Modulation of Subcellular Redox Homeostasis with Trialkylphosphines

Jade Noémie Nam Nguyen

Redox homeostasis is essential for cell function and its disruption is associated with multiple pathologies. Redox balance is largely regulated by the relative concentrations of reduced (GSH) and oxidized (GSSG) glutathione. In eukaryotic cells, this ratio ...

Macrophage depletion induces edema through release of matrix-degrading proteases and proteoglycan deposition

Michele De Palma

Colony-stimulating factor 1 receptor (CSF1R) blockade abates tumor-associated macrophage (TAM) infiltrates and provides marked clinical benefits in diffuse-type tenosynovial giant cell tumors. However, facial edema is a common adverse event associated with ...

Co-regulation of endothelial and myogenic cell fates through intercellular crosstalk in skeletal muscle

Umji Lee

Skeletal muscle is one of the most dynamic organs in the human body, which has a vigorous potential to regenerate and adapt to environmental changes. Depending on environments, skeletal muscle enables essential life activities to survive by controlling mov ...

Dual-Activatable Cell Tracker for Controlled and Prolonged Single-Cell Labeling

Pablo Rivera Fuentes, Salome Riccarda Püntener

Cell trackers are fluorescent chemical tools that facilitate imaging and tracking cells within live organisms. Despite their versatility, these dyes lack specificity, tend to leak outside of the cell, and stain neighboring cells. Here, we report a dual-act ...
