S100A14 in Tumor‐Derived EVs Targets PIAS3 to Reprogram Astrocytes and Induce Immunosuppressive Microenvironment Promoting Brain Metastasis and Germacrone Reversal Effect

open access: yesAdvanced Science, EarlyView.
This study identifies S100A14 in tumor‐derived exosomes as a key driver of brain metastasis. S100A14 targets PIAS3 in astrocytes, activating STAT3 signaling and promoting immunosuppressive MDSCs recruitment via chemokine secretion. Germacrone, a natural compound, binds S100A14 to disrupt this axis, effectively inhibiting brain metastasis with low ...

ROS Self‐Supply Nanoplatform Based on Fenton Catalyst for Chemodynamic and Immunotherapy: Reprogramming Cold Tumor Into Hot Tumor in Cancer Treatment

open access: yesAdvanced Science, EarlyView.
A multifunctional HA‐conjugated nanoplatform (HA‐PGMC) integrates CuO2, glucose oxidase, and mil‐100 to enable cascade catalytic ROS generation in tumor microenvironments. This self‐supplying ROS strategy induces immunogenic cell death, reprograms “cold” tumors into “hot” ones, and synergizes with PD‐L1 blockade, achieving potent chemodynamic ...

TME/NIR Dual‐Responsive Zinc‐Based Targeted Nanoagonist for Multimodal Amplification of STING‐Mediated Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A multifunctional nanoagonist (cDZ@IP) enables nano‐metabolite–driven multimodal activation of the STING pathway and enhanced immune recognition, achieving potent antitumor immunity and suppressing tumor growth and metastasis. This strategy highlights the rational design of therapeutic metabolites and establishes a new paradigm bridging nanomedicine ...

Radiotherapy Enhances the Oncolytic Efficacy of the Novel Oncolytic Herpesvirus VG161 and Amplifies Its Antitumor Immunity in Breast Cancer

open access: yesAdvanced Science, EarlyView.
RT promotes VG161 replication in BC and its immunostimulatory transgenes expression, which is mediated by the upregulation of GADD34 and HVEM caused by RT. The combination therapy with VG161 and RT increases the abundances of tumor‐infiltrating lymphocytes and elicits potent systemic antitumor immunity, thereby effectively inhibiting local tumors and ...

Induction of CD8+ Cytotoxic T Lymphocytes With MHC Class I Restriction by a Soluble Truncated Oncoprotein [PDF]

open access: yes, 1997
CD8+ cytotoxic T lymphocytes (CTLs), which play a major role in the immunological defense against cancer, recognize endogenously produced peptides in the context of MHC class I molecules.

Epigenetic Silencing of RFX7 Defines a Transcriptional Axis Linking Lactate Metabolism to Immune Checkpoint Therapy in Glioblastoma

open access: yesAdvanced Science, EarlyView.
Glioblastoma (GBM) exhibits RFX7 silencing via promoter hypermethylation, which downregulates PIK3IP1 to activate PI3K/AKT signaling, increase lactate accumulation, and enhance histone H4K12 lactylation. This lactylation upregulates PD‐L1/CSF1 expression and drives the immunosuppressive microenvironment formation.

Tumor‐Intrinsic ARHGEF3 Enhances Antitumor Immunity by Promoting T‐Cell Infiltration and Limiting Myeloid Cell‐Mediated Immunosuppression

open access: yesAdvanced Science, EarlyView.
ARHGEF3 is broadly downregulated across human cancers and correlates with patient prognosis. Tumor‐intrinsic ARHGEF3 activates the RHOA–ROCK–PTEN cascade to inhibit AKT signaling, thereby promoting chemokine‐driven T‐cell infiltration and relieving lipid‐mediated myeloid immunosuppression.

Optimized Ex Vivo Human Liver Slice Culture Maintains Extended Viability and Function for Hepatotoxicity Testing

open access: yesAdvanced Science, EarlyView.
An optimized ex vivo human liver slice culture system preserves tissue architecture, hepatocyte function, and immune‐stromal complexity for at least five days. By refining slice thickness, oxygenation, air‐liquid interface, and extracellular matrix support, the platform enables human‐relevant hepatotoxicity testing and mechanistic studies, offering a ...

Optimization of B Cell Responses in Human Immune System Mice Through Organoid Based Screening

open access: yesAdvanced Science, EarlyView.
Human immune system (HIS) mice show limited B cell responses to immunization. Using HIS mouse spleen organoids, this study identifies cytokine combinations and innate immune signals that drive human B cell expansion, differentiation, and class‐switch. Applying these signals in vivo through temporal separation enables antigen‐specific IgG responses and ...
