MiRNA chronic OVA aerosol
Ontology highlight
ABSTRACT: specific pathogen-free female BALB/c mice aged 7-8 weeks (Animal Resources Centre, Perth, Western Australia) were systemically sensitised by intraperitoneal injection of 50 M-5g of alum-precipitated chicken egg OVA (Grade V, ?98% pure, Sigma Australia) 21 and 7 days before inhalational challenge, then exposed to aerosolised OVA in a whole body inhalation exposure chamber (Unifab Corporation, Kalamazoo, MI). Chronic low-level challenge involved exposure to ?3 mg/m3 aerosolised OVA for 30 minutes/day on 3 days/week for up to 6 weeks. Particle concentration within the chamber was continuously monitored using a DustTrak 8520 instrument (TSI, St Paul, MN). All experimental procedures complied with the requirements of the Animal Care and Ethics Committee of the University of New South Wales (reference numbers: 06/119B and 08/09B). Mice were sacrificed after 1,2,4 and 6 weeks of OVA exposure. Control groups included naM-ove mice and mice that were not sensitised but were challenged for 6 weeks with aerosolised OVA.
