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

Advanced 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 ...

Investigation of effects of two environmental heavy metals in a combined exposure model on the nervous system in rats [PDF]

, 2012
In the present study, the interaction of inhalational and oral exposure to manganese and lead was investigated. Young adult male Wistar rats (2 x 10 per group) were treated orally with MnCl2 (15 and 60 mg/kg b.w.) or Pb acetate (80 and 320 mg/kg) for 3 ...

Self‐Amplifying Redox Cycle Triggers Ferroptosis/Cuproptosis Synergy for Enhanced Bacterial Eradication

Advanced Science, EarlyView.
This study designs a targeted nanocomposite (ct@HMCF‐Dex) that responds to acidic infection microenvironments, releasing components which amplify oxidative stress. It disrupts bacterial redox balance, chelates metals to sustain lipid peroxidation, and synergistically induces cuproptosis/ferroptosis‐like death.

Building an international precision medicine platform trial for the acute respiratory distress syndrome (ARDS): an expert consensus project report

Efficacy and Mechanism Evaluation
Background Almost all large-scale trials of disease-modifying therapeutic agents in critical care have failed to show benefit for patients, which may be explained in part by the clinical and biological heterogeneity inherent in virtually all critical ...

Ligation of protease-activated receptor 1 enhances alpha(v)beta(6) integrin-dependent TGF-beta activation and promotes acute lung injury [PDF]

, 2006
Activation of latent TGF-beta by the alpha(v)beta(6) integrin is a critical step in the development of acute lung injury. However, the mechanism by which a alpha(v)beta(6)-mediated TGF-beta activation is regulated has not been identified.

Thy-1 interaction with Fas in lipid rafts regulates fibroblast apoptosis and lung injury resolution. [PDF]

, 2017
Thy-1-negative lung fibroblasts are resistant to apoptosis. The mechanisms governing this process and its relevance to fibrotic remodeling remain poorly understood. By using either sorted or transfected lung fibroblasts, we found that Thy-1 expression is

Methylophiopogonanone a attenuates pulmonary fibrosis by inhibiting SPP1‐mediated macrophage polarization via the PI3K/Akt pathway

Animal Models and Experimental Medicine, EarlyView.
Transcriptome sequencing identified secreted phosphoprotein 1 (SPP1) as a crucial target through which methylophiopogonanone A (MOA) ameliorates pulmonary fibrosis. Molecular docking and microscale thermophoresis (MST) assays confirmed a favorable binding affinity between MOA and SPP1.
