Thioredoxin‐2 Alleviates Osteoporosis by Restraining FOXO3a Nuclear Translocation

Advanced Science, EarlyView.
Endothelial TRX2 preserves bone homeostasis by retaining FOXO3a at mitochondria and limiting TRAIL production. Loss of TRX2 or oxidative stress releases FOXO3a for nuclear translocation, increasing endothelial TRAIL secretion and driving osteoclast formation and bone loss.

A Fish MDA5 Integrates Canonical RIG‐I and MDA5 Ligand Recognition

Advanced Science, EarlyView.
These results show that the large yellow croaker lacks RIG‐I, yet its MDA5 senses both 5′ppp‐dsRNA and long dsRNA. A flexible RNA‐capping loop in the MDA5 C‐terminal domain enables two ligand‐binding modes. This dual recognition signals through MAVS–STING–TBK1/IRF3 and induces type I interferons, revealing unexpected plasticity in vertebrate antiviral ...

Large Oncosomes Induce Pro‐Metastatic Stromal‐Myeloid Reprogramming

Advanced Science, EarlyView.
Large oncosomes systemically reprogram bone marrow mesenchymal stem cells through innate nucleic acid sensing, driving inflammatory and immunosuppressive remodeling that supports a metastasis‐permissive bone marrow environment, revealing a novel tumor‐host communication axis in cancer. ABSTRACT Bone metastasis can be facilitated by systemic remodeling,

Transgenesis and humanization of murine antibodies.

, 2009
International audienceThe properties of monoclonal antibodies explain why they are such a successful class of therapeutic molecules. However, pionneered initial antibodies were of murine origin and triggered an immune response which limited the ...

In Vivo CRISPR Screen Identifies RPS19 as an Immunotherapy Target in Hepatocellular Carcinoma

Advanced Science, EarlyView.
By employing in vivo CRISPR functional screening, we identify ribosomal protein RPS19 as a pivotal mediator driving immune evasion in hepatocellular carcinoma, wherein tumor‑released RPS19 binds C5aR1 on tumor‑associated macrophages to initiate downstream immunosuppressive signaling; SP94‑peptide‑modified SNPSS nanoparticles deliver Cas9/sgRPS19 ...

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

Combined Immune‐Peptide Nanofiber with HSP70/AKT/mTOR Axis Blockade Enhances Photothermal Immunotherapy, Inhibiting Tumor Growth and Recurrence

Advanced Science, EarlyView.
A carrier‐free peptide‐guided PSP@IR‐CF3 nanofiber system integrates PD‐L1 targeting and photothermal immunotherapy for enhanced cancer treatment. By revealing PTIT‐induced activation of the HSP70/AKT/mTOR pathway and incorporating mTOR inhibition, this strategy effectively overcomes therapeutic resistance and prevents tumor recurrence, providing a ...

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.

Phase‐Programmed Microneedles Enable Sequential Hydrogen and Quercetin Release for Scar‐Reduced Regeneration of Burn Wounds

Advanced Science, EarlyView.
A phase‐programmed microneedle patch, comprising a poly (lactic‐co‐glycolic acid) (PLGA) shell and a sulfobutylether‐β‐cyclodextrin (SBECD) core, is designed for sequential hydrogen and quercetin release for scar‐reduced regeneration of burn wounds. ABSTRACT Burn wounds complicated by bacterial infection and fibrotic scarring remain a major clinical ...

Loss of Lepr in Fibroblasts Drives Tumor Development by Promoting Macrophage Infiltration

Advanced Science, EarlyView.
TNFα and TGFβ signaling reprograms Lepr+ fibroblasts toward a LeprnegMmphigh inflammatory CAF (iCAF) state, with downregulation of the Tcf21‐Lepr axis contributing to this transition. Lepr loss induces Csf3, which contributes to the enhanced macrophage‐recruiting capacity of these iCAFs, thereby promoting tumor development. Thus, inflammatory signaling
