A Microbiota‐ and IL‐15‐Dependent Innate‐Like B Cell Progenitor Expressing E4BP4

Advanced Science, EarlyView.
This work identifies CD3.NKp46.CD19.NK1.1. NK‐B cells enriched in PDK1‐deficient yet present in wild‐type bone marrow. IL‐15 (via CD122) and TLR9‐microbiota signaling maintain their E4BP4 expression. These cells demonstrate innate immunity, preferentially differentiate into B cells, and unveil a novel microbiota‐ and IL‐15‐dependent regulatory pathway ...

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

Advanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...

Microglial Fkbp5 Impairs Post‐Stroke Vascular Integrity and Regeneration by Promoting Yap1‐Mediated Glycolysis and Oxidative Phosphorylation

Advanced Science, EarlyView.
A post‐stroke perivascular niche of microglia characterized by low expression of M2 markers and elevated glycolysis, oxidative phosphorylation (OXPHOS), and phagocytic activity is identified, which is termed stroke‐activated vascular‐associated microglia (stroke‐VAM).

Efferocytosis‐Driven Polyamine Metabolism in Macrophages Enhances Cancer Stem Cell Enrichment after Chemotherapy in Ovarian Cancer

Advanced Science, EarlyView.
Chemotherapy‐induced efferocytosis drives ovarian cancer stem cell enrichment. By engulfing apoptotic cancer cells, macrophages upregulate ODC1 and produce putrescine, which elevates osteopontin (OPN) expression. Secreted OPN then activates the CD44 receptor on cancer cells, promoting stemness and chemoresistance.

A Rationally Engineered Spleen‐Tropic One‐Component Lipid‐mRNA Complex (OncoLRC) for Cancer Vaccines

Advanced Science, EarlyView.
OncoLRC, a one‐component lipid‐mRNA complex, enables efficient spleen‐targeted delivery at an exceptionally low lipid‐to‐mRNA mass ratio (1.5:1), robustly activates immune responses, inhibits tumor growth, and synergizes with checkpoint blockade, presenting a next‐generation platform for mRNA vaccines.
