Ultrasmall iron-gallic acid coordination polymer nanoparticles for scavenging ROS and suppressing inflammation in tauopathy-induced Alzheimer's disease.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder globally, with no effective treatment available yet. A crucial pathological hallmark of AD is the accumulation of hyperphosphorylated tau protein, which is deteriorated by reactive oxygen species (ROS) and neuroinflammation in AD progression. Thus, alleviation of ROS and inflammation has become a potential therapeutic strategy in many studies.

Controllable -Polarized Spin Current in Artificially Structured Ferromagnetic Oxide with Strong Spin-Orbit Coupling.

Realizing field-free switching of perpendicular magnetization by spin-orbit torques is crucial for developing advanced magnetic memory and logic devices. However, existing methods often involve complex designs or hybrid approaches, which complicate fabrication and affect device stability and scalability. Here, we propose a novel approach using -polarized spin currents for deterministic switching of perpendicular magnetization through interfacial engineering.

Hepatoma cell-derived exosomal SNORD52 mediates M2 macrophage polarization by activating the JAK2/STAT6 pathway.

Background: A recent study revealed the oncogenic role of box C/D small nucleolar RNA 52 (SNORD52) in hepatocellular carcinoma (HCC) by facilitating the aggressive phenotypes of hepatoma cells. However, the potential role of exosomal SNORD52 in macrophage polarization during HCC progression remains poorly understood.

Methods: Exosomes were isolated from hepatoma cells.

Two-component system GrpP/GrpQ promotes pathogenicity of uropathogenic Escherichia coli CFT073 by upregulating type 1 fimbria.

Uropathogenic Escherichia coli (UPEC) is a major cause of urinary tract infections (UTIs). Invasion into bladder epithelial cells (BECs) on the bladder luminal surface via type 1 fimbria is the first critical step in UPEC infection. Although type 1 fimbria expression increases during UPEC invasion of BECs, the underlying regulatory mechanisms remain poorly understood.
