Alternative Pathway for Methyl Supply through the Coupling of SHMT1 and PEMT to Maintain Astrocytic Homeostasis in Parkinson's Disease

open access: yesAdvanced Science, EarlyView.
In Parkinson's disease, SHMT1 downregulation disrupts its interaction with PEMT in astrocytes, reducing SAM levels. This leads to H3K4me1 hypomethylation and decreased Slc1a2/Glul expression, ultimately exacerbating neuroexcitotoxicity and dopaminergic neuron loss.

Caspase‐3/GSDME‐Mediated Trophoblast Pyroptosis and Reciprocal Macrophage Polarization Contribute to Inflammation in Early‐Onset Preeclampsia

open access: yesAdvanced Science, EarlyView.
In trophoblast cells, T/S (TNFα + SM164) activated caspase‐3, which cleaved GSDME to switch apoptosis to pyroptosis, causing cell swelling, membrane rupture, and release of LDH, HMGB1, IL‐1β and IL‐18. These cytokines induced pro‐inflammatory macrophage polarization, which in turn reinforced pyroptotic signaling in trophoblasts, amplifying systemic ...

SETDB2 Mitigates Podocyte Dysfunction in Diabetic Kidney Disease Through Epigenetic Silencing of SMAD3

open access: yesAdvanced Science, EarlyView.
SETDB2 epigenetically represses Smad3 transcription by increasing H3K9me3 enrichment at its promoter, thereby mitigating podocyte dysfunction in DKD. The transcription factor TCF21 binds directly to the Setdb2 promoter and enhances its expression in podocytes. Abstract Podocyte dysfunction represents both an early pathological hallmark and a key driver

RPS3‐Enriched Extracellular Vesicles Mediate Liver‐Spinal Cord Inter‐Organ Communication

open access: yesAdvanced Science, EarlyView.
Spinal cord injury activates the liver to send extracellular vesicles loaded with RPS3 protein to the lesion site. These vesicles are taken up by neural stem cells and astrocytes, triggering NF‐κB signaling, impairing the regeneration of neurons and myelin, and promotes harmful inflammation, ultimately hindering recovery.

IgG‐Bridging–Seeded Synergistic Aggregation of SARS‐CoV‐2 Spikes Underlies Potent Neutralization by a Low‐Affinity Antibody

open access: yesAdvanced Science, EarlyView.
Low‐affinity antibodies are frequently disregarded in discovery pipelines. This work reports P5‐1C8, a Class 1 SARS‐CoV‐2 antibody with weak trimer binding (KD‐to‐IC50 > 3700‐fold) yet potent neutralization of Omicron JN.1. Structural, biophysical, functional, and coarse‐grained simulations collectively demonstrate that transient inter‐spike IgG ...
