Programmable Encapsulation Enables On‐Demand Proliferation of Therapeutic Bacteria for Potent Cancer Immunotherapy

Advanced Science, EarlyView.
A programmable encapsulation technology is developed to reduce bacterial immunogenicity and proliferation after systemic administration. The cross‐linked polymer networks around individual bacteria enable immunogenic shielding and permit selective proliferation in tumors, allowing the bacteria to convert tumor‐accumulated ammonia into L‐arginine and ...

Immediate Growth Control in Response to Boiling Histotripsy is Prognostic for Intratumoral Immune Activation

Advanced Science, EarlyView.
Boiling Histrotripsy (BH), a mechanical form of focused ultrasound (FUS), allows for non‐invasive and non‐ionizing tissue destruction. Utilizing a BH treatment protocol that yielded bifurcating primary tumor growth responses, we found that immediate BH‐induced tumor growth control identifies tumors with acute reductions in antigen‐presenting cells (APC)

Acute and subacute (28 days) toxicity, hemolytic and cytotoxic effect of Artocarpus heterophyllus seed extracts

Toxicology Reports, 2019
Background: Plants and their parts are a part of life in many Brazilian communities, as observed in the jackfruit. The jackfruit seeds are consumed, usually, as roasted, boiled, steamed, and are eaten as a snack.

Versatile Co‐Engineering of Immunogenic Cell Death‐Primed Dead Tumor Cell Bodies With Tumor‐Activated MnO2 for cGAS‐STING‐Potentiated Personalized Immunotherapy

Advanced Science, EarlyView.
DTBEI@CS@MnO2, fabricated via modular electrostatic co‐engineering and photothermal/photodynamic immunogenic cell death, specifically responds to the acidic and GSH‐rich tumor microenvironment. This triggers the release of DTBEI that provides tumor antigens, DNA, and DAMPs, as well as the generation of Mn2+, thereby synergistically potentiating cGAS ...

Inclusion of ΑVβ3 integrin into extracellular vesicles in a caveolin-1 tyrosine-14- phosphorylation dependent manner and subsequent transfer to recipient melanoma cells promotes migration, invasion and metastasis

Cell Communication and Signaling
Caveolin-1 (CAV1) is a membrane protein that promotes migration, invasion and metastasis of cancer cells when phosphorylated on tyrosine-14 (Y14) by a cell intrinsic mechanism involving the activation of a novel Rab5-Rac1 signaling axis.

Plant Virus Immunotherapy for HPV‐Associated Oropharyngeal Squamous Cell Carcinoma

Advanced NanoBiomed Research, EarlyView.
Cowpea mosaic virus (CPMV) nanoparticles are safe and potent cancer immunotherapy candidates with strong immunomodulatory activity. CPMV activates innate immunity, which in turn drives adaptive immune responses and promotes durable, systemic antitumor effects.
