Near‐Infrared Fluorescent PROTAC Enables Theranostic Imaging and Selective Tau Degradation in Alzheimer's Disease

open access: yesAdvanced Science, EarlyView.
Here, we report a novel NIR fluorescent PROTAC platform that enables real‐time imaging and targeted degradation of Alzheimer's p‐Tau. Our lead compound effectively clears p‐Tau, reduces APP/Aβ, and alleviates cognitive deficits in AD mice. This work demonstrates a theranostic strategy for visualizing degradation and developing next‐generation AD ...

An Injectable Metal‐Drug Supramolecular Condensate Enables Radiosensitization and Systemic Antitumor Immunity for Post‐Surgical Osteosarcoma Therapy

open access: yesAdvanced Science, EarlyView.
This work designed an injectable metal‐drug supramolecular condensate formed from hafnium ions and alendronate (Hf‐ALN) and loaded with the COX‐2 inhibitor celecoxib (CXB) for synergistic radioimmunotherapy of postoperative osteosarcoma. Mechanistically, upon X‐ray irradiation, Hf enhances radiation energy deposition, ROS generation, and DNA damage ...

Mitochondria‐Targeted Multimodal Nanotherapeutics Suppress Oxidized mtDNA‐Driven Inflammation at the Source

open access: yesAdvanced Science, EarlyView.
Ox‐mtDNA fragments escaping from mitochondria drive robust inflammatory responses. A targeted nanoplatform simultaneously inhibits mitochondrial FEN1‐mediated mtDNA cleavage and scavenges ROS, preventing the generation of immunogenic Ox‐mtDNA fragments. The released SeNPs further promote autophagic clearance of cytosolic mtDNA. Consequently, cGAS‐STING,

L-Alanine : α-ketoglutarate transaminase from Aspergillus awamori; purification and properties (Department of Agricultural Chemistry)

open access: yes
各種カビにおけるL-アラニン : α-ケトグルタル酸トランスアミナーゼ活性を調べた結果, 泡盛麹菌(Asp. awamori IFO4122)を蔗糖-ペプトン含有培地で振とう培養し, 得られた菌体の無細胞抽出液中に高い酵素活性が得られた。本酵素はL-アラニンとα-ケトグルタル酸からL-グルタミン酸とピルビン酸を生成するアミノ基転移反応を触媒し, 本反応の逆反応も触媒した。本酵素は, 供試泡盛麹菌株の無細胞抽出液から硫安分画及び各種のカラムクロマトグラフィーにより55倍に精製された ...

Intelligent Programmable Membrane Nanosponge for Early Virus Blocking

open access: yesAdvanced Science, EarlyView.
A smart programmable nanosponge (ACNPs) displays high‐density viral receptors on its membrane and encapsulates fusion inhibitors to capture virions at the infection source through competitive binding and blocks their entry through protease inhibition for ultra‐early cascade interception. This modular, mucus‐penetrating platform shifts antiviral defence

Supramolecular Zinc–Polyphenol Coordination Assemblies Mitigate Colonic Inflammation by Regulating Mucosal Barrier and Microbiome

open access: yesAdvanced Science, EarlyView.
A carrier‐free zinc‐coordinated polyphenol nanoplatform (ZnCA NPs) is designed as an “all‐in‐one” therapeutic strategy for intestinal inflammation. The ZnCA NPs exhibit enhanced colonic accumulation and broad‐spectrum reactive oxygen and nitrogen species scavenging.

Multifunctional Nanovaccine‐Radiotherapy Synergy Drives Anti‐Tumor Immunity via Multi‐Cascade Cell Death for Pancreatic Cancer Therapy

open access: yesAdvanced Science, EarlyView.
Machine‐learning‐driven transcriptomic analysis identifies FSTL3 as a key tumor‐microenvironment regulator in desmoplastic pancreatic adenocarcinoma. A cRGD‐modified liposome co‐loading gemcitabine and siFSTL3 serves as an irradiation‐triggered in situ nanovaccine. It synergizes with radiotherapy to induce ferroptosis and immunogenic cell death through
