Enteroid Core - Pathogenesis of E. Coli and Shigella Infections in Human Enteroid Models

点击翻译按钮获取中文摘要

Project Summary The Enteroid Core will provide enteroids/colonoids from our established JHU biobank to investigators of this P01 as frozen stocks, instruction given on how to culture and propagate the enteroids, how to use conditioned media and how to make enteroid/colonoid monolayers. Conditioned media will be prepared and provided to the investigators weekly. In collaboration with the Immunology Core, the Enteroid Core will prepare static immune cell/enteroid co-culture models to characterize the innate immune response after exposure to bacterial pathogens (i.e. EHEC, EAEC, ETEC and Shigella). The co-culture model will be developed to feature various types of immune cells including macrophages, granulocytes, and dendritic cells.
