In order to study the stromal molecular mechanisms involved in T cell development, we isolated new genes, by quantitative differential screening using array technology, between wild-type and several knock-out mice models displaying a stromal disorganization.
Second, the transgenic mouse models display aberrant expression of peptide-specific TCRα and β transgenes, which bypasses the thymic negative selection and consequently lead to the escape of an unusual large number of autoreactive T-cells in periphery [38].
Whereas, in humans, CL/P is more common than CP, most mouse models display CP.
Previous Notch-driven mammary-tumor mouse models display varying phenotypes, ranging from mammary hyperplasia and DCIS in nulliparous mice to lactation-dependent regressing tumors and nonregressing invasive adenocarinomas [ 8, 31- 33].
Some of these mouse models display embryonic lethality, others relatively little phenotype, but several have clinical phenotypes similar to the respective human diseases, enabling preclinical trials to be performed.
For the Wnts, none of the published Wnt knockout mouse models display a phenotype that would suggest a clear role in patterning of the nephron, although both Wnt9b and Wnt7b, when deleted, alter nephron morphogenesis.
Although these mouse models display a range of psychiatric disease-related behavioral phenotypes, many have been inconsistent across studies due to differences in behavior tests and experimental design and the specific genetic aberrations.
The hamster prion promoter (hPrP -APP transgenic mouse models display a disinhPrP -APPlike phenotransgenice elevated-plus mouseand hyperactivity in somodelsas, such as in the open fieldisplay 47], which we confirmed for aPP695 mice comparedisinhibition-like) mice.
Although these two transgenic mouse models display neuronal loss, cholinergic deficit, cognitive impairments, amyloid plaques and neuroinflammation in old age, the onsets of amyloid plaque formation and cognitive decline between them are very different in early adulthood [ 5, 8, 9, 30, 38, 56].
The IL-1R antagonist (IL-1RA) knockout mice model displays uncontrolled IL-1 signalling and leads to the development of chronic arthritis [ 47].
