Research Interests

Major research interests in this laboratory are twofold: The first examines the immunotoxicity and underlying mechanisms associated with inhaled indoor/outdoor pollutants such as woodsmoke, ozone, metals, and respirable particulate matter. Recent toxicological studies in our laboratory demonstrated that inhalation of smoke generated from the burning of a commonly used wood for home heating dramatically compromises pulmonary resistance against infectious bacterial agents. Alterations in host immunocompetence appear to be due, at least in part, to smoke-induced changes in the production of reactive oxygen/nitrogen species. We are also investigating effects on macrophage activation, cytokine biochemistry, and surface receptor expression as possible mechanisms responsible for the observed effects on bacterial resistance. Our results help explain the epidemiological evidence that suggests an increased incidence, duration, and severity of infectious respiratory diseases in children living in homes heated with woodburning devices.

The primary goal of our second research objective is developing alternative animal models for immunotoxicological studies. This work reflects the increasing social and political pressure to use nonmammalian models for predicting human health risks and to develop markers for assessing the biological effects of environmental stress. Studies using nonspecific, humoral, and cell-mediated aspects of the fish immune response, i.e., lymphoproliferation, cytokine activity, antibody formation, and free-radical production, have demonstrated its applicability for use as an alternative system to predict the immunotoxic effects of environmental contaminants and, possibly, for estimating human health risks.Selected Publications:
