Lithium‐Doped Hydroxyapatite Nanowires Rejuvenate Senescent Macrophages Via the Lysosome‐Dependent Ferroptosis Axis to Promote Aged Bone Regeneration

Advanced Science, EarlyView.
Li‐nHAP+GelMA promotes mandibular bone regeneration in aged mice by remodeling the senescent immune microenvironment. Local delivery of Li‐nHAP restores lysosomal homeostasis in senescent macrophages, reduces intracellular labile Fe2+ accumulation, ROS production, and lipid peroxidation, thereby suppressing macrophage ferroptosis and senescence ...

Engineered Chiral Probiotics Ameliorate MASH via Gut–Liver Axis

Advanced Science, EarlyView.
A chiral gold nanozyme was coated onto the gut commensal bacterium Faecalibacterium duncaniae (F. duncaniae) to create an engineered probiotic. In mouse models of MASH, this orally administered living therapeutic protected the bacterium against oxidative stress, enhanced its gut colonization, reversed steatosis, inflammation, and fibrosis, and improved

Plasma Membrane Lipid Asymmetry Dynamically Regulates Passive Diffusion

Advanced Science, EarlyView.
Passive diffusion enables hydrophobic molecules to cross the plasma membrane and exert their biological functions. This study demonstrates that plasma membrane lipid asymmetry, dynamically regulated by lipid scrambling, determines membrane permeability to lipophilic molecules and thereby modulates their cellular activities.

BRCA1 Mutation‐Recognizing Tetrahedral Framework Nucleic Acid Nanoplatform Enables Coordinated PARP/WEE1 Inhibition and STING‐Associated Antitumor Immunity in Ovarian Cancer

Advanced Science, EarlyView.
BRCA1 mutation‐responsive FBOA‐tFNA selectively recognizes mutant transcripts and coordinates reduction‐responsive intracellular delivery of olaparib and adavosertib, amplifying DNA damage and weakening G2/M checkpoint protection. These effects are accompanied by STING‐associated immune activation and stronger antitumor immunity, while sequential anti ...

pH‐Responsive Nanoplatform‐Mediated Lipid Hijacking and Metabolic Collapse for Synergistic Starvation‐Immunotherapy

Advanced Science, EarlyView.
A pH‐responsive ZIF‐8/2‐DG@Cu‐TA nanoplatform orchestrates multifaceted metabolic disruption for synergistic starvation‐immunotherapy. Acid‐triggered 2‐DG release blocks glycolysis, while Zn2+ overload induces mitochondrial dysfunction. Concurrently, Cx43‐mediated gap junctions redirect lipid droplets from tumor cells to cancer‐associated fibroblasts ...

Lactate Homeostasis Disruption Potentiates TACE‐Immunotherapy in Hepatocellular Carcinoma

Advanced Science, EarlyView.
Lactate homeostasis is disrupted through spatially coordinated extracellular neutralization and intracellular acidification, triggering calcium overload, mitochondrial dysfunction, and immunogenic cell death. This metabolic reprogramming alleviates the immunosuppressive tumor microenvironment and enhances immune checkpoint blockade, providing a ...

A Bioengineered Mitochondrial Respiration‐Mimetic Copper‐Based Metal‐Organic Framework Reprogramming Oxidative Phosphorylation to Enhance Tumor Cuproptosis

Advanced Science, EarlyView.
A bioengineered mitochondrial respiration‐mimetic nanoplatform (TC@OMG) renews tumor mitochondrial metabolism to enhance cuproptosis. TC@OMG integrates a copper‐based metal‐organic framework co‐loaded with glucose oxidase and a lactate dehydrogenase inhibitor, and is cloaked with a hybrid membrane derived from tumor cells and plant thylakoids, enabling

A Celastrol–Platinum(IV) Nanoprodrug Couples Ferroptosis With Caspase‐Independent Pyroptosis to Enhance Anti‐PD‐1 Therapy in Colorectal Cancer

Advanced Science, EarlyView.
CPAN integrates celastrol‐driven oxidative stress with Pt(IV)‐induced DNA damage to couple ferroptosis with caspase‐independent pyroptosis. Celastrol disrupts the GSH/GPX4 axis and promotes lipid peroxidation, while Pt(IV)‐associated PARP/PARylation signaling facilitates full‐length GSDME oligomerization.

Expression profile of efflux pumps during the intracellular life of Shigella

, 2016
In several bacterial pathogens, efflux pumps, besides exporting antimicrobial agents, play a role in bacterial pathogenicity. Shigella, the causative agent of bacillary dysentery, shares a high homology with its commensal ancestor Escherichia coli but ...

LepR‐Lineage Cells Represent the Main Target of the Nociceptive CGRP Pathway in White Adipose Tissue Browning

Advanced Science, EarlyView.
Regulation of WAT Browning and UCP1 Expression in LepR‐MSCs of Inguinal WAT by Nociceptive CGRP and Sympathetic Nervous System (SNS) Noradrenaline (NE). ABSTRACT Sympathetic innervation regulates white adipose tissue (WAT) browning; however, the roles of nociceptive neurons and their associated target cells remain unknown.
