Engineering Concentration‐Dependent Intravitreal Mobility via Cyclic Arginine‐Enriched Nanocarrier Surface Modification: In Vivo Proof‐of‐Concept in a Porcine Large Animal Model

Advanced Healthcare Materials, EarlyView.
In this study, Hammer et al. highlight cyclic‐arginine surface engineering as a highly biocompatible, controllable, and concentration‐dependent regulator of intravitreal nanoparticle mobility in vivo in a translational large animal model. The cyclic arginine surface‐modification supports the development of next‐generation biomaterials for long‐acting ...

Variability of cholesterol accessibility in human red blood cells measured using a bacterial cholesterol-binding toxin

eLife, 2017
Cholesterol partitions into accessible and sequestered pools in cell membranes. Here, we describe a new assay using fluorescently-tagged anthrolysin O, a cholesterol-binding bacterial toxin, to measure accessible cholesterol in human red blood cells ...

Acrolein impairs the cholesterol transport functions of high density lipoproteins.

PLoS ONE, 2015
High density lipoproteins (HDL) are considered athero-protective, primarily due to their role in reverse cholesterol transport, where they transport cholesterol from peripheral tissues to the liver for excretion.

Single session exercise stimulates formation of preβ1-HDL in leg muscle

Journal of Lipid Research, 2003
Physical activity can raise the level of circulating HDL cholesterol. Preβ1-HDL is thought to be either the initial acceptor of cellular cholesterol or virtually the first particle in the pathway of the formation of HDL from apolipoprotein A-I and ...

From Cell‐Derived Vesicles to Hybrid Nanovectors: Biological Membranes as Functional Blueprints for Gene Delivery

Advanced Healthcare Materials, EarlyView.
Biologically derived and hybrid nonviral nanovectors are examined as distinct but convergent design approaches. Integrating synthetic components with biologically functionalized membranes allows efficient interactions with complex cellular environments.

Putting cholesterol in its place: apoE and reverse cholesterol transport [PDF]

Journal of Clinical Investigation, 2006
To avoid toxic overload of cholesterol in peripheral cells, the reverse cholesterol transport pathway directs excess cholesterol through HDL acceptors to the liver for elimination. In this issue of the JCI, a study by Matsuura et al. reveals new features of this pathway, including the importance of the ATP-binding cassette transporter G1 in macrophages

Plasma Gelation as an Overlooked Determinant of Transfection Efficiency in Protein Corona‐Coated Lipid Nanoparticles: Implications for In Vitro–In Vivo Translation

Advanced Healthcare Materials, EarlyView.
Upon contact with plasma, lipid nanoparticles (LNPs) rapidly acquire a protein corona (PC) that redefines their biological identity. In calcium‐containing environments, these coronated particles trigger the formation of a gel‐like plasma network, profoundly altering their transport properties and reducing their effective availability.

Targeting CD300a Signaling With a Phosphatidylserine‐Presenting Hydrogel Rescues Macrophage Dysfunction and Accelerates Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
Schematic illustration of the proposed mechanism: PEG/RGD‐PSLs mimic apoptotic cells to engage PS receptors (notably CD300a), transducing an inhibitory signal that suppresses the MyD88/NF‐κB pathway, leading to global anti‐inflammatory and pro‐reparative effects.

2‐Deoxyglucose Dendrimer‐Enabled Niclosamide Delivery to FRβ‐Expressing Macrophages Alleviates Endometriosis Progression and Associated Hyperalgesia

Advanced Healthcare Materials, EarlyView.
A folic acid (FA)‐conjugated 2‐deoxyglucose dendrimer selectively targets FRβ+ macrophages in endometriotic lesions, enabling precise intracellular delivery of niclosamide. This nonhormonal nanomedicine enhances drug solubility, provides controlled intracellular release, suppresses lesion growth, reduces inflammation and pain, and establishes FRβ ...
