Weller. 2008. “Electron Tomography and Immunonanogold Electron Microscopy for Investigating Intracellular Trafficking and Secretion in Human Eosinophils.” Journal of Cellular and Molecular Medicine 12 (4) (April 10): 1416–1419. doi:10.1111/j.1582-4934.2008.00346.x.1582-1838http://nrs.harvard.edu/urn-3:HUL.InstRepos:28993616Electron tomography (ET) has increasingly been used to understand the complexity of membrane systems and protein-trafficking events. By ET and immunonanogold electron microscopy, we recently defined a route for vesicular transport and release of granule-stored products from within activated human eosinophils, cells specialized in the secretion of numerous cytokines and other proteins during inflammatory responses. Here, we highlight these techniques as important tools to unveil a distinct eosinophil vesicular system and secretory pathway.en-USJournal Article2016-10-0610.1111/j.1582-4934.2008.00346.x
