As levels of VIP and NPY are up-regulated in diseases like allergy, asthma, and chronic rhinosinusitis, the balance of these two peptides in the airway may control mucus rheology and inflammatory responses in serous cells. Furthermore, the loss of CFTR conductance in serous cells may contribute to CF pathophysiology by increasing serous cells inflammatory responses in addition to directly impairing Cl− and HCO3− secretion.VIP and NPY are neuropeptides up-regulated in allergy and asthma, respectively, which inversely regulate CFTR-dependent secretion and inflammation in airway submucosal gland serous cells, and which secrete much of the fluid that lines conducting airways http://bit.ly/2FWNT29
