Inhalation Exposure Core
The mission of the Inhalation Exposure Core is to provide a specialized scientific resource for the assessment of health impacts resulting from inhaled environmental constituents and evaluation of therapeutics for the mitigation of cardiorespiratory disease while serving as an educational resource for the technology comprising this service. The Inhalation Exposure Core encompasses state-of-the-art facilities for the short- and long-term generation of precisely controlled atmospheres and delivery to both in vitro and in vivo laboratory animal models under the guidance of CNPRC Core and Affiliate Scientists. The Inhalation Exposure Core also supports the assessment of cardiorespiratory function and bronchoscopic collection of lung specimens for in vivo disease characterization, as well as response to clinical and preclinical therapeutics.

Beginning in 2000, under the leadership of Dr. Charles G. Plopper (UC Davis School of Veterinary Medicine, Emeritus), an important and major effort was initiated to study the development and exacerbation of asthma by oxidant air pollutants in nonhuman primates. The asthma studies necessitated the establishment of a pulmonary function laboratory with extensive capabilities for testing nonhuman primates under the direction of a pulmonary physiologist to assess function in animals undergoing exposure. Under the leadership of Dr. Dallas Hyde (UC Davis School of Veterinary Medicine, Emeritus), funding was obtained in 2010 from the US government – American Recovery and Regeneration Act – to build a Respiratory Disease Centerincluding a new inhalation exposure facility. It was recognized that the CNPRC is the only primate center with an inhalation exposure facility and respiratory diseases unit, enhancing research with nonhuman primate models of respiratory diseases.
