Engineered Small Extracellular Vesicles Targeting Tumor‐Associated Endothelial Cells to Effectively Remodel the Glioma Microenvironment

Advanced Science, EarlyView.
This study developed a novel drug delivery platform that overcomes the blood‐brain barrier in glioblastoma. By fusing IGFBP7 with small extracellular vesicles, the platform specifically targets tumor vasculature. It effectively delivers temozolomide, suppressing tumor growth at low doses.

Mineralized Cryogel/Hydrogel Constructs to Recapitulate Early Breast Cancer Bone Metastasis In Vitro

Advanced Science, EarlyView.
A new biphasic in vitro cryogel/hydrogel model of early breast cancer bone metastasis provides precise control over microenvironmental cues and microscopic access to the spatiotemporal cancer cell distribution. Deposited bone‐like mineral is observed to strongly impede the effects of biomolecular signals, as evidenced by both colonization profiles and ...

Discovery of a First‐in‐Class Covalent Allosteric SHP1 Inhibitor with Immunotherapeutic Activity

Angewandte Chemie, EarlyView.
A covalent allosteric inhibitor M029 was discovered for SHP1, a novel target for immunotherapy. M029 binds to a cryptic Cys remote from the active site, exhibits robust target engagement, and blocks tumor progression by stimulating antitumor immune response.

Gut Microbiota‐Non‐Coding RNA Axis in Immune Modulation and Disease: From Mechanisms to Clinical Translation

Advanced Science, EarlyView.
ABSTRACT Immune homeostasis is indispensable for preserving organismal integrity, orchestrated through complex molecular networks encompassing immune cell dynamics, microbial cues, and epigenetic regulation. Among these, the gut microbiota‐non‐coding RNA (ncRNA) axis has recently garnered substantial attention as a multifaceted modulator of host ...

T Cell Exhaustion in Cancer Immunotherapy: Heterogeneity, Mechanisms, and Therapeutic Opportunities

Advanced Science, EarlyView.
T cell exhaustion limits immunotherapy efficacy. This article delineates its progression from stem‐like to terminally exhausted states, governed by persistent antigen, transcription factors, epigenetics, and metabolism. It maps the exhaustion landscape in the TME and proposes integrated reversal strategies, providing a translational roadmap to overcome

Effects of rotor blade modulation on GNSS anti-jamming algorithms [PDF]

, 2014
In hostile environment, Global Navigation Satellite System (GNSS) could be disturbed by intentional jamming. Many adaptive algorithms have been developed to deal with these threats, among which use of antenna arrays is one of the most efficient. However,

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi

Advanced Science, EarlyView.
Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

Intelligent Anti-Jamming Based on Deep Reinforcement Learning and Transfer Learning

IEEE Transactions on Vehicular Technology
One of the security issues in a wireless network is jamming attacks, where the jammer causes congestion and significant decrement in the network throughput by obstructing channels and disrupting user signals.
