Research summary

African trypanosome parasites cause both human and animal wasting diseases, particularly across areas of sub-Saharan Africa where they are spread by biting tsetse flies. The WHO estimates 65 million people are at risk of infection, as are the agricultural animals needed for economic wellbeing.

During the life cycle, trypanosomes transition between replicating and non-replicating forms, each specialised to infect and colonise different tissues in the mammalian and tsetse fly hosts. Understanding how the parasites differentiate between these distinct forms is necessary for the development of new strategies to treat infection and block transmission.

We are using single cell transcriptomics to study gene expression change during the life cycle of Trypanosoma brucei. Single cell transcriptomics allows mixed populations of cells to be investigated without the need for prior sorting or cultivation. Using this state-of-the-art sequencing technology, bioinformatic analysis and genetic manipulation, we aim to dissect each transition stage and identify key genes in the process.
