Neutrophil chemotactic factor (NCF) is a slight acidic macromolecule which is released into the circulation of asthmatic individuals following antigen provocation and an exercise task. It also appears in late asthmatic reactions with a time course of appearance which precedes the second fall in FEV1. The release of NCF was inhibited by prior administration of disodium cromoglycate (DSCG) suggesting its possible mast cell origin.
