Outline of Final Research Achievements |
The aim of the present study was to clarify the action mechanism of neuropeptide Y (NPY), which was considered to be related to the cell permeability in neurogenic pulmonary edema (NPE), using two in vitro cell permeability evaluation systems of human normal lung microvascular endothelial cells (HMVEC-L) and human bronchial epithelial cell lines Calu-3. NPY at the concentration of 1.0E-7 M did not affect cell permeability in both systems. However, the addition of macrophage medium treated with 1.0E-8 M NPY significantly increased the Calu-3 cell permeability. These results suggest that NPY did not act directly on both endothelial and epithelial cells, but could cause the increase in the lung epithelial cell permeability via macrophage stimulation in NPE pathophysiology.
