Because of the species-specificity of many human hepatropic pathogens, these engineered systems have been essential tools for biologic discovery and therapeutic agent development in the context of liver-dependent infectious diseases. Although improvement of existing models is always beneficial, and the addition of a robust immune component is a particular need, at present, considerable progress has been made using this combination of research platforms. We highlight advances in the study of hepatitis B and C viruses and malaria-causing Plasmodium falciparum and Plasmodium vivax parasites, and underscore the importance of pairing the most appropriate model system and readout modality with the particular experimental question at hand, without always requiring a platform that recapitulates human physiology in its entirety.en-USLiverLiver Models3Din vitroin vivoHepatotropicPathogenHBVHCVMalariaFalciparumVivax2D, 2-dimensional3D, 3-dimensionalEBOV, Ebola virusHBV, hepatitis B virusHBC, hepatitis C virusHLC, hepatocyte-like cellsiHLC, induced pluripotent stem cell–derived hepatocyte-like cellsLASV, Lassa virusMPCC, micropatterned coculture systemPCR, polymerase chain reactionSACC, self-assembling cocultureJournal Article2018-02-2610.1016/j.jcmgh.2017.11.005
