Abstract_ Background Cockroach exposure is a major risk factor for the development of asthma. Inhalation of fecal remnants frass is the likely sensitizing agent however isolated frass has not been tested for its ability to induce experimental asthma in mice. Methods Mice Balb c or C57Bl 6 were sensitized and challenged with GC frass or GC frass devoid of proteases and measurements of airway inflammation and hyperresponsiveness were performed interleukin IL -5 -13 and interferon gamma IFNy levels in bronchoalveolar lavage fluid serum IgE levels airway hyperresponsiveness cellular infiltration and mucin production . Results Sensitization and challenge of .
