Postsynaptic Complexin Mediates Constitutive Exocytosis of Nicotinic Acetylcholine Receptor

open access: yesAdvanced Science, EarlyView.
Beyond its established presynaptic role, complexin is identified as a postsynaptic regulator of neurotransmitter receptor trafficking. By promoting constitutive and activity‐dependent exocytosis of nicotinic acetylcholine receptors, complexin controls spontaneous synaptic signaling at the C.

Redox metabolism in cell senescence: focusing on contributions from the metabolomic field

open access: yesFrontiers in Molecular Biosciences
Cell senescence is triggered by stressful stimuli, including telomere attrition, genotoxic agents, and strong mitogenic signals. This state is characterized by proliferation arrest and acquisition of a senescence-associated secretory phenotype. Senescent

Leveraging Macrophage Metabolic Reprogramming for Enhanced Anti‐Tumor Immunity

open access: yesAdvanced Science, EarlyView.
Tumor‐associated macrophages (TAMs) are key regulators of the tumor microenvironment (TME), with their metabolic states playing a critical role in tumor progression or regression. This review summarizes current understanding of TAM metabolic plasticity alongside cutting‐edge bioengineering innovations, outlining a roadmap for transforming the ...

Engineering Approaches to Modify Immunomodulatory Functions of Mesenchymal Stromal Cells (MSCs): Tissue Regeneration and Clinical Application

open access: yesAdvanced Science, EarlyView.
Mesenchymal stromal cells (MSCs) show promise for treating immune‐related disorders through immunomodulation and tissue regeneration. This review gives a brief overview of current clinical approval of MSC therapies. It also discussed how bioengineering, including genetic modification, biomaterial delivery, extracellular vesicles, and iPSC‐derived MSCs,

Dynamic Shifts in ER–Plasma Membrane Junctions Signaling Define Pro‐Metastatic N‐Glycosylation and Predict Prostate Cancer Progression

open access: yesAdvanced Science, EarlyView.
Prostate cancer remains a leading cause of male cancer death, yet screening cannot reliably identify aggressive disease, underscoring the need for tissue biomarkers. It is shown that primary tumors increase ER–plasma membrane junction signaling via STIM1/ORP5, whereas metastasis features their loss, Golgi dispersal, and rapid conversion of high‐mannose

Hepatoma‐Derived Growth Factor Coordinates STAT3 Pathway and Exosome‐Mediated Intrahepatic Crosstalk to Control Hepatic Steatosis and MASLD

open access: yesAdvanced Science, EarlyView.
Hepatic HDGF as a key mediator in coordinating hepatic steatosis and intrahepatic crosstalk in MASLD. Activation of HDGF facilitates its interaction with both STAT3 and S6K1, driving the S6K1‐dependent STAT3 phosphorylation and subsequently enhancing hepatic lipogenesis.

Injectable Porous Microspheres Loaded With Biomimetic Preconditioned Bone Marrow Mesenchymal Stem Cell‐Derived Exosomes for Vascularized Bone Regeneration

open access: yesAdvanced Science, EarlyView.
Schematic illustration of injectable PDA‐modified GelMA microspheres loaded with BioPre‐Exos for vascularized bone regeneration. ABSTRACT Critical‐sized bone defects remain a highly challenging clinical problem due to insufficient intrinsic self‐healing capacity.

SETD1A Regulates Glycolysis and Senescence of Nucleus Pulposus Cells via H3K4me3–HELZ2/PPARα‐HIF1α Axis to Drive Intervertebral Disc Degeneration

open access: yesAdvanced Science, EarlyView.
SETD1A is a key epigenetic regulator in NPCs during IDD. In normal NPCs, it sustains H3K4me3–HELZ2/PPARα–HIF1α signaling to maintain glycolytic energy metabolism and proliferation. In degenerated NPCs, reduced SETD1A disrupts this axis, impairing glycolysis and accelerating senescence, highlighting a promising therapeutic target for IDD.
