BPIFB1 and BPIFA1 are increased in the occluded airways of scgb1a1-ENaC transgenic mice. Immunohistochemistry was performed as described in "Materials and methods" using antibodies specific for murine BPIFB1 (a, c, e, g, i, j) and BPIFA1 (d, f, h, k, l) and SCGB1A1 (b). Sections show serial samples of lungs from 2 week old wild type mice (a, b), 2 week old transgenic mice (c, d) 6 week old wild type mice (e–f) and 6 week old transgenic mice (g–l). Scale bars are present on each individual panel
