Chemotaxis of bio-hybrid multiple bacteria-driven microswimmers

Scientific Reports, 2016
In this study, in a bio-hybrid microswimmer system driven by multiple Serratia marcescens bacteria, we quantify the chemotactic drift of a large number of microswimmers towards L-serine and elucidate the associated collective chemotaxis behavior by ...

Exploring Functionally Enhanced BLP‐Trained Macrophage Subpopulations in S. Aureus Infection: Underlying Mechanisms and Therapeutic Significance

Advanced Science, EarlyView.
BLP‐trained macrophages show augmented resistance to infection, but their mechanisms remain unclear. scRNA‐seq identified 13 BMDM subsets, with two novel anti‐inflammatory/antibacterial subpopulations (C5/C7) emerging post‐BLP training. BLP training activates NRF2, attenuates oxidative stress/ferroptosis, and boosts glycolysis/OXPHOS. Adoptive transfer

Type II Alveolar Epithelial Cells Promote Sepsis‐Induced Immunosuppression in Alveolar Macrophages via Exosomal lncRNA Rmrp Release

Advanced Science, EarlyView.
The S100A4/STAT3 axis promotes Rmrp transcription in AEC‐IIs and Rmrp expression in AEC‐II‐derived exosomes. Upon entry into AMs, Rmrp binds to and blocks the ubiquitination and degradation of ZFP36. Increased ZFP36 induced Pfkfb3 mRNA decay by binding to AREs in the 3′ UTR, curbing glycolysis and immune responses of AMs and aggravating SII and ...

The Pathogenic Roles of Local Vitamin D Metabolism Defect in Valve Inflammation and Calcification

Advanced Science, EarlyView.
This study identifies the valvular interstitial cell populations responsible for valvular calcification induced by hyperphosphatemia and likely aging, uncovers local vitamin D metabolism defect‐induced inflammation as a critical pathogenic factor of calcific aortic valve disease, and highlights active vitamin D and ERK inhibitor as potential preventive

Inhibiting Liver‐Derived C3 Protein Rescues Anesthesia/Surgery‐Induced Cognitive Impairment, Synaptic Disorders, and Microglial Phagocytosis

Advanced Science, EarlyView.
This study provides evidence that anesthesia/surgery can induce the BBB breakdown and promote the release of hepatogenous C3 protein into the blood. This surgical dual factors ultimately drove C3 to cross the damaged BBB and selectively colocalize with C3aR in the hippocampus, which results in structural and functional injury of synapse, C3aR‐mediated ...

Locally excitable Cdc42 signals steer cells during chemotaxis

Nature Cell Biology, 2015
Neutrophils and other amoeboid cells chemotax by steering their front ends towards chemoattractant. Although Ras, Rac, Cdc42 and RhoA small GTPases all regulate chemotaxis, it has been unclear how they spatiotemporally control polarization and steering ...

Sabotaged Integral HSC Heterogeneity Underlies Essential Thrombocythemia Development

Advanced Science, EarlyView.
Single‐cell RNA sequencing (scRNA‐seq) maps how distinct driver mutations remodel hematopoietic stem cell (HSC) programs across essential thrombocythemia (ET). Comparative analysis uncovers both shared and subtype‐specific molecular signatures, identifies a triple‐negative (TN)‐associated HSC population enriched with malignant traits, and reveals the ...

Tie2‐Dependent Mechanisms Influence Leptomeningeal Collateral Dynamics and Reperfusion Following Stroke

Advanced Science, EarlyView.
This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.
