Effect of Nanoparticle Rigidity on the Interaction of Stromal Membrane Particles with Leukemia Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Cell membrane nanoparticles made with stromal cells are prepared and used to target leukemia cells. Deposition of the cell membrane onto rigid silica cores leads to increased uptake both in leukemia cell lines and primary cells from patients. These results show that nanoparticle rigidity affects the interaction between cell membrane nanoparticles and ...

Physical and chemical processes and the morphofunctional characteristics of human erythrocytes in hyperglycaemia [PDF]

open access: yes, 2017
Background: This study examines the effect of graduated hyperglycaemia on the state and oxygen-binding ability of hemoglobin, the correlation of phospholipid fractions and their metabolites in the membrane, the activity of proteolytic enzymes and the ...

Permeation Enhancer‐based Ionogel Shows Remarkable Potential for Oral Insulin Delivery

open access: yesAdvanced Healthcare Materials, EarlyView.
This study proposes a novel formulation of decanoate in an ionic liquid inspired drug delivery system. The formulation demonstrates ideal physicochemical and material properties for oral peptide delivery. Findings indicate that choline decanoate (1:2 molar ratio) forms a viscoelastic gel that enables high oral bioavailability of insulin in rats ...

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.

Phosphorus NMR analysis of phospholipids in detergents.

open access: yesJournal of Lipid Research, 1979
Various detergents can be used to dissolve phospholipids, resulting in very narrow 31PNMR resonances. The resonances are well resolved, allowing identification and quantitative analysis of phospholipids in a mixture.

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 ...

A Targeted Redox‐Active Dual‐Action Pt(IV)‐Mn(II) Prodrug Displays Enhanced In Vivo Anticancer Activity

open access: yesAdvanced Healthcare Materials, EarlyView.
A new oxaliplatin‐based Pt(IV) prodrug bearing a Mn(II) superoxide dismutase mimic is synthesized and studied, in vitro and in vivo, in the context of colorectal cancer. Encapsulation of this prodrug in an easy‐to‐implement PEGylated micelle formulation demonstrated the highest in vivo anticancer activity among all the tested conditions, supporting the

Biomolecule surface patterning may enhance membrane association

open access: yes, 2012
Under dehydration conditions, amphipathic Late Embryogenesis Abundant (LEA) proteins fold spontaneously from a random conformation into alpha-helical structures and this transition is promoted by the presence of membranes.
