Flatworms include more than 44,000 parasites, many of which are pathogenic to humans or livestock, with flukes, tapeworms, and hookworms as notorious representative species. They typically transmit through multiple hosts using several drastically different body plans specialized for infecting and reproducing within each host. Although flatworms’ complex life cycles were established over a century ago, little is known about the cells and genes they use to optimize their transmission potential, thereby limiting our ability to develop effective therapeutic and preventive strategies. We aim to develop a comprehensive cellular and molecular understanding of the stereotypical life cycle of a blood fluke, Schistosoma mansoni, and identify novel targets to block it. Schistosomes cause one of the most prevalent but neglected infectious diseases, schistosomiasis. With over 250 million people infected and a further 800 million at risk of infection, schistosomiasis imposes a global socioeconomic burden comparable to that of tuberculosis, HIV/AIDS, and malaria. This project will use novel single-cell technologies to build a schistosome "cell atlas", and map the developmental states of their stem cells as they produce all other cell types in the schistosome body plans.
