Parasitology/Echinococcus (Brehm lab)

Parasitic flatworms (cestodes and trematodes) are a major cause of human disease world-wide. Our group investigates host-parasite interaction mechanisms as well as parasite molecular-, cell-, and developmental biology using the cestode model system Echinococcus multilocularis. The metacestode larval stage of this tapeworm causes the lethal disease alveolar echinococcosis (AE) through extensive cancer-like growth within the host liver, accompanied by suppression of the host immune system. AE treatment causes enormous problems since only few cases are amenable to surgical treatment and many patients have to undergo life-long chemotherapy. Our group has previously characterized the E. multilocularis genome, showed that parasite growth is decisively driven by totipotent somatic stem cells, and demonstrated that formation of the unusual metacestode stage is a result of the modification of the parasite’s body axes. The proliferation dynamics of the Echinococcus stem cell population and cellular signalling systems governing larval stage differentiation are at the focus of our research interests. We also extensively study parasite genomics/transcriptomics and engage in the development of forward genetic methodology for flatworm parasites. Finally, immune-modulatory activities of the Echinococcus metacestode stage and the development of novel chemotherapeutics against the disease are investigated.
