Platelet senescence and phosphatidylserine exposure [PDF]

Transfusion, 2010
BACKGROUND: The exposure of phosphatidylserine occurs during platelet (PLT) activation and during in vitro storage. Phosphatidylserine exposure also occurs during apoptosis after the release of mitochondrial cytochrome c. We have examined the role of cytochrome c release, mitochondrial membrane potential (ΔΨm), and cyclophilin D (CypD) in ...

Single‐Cell Insights Into Macrophage Subtypes in Pulmonary Infections

Advanced Science, EarlyView.
This review highlights the dynamic plasticity of macrophages during pulmonary infections and proposes an integrative framework defining six functional subtypes: Inflam‐Ms, Hub‐Ms, Reg‐Ms, Prolif‐Ms, Memory‐Ms, and Senesc‐Ms. Single‐cell omics delineate their distinct roles in homeostasis and infection, refining our understanding of macrophage ...

Development of Endogenous Protein Probes for Characterizing Surface Proteins and Cellular Interactors of Extracellular Vesicles

Advanced Science, EarlyView.
The proximity labeling enzyme APEX2 is displayed on extracellular vesicle (EV) surfaces via genetic fusion with EV‐sorting scaffolds, enabling in situ biotinylation of native surface proteins, adsorbed corona components, and interacting cellular proteins.

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

Nature 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,

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

Molecules, 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 ...

Punicalagin Enhances Autophagy Through Sirtuin 1/FoxO3a Axis to Inhibit Intracellular Mycobacterium Abscessus Infection

Advanced Science, EarlyView.
Punicalagin, a pomegranate molecule, helps the body fight Mycobacterium abscessus. It preferentially boosts interstitial macrophages in the lung, stabilizing mitochondria and switching on the autophagy via SIRT1/FoxO3a, which lowers bacterial load without directly killing bacteria.

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

Advanced 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

Nanoparticle‐Based Tolerogenic Vaccines: Next‐Generation Strategies for Autoimmune and Allergic Disease Therapies

Angewandte Chemie, EarlyView.
Nanoparticle‐based tolerogenic vaccines harness controlled antigen delivery and immunomodulation to establish tolerance in autoimmunity and allergy. This review outlines how nanoparticle design (size, shape, composition, administration route) influences biodistribution and immune‐cell targeting.

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

Haematologica, 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

Dynamics of phagocytosis mediated by phosphatidylserine

Biochemical Society Transactions, 2022
Phagocytosis triggered by the phospholipid phosphatidylserine (PS) is key for the removal of apoptotic cells in development, tissue homeostasis and infection. Modulation of PS-mediated phagocytosis is an attractive target for therapeutic intervention in the context of atherosclerosis, neurodegenerative disease, and cancer.
