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

open access: yesAdvanced 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 ...

Selective Targeting of Tip Endothelial Cells as a Therapeutic Strategy for Tumor Angiogenesis

open access: yesAdvanced Science, EarlyView.
Doppel protein is selectively expressed in tip endothelial cells within the tumor vasculature, where it promotes tip cell motility and stabilizes the tip cell phenotype. Targeting Doppel with monoclonal antibodies disrupts this stabilization, impairs angiogenic sprouting, and reduces tumor angiogenesis, offering a selective and druggable switch for ...

ITGB1 Regulates Triple‐Negative Breast Cancer Development by Modulating the Tumor Microenvironment

open access: yesAdvanced Science, EarlyView.
ABSTRACT Tumorigenesis and metastasis are frequently attributed to the intricate interplay between cancer cells and the tumor microenvironment (TME). Comprehending the mechanisms and key regulators of cancer‐immune crosstalk in the TME is imperative for developing efficacious immunotherapy.

Endocytic Control of Cell‐Autonomous and Non‐Cell‐Autonomous Functions of p53

open access: yesAdvanced Science, EarlyView.
NUMB Ex3‐containing isoforms localize to the plasma membrane, where they recruit p53 through SNX9 and direct it to multivesicular bodies and exosomes. Exported p53 is taken up by neighboring cells and activates nuclear programs, revealing an intercellular, exosome‐based pathway that might help establish a tumor‐suppressive microenvironment.

Allogeneic Immune Cell Perfusion Inhibits the Growth of Vascularized 3D In Vitro Tumor Models, Induces Vascular Regression and Desmoplasia, but Promotes Tumor Cell Invasion

open access: yesAdvanced Science, EarlyView.
This study presents a vascularized 3D tumor model to investigate immune–stromal–tumor interactions under allogeneic PBMC perfusion. While immune cells induced tumor shrinkage, they also promoted vascular regression, stromal activation, and cancer cell invasion.
