheological analysis, including the Large Amplitude Oscillatory Shear (LAOS) test, with machine learning. With prediction errors under 10%, the model shows that post‐extrusion recovery controls horizontal printability, while high‐strain‐rate nozzle flow dictates vertical printability ...

A Microbiota‐ and IL‐15‐Dependent Innate‐Like B Cell Progenitor Expressing E4BP4

open access: yesAdvanced Science, EarlyView.
This work identifies CD3.NKp46.CD19.NK1.1. NK‐B cells enriched in PDK1‐deficient yet present in wild‐type bone marrow. IL‐15 (via CD122) and TLR9‐microbiota signaling maintain their E4BP4 expression. These cells demonstrate innate immunity, preferentially differentiate into B cells, and unveil a novel microbiota‐ and IL‐15‐dependent regulatory pathway ...

Fast and accurate surface normal integration on non-rectangular domains

open access: yesComputational Visual Media, 2017
The integration of surface normals for the purpose of computing the shape of a surface in 3D space is a classic problem in computer vision. However, even nowadays it is still a challenging task to devise a method that is flexible enough to work on non ...

A Self‐Organized Liquid Reaction Container for Cellular Memory

open access: yesAdvanced Science, EarlyView.
How cells restore epigenetic information lost during replication is not known. This work proposes a mechanism based on the formation of biomolecular condensates. These condensates are induced by the chromosome itself and serve as reaction vessels for reconstructing missing epigenetic markers.

Sphingosine‐1‐Phosphate Receptor 1 Regulates Cardiac Function by Modulating Ca2+ Sensitivity and Na+/H+ Exchange and Mediates Protection by Ischemic Preconditioning

open access: yesJournal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundSphingosine‐1‐phosphate plays vital roles in cardiomyocyte physiology, myocardial ischemia–reperfusion injury, and ischemic preconditioning. The function of the cardiomyocyte sphingosine‐1‐phosphate receptor 1 (S1P1) in vivo is unknown. Methods

Immunomodulatory Hydrogel Coating with SeNPs and Lithium Silicate Synergistically Promotes Osseointegration and Prevents Infection on Titanium Implants

open access: yesAdvanced Science, EarlyView.
This study introduces a multifunctional hydrogel coating (Lap‐CMCSMA/GelMA@SeNPs) that scavenges ROS, modulates immune responses, and shows strong antibacterial activity. It effectively restores the peri‐implant microenvironment. The coating exhibits excellent biocompatibility and promotes osteogenic differentiation.

Cancer Stem Cells Shift Metabolite Acetyl‐Coenzyme A to Abrogate the Differentiation of CD103+ T Cells

open access: yesAdvanced Science, EarlyView.
Lei et al. demonstrate that cancer stem cells (CSCs) play a pivotal role in impairing the differentiation of CD103+ T cells in patients with non‐small‐cell lung cancer. The key mechanism involves CSC‐derived acetyl‐CoA, which disrupts CD103+ T cell differentiation by sequentially inducing acetylation and ubiquitination of the Blimp‐1 protein. Targeting
