Mouse Model of Allergic Asthma

To develop pulmonary eosinophilia, mice are sensitized with chicken egg ovalbumin (OVA) precipitated in aluminium sulphate on experimental days 0 and 14. On experimental day 20 mice are intranasally challenged with OVA, under light anesthesia.

Bronchoalveolar lavage samples and lungs are collected at 48h after challenge. 

Species, strain, sex:
BALB/c J mice, males
Number of animals /group:
Pharmacological control:
dexamethasone, days 18–21,
once daily at the dose of 1 mg/kg
Routes of administration:
upon request
Treatment mode:
upon request
Duration of dosing:   
upon request
Main read-outs:
total and relative  cell count in bronchoalveolar lavage fluid (BALF)
histopathological analysis of the lungs
Facultative read-outs:
cytokines/chemokines: gene expression and protein levels in lung fluid cells/lungs
phenotypic analysis of lavage cells (FACS analysis)

Histology of lungs (HE)
