Gas Bubbles from Biodegradable Magnesium Implants Convey Mechanical Cues and Promote Immune Cell Stimulation

open access: yesAdvanced Science, EarlyView.
Bubbles in soft tissue are the unavoidable consequence of magnesium implant degradation in patients, yet their biological significance remains unclear. Using advanced imaging and spatial transcriptomics, this study reveals a pronounced inflammatory and mechanical response near bubbles, contrasting with pro‐regenerative events closer to the implant ...

Mechanotransduction Activates Microglia and Impairs Phagocytosis in Stiff Amyloid‐β Plaques

open access: yesAdvanced Science, EarlyView.
The study constructs an in vitro Aβ plaque‐associated microglia model and uses SECM and SICM to in situ monitor changes in ROS levels, membrane permeability, and phagocytosis of microglia during Aβ clearance. It is found out that Aβ stiffness triggers microglial activation via the PIEZO1 mechanotransduction pathway, causing neuroinflammation and ...

Exosomal CMTM4 Induces Immunosuppressive Macrophages to Promote Ovarian Cancer Progression and Attenuate Anti‐PD‐1 Immunotherapy

open access: yesAdvanced Science, EarlyView.
In ovarian tumors with high CMTM4 expression, exosomes transfer CMTM4 to macrophages, upregulating ICAM1 and promoting M2 polarization via p65 nuclear translocation. This suppresses immunity by increasing PD‐1 and Tregs while reducing CD8+ T cells.

A companion to the preclinical common data elements and case report forms for neuropathology studies in epilepsy research. A report of the TASK3 WG2 Neuropathology Working Group of the ILAE/AES Joint Translational Task Force

open access: yesEpilepsia Open, EarlyView., 2022
Abstract The International League Against Epilepsy/American Epilepsy Society (ILAE/AES) Joint Translational Task Force initiated the TASK3 working group to create common data elements (CDEs) for various aspects of preclinical epilepsy research studies, which could help improve the standardization of experimental designs.

Tyrosine phosphorylation and palmitoylation of TRPV2 ion channel tune microglial beta-amyloid peptide phagocytosis

open access: yesJournal of Neuroinflammation
Alzheimer’s disease (AD) is the leading form of dementia, characterized by the accumulation and aggregation of amyloid in brain. Transient receptor potential vanilloid 2 (TRPV2) is an ion channel involved in diverse physiopathological processes ...

Functionalized Biomimetic Nanoparticles Targeting the IL‐10/IL‐10Rα/Glycolytic Axis in Synovial Macrophages Alleviate Cartilage Degeneration in Osteoarthritis

open access: yesAdvanced Science, EarlyView.
The MOF material UIO‐66‐NH2 is functionalized with DBCO groups on its surface, encapsulating NO‐prednisolone and conjugating it with azide‐modified IL‐10. Finally, the complex is extruded with MM to form biomimetic functional nanoparticles. Upon intra‐articular injection, MI@UN, enveloped by the MM, specifically targets synovial macrophages, is ...

Wireless In Situ Catalytic Electron Signaling‐Mediated Transcriptomic Reprogramming for Neuron Regeneration via Adaptable Antennas

open access: yesAdvanced Science, EarlyView.
A wireless‐charging sustained oxygen release from conductive microgels (SOCO) served as an antenna and an on‐demand O2 release for nerve regeneration is developed. Introducing “electromagnetic messenger”, using external alternating magnetic field (AMF) to enhance catalytic oxygen release and electrical stimulation to promote the reconstruction of blood
