CohortFemale B6C3F1/N mice, aged 5–6 weeks old were acquired from the National Toxicology Program and mouse colony housed at Taconic (Germantown, NY). Mice were acclimated for approximately one week prior to exposures and housed in filtered, ventilated polycarbonate cages in groups of 5 on autoclaved hardwood chip bedding.

Disease Introduction MechanismExposure to fungal bioaerosols in indoor environments has been associated with adverse respiratory health effects. Interest in understanding the mechanisms associated with fungal exposures has increased following recent natural disasters, including hurricanes Katrina, Rita, and more recently Sandy, that have resulted in the prolific contamination of flooded indoor building materials. Aspergillus fumigatus is a saprophytic mold naturally found in the environment that produces respirable asexual conidia. In some damp indoor environments, A. fumigatus can be found growing on common building materials such as wood, gypsum board, and chipboard and disturbance of these contaminated building materials can result in elevated personal exposure. To date, the influence of conidia viability on the microRNA (miRNA) and messenger RNA (mRNA) profiles underlying pulmonary immune and toxicological responses to A. fumigatus exposure are not fully characterized.
