OMIA 001417-9685 : Pulmonary fibrosis, idiopathic in Felis catus

In other species: dog

Possibly relevant human trait(s) and/or gene(s) (MIM number): 178500 (trait)

Mendelian trait/disorder: unknown

Considered a defect: yes

Species-specific symbol: IPF

Species-specific description: The paper by Williams et al. (2004) is the first report of an animal model of human idiopathic pulmonary fibrosis.

Pathology: As reported by Williams et al. (2004), the histopathology comprises "(1) interstitial fibrosis with fibroblast/myofibroblast foci, (2) honeycombing with alveolar epithelial metaplasia and type II pneumocyte hyperplasia, and (3) alveolar interstitial smooth-muscle metaplasia. Interstitial inflammation was not a prominent feature of the disease. alpha-Smooth muscle actin-positive myofibroblasts were prominent in myofibroblast foci, beneath honeycomb and hyperplastic epithelium, and in alveolar septa away from the remodeling. Feline IPF type II pneumocyte ultrastructure is similar to a heritable form of human IPF, with abnormal cytoplasmic lamellar body-like inclusions. "
