Poly I:C causes exacerbation in a murine allergic inflammation model driven by house dust mite in Freund's complete adjuvant

Background RNA viruses are major causes of respiratory infections and known to exacerbate asthma and other respiratory diseases. The objective of the study was to use poly I:C, a synthetic analogue dsRNA, to elicit exacerbation in a model of allergic inflammation driven by house dust mite (HDM) in Freund’s Complete Adjuvant (FCA). This model is characterized by airway hyperresponsiveness (AHR) and a mixed T-helper phenotype [1].
