A Dynamic DNA Nano‐Antioxidant Targeting Galectin‐3 Attenuates Liver Fibrosis via Reducing Macrophage Oxidative Stress

open access: yesAdvanced Science, EarlyView.
This study developed a dynamic DNA nano‐antioxidant (DDN) for Galectin‐3 siRNA delivery, specifically targeting hepatic macrophages to suppress ROS‐driven fibrosis. DDN enhanced hepatic accumulation, restored NRF2 signaling, and attenuated oxidative stress, collagen deposition, and fibrotic progression in a CCl4‐induced cirrhosis model, demonstrating ...

Emergence of highly profibrotic and proinflammatory Lrat+Fbln2+ HSC subpopulation in alcoholic hepatitis

open access: yesHepatology, EarlyView., 2022
Lrat+ quiescent hepatic stellate cells (qHSC) give rise to Lrat+Fbln2+ activated HSC (aHSC) in alcohol‐associated hepatitis and this subpopulation is highly profibrotic, inflammatory, and immunoregulatory based on their single cell transcriptomic profile. Abstract Background and Aims Relative roles of HSCs and portal fibroblasts in alcoholic hepatitis (

Measuring cell adhesion forces with the atomic force microscope at the molecular level [PDF]

open access: yes, 2002
In the past 25 years many techniques have been developed to characterize cell adhesion and to quantify adhesion forces. Atomic force microscopy (AFM) has been used to measure forces in the pico-newton range, an experimental technique known as force ...

CHB‐Induced Immune Zonation Chaos Elicited LXRα‐mediated Lipid Metabolism Disorders in Kupffer Cells to Induce Cancer Stem Cell Formation

open access: yesAdvanced Science, EarlyView.
By profiling the spatiotemporal hepatic landscape of CHB mouse models, the originally peri‐portal localized KCs migrated to the peri‐central in a CXCL9‐CXCR3‐dependent manner, facilitating their interaction with HBV+ hepatocytes. The interaction promoted LMD in KCs through ASGR1‐induced LXRα degradation, which, in turn, induced CSC formation via Stat3 ...

Decoding a Gut Commensal Signal: Structural and Immunological Profiling of Segatella Copri Lipopolysaccharide

open access: yesAngewandte Chemie, EarlyView.
The lipopolysaccharide (LPS) of Segatella copri is a structurally unique, immunomodulatory glycoconjugate. Combining mass spectrometry (MS), nuclear magnetic resonance (NMR), and cytometry by time‐of‐flight (CyTOF), we uncover a rough‐type LPS with reduced TLR4 agonism and selective monocyte effects, further highlighting the key role of LPS chemistry ...

Sensing ligand binding to a clinically relevant lectin by tryptophan fluorescence anisotropy [PDF]

open access: yes, 2011
Increasing insights into the involvement of endogenous lectins in disease processes fuel the interest to develop potent inhibitors. As a consequence, robust assay procedures are required. Due to their activity as adhesion/growth-regulatory effectors this

Use of lectins in immunohematology

open access: yesAsian Journal of Transfusion Science, 2016
Lectins are carbohydrate binding proteins present in seeds of many plants, especially corals and beans, in fungi and bacteria, and in animals. Apart from their hemagglutinating property, a wide range of functions have been attributed to them. Their importance in the area of immunohematology is immense. They are used to detect specific red cell antigens,

Enhanced Single‐Particle Upconversion Imaging via Energy Migration Boosting

open access: yesAdvanced Science, EarlyView.
A core‐shell‐shell Yb3⁺/Er3⁺ UCNP architecture is engineered to balance energy migration and back energy transfer, yielding more than a tenfold enhancement in single‐particle brightness. Leveraging these optimized probes, it achieves long‐term, high‐resolution single‐particle tracking in live neurons, uncovering coordinated transport mechanisms of ...

Effect of proteins from the red seaweed Hypnea musciformis (Wulfen) Lamouroux on the growth of human pathogen yeasts

open access: yesBrazilian Archives of Biology and Technology, 2006
A protein fraction, rich in lectin, obtained from the red seaweed Hypnea musciformis by precipitation with ammonium sulfate (F40/70) was screened for chitinase and beta-1,3-glucanase activity and assessed for antifungal potential against the human ...

MUC15 Ectodomain Architecture Regulates Integrin Clustering to Control Cancer Metastasis

open access: yesAdvanced Science, EarlyView.
This study uncovers a size‐dependent adhesion paradigm, demonstrating that the glycocalyx protein MUC15 suppresses pancreatic cancer progression by attenuating integrin activation, focal adhesion assembly, and YAP mechanotransduction. Integrating computational modeling and experimental validation, the work reveals a mechanical mechanism by which MUC15 ...
