Alternaria Alternata


  • Intranasal (i.n.)  administration of Alternaria induces an influx of neutrophils, eosinophils and cytokines primarily associated with TH2-type inflammation 24 hours following challenge in BAL fluid.


  • Alternaria alternata is a fungal spore that can cause exacerbation of symptoms in asthma patients. This model serves as an alternative to other steroid sensitive models, mimicking several key aspects of human allergic asthma over a shorter duration.
