CD74 Blockade Disrupts Endothelial Migrasome Signaling to Prevent Inflammatory Macrophage Differentiation and Inhibit Atherosclerotic Progression

Advanced Science, EarlyView.
Migrasomes play a crucial role in endothelial‐immune interactions in atherosclerosis. This study identifies migrasomes as amplifiers in the inflammatory cascade, driving immune‐metabolic reprogramming via “migrasome‐APP‐CD74” signaling. Blocking CD74 disrupts migrasome‐mediated signaling, attenuating atherosclerosis progression.

Bleeding is increased in amyloid precursor protein knockout mouse

Research and Practice in Thrombosis and Haemostasis, 2020
Background Amyloid precursor protein (APP) is highly expressed in platelets. APP is the precursor to amyloid beta (Aβ) peptides that accumulate in cerebral amyloid angiopathy and plaques in Alzheimer disease.

SENP6 Maintains Mitochondrial Homeostasis by Regulating Mitochondrial Protein Import Through deSUMOylation of TOM40

Advanced Science, EarlyView.
SUMOylation regulates mitochondrial processes, but its impact on protein import remains unclear. TOM40 is identified, a mitochondrial outer membrane channel protein, as a substrate of deSUMOylase SENP6. TOM40 SUMOylation disrupts outer membrane complex assembly, inhibits protein import, and compromises mitochondrial homeostasis.

Unraveling Tissue‐Specific Fatty Acid Biosynthesis and Inter‐Tissue Crosstalk in Mice through Stable‐Isotope Tracing Metabolomics

Advanced Science, EarlyView.
Biosynthesis rates of 13 FFAs are quantitatively calculated in 15 tissues from glucose and an analytical framework to quantitatively calculate inter‐tissue communications of fatty acids between the liver and other tissues is developed. Moreover, the approach is extended to aging condition and a system‐wide decline of fatty acid synthesis in peripheral ...

Aberrant Mitochondrial Metabolism in Alzheimer's Disease Links Energy Stress with Ferroptosis

Advanced Science, EarlyView.
Alves et al. reveal how energy loss and oxidative stress, two major features of Alzheimer's disease, are connected. Mitochondria controls the flux of the antioxidant glutathione (GSH), via facilitating both its production and consumption. Energy restriction limits GSH synthesis, conferring vulnerability to cell death by ferroptosis, implicated as a ...

Accelerated amyloid deposition, neurofibrillary degeneration and neuronal loss in double mutant APP/tau transgenic mice

Neurobiology of Disease, 2005
Even though the idea that amyloid β peptide accumulation is the primary event in the pathogenesis of Alzheimer's disease has become the leading hypothesis, the causal link between aberrant amyloid precursor protein processing and tau alterations in this ...

NADPH Oxidase Inhibition Promotes Brain Resilience by Attenuating Tauopathy and Neuroinflammation in Alzheimer's Disease

Advanced Science, EarlyView.
CRB‐2131, as a novel Nox inhibitor, suppresses brain oxidation, tauopathy, and neuro‐inflammation, thereby preventing death of mature neurons and promoting regeneration of immature neurons. Ultimately, this fosters a resilient brain and protects cognition.
