How Cholesterol Hinders LNP Intracellular Trafficking
2026-08-16
A 2025 International Journal of Pharmaceutics study developed a streptavidin–biotin-DNA tracking platform with high-throughput imaging to resolve how lipid nanoparticle composition affects intracellular trafficking. Its central finding is that increasing cholesterol promotes peripheral early-endosome accumulation, restricts progression through the endolysosomal pathway, and reduces nucleic-acid delivery efficiency, whereas DSPC can partially alleviate this effect.

GSK3 Inhibition as Host-Directed TB Therapy
2026-08-12
The 2024 iScience study identifies glycogen synthase kinase 3 as a host pathway that supports intracellular Mycobacterium tuberculosis growth. By combining pharmacological screening, CRISPR knockout, RNA interference, apoptosis analysis, and phospho-proteomics, the authors establish GSK3 inhibition as a mechanistically supported host-directed strategy rather than a conventional antibacterial approach.
