Lycium‐Barbarum Polysaccharide‐Loaded Dual‐Crosslinked Rigid Hydrogel Enhances Bone Healing in Diabetic Bone Defects by Scavenging Reactive Oxygen Species

Advanced Healthcare Materials, EarlyView.
A novel hydrogel (HLBP) incorporating natural polysaccharides from goji berries is developed to enhance diabetic bone defect healing. The hydrogel efficiently scavenges ROS, improves osteogenic differentiation, and promotes in vivo bone regeneration. This strategy offers a biocompatible and localized approach, overcoming the challenges of traditional ...

Macrophage SR-BI regulates LPS-induced pro-inflammatory signaling in mice and isolated macrophages

Journal of Lipid Research, 2012
Scavenger receptor BI (SR-BI), an HDL receptor, plays a key role in reverse cholesterol transport. In mice, disruption of SR-BI results in hypersensitivity to lipopolysaccharide (LPS) and bacteria-induced septic shock due to adrenal insufficiency and ...

Functionalized Cerium Oxide Nanoparticles Enhance Penetration into Melanoma Spheroids In Vivo through Angiogenesis

Advanced Healthcare Materials, EarlyView.
Melanoma cell spheroid engraftment is optimized in the chicken chorioallantoic membrane overcoming the complexity of other in vivo models. Using this model, greater penetration of cerium oxide nanoparticles (nanoceria) functionalized with heparin in spheroids is observed via enhancement of vascularization than nanoceria alone.

Deletion of the murine scavenger receptor CD68[S]

Journal of Lipid Research, 2011
Scavenger receptors (ScRs) are a structurally unrelated family of receptors with the ability to bind modified low density lipoprotein (LDL) as well as a broad range of polyanionic ligands.

Self‐Healing Hydrogel Dressing with Solubilized Flavonoids for Whole Layer Regeneration of Diabetic Wound

Advanced Healthcare Materials, EarlyView.
High glucose‐ and acid‐responsive hydrogel with dynamic covalent bond solubilized with flavonoids (Gel‐Flavonoids) is designed for diabetic wound healing. The Gel‐Flavonoids adapt to irregular wound shapes and release antioxidants in high‐glucose environments, effectively reducing reactive oxygen species.

Structures and high and low affinity ligand binding properties of murine type I and type II macrophage scavenger receptors

Journal of Lipid Research, 1993
Macrophage scavenger receptors have been implicated in various macrophage-associated processes, including atherosclerosis and clearance of bacterial endotoxin. They bind to a wide variety of polyanionic ligands and display complex binding characteristics.

Hole Scavenging and Photo-Stimulated Recombination of Electron-Hole Pairs in Aqueous TiO2 Nanoparticles [PDF]

arXiv, 2004
It is shown that 532 nm and 1064 nm laser photoexcitation of trapped electrons generated by 355 nm photolysis of aqueous titania (TiO2) nanoparticles causes rapid photobleaching of their absorbance band in the visible and near IR. This photobleaching occurs within the duration of the laser pulse (3 ns FWHM); it is caused by photoinduced electron ...

Scavenger Receptors [PDF]

, 2015
Scavenger receptors constitute a large family of evolutionally conserved protein molecules that are structurally and functionally diverse. Although scavenger receptors were originally identified based on their capacity to scavenge modified lipoproteins, these molecules have been shown to recognize and bind to a broad spectrum of ligands, including ...

Off‐The‐Shelf Multivalent Nanoconjugate Cancer Vaccine Rescues Host Immune Response against Melanoma

Advanced Materials, EarlyView.
A star‐shaped cross‐linked polyglutamate (StCl) nanocarrier delivers melanoma‐associated peptide antigens via redox‐responsive linkers, inducing lymph node‐targeted antigen presentation. The nanoconjugate activates dendritic cells, promotes effector T‐cell responses, and enables tumor regression even in humanized patient‐derived preclinical models ...
