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.

Detection in Molecular Communications with Ligand Receptors under Molecular Interference [PDF]

arXiv, 2020
Molecular Communications (MC) is a bio-inspired communication technique that uses molecules to transfer information among bio-nano devices. In this paper, we focus on the detection problem for biological MC receivers employing ligand receptors to infer the transmitted messages encoded into the concentration of molecules, i.e., ligands.

Structure and dynamics of dynorphin peptide and its receptor [PDF]

arXiv, 2019
Dynorphin is a neuropeptide involved in pain, addiction and mood regulation. It exerts its activity by binding to the kappa opioid receptor (KOP) which belongs to the large family of G-protein coupled receptors. The dynorphin peptide was discovered in 1975, while its receptor was cloned in 1993.

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 ...

Factors regulating the activities of the low density lipoprotein receptor and the scavenger receptor on human monocyte-macrophages.

Journal of Lipid Research, 1981
Improved techniques of cell isolation resulted in 90 to 100 million monocytes from a single donor. Addition of low density lipoprotein (LDL) to to cultures of these cells resulted in the down regulation of LDL receptor activity.

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.

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.
