Macrophage Extracellular Traps in Immunity and Cancer

open access: yesAdvanced Science, EarlyView.
As a macrophage‐mediated innate defense mechanism, the dysregulated release of METs drives chronic inflammation and influences tumor progression. Furthermore, METs exhibit a functional duality within the tumor microenvironment, capable of both promoting and suppressing tumor development.

3D Large‐Scale Subwavelength‐Resolution Sound Sheet Tomography Based on an Active and Programmable Circular Meta‐Array

open access: yesAdvanced Science, EarlyView.
A programmable 2048‐element circular ultrasound array combined with a compact acoustic lens produces a thin “sound sheet” over a large field of view, and records echoes with wide angular diversity across the ring aperture. Coherence‐enhanced beamforming converts full‐matrix data into high‐contrast tomographic slices, delivering near‐diffraction‐limited

Legumain Restrains Granuloma Formation by Inhibiting mTORC1/STAT1‐Mediated M1 Macrophage Polarization in Sarcoidosis

open access: yesAdvanced Science, EarlyView.
Legumain (LGMN) is upregulated in macrophages during sarcoid‑like granuloma formation. Macrophage‑derived LGMN binds to integrin αvβ3 and suppresses mTORC1/STAT1 signaling to restrain M1 macrophage polarization. Intratracheal delivery of lipid nanoparticles carrying Lgmn plasmid DNA (pDNA) elevates LGMN expression and effectively attenuates pulmonary ...
