digestive/alimentary system

intestinal obstruction ( J:112450 )

• develop intestinal blockage when fed a normal (solid) diet

growth/size/body

postnatal growth retardation ( J:112450 )

• weighed significantly less (P 0.05) than homozygote wild-type controls at 14 and 21 days of age

immune system

lung inflammation ( J:112450 )

• increased inflammatory response to chronic Pseudomonas aeruginosa infection, identical to that in Cftr^tm1Unc homozygotes

increased susceptibility to bacterial infection induced morbidity/mortality ( J:112450 )

• reduced ability to respond to lung infection elicited with Pseudomonas aeruginosa- laden agarose beads

mortality/aging

increased susceptibility to bacterial infection induced morbidity/mortality ( J:112450 )

• reduced ability to respond to lung infection elicited with Pseudomonas aeruginosa- laden agarose beads

respiratory system

lung inflammation ( J:112450 )

• increased inflammatory response to chronic Pseudomonas aeruginosa infection, identical to that in Cftr^tm1Unc homozygotes

decreased respiratory epithelial chloride transmembrane transport ( J:112450 )

• after treatment with a chloride-depleted solution with amiloride and forskolin, the nasal potential difference (PD) was significantly different between control mice and homozygous mice
