Structural and Functional Characterization of EXPO‐Derived Extracellular Vesicles in Plants

open access: yesAdvanced Science, EarlyView.
In this study, 3D electron tomography (ET), cryo‐ET, and immunogold transmission electron microscopy (TEM) are employed to characterize plant extracellular vesicles (EVs) under physiological conditions. EVs are classified into three distinct categories according to their size, content, and molecular‐marker profiles. Furthermore, Exo70E2‐positive medium

Asparagusic Golgi Trackers

open access: yesJACS Au
Thiol-mediated uptake (TMU) is thought to occur through dynamic covalent cascade exchange networks. Here we show that the cascade accounting for TMU of asparagusic acid derivatives (AspA) ends in the Golgi apparatus (G) and shifts from disulfide to thioester exchange with palmitoyl transferases as the final exchange partner.

Nanoscale Mapping of the Subcellular Glycosylation Landscape

open access: yesAdvanced Science, EarlyView.
Using multiplexed super‐resolution imaging with fluorophore‐labeled lectins, this study reports intracellular glycosylation at the nanoscale across organelles and synaptic specializations. Extending glycan analysis beyond the cell surface, Glyco‐STORM reveals distinct glycosylation nanodomains in the ER, Golgi, lysosomes, and synaptic sites.

Generation and Characterization of a Tissue-Specific Centrosome Indicator Mouse Line. [PDF]

open access: yes, 2016
Centrosomes are major microtubule organizing centers (MTOCs) that play an important role in chromosome segregation during cell division. Centrosomes provide a stable anchor for microtubules, constituting the centers of the spindle poles in mitotic cells,

HRS Degradation‐Induced Nicotinamide Deficiency in Placental Extracellular Vesicles Triggers Preeclampsia by Disrupting Maternal‐Fetal Immune Homeostasis

open access: yesAdvanced Science, EarlyView.
This study shows that lower NAM levels in PE‐derived pEVs correlate with disease severity. NAM‐deficient pEVs reduce Th1 and Th17 inhibition, leading to PE‐like symptoms. NAM in pEVs inhibits Th1 via SIRT1 and Th17 via macrophages. Reduced NAM in PE‐EVs is due to decreased HRS expression in trophoblasts, resulting from elevated HSP27.

Investigating Mitochondrial Viscosity in Ferroptosis‐Mediated Drug‐Induced Liver Injury using a Double‐Targeted Strategy

open access: yesAdvanced Science, EarlyView.
Utilizing a mitochondrial double‐targeted strategy, a novel near‐infrared fluorescent probe (FTZ‐2) is established for monitoring viscosity variations in ferroptosis‐mediated drug‐induced liver injury. In summary, this work provided a practical strategy for the early diagnosis and evaluation of liver injury.

Photocatalytic and Oxidative Synthetic Pathways for Highly Efficient PANI-TiO2 Nanocomposites as Organic and Inorganic Pollutant Sorbents

open access: yesNanomaterials, 2020
Polyaniline (PANI)-materials have recently been proposed for environmental remediation applications thanks to PANI stability and sorption properties. As an alternative to conventional PANI oxidative syntheses, which involve toxic carcinogenic compounds ...

A Hydrodynamic Bioreactor for High‐Yield Production of Extracellular Vesicles from Stem Cell Spheroids with Defined Cargo Profiling

open access: yesAdvanced Science, EarlyView.
This study harnesses hydrodynamic flows to generate, confine and stimulate stem cell spheroids, enabling the large‐scale production of extracellular vesicles (EVs). This innovative method not only streamlines spheroid formation and subsequent EV release in a single, integrated process, but also ensures the generation of EVs with enhanced biological ...

Potent and Long‐Lasting Immunogenicity Generated by LNP‐mRNA gE Antigen Against Varicella Zoster Virus via an AI‐Assisted Pipeline

open access: yesAdvanced Science, EarlyView.
This study designs a novel mRNA‐LNP vaccine targeting VZV glycoprotein E (gE) for herpes zoster via an AI‐assisted pipeline. Validated in mice and rhesus macaques, the mRNA‐LNP vaccine shows strong humoral and cellular immune responses, with CD4+ T‐cell responses more effective and durable than Shingrix, offering a promising prophylactic option ...
