Mast cell extracellular granules are bioactive condensates assembled by heparin and polyamine
Xiong Y, Tomares D, Guo J, Sato K, Zeng L, Tian Y, Su M, Albis A, Pant A, Pappu R, Su X. Mast cell extracellular granules are bioactive condensates assembled by heparin and polyamine. Nature Chemical Biology 2026, 1-12. PMID: 41760814, PMCID: PMC13010460, DOI: 10.1038/s41589-026-02165-6.Peer-Reviewed Original ResearchThis study investigates how mast cell extracellular granules form via interactions between heparin and polyamines, creating unique microenvironments that enhance immune mediator activity.
