Stem cell factor-mediated activation pathways promote murine eosinophil CCL6 production and survival.

abstract：:The Charcot-Leyden crystal (CLC) protein, a prominent cell constituent unique to eosinophils and basophils, possesses lysophospholipase activity. This activity and the extracellular deposition and formation of CLC in tissues and body fluids in association with eosinophils suggest an extracellular function for this pro...
