Artificial nonenzymatic antioxidant Prussian blue/KGM-BSA nanocomposite hydrogel dressing as ROS scavenging for diabetic wound healing.

International Journal of Biological Macromolecules
The process of diabetic wound healing was influenced by the excessive proliferation of reactive oxygen species (ROS). Therefore, in the process of healing diabetic wounds, it was crucial to removing ROS. This study designed composited nanoparticles: KBP,

Compensatory Mitophagy via NEDD4/HIF‐1α/BNIP3 Pathway Restrains EndMT and Renal Allograft Interstitial Fibrosis Induced by TNFα

Advanced Science, EarlyView.
The role of TNFα in the process of renal allograft interstitial fibrosis is complex and multifaceted. As it can promote renal allograft interstitial fibrosis by inducing mitochondrial dysfunction and EndMT, and also mediating compensatory mitophagy through the NEDD4–HIF‐1α–BNIP3 pathway, which clears damaged mitochondria and inhibits EndMT, thereby ...

Integrative analyses of expression patterns of ROS-scavenging genes suggest their coordinated regulation confer drought tolerance in OsCATA-RNAi transgenic rice plants

Environmental and Experimental Botany
Environmental stresses-induced overproduction of reactive oxygen species (ROS) leads to severe oxidative damage to cellular components. As a key ROS, H₂O₂ functions as a destructive oxidant or a vital regulatory molecule in a concentration-dependent ...

Copper‐Driven Epithelial Barrier Disruption: A Novel Mechanism of COPD Acute Exacerbations Mediated by the TNF‐α/ATP7A Axis

Advanced Science, EarlyView.
This study reveals a copper‐driven mechanism of COPD acute exacerbations mediated by the TNF‐α/ATP7A axis. TNF‐α suppresses the copper transporter ATP7A via competitive NF‐κB/CREB1/CBP signaling, resulting in intracellular copper accumulation, mitochondrial oxidative stress, and epithelial barrier disruption.

Aβ42 and ROS dual-targeted multifunctional nanocomposite for combination therapy of Alzheimer’s disease

Journal of Nanobiotechnology
Amyloid-β (Aβ) readily misfolds into neurotoxic aggregates, generating high levels of reactive oxygen species (ROS), leading to progressive oxidative damage and ultimately cell death. Therefore, simultaneous inhibition of Aβ aggregation and scavenging of

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

Advanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,
