Pulmonary Delivery of siRNA Anti‐TNFα‐loaded Lipid Nanoparticles for Rapid Recovery in Murine Acute Lung Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
In a murine model of acute lung injury, pulmonary administration of lipid nanoparticles carrying TNFα siRNA enables targeted delivery to immune cells. The study emphasises the importance of optimizing LNP distribution and delivery timing to improve therapeutic outcomes and develop emergency therapies for lung hyperinflammation.

Influence of Phospholipid and Protein Constituents on Tribological Properties of Artificial Hydrogel Cartilage Material

open access: yesJournal of Biomechanical Science and Engineering, 2013
In this study, the influence of phospholipid and protein constituents on friction and wear behavior of artificial hydrogel cartilage was investigated. A sliding pair of an ellipsoidal specimen of poly (vinyl alcohol) (PVA) hydrogel and a flat specimen of

Mechanobiologically Engineered Mimicry of Extracellular Vesicles for Improved Systemic Biodistribution and Anti‐Inflammatory Treatment Efficacy in Rheumatoid Arthritis

open access: yesAdvanced Healthcare Materials, EarlyView.
Triblock copolymer‐reinforced liposomal mimics of extracellular vesicles are engineered with tunable membrane elasticity. A semi‐elastic formulation (Tri‐ARTEX8:2) co‐encapsulating stem cell cytosolic extract and AntagomiR155 targets inflamed joints via the ELVIS effect, reprograms macrophages from M1 to M2, and markedly alleviates collagen‐induced ...

Cell Surface Thiol Engineering Mechanoregulates Myogenic Differentiation via the FAK–PI3K–AKT Axis

open access: yesAdvanced Healthcare Materials, EarlyView.
Schematic diagram illustrating how cell surface modification of skeletal muscle progenitor cells through TCEP treatment reveals enhanced cell adhesion, intracellular tension, and myogenesis at 19.66 kPa stiffness, leading to optimal cell fusion. In contrast, no significant changes are observed in the softer (10.61 kPa) or stiffer (49.4 kPa) matrices ...

Chemistry of phospholipid oxidation

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2012
The oxidation of lipids has long been a topic of interest in biological and food sciences, and the fundamental principles of non-enzymatic free radical attack on phospholipids are well established, although questions about detail of the mechanisms remain.

Molecular Mechanisms of Extracellular Vesicle Biogenesis and Their Impact on the Design of Custom EVs

open access: yesAdvanced Healthcare Materials, EarlyView.
Extracellular vesicles (EVs) are pivotal mediators of intercellular communication and disease, yet the fundamental mechanisms controlling their biogenesis and cargo selection remain unclear. This limitation hinders their diagnostic utility and therapeutic development.

A Novel Brain Penetrable Nanocarrier Delivers Brain‐Derived Neurotrophic Factor to Treat Alzheimer's Disease

open access: yesAdvanced Healthcare Materials, EarlyView.
A novel blood‐brain barrier‐penetrating terpolymer nanoparticle to deliver brain‐derived neurotrophic factor (BDNF) for the treatment of Alzheimer's disease (AD) is designed. The BDNF‐TPN significantly enhances BDNF accumulation in the brain following intravenous injection, reduces apoptosis and neuroinflammation, thus promoting neuronal survival and ...

Imiquimod‐Loaded Phospholipid‐Free Small Unilamellar Vesicles Activate the Tumor Immune Microenvironment to Treat Liver Cancer and Liver Metastases

open access: yesAdvanced Healthcare Materials, EarlyView.
Imiquimod‐loaded nanoparticles (PFSUV‐IMQ) are found to decrease liver metastasis and liver tumor burden when administered intravenously. Flow cytometry, RNA‐seq and various experiments show that the anti‐tumor response is immune‐mediated by activating dendritic cells resulting in increased CD8 T cell infiltration and activity.

Phospholipid scramblase: An update

open access: yesFEBS Letters, 2010
The best understood consequence of the collapse of lipid asymmetry is exposure of phosphatidylserine (PS) in the external leaflet of the plasma membrane bilayer, where it is known to serve at least two major functions: providing a platform for development of the blood coagulation cascade and presenting the signal that induces phagocytosis of apoptotic ...
