Enzymatic Basis for the Oxidative Branch of Aromatic Amino Acid Fermentation Leading to p‐cresol Formation

Advanced Science, EarlyView.
In anaerobic bacteria, tyrosine serves as an electron donor in the oxidative Stickland fermentation branch, generating p‐hydroxyphenylacetate, ATP and reduced ferredoxin for decarboxylation into p‐cresol. ABSTRACT The phenolic metabolite p‐cresol is a byproduct of tyrosine fermentation by certain strictly anaerobic bacteria, including the human gut ...

Self‐Amplifying Redox Cycle Triggers Ferroptosis/Cuproptosis Synergy for Enhanced Bacterial Eradication

Advanced Science, EarlyView.
This study designs a targeted nanocomposite (ct@HMCF‐Dex) that responds to acidic infection microenvironments, releasing components which amplify oxidative stress. It disrupts bacterial redox balance, chelates metals to sustain lipid peroxidation, and synergistically induces cuproptosis/ferroptosis‐like death.

Kinsenoside Targets IDH1 to Restore Microglial Immune‐Metabolic Homeostasis for Alzheimer's Disease Therapy

Advanced Science, EarlyView.
Dysregulated TCA cycle contributes to Alzheimer's disease (AD) pathogenesis. Here, we show that microglial isocitrate dehydrogenase 1 (IDH1) is a critical driver. Elevated IDH1 disrupts citrate metabolism and mitochondrial function, exacerbating AD pathology.
