NS1‐Induced PARP1 Phase Transitions Prolongs Host Transcriptional Pausing to Promote Influenza A Virus Replication

Advanced Science, EarlyView.
After IAV infection, NS1 induces PARP1 phase transition, reducing molecular mobility in condensates, prolonging host transcriptional pause, aiding RdRp cap snatching, and promoting viral transcription. ABSTRACT Influenza A virus (IAV) commandeers host transcriptional machinery to replicate, but mechanisms remain elusive.

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

Advanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

ACAT1‐Mediated SP1‐K694 Lactylation Promotes M1 Macrophage Polarization via TREM1 Transcription in COPD

Advanced Science, EarlyView.
Upon cigarette smoke exposure(CSE), LDHA expression is increased in lung macrophages, promoting the conversion of pyruvate to lactate and elevating the lactylation level of SP1 at the K694 site. This, in turn, enhances SP1 enrichment at the TREM1 promoter, increases TREM1 expression, promoted M1 macrophage polarization, and triggers the secretion of ...

LAPTM5 Downregulation‐Driven VAMP8 Phosphorylation Impairs Autophagosome‐Lysosome Fusion and Aggravates Septic Acute Lung Injury

Advanced Science, EarlyView.
LAPTM5 functions as a critical molecular scaffold bridging PGAM5 and VAMP to facilitate PGAM5‐mediated dephosphorylation of VAMP8. This cascade promotes autophagosome‐lysosome fusion, restores impaired autophagic flux, and clears damaged mitochondria, thereby mitigating cellular oxidative stress and systemic inflammation.

Transformer‐Based PET/CT Fusion Enables Preoperative Prediction and Prognostic Stratification of Spread Through Air Spaces in Lung Adenocarcinoma

Advanced Science, EarlyView.
An eight‐stream 2.5D Transformer integrates complementary PET metabolic and CT morphologic information to estimate spread‐through‐air‐spaces risk before surgery in lung adenocarcinoma. The model generalizes across independent centers, while its continuous risk score independently stratifies progression‐free survival, supporting further prospective ...

scH16S‐Seq Maps Klebsiella pneumoniae‐Associated Myeloid States and Reveals a CD38–NAD Immunometabolic Axis That Impairs Lysosomal Acidification in Sepsis

Advanced Science, EarlyView.
Single‐cell host–bacterial 16S co‐sequencing (scH16S‐seq) integrates cell‐associated bacterial 16S‐derived signals with host transcriptomes to resolve bacterial signal‐enriched myeloid states in Klebsiella pneumoniae sepsis. Complementary pharmacological and genetic analyses define a CD38–NAD immunometabolic axis connecting mitochondrial bioenergetic ...
