25-Hydroxycholesterol Reprograms Tumor Macrophages
2026-08-11
The 2024 Immunity study identifies CH25H-derived 25-hydroxycholesterol as an immunometabolic checkpoint that activates lysosomal AMPKα and reinforces STAT6-dependent macrophage suppression. Its mechanistic and therapeutic findings connect cholesterol metabolism with T-cell exclusion and suggest that targeting CH25H may improve anti-PD-1 responses.

Nanoparticle Uptake by Human Corneal Epithelial Cells
2026-08-11
Azadi and David systematically linked PLGA nanoparticle size and surface chemistry to uptake mechanisms in human corneal epithelial cells. Their in vitro model showed that energy-dependent endocytosis predominated, with macropinocytosis and caveolae-mediated uptake contributing most strongly, while particle size and PEGylation produced distinct uptake profiles.

25-Hydroxycholesterol Drives Immunosuppressive Macrophage Re
2026-08-06
Xiao et al. (2024) reveal that 25-hydroxycholesterol (25HC), produced by CH25H, accumulates in macrophage lysosomes to activate AMPKα, altering macrophage metabolism and promoting immunosuppressive tumor-associated phenotypes. This work uncovers a mechanistic link between oxysterol metabolism and tumor immune evasion, highlighting CH25H as a potential immunometabolic checkpoint for cancer immunotherapy.
