Regulating Tumor Metabolic Reprogramming with Biomimetic Co‐Delivery of Simvastatin and Kynureninase for Immunotherapy

open access: yesAdvanced Science, EarlyView.
After the intravenous injection of biomimetic and pH/ROS‐responsive PTSK@CRM, the nanoparticles can be accumulated in tumors and release Sim and KYNase to inhibit the tumor growth, regulate the metabolism of cholesterol and Kyn, and reverse the immunosuppressive tumor microenvironment.

PARPi Combining Nanoparticle LIN28B siRNA for the Management of Malignant Ascites

open access: yesAdvanced Science, EarlyView.
This study demonstrates that co‐inhibition of LIN28B and PARP using siLin28b/DSSP@lip‐PEG‐FA nanoparticles in combination with the PARP inhibitor BMN673 effectively suppresses the accumulation of malignant ascites associated with advanced cancers.

Biomimetic Organic Nanozyme as Tumor Vaccines for Targeted Suppression of Ammonia‐Induced T Lymphocyte Death to Augment Breast Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
The organic nanozyme IR‐IHpd, which has NIR‐PDT and POD‐like activity, is designed for continuous ROS generation. It is co‐encapsulated with CB‐839 and coated with DC membranes to simultaneously target tumors and T cells. Under NIR irradiation, immunogenic cell death is activated. Concurrently, CB‐839 suppresses ammonia‐induced T lymphocyte death (AITD)

Precision‐Engineered Silver Single‐Atom Carbon Dot Nanozymes for Theranostic Management of Acute Kidney Injury

open access: yesAdvanced Science, EarlyView.
Mitochondria‐targeted silver single‐atom carbon dot (T‐AgSA‐CDs) nanozymes enable dual SOD/GPx‐like ROS scavenging, real‐time imaging, and therapeutic effects for acute kidney injury (AKI). Atomically dispersed Ag sites synergize with carbon dots to restore renal redox hemostasis, protect mitochondrial function, mitigate inflammation, facilitate post ...

Calcium retinoate nanoparticle mediated microglial polarization to regulate inflammatory microenvironment for therapy of neuroinflammatory disease

open access: yesBMEMat, EarlyView.
A nano‐drug based on retinoic acid and calcium is developed, which can be rapily endocytosed by microglia and decomposed into small molecule/ion storms in lysosomes. This nano‐drug regulates microglial phenotype switching from M1 to M2 while indirectly guiding neuronal differentiation of endogenous neural stem cells, thereby ameliorating ...

Intracellular self‐assembled nanoneedles for efficient lysosomal escape and CRISPR/Cas9 mediated gene editing

open access: yesBMEMat, EarlyView.
PlaMnB was formed by cytolysin A‐tumor homing peptides (THP)‐modified bacterial membranes encapsulating the clustered regularly interspaced short palindromic repeat/CRISPR‐associated protein (CRISPR/Cas9) plasmid and manganese dioxide. THP‐containing bacterial membrane enhances PlaMnB vascular permeability and tumor targeting, and after cellular ...

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine

open access: yesBMEMat, EarlyView.
Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Synthesis of Extracellular L-lysine-α-oxidase along with Degrading Enzymes by Trichoderma cf. aureoviride Rifai VKM F-4268D: Role in Biocontrol and Systemic Plant Resistance

open access: yesJournal of Fungi
When cultivating on wheat bran or deactivated fungal mycelium as a model of “natural growth”, the ability of Trichoderma to synthesize extracellular L-lysine-α-oxidase (LysO) simultaneously with cell-wall-degrading enzymes (proteases, xylanase ...

Platelet activating factor and lyso-phosphatidylcholines from strawberry

open access: yesPhytochemistry, 1996
Lipids from strawberry fruits, leaves, achenes and pollen were separated into classes by TLC, purified by HPLC and tested for biological activity. A lipid fraction from fruits with the same chromatographic behaviour as authentic platelet activating factor (PAF) showed identical biological activity, namely, dose-dependent aggregation of washed rabbit ...
