Multi‐Bioinspired MOF Delivery Systems from Microfluidics for Tumor Multimodal Therapy

Advanced Science, Journal Year: 2023, Volume and Issue: 10(33)

Published: Oct. 18, 2023

Metal-organic framework (MOF)-based drug delivery systems have demonstrated values in oncotherapy. Current research endeavors are centralized on the functionality enrichment of featured MOF materials with designed versatility for synergistic multimodal treatments. Here, inspired by multifarious biological functions including ferroptosis pattern, porphyrins, and cancer cell membrane (CCM) camouflage technique, novel multi-biomimetic nanocarriers from microfluidics prepared.

Cold and hot tumors: from molecular mechanisms to targeted therapy

Signal Transduction and Targeted Therapy, Journal Year: 2024, Volume and Issue: 9(1)

Published: Oct. 18, 2024

Immunotherapy has made significant strides in cancer treatment, particularly through immune checkpoint blockade (ICB), which shown notable clinical benefits across various tumor types. Despite the transformative impact of ICB treatment therapy, only a minority patients exhibit positive response to it. In with solid tumors, those who respond well typically demonstrate an active profile referred as "hot" (immune-inflamed) phenotype. On other hand, non-responsive may distinct "cold" (immune-desert) phenotype, differing from features tumors. Additionally, there is more nuanced "excluded" positioned between and categories, known type. Effective differentiation understanding intrinsic factors, characteristics, TME, external factors are critical for predicting results. It widely accepted that therapy exerts profound effect on limited efficacy against or "altered" necessitating combinations therapeutic modalities enhance cell infiltration into tissue convert tumors ones. Therefore, aligning traits this review systematically delineates respective influencing extensively discusses varied approaches drug targets based assess efficacy.

Programmed Targeting Pyruvate Metabolism Therapy Amplified Single‐Atom Nanozyme‐Activated Pyroptosis for Immunotherapy

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(24)

Published: Feb. 7, 2024

Abstract Increasing cellular immunogenicity and reshaping the immune tumor microenvironment (TME) are crucial for antitumor immunotherapy. Herein, this work develops a novel single‐atom nanozyme pyroptosis initiator: UK5099 pyruvate oxidase (POx)‐co‐loaded Cu‐NS (Cu‐NS@UK@POx), that not only trigger through cascade biocatalysis to boost of cells, but also remodel immunosuppressive TME by targeting metabolism. By replacing N with weakly electronegative S, original spatial symmetry Cu‐N 4 electron distribution is changed enzyme‐catalyzed process effectively regulated. Compared spatially symmetric nanozymes (Cu‐N SA), S‐doped asymmetric (Cu‐NS SA) exhibit stronger activities, including peroxidase (POD), nicotinamide adenine dinucleotide (NADH) (NOx), L ‐cysteine (LCO), glutathione (GSHOx), which can cause enough reactive oxygen species (ROS) storms pyroptosis. Moreover, synergistic effect SA, UK5099, POx target metabolism, improves increases degree This study provides two‐pronged treatment strategy significantly activate immunotherapy effects via ROS storms, NADH/glutathione/ consumption, oxidation, lactic acid (LA)/ATP depletion, triggering regulating broad vision expanding
