The core of our research focuses on the pathopharmacology of the maternal-placental-fetal unit. Intrauterine infection is a major threat to mother and baby. It is associated with more than 50% of women who deliver prematurely and is implicated in fetal / neonatal neurological and respiratory damage. Our data indicate there are changes in drug transport proteins in placenta of women with infection and associated chorioamnionitis. Changes in placental transporters could result in altered fetal drug exposure leading to therapeutic insufficiency or drug toxicity. Our research addresses three core questions. First, how do pathophysiological responses to infection affect placental drug transporters? Second, do pathological changes in transporter expression levels correlate with placental drug transfer, and therapeutic outcome? Finally, what are the regulatory pathways that drive transporter expression and can pharmacoresistance to drugs be overcome by targeted inhibition of proteins within these pathways? Our laboratory seeks to test the hypothesis using mouse models of infection-induced chorioamnionitis. The results will help predict how pathophysiological responses to infection during pregnancy alter placental transfer and therapeutic efficacy of drugs.
