Inhalation Exposure Core

The mission of the Inhalation Exposure Core is to provide a specialized platform for the investigation of health impacts resulting from the inhalable environment and evaluation of therapeutics for the mitigation of respiratory disease, while serving as a valuable educational resource on the science and technology comprising this platform. The Inhalation Exposure Core provides short- and long-term generation, delivery, and analysis of precisely controlled atmospheres to investigate human health effects of environmental challenges using both in vitro and in vivo laboratory animal models. In coordination with Primate Medicine Services, the Inhalation Exposure Core also provides pulmonary function testing and bronchoscopy as outcome measures for health effects as a result of exposures in nonhuman primates. Minimally invasive methods, including pulmonary transfer impedance, are used for measuring pulmonary responses to disease processes, potential therapeutics, and changes across the lifespan. With an emphasis on inhalation toxicology and animal models of chronic respiratory disease, Inhalation Exposure Core faculty and staff provide critical intellectual expertise and technical support for investigators to conduct research projects that require evaluation of biological responses to atmospheric exposures.

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.
