Hypersecretion of mucus in the lungs is inhibited by the administration of an epidermal growth factor re-ceptor (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 ad-ministered by injection in an amount sufficient to inhibit formation of goblet cells in pulmonary airways. The de-granulation of goblet cells that results in airway mucus production is thereby inhibited. Assays for screening candidate agents that inhibit goblet cell proliferation are also provided.

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