Label‐Free Molecular Characterization of Protein Aggregates in Differentiated Astrocytes

Advanced Science, EarlyView.
Mid‐infrared photothermal microscopy enables label‐free structural, molecular, and functional imaging of protein aggregates in astrocyte cells. The processes of astrocytes differentiated on a nanomaterial interface are characterized by α‐helical signatures combined with enhanced interfacial thermal resistance properties, while the cell soma of non ...

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.

CD147/Basigin: From Integrative Molecular Hub to Translational Therapeutic Target

Advanced Science, EarlyView.
This review conceptualizes CD147 as a fundamental “Energy‐Structure Coupler,” physically bridging metabolic flux (via MCTs) with morphogenetic plasticity (via integrins/MMPs) to drive cancer, infection, and autoimmunity. Addressing the “specificity paradox” that limits current translation, the authors chart a strategic roadmap—spanning logic‐gated ...

Botulinum neurotoxin Light Chain/A1 uses fast synaptic vesicle cycling to cleave plasma membrane bound SNAP-25

Communications Biology
Botulinum neurotoxins (BoNT) are the most potent protein toxins for humans, yet how BoNT-Light Chain/A1 (LC/A1) journeys to cleave intracellular SNAP-25 is understudied.

Tumor Extracellular Vesicles lncOSLMT Drives Lung Inflammatory Premetastatic Niche Formation in Osteosarcoma via m6A‐Dependent hnRNPA2B1/COX‐2 Axis

Advanced Science, EarlyView.
Tumor‐derived extracellular vesicles program inflammatory lung premetastatic niches through selective delivery of long noncoding RNAs. This work reveals EVs‐associated lncOSLMT as a key driver of lung fibroblast activation via m6A‐dependent PTGS2 stabilization.

Immunoaffinity‐Mimetic Assembly of Peptide‐Aptamer Conjugates and Stem Cell‐Derived Exosomes into Hierarchical Microgels for Spinal Cord Injury Repair

Advanced Science, EarlyView.
Inspired by antibody‐antigen binding, this study develops an unprecedented immunoaffinity‐mimetic assembly strategy, with Peptide‐AptCD63 conjugates acting as antibody surrogates binding CD63 epitopes on mesenchymal stem cell‐derived exosomes. This creates a hierarchical microstructure intended to synergistically integrate antioxidative and anti ...

Traceless Regulation of Genetic Circuitry

Advanced Science, EarlyView.
Energy‐based, as opposed to molecular, control offers unprecedented improvements in key circuit parameters. This review summarizes the fundamentals of such traceless switches, categorizes them by trigger modalities, and compares and contrasts distinct advantages as well as shortcomings of each kind.
