Hypersection of mucus in the lungs is inhibited by the administration of an epidermal growth factor receptor (EGF-R) antagonist. The EGF-R antagonist may be in the form of a small organic molecule, an antibody, or portion of an antibody that binds to and blocks the EGF receptor. The EGF-R antagonist is preferably administered by injection in an amount sufficient to inhibit formatio of goblet cells in pulmonary airways. The degranulation of goblet cells that results in airway mucus production is thereby inhibited. Assays for screening candidate agents that inhibit goblet cell proliferatio are also provided.

l'administration d'un récepteur du facteur de croissance épidermique (EGF-R) empêche l'hypersécrétion de mucus dans les poumons. L'antagoniste de EGF-R peut se présenter sous la forme d'une petite molécule organique, d'un anticorps ou d'une partie d'anticorps que se lie avec le récepteur EGF et le bloque. L'antagoniste de EGF-R est de préférence administré par injection en quantité suffisante pour inhiber la formation de cellules caliciformes dans les voies respiratoires pulmonaires. On inhibe ainsi la dégranulation des cellules caliciformes qui entraînent la production de mucus dans les voies respiratoires. L'invention concerne également des test de criblage d'agents candidats qui inhibent la prolifération de cellules caliciformes.
