Colon‐Targeted Natural Polysaccharide‐Berberine Armored Hydrogel for the Treatment of Colitis

open access: yesAdvanced Healthcare Materials, EarlyView.
In this research, a novel hydrogel system targeting the colon is developed, incorporating Rhubarb polysaccharides and berberine‐loaded dendrimer. This hydrogel, forms through intermolecular hydrogen bonding and electrostatic interactions, accumulates in colonic tissues, effectively alleviating pathological immune hyperactivation while modulating gut ...

Covalent Binding of Dexamethasone to Polyimide Improves Biocompatibility of Neural Implantable Devices

open access: yesAdvanced Healthcare Materials, EarlyView.
The covalent binding of dexamethasone to the surface of polyimide represents the electrically inert part of implantable intraneural devices. This ensures a sustained release of the drug for 9 weeks. In vitro and in vivo tests confirm the reduction of the foreign body reactions and the improved biocompatibility of dexamethasone functionalized polyimide.

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 ...

Conditioned Media from Mechanically Stimulated Macrophages Upregulate Osteogenic Genes in Human Mesenchymal Stromal Cells

open access: yesAdvanced Healthcare Materials, EarlyView.
Bone fracture healing is a complex, timely orchestrated scenario involving multiple cell types and a plethora of cytokines and regulatory factors. To gain further insight, an in vitro model to a) study macrophage polarization under mechanical load in a fibrin hydrogel and b) subsequently assess the effect of conditioned media derived from macrophages ...

Progress of Immune‐Inducible Biomaterials for Post‐Ablation Cancers

open access: yesAdvanced Healthcare Materials, EarlyView.
The presence of residual tumors after ablative therapies poses a significant challenge, generally resulting in recurrence and metastases. This review offers a concise overview of immune‐inducible biomaterials from the perspective of the cancer‐immunity cycle, and how they enhance antitumor immunity through diverse mechanisms following ablative ...
