Glycolytic Enzyme HK2 Phosphorylates nSMase1 to Promote Astrocytic Exosomes Biogenesis Contributing to Acute Ischemic Stroke Injury

Advanced Science, EarlyView.
This study reveals that the glycolytic enzyme HK2 mediates hypoxia‐induced astrocytic exosome biogenesis by directly phosphorylating nSMase1. These astrocytic exosomes impair brain endothelial tight junctions. Astrocyte‐specific knockdown of HK2 reduces exosome release and alleviates brain injury after MCAO.

Hydrogen‐Producing Catalysts Based on Ferredoxin Scaffolds

Advanced Science, EarlyView.
Selected plant‐type ferredoxins that lack their natural [2Fe‐2S] clusters functionally bind a hydrogenase active site cofactor and act as hydrogenases themselves. In combination with photosystem I, the light‐dependent H₂ evolution almost matches the H₂ production rates of the natural system.

Bionic Nanostructures Create Mechanical Signals to Mediate the Composite Structural Bone Regeneration Through Multi‐System Regulation

Advanced Science, EarlyView.
Inspired by the structural and functional characteristics of bone, bionic nanomaterials combined with nanotechnology can more accurately replicate stem cell niches, enabling the design of bone tissue engineering scaffolds with diverse nanoscale properties to promote stem cell migration, proliferation, and differentiation. This precise control over stem

PFKFB2‐Driven Glycolysis Promotes Dendritic Cell Maturation and Exacerbates Acute Lung Injury

Advanced Science, EarlyView.
Paraquat (PQ) or lipopolysaccharide (LPS) exposure activates the HIF‐1α–PFKFB2 pathway, driving glycolysis in dendritic cells (DCs). This metabolic shift enhances DC maturation and immune activation, exacerbating acute lung injury (ALI). This study demonstrates that PFKFB2‐driven glycolytic reprogramming in DCs plays a critical role in the pathogenesis

A Novel Cultivation System for Germ Cell Proliferation and Sustaining Whole Testicular Niche

Advanced Science, EarlyView.
A hydrogel microneedle‐based system enables whole testicular cultivation, supporting spermatogonial proliferation and enhancing spermatogenesis in vitro. This ‘whole testicular spermatogonia pool’ (WTSP) significantly increases spermatid production and fertility potential in mice. This system also promotes spermatogonial expansion in human fetal testes,
