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 including malaria, HIV, pneumonia, and diarrhea. We have ongoing collaborations with Drs. Lisa Frenkel and Heather Jaspan from Seattle Children’s, Dr. Marion Pepper from the University of Washington, and Dr. Lee Nelson from the Fred Hutchinson Cancer Research Center.
