First demonstration of the Qa-SNARE syntaxin-17 (STX17) in human eosinophils.
High resolution immunogold EM shows STX17 in granules and tubular vesicles.
Unstimulated, TNF-伪 or CCL11-stimulated eosinophils express STX17.
Our findings suggest a role for STX17 in the transport of granule-derived cargos.
