These results demonstrate that there are increased numbers of activated eosinophils and GM-CSF is increased in patients with mild asthma. Furthermore, GM-CSF is correlated with eosinophil number and function in vivo and these indices are significantly correlated with airway function. These findings emphasize the importance of eosinophils, potentially regulated in vivo by GM-CSF, in contributing to the disordered airway function evident even in mild asthma. ER -
