Early Detection of Cell Death Using Transmembrane Water Exchange Magnetic Resonance Imaging

open access: yesAdvanced Science, EarlyView.
Cell death is important in both the development and treatment of cancer. In this study, it is demonstrated for the first time that a specific measurement of the transmembrane water exchange rate using magnetic resonance imaging can be used as an early marker of cell death in mammalian cells, in animals and in human patients. Abstract Cell death plays a

Sex-specific lipidomic signatures in aortic valve disease reflect differential fibro-calcific progression

open access: yesNature Communications
Fibro-calcific aortic valve disease (FCAVD) is the most common valvular heart disease manifesting in pathological remodeling of the aortic valve (AV) leaflets, ultimately leading to aortic stenosis. Although dyslipidemia is a driver of FCAVD pathogenesis,

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

open access: yesAdvanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Red blood cell metabolism in Rhesus macaques and humans: comparative biology of blood storage

open access: yesHaematologica, 2020
Macaques are emerging as a critical animal model in transfusion medicine, because of their evolutionary similarity to humans and perceived utility in discovery and translational science. However, little is known about the metabolism of Rhesus macaque red

Identification and Characterization of an In Silico Designed Membrane‐Active Peptide with Antiviral Properties

open access: yesAdvanced Science, EarlyView.
An evolutionary molecular dynamics platform is used to design P1.6, a membrane‐active peptide that senses lipid packing defects in viral envelopes. P1.6 adopts a stabilized α‐helical structure upon membrane contact, disrupts virus‐like liposomes, and damages HIV‐1 particles.

Advancing Target Identification of Nitrated Phospholipids in Biological Systems by HCD Specific Fragmentation Fingerprinting in Orbitrap Platforms

open access: yesMolecules, 2020
Nitrated phospholipids have recently been detected in vitro and in vivo and associated with beneficial health effects. They were identified and quantified in biological samples by lipidomics methodologies using liquid chromatography-collision-induced ...

Irgm1 Improves Postinfarction Cardiac Repair by Promoting Neutrophil Clearance and Efferocytosis

open access: yesAdvanced Science, EarlyView.
The Irgm1‐PDIA3 axis enhances post‐infarction cardiac repair by accelerating neutrophil clearance and facilitating efferocytosis. Irgm1 holds potential as a prognostic biomarker in MI, and LOC14 may represent a therapeutic option to improve cardiac repair, especially in cases of Irgm1 deficiency.

Lipid‐Facilitated Opening of the ADAM10 Sheddase Revealed by Enhanced Sampling Simulations

open access: yesAdvanced Science, EarlyView.
Phosphatidylserine acts as a lipid trigger to enhance activation of the sheddase ADAM10. By integrating fluorescence spectroscopy assays with enhanced sampling molecular dynamics simulations, this study shows that phosphatidylserine promotes ADAM10 catalytic activity along with expansion of its extracellular domains, enhancing accessibility to scaffold

Tissue- and sex-specific lipidomic analysis of Schistosoma mansoni using high-resolution atmospheric pressure scanning microprobe matrix-assisted laser desorption/ionization mass spectrometry imaging.

open access: yesPLoS Neglected Tropical Diseases, 2020
Schistosomes are human pathogens causing the neglected tropical disease schistosomiasis, which occurs worldwide in (sub-)tropical regions. This infectious disease is often associated with poverty, and more than 700 million people are at risk of infection.
