Novel Pseudotaxis Mechanisms Improve Migration of Straight-Swimming Bacterial Mutants Through a Porous Environment

mBio, 2015
Bacterial locomotion driven by flagella is given directionality by the chemotaxis signal transduction network. In the classic plate assays of migration in porous motility agar, efficient motility is compromised in chemotaxis mutants of diverse bacteria ...

CCL5hi Macrophages Interact with CD8+ T Cells and Potentiate Responsiveness to PD‐1 Blockade Plus Chemotherapy in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
This study has characterized a functionally distinct macrophage subset, termed CCL5hi macrophages, and elucidated the underlying mechanisms of a regulatory feedback loop that interconnects IFN‐γ, CCL5hi macrophages, and CD8+ T cells within the TME of ESCC undergoing immunochemotherapy.

CRISPR‐MI and scRNA‐Seq Reveal TREM2's Function in Monocyte Infiltration and Macrophage Apoptosis During Abdominal Aortic Aneurysm Development

Advanced Science, EarlyView.
A method is developed for conducting genome‐wide CRISPR/Cas9 screening of monocyte infiltration in vivo (CRISPR‐MI) that is easily adaptable across a variety of disease models. Through the combination of CRISPR‐MI and scRNA‐Seq, this study discovers that Trem2 is a key regulator of early monocyte infiltration in abdominal aortic aneurysm (AAA ...

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

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

PVC Nanoplastics Exposure Exacerbates Asthma through R‐Loop Accumulation and Subsequent STING Activation in Macrophages

Advanced Science, EarlyView.
Polyvinyl chloride (PVC) nanoplastics (NPs) are shown to aggravate allergic airway inflammation in asthma by triggering R‐loop accumulation and activating the cGAS‐STING pathway in macrophages. This study reveals a novel immunotoxic mechanism linking environmental plastic exposure to asthma pathogenesis and highlights potential molecular targets for ...

Deciphering the Role and Mechanism of Decidual Monocyte‐Derived Macrophage Infiltration in Obstetric Antiphospholipid Syndrome at Single‐Cell Resolution

Advanced Science, EarlyView.
This study uncovers a novel mechanism and therapeutic targets in obstetric antiphospholipid syndrome (OAPS). Antiphospholipid antibody/ß2‐glycoprotein I complex boosts CCL2 and TNF‐α expression in decidual macrophages via TLR4‐NF‐κB. CCL2 accumulates on endothelial surfaces via ACKR1, recruiting monocyte‐derived CCR2+ macrophages, driving inflammation,

Integration of the Second Messenger c-di-GMP into the Chemotactic Signaling Pathway

mBio, 2013
Elevated intracellular levels of the bacterial second messenger c-di-GMP are known to suppress motility and promote sessility. Bacterial chemotaxis guides motile cells in gradients of attractants and repellents over broad concentration ranges, thus ...
