Generation 27 and 28 Cftrtm1Hgu/Cftrtm1Hgu mice exhibit focal hypertrophy of goblet cells
mortality/aging
|
• Background Sensitivity: in early generations, 8-10% die of intestinal obstruction around weaning, survival is 76% at 3 months of age for the F8-F10 generations, early deaths are still seen at F18, but by the 25th generation, no increased mortality over wild-type is seen
|
digestive/alimentary system
|
• F28 mice show focal hypertrophy of goblet cells in the ileum, but not in the jejunum
|
|
• Background Sensitivity: 8-10% of mutants in the early generations die of intestinal obstruction at weaning, however later generations do not exhibit intestinal blockage
|
reproductive system

• males and females are fertile

immune system
|
• mutants exposed to S. aureus exhibit increased lymphoid infiltrate and bronchiolitis compared to wild-type
• mutants exposed to B. cepacia exhibit much more severe bronchopneumonia and mixed inflammatory infiltrate than wild-type
|
|
• mutants are unable to clear Staphylococcus aureus and Burkholderia cepacia from the lungs and develop lung disease after repeated bacterial exposure
|
respiratory system
N |
• under normal conditions (without bacterial exposure), no lung abnormalities are detected in homozygotes
|
|
• mutants exposed to S. aureus exhibit increased lymphoid infiltrate and bronchiolitis compared to wild-type
• mutants exposed to B. cepacia exhibit much more severe bronchopneumonia and mixed inflammatory infiltrate than wild-type
|
|
• mutants exhibit lung disease in response to repeated bacterial exposure
• mutants exhibit increased lymphoid infiltrate, goblet cell hyperplasia, mucus retention in the airways, bronchiolitis compared to wild-type after S. aureus infection
• mutants exhibit severe bronchopneumonia and mucus retention in the major airways, goblet cell hyperplasia and metaplasia, massive mixed inflammatory infiltrate, obliteration of smaller airways, and extensive oedema compared to wild-type after B. cepacia infection
|
|
• mutants exposed to bacteria (S. aureus and B. cepacia) exhibit increased goblet cell hyperplasia compared to wild-type

|
mortality/aging
|
• low incidence of lethality due to intestinal blockage; 5% die within 1 week of birth and 2% die around weaning, with 93% surviving to adulthood
|
digestive/alimentary system
|
• mild colon dilatation with abnormal mucus accumulation
• distension of epithelial cells, most prominent in the crypts
|
|
• approximately 5% incidence of fatal meconium ileus
|
|
• chloride ion transport is altered as indicated by reduced rectal and colonic/caecal potential differences
|
respiratory system
|
• one mutant at P30 showed mild focal pulmonary atelectasis, with mucus obstruction of a small bronchus
|
|
• chloride ion transport in the nose is defective as indicated by an increased nasal potential difference, but no difference is seen throughout the lower airways below the larynx
• perfusion of the trachea with a low-chloride solution shows a reduction in resultant hyperpolarization
|
reproductive system
|
• one male exhibited increased mucin in the vas deferens
