Chemoproteomic discovery of a brain‐penetrant, covalent NLRP3 inhibitor that binds a novel allosteric pocket

British Journal of Pharmacology, EarlyView.
NLRP3 is a promising inflammatory target, but existing inhibitors lack diversity and brain penetrance, and none are approved. Using chemoproteomics, we discovered a novel series that binds to Cys463 in a previously uncharacterized pocket. Compounds showed nanomolar potency, brain exposure, and in vivo suppression of IL‐1β, supporting neuroinflammatory ...

TOP1MT rs2293925 is an enhancer‐active regulatory SNP that shapes mitochondrial R‐loop dynamics

The FEBS Journal, EarlyView.
This study shows how a common genetic variant of mitochondrial topoisomerase 1 (TOP1MT rs2293925) can influence mitochondrial gene regulation, DNA topology, and formation of noncanonical nucleic acid structures such as R‐loops. By linking this enhancer‐active variant to mitochondrial nucleic acid stress in cellular contexts relevant to amyotrophic ...

Lipid Diffusion in Supported Lipid Bilayers: A Comparison between Line-Scanning Fluorescence Correlation Spectroscopy and Single-Particle Tracking

Membranes, 2015
Diffusion in lipid membranes is an essential component of many cellular process and fluorescence a method of choice to study membrane dynamics. The goal of this work was to directly compare two common fluorescence methods, line-scanning fluorescence ...

Using confocal microscopy and image processing to measure properties of sub‐resolution cell structures: Application to cardiac transverse tubules

Journal of Microscopy, EarlyView.
Abstract Confocal microscopes increase the resolution of images by rejecting unwanted data from the out of focus regions of the specimen. This incurs a penalty in the recorded signal to noise ratio that may be partially ameliorated by inputting additional information during image processing.

Photon-Counting Arrays for Time-Resolved Imaging

Sensors, 2016
The paper presents a camera comprising 512 × 128 pixels capable of single-photon detection and gating with a maximum frame rate of 156 kfps. The photon capture is performed through a gated single-photon avalanche diode that generates a digital pulse upon

Established and Emerging Biomarkers to Characterize Persons at Risk for Obesity—Paving the Way for Targeted Clinical Intervention Trials—A Comprehensive Position Paper

Obesity Reviews, EarlyView.
ABSTRACT Despite all efforts, obesity remains a major health concern worldwide, with continuously increasing rates, affecting approx. 14% of the total world population, being as high as 43% in some countries. As obesity is related to numerous comorbidities, including type 2 diabetes, cardiovascular diseases, and some types of cancer, the consequences ...

Understanding extracellular vesicle biology, isolation, and characterization: The theory of EV‐erything

Periodontology 2000, EarlyView.
Abstract Background Extracellular vesicles (EVs), especially exosomes, are nanoparticles increasingly recognized as key regulators of intercellular communication in both physiological and pathological aspects. Despite rapid progress, inconsistencies in nomenclature, isolation, and characterization continue to restrict translational advancement.

Modification of the Transcription Factor FOXL2 at Serines 101 and 107 Disables DNA Binding, Leads to Nucleolar Relocalization, and Rewires Granulosa‐Cell Programs

The FASEB Journal, Volume 40, Issue 15, 15 August 2026.
PKC‐mediated phosphorylation of FOXL2 weakens DNA binding, alters subnuclear localization and protein interactions, and reshapes FOXL2‐dependent transcriptional programs in granulosa cells, supporting a reversible mechanism that modulates FOXL2 activity through phosphorylation of its DNA‐binding domain. ABSTRACT FOXL2 is a forkhead transcription factor

Assessing Vancomycin‐Formyl Peptide Conjugate Binding to the Surface of Resistant Staphylococcus aureus via Flow Cytometry

ChemBioChem, Volume 27, Issue 15, 14 August 2026.
A flow cytometry technique was developed to measure the binding of vancomycin‐formyl peptide conjugates to the surface of resistant Staphylococcus aureus. Binding results indicate that the labelling site of the vancomycin targeting element has a major effect on binding to the bacterial cell wall, which correlates with reduced antibiotic activity ...
