Sense–Analyze–Respond–Actuate (SARA) Paradigm: Proof of Concept System Spanning Nanoscale and Macroscale Actuation for Detection of Escherichia coli in Aqueous Media

Actuators, 2020
Foodborne pathogens are a major concern for public health. We demonstrate for the first time a partially automated sensing system for rapid (~17 min), label-free impedimetric detection of Escherichia coli spp.

CD112 Lactylation Drives Dual Immune Evasion From CD8+ T Cells and NK Cells

Advanced Science, EarlyView.
AARS2 functions as an intracellular lactate sensor and lactyltransferase, catalyzing CD112 K412 lactylation to block ubiquitination‐dependent degradation and stabilize CD112. This pathway suppresses CD8+ T‐cell and NK‐cell cytotoxicity, enabling dual immune evasion.

Checkpoint‐Directed Glycoengineering Reprograms the Vascular Lumen for Siglec‐Mediated Immune Regulation

Advanced Science, EarlyView.
Checkpoint‐directed glycoengineering installs sialylated ligands on the donor vascular lumen during ex vivo preservation, creating a localized Siglec‐7/9‐engaging interface. The engineered glycocalyx suppresses immune‐cell activation, complement deposition, and microvascular injury in arterial and kidney allografts while preserving endothelial ...

lectin [PDF]

, 1986
The combining region ofArtocarpus integrifolia lectin has been studied by using the ligand-induced changes in the fluorescence of the lectin. The saccharide binding properties of the lectin show that C-l, C-2, C-4, and C-6 hydroxyl groups of D-galactose ...

Tumor‐Intrinsic HEXB Drives Endothelial‐To‐Mesenchymal Transition and Confers Resistance to Anti‐Angiogenic Therapy in Glioblastoma

Advanced Science, EarlyView.
This study elucidates how glioblastoma tumors develop resistance to anti‐VEGF therapy through endothelial‐to‐mesenchymal transition (Endo‐MT). The researchers identify a novel signaling pathway where tumor‐derived HEXB stabilizes HSP60 to drive this vascular reprogramming.

Enzyme‐Linked Cycloaddition Assay (ELCA) for Rapid, Ultra‐Sensitive Monitoring of Secreted Sialoglycoproteins

Advanced Science, EarlyView.
Secreted glycoproteins report on cellular state faster than the cell surface, yet remain hard to measure. The Enzyme‐Linked Cycloaddition Assay (ELCA) combines metabolic azide labeling with click chemistry in an ELISA‐like microplate format, resolving sialylation changes within minutes for 1‐2 EUR per sample.

An Immunoreactive Protein to Wheat-Germ Agglutinin Antibody Is Induced in Oat Roots Following Invasion of the Cereal Cyst Nematode Heterodera avenae, and by Jasmonate

Molecular Plant-Microbe Interactions, 1997
A protein that cross-reacts to a wheat-germ agglutinin antibody was induced in oat roots following the invasion of second-stage juveniles (J2) of the cereal cyst nematode Heterodera avenae.

A Chiral Virus‐Like Nanoplatform That Broadly Mediates Antibiotic Delivery to the Brain for Bacterial Meningitis Therapy

Advanced Science, EarlyView.
Chiral virus‐mimicking mesoporous silica nanostructures (CVSNs) efficiently transport diverse antibiotics across the blood–brain barrier (BBB) into brain parenchyma and cerebrospinal fluid. By enhancing delivery to microglia and astrocytes, CVSNs improve antibiotic bioavailability and therapeutic efficacy against both Gram‐negative and Gram‐positive ...
