"These data show that loss of membrane GM-CSFRalpha following GM-CSF exposure does not preclude sustained GM-CSF/GM-CSFRalpha signaling and that this receptor plays a key role in ligand clearance. Hence neutrophilic activation via GM-CSFR may play an important role in neutrophilic lung inflammation even in the absence of high GM-CSF levels or GM-CSFRalpha expression."xsd:string
