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 %U //www.qdcxjkg.com/content/erj/55/4/1901386.full.pdf
