3D Soft Hydrogels Induce Human Mesenchymal Stem Cells “Deep” Quiescence

Advanced Healthcare Materials, EarlyView.
Three‐dimensional soft hydrogels mimicking the bone marrow niche induce deep quiescence in human mesenchymal stem cells. Unlike 2D culture, 3D matrices halt proliferation, regulate cell‐cycle and quiescence markers, and downregulate mTORC1 signaling, preserving stem cell phenotype and therapeutic potential ex vivo.

Mitochondria‐Specific Protein Delivery by Protease‐Triggered Release in Plants with Single‐Walled Carbon Nanotubes

Advanced Materials Technologies, EarlyView.
Polymer‐coated carbon nanotubes were engineered as protease‐responsive nanocarriers for protein delivery in intact plants. GFP cargo can be released by cytosolic phytaspase cleavage and subsequently targeted to mitochondria via an N‐terminal sequence, enabling controlled intracellular protein delivery without tissue damage and demonstrating stable ...

Shigella type-III secretion system effectors counteract the induction of host inflammation and cell death

The EMBO Journal
Many enteric bacterial pathogens deliver virulence effectors to counteract host innate immune responses, such as inflammation and cell death, and colonize the intestinal epithelium.

CypD Dependent mPTP Opening Is Crucial for Oxidized Mitochondrial DNA Release in Ferroptosis

Advanced Science, EarlyView.
Ferroptosis is driven by mitochondrial permeability transition pore (mPTP) opening, which induces mitochondrial swelling and releases oxidized mitochondrial DNA. The released mtDNA activates cGAS–STING signaling, promotes ferritinophagy, and amplifies ferroptotic cell death. Disruption of mtDNA repair sensitizes tumors to ferroptosis in vivo, revealing

A bacterial network of T3SS effectors counteracts host pro-inflammatory responses and cell death to promote infection

The EMBO Journal
Innate immune signalling and cell death pathways are highly interconnected processes involving receptor-interacting protein kinases (RIPKs) as mediators of potent anti-microbial responses.

DRD2 Deficiency Underlies Pituitary Adenoma Dependent on Escherichia coli Translocation from the Gut

Advanced Science, EarlyView.
Dopamine receptor D2 (DRD2) deficiency disrupts epithelial barrier integrity in both the gut and pituitary gland, facilitating translocation of gut‐derived Escherichia coli into pituitary tissue. Intratumoral E. coli are phagocytosed by microglia, triggering GSDMD‐dependent pyroptosis and HMGB1 release, which subsequently activates MAPK signaling to ...

Astrocyte Enrichment of 3D Cortical Constructs Enhances Brain Repair

Advanced Science, EarlyView.
This study highlights the role of astrocytes in supporting neural progenitor cell survival and differentiation after traumatic brain injury. Astrocytes enhanced neuronal differentiation, improved cell survival in co‐cultures, and promoted integration of microfluidics‐based implants with host tissue following implantation. Additionally, increased axonal
