Research Centers and Programs
Welcome to the Harrington Lab
The Harrington Lab focuses on intergenerational immune interactions and their effect on susceptibility to infection during pregnancy and infection. In particular, we investigate the role of maternal microchimerism (maternal cells acquired by the fetus in utero) in fetal and infant immune development, early vaccine responses, and susceptibility to infection. We have ongoing collaborations with Drs. Lisa Frenkel and Heather Jaspan from Seattle Children’s, Drs. Marion Pepper and Hilary Gammill from the University of Washington (UW) and Dr. Lee Nelson from the Fred Hutchinson Cancer Research Center.
Current Research Projects
We have previously demonstrated that malaria infection and inflammation of the placenta results in infants acquiring more maternal cells. In addition, we found that infants with detectable maternal cells were more susceptible to malaria infection but, interestingly, less likely to be sick from their infections. Current projects in the lab include isolating and phenotyping the maternal cells, determining whether infants acquire a maternal graft with immunologic memory, and whether the maternal cells affect the development of immune responses against malaria and HIV.
