Biomimetic Ru‐Mn Nanozyme with Cascade Catalytic Activity Attenuates Secondary Brain Injury in Intracerebral Hemorrhage

Advanced Science, EarlyView.
Ru–Mn composite nanozymes are engineered to mimic dual‐enzyme cascade catalysis, enabling efficient ROS clearance and neuroinflammation suppression. In collagenase‐ and autologous blood‐induced ICH mouse models, intranasal and intravenous administration reduced hematoma volume, preserved BBB integrity, and improved neurological recovery.

Hepatic cholesterol and bile acid metabolism and intestinal cholesterol absorption in scavenger receptor class B type I-deficient mice

Journal of Lipid Research, 2001
The scavenger receptor class B type I (SR-BI), which is expressed in the liver and intestine, plays a critical role in cholesterol metabolism in rodents.

A Microbial Lipid‐ATP Synthase Axis Fuels NK Cell Antitumor Activity

Advanced Science, EarlyView.
This study focuses on the mechanism by which gut microbiota‐derived outer membrane vesicles (OMVs) regulate NK cell antitumor activity. B. intestinalis is identified to decrease extra‐intestinal tumor growth via its OMVs enriched in sphingosine (SP).

HDL-mediated cholesterol uptake and targeting to lipid droplets in adipocytes

Journal of Lipid Research, 2003
Adipocytes express high levels of the HDL scavenger receptor class B type I in a differentiation-dependent manner. We thus have analyzed the routes of HDL cholesterol trafficking at different phases of adipocyte differentiation in the 3T3-L1 cell line ...

Characterization of antibody-mediated neutralization directed against the hypervariable region 1 of hepatitis C virus E2 glycoprotein [PDF]

, 2010
The hypervariable region 1 (HVR1) comprising the first 27 aa of E2 glycoprotein is a target for neutralizing antibodies against hepatitis C virus (HCV), but the mechanisms of this neutralization in the cell-culture-infectious genotype 2a strain JFH1 ...

Disruption of Treg Homeostasis in Rheumatoid Arthritis via Ferroptosis‐Mediated ETC Collapse and TXK‐STAT3/PLCγ1 Activation

Advanced Science, EarlyView.
In rheumatoid arthritis, synovial Tregs accumulate but are functionally impaired due to iron overload‐induced ferroptosis. This triggers mitochondrial dysfunction and TXK tyrosine kinase‐mediated signaling, leading to Treg destabilization and inflammation.

Secretory phospholipase A2 increases SR-BI-mediated selective uptake from HDL but not biliary cholesterol secretions⃞

Journal of Lipid Research, 2008
High density lipoprotein cholesterol represents a major source of biliary cholesterol. Secretory phospholipase A2 (sPLA2) is an acute phase enzyme mediating decreased plasma HDL cholesterol levels. Clinical studies reported a link between increased sPLA2

Interaction of scavenger receptor class B type I with peroxisomal targeting receptor Pex5p

, 2003
Scavenger receptor class B type I (SR-BI) is an HDL receptor that mediates selective HDL lipid uptake. Peroxisomes play an important role in lipid metabolism and peroxisomal targeting signal type 1 (PTS1)-containing proteins are translocated to ...
