A Blood‐Brain Barrier‐Penetrant Ag(III) Corrole Compound Rescues Alzheimer's Disease Pathology by Targeting Aβ42‐Induced Oxidative Stress

Advanced Science, EarlyView.
The newly designed metallo‐corrole (Mor‐Cor)Ag(III) with a morpholino group exhibited promising therapeutic potential for Alzheimer's disease. It significantly reduces reactive oxygen species (ROS), decreases GFAP expression, increases neurite length, and decreases cell death compared to other similar metallo‐corroles. Abstract Alzheimer's disease (AD)

Brd4 BD1 Domain Antagonism of MS436 Preserves Blood‐Brain Barrier Integrity via Rnf43/β‐Catenin Signaling Pathway

Advanced Science, EarlyView.
MS436 competitively binds to the BD1 domain of Brd4, thereby suppressing Brd4 induced degradation of tight junction proteins via the Rnf43‐Fzd4‐β‐catenin signaling pathway. Consequently, this attenuation of degradation reduces blood‐brain barrier leakage, leading to an improved overall prognosis after stroke.

Stimuli‐Responsive Supramolecular Biomaterials for Cancer Theranostics

Advanced Science, EarlyView.
The ultimate goal of cancer theranostics is to get imaging agents and therapeutic cargo to tumor sites when and where they are required. “Smart” systems should be developed. This review discusses the characteristics of physiological stimuli, types and action modes of external stimuli, construction approaches and working principles, as well as ...

Esketamine/Ketamine: Dual‐Action Mechanisms and Clinical Prospects beyond Anesthesia in Psychiatry, Immunology, and Oncology

Advanced Science, EarlyView.
Esketamine and ketamine are widely used for perioperative analgesia and anesthesia. Despite their established roles in analgesia, sedation, and anesthesia, as well as emerging antidepressant, anti‐tumor, and anti‐inflammatory effects, their clinical use is limited due to side effects and addiction potential.

S3RL: Enhancing Spatial Single‐Cell Transcriptomics With Separable Representation Learning

Advanced Science, EarlyView.
Separable Spatial Representation Learning (S3RL) is introduced to enhance the reconstruction of spatial transcriptomic landscapes by disentangling spatial structure and gene expression semantics. By integrating multimodal inputs with graph‐based representation learning and hyperspherical prototype modeling, S3RL enables high‐fidelity spatial domain ...

Islet Amyloid Polypeptide Modelled to Simulate Diabetes Co‐Oligomerized with β‐Amyloid 1‐42 Reproducing the Pathological Cascade of Alzheimer's Disease in Human Cerebral Organoids

Advanced Science, EarlyView.
Human islet amyloid polypeptide (hIAPP) was used to mimic T2DM, and Aβ42‐hIAPP co‐oligomers were delivered into the human mature cerebral organoids (COs), which reproduce typical AD pathology and significant neuronal death more closely resembling that of AD patients.

Crossing the Blood–Brain Barrier with Molecularly Imprinted Polymeric Nanocarriers: An Emerging Frontier in Brain Disease Therapy

Advanced Science, EarlyView.
Molecularly imprinted polymeric nanocarriers (nanoMIPs) offer robust, antibody‐mimetic platforms to overcome the blood‐brain barrier. The article surveys nanoMIP design and ligand‐directed surface engineering that harness receptor‐mediated transcytosis, and highlights therapeutic and diagnostic applications in neurodegeneration, brain tumors and ...
