TP53 Loss Elevates NF‐κB‐IFN‐β‐MHC‐Ia Signaling to Promote NK Cell Resistance in Osteosarcoma

Advanced Science, EarlyView.
TP53 loss in a transforming or osteosarcoma cell promotes cytosolic DNA accumulation, activating NF‐κB‐dependent IFN‐β production. Autocrine IFN‐β signaling increases cell‐surface HLA‐Ia expression, strengthens inhibitory KIR signaling in natural killer cells, and thereby enables the affected cell to evade NK cell‐mediated cytotoxicity.

Spatial Transcriptomics Reveals a T Cell‐Mediated Microglial Activation Axis of Immune Checkpoint Inhibition‐Related Adverse Events in the Brain

Advanced Science, EarlyView.
Immune checkpoint inhibition (ICI) reshapes the hippocampal neuroimmune niche. Spatial transcriptomic profiling and human brain histological analyses identify neuroinflammation and altered neuronal and glial programs. Notably, T cell depletion prevents ICI‐driven microglial activation, establishing the T cell–microglia crosstalk axis as a driving ...

DDX21 Enhances Radiosensitivity in Head and Neck Squamous Cell Carcinoma by Suppressing MK2‐Mediated DNA Damage Response

Advanced Science, EarlyView.
DDX21 suppresses MK2 activation by directly inhibiting Thr334 phosphorylation in a p38‐independent manner, thereby impairing DNA damage response. Clinically, patients with well‐differentiated tumors exhibiting high DDX21 expression are more likely to benefit from adjuvant radiotherapy, whereas those with low DDX21 levels are predisposed to ...

Magnetically Guided Macrophage Immunobots Coordinate Iron‐Metabolic Cascades and Immunogenic Ferroptosis for Tumor Immunotherapy

Advanced Science, EarlyView.
Magnetically guided macrophage immunobots integrate active tumor targeting with immunometabolic therapy. After systemic administration, magnetic actuation enhances immunobot retention and tumor penetration, while LPS‐functionalized FePt microrollers sustain M1‐like polarization through inflammatory and iron‐amplified oxidative signaling and trigger ...

Spatial Au+ Mapping Reveals a Self‐Amplifying Anti‐Tumor Immunity Loop Driven by Au(I) Complexes

Advanced Science, EarlyView.
The first report of spatial Au+ mapping of a representative gold complex (Au9). Macrophages, DCs, and tumor cells ranked as the top three in Au+ enrichment after Au9 treatment. Interestingly, Au9 treatment could induce ferroptosis and suppress cellular cholesterol, further eliciting a self‐amplifying anti‐tumor immunity loop.

Granzyme B PET Imaging Reveals Lgmn+ Macrophage‐Mediated Immune Evasion and Guides Immunotherapy in EGFR‐TKI‐Resistant NSCLC

Advanced Science, EarlyView.
Graphical illustration of 68Ga‐GZB PET/CT imaging reveals immune dynamics post‐EGFR‐TKI resistance in NSCLC; Lgmn+ macrophages‐derived Lgmn‐containing extracellular vesicles inhibit glycolysis, induce CD8+ T cell exhaustion, and targeting Lgmn restores immunotherapy sensitivity.

Asymmetric Structure‐Driven Functional Synergy: A Multistimuli‐Activated Janus Nanomotor for Self‐Amplifying NO Cascade Therapy

Advanced Science, EarlyView.
The Janus nanomotors leverage an “asymmetric structure‐driven functional synergy” strategy to orchestrate spatiotemporally coordinated catalytic functions, in situ self‐amplifying NO generation, and deep tumor penetration, thereby enabling controllable, sustained, and uniform NO generation within the tumor microenvironment.

Assembled Hyaluronic Acid Therapeutics for Targeting M1 Macrophages and Regulating Immune Homeostasis for Ulcerative Colitis Treatment

Advanced Science, EarlyView.
An orally administered, drug‐free hyaluronic acid nanoassembly, uhNAs‐OA, accumulates in the inflamed colon and is preferentially internalized by M1‐like macrophages via HA‐CD44 interactions. uhNAs‐OA scavenges excess ROS, suppresses NF‐κB signaling and remodels the colonic immune landscape, resulting in robust therapeutic efficacy in acute, chronic ...

Integrated Multi‐Omics Reveals Cellular States and Microenvironmental Remodeling in Coexisting DCIS and IDC

Advanced Science, EarlyView.
Coexisting DCIS and IDC samples are profiled using spatial transcriptomics, single‐cell RNA sequencing, and single‐cell DNA sequencing. Integrative multi‐omics analysis reveals distinct malignant epithelial and microenvironmental features between DCIS and IDC, which are further validated using Xenium and multiplex immunohistochemistry.

Platycodon grandiflorus–Derived Nanovesicles Sensitize Gastric Cancer to T Cell Killing via Ferroptosis‐Driven Membrane Mechanical Remodeling

Advanced Science, EarlyView.
Plant‐derived nanovesicles from Platycodon grandiflorus act as bioactive lipid delivery platforms that transport γ‐linolenic acid into gastric cancer cells. This lipid cargo promotes ferroptotic lipid peroxidation, remodels membrane mechanics, and increases tumor‐cell susceptibility to cytotoxic T‐cell attack.
