The protozoan pathogen, Trypanosoma brucei, is the causative agent of sleeping sickness in humans and nagana in livestock in sub-Saharan Africa. T. brucei cycles between tsetse fly and mammalian hosts, and it is adapted to survive in diverse host tissues. Variant Surface Glycoprotein (VSG) plays a key role in immune evasion in the mammalian host. The VSG membrane anchor requires two myristates, 14-carbon saturated fatty acids (FAs) that are scarce in the host. T. brucei can synthesize FAs de novo, but also readily takes up exogenous FAs, despite lacking homologs to fatty acid uptake proteins found in other …

Trypanosoma brucei is an extracellular eukaryotic parasite that causes sleeping sickness in humans and cattle. As an extracellular parasite, T. brucei relies on the host’s nutrients to satisfy its growth requirements. The parasite is unusual because it does not uptake most of the host’s lipid species. Instead, T. brucei prefers to perform de novo synthesis of most lipid species. One of the lipid species that T. brucei can both uptake and synthesize is fatty acids. In my thesis work, I investigated the dynamics of fatty acid uptake, metabolism, and utilization of T. brucei. My work starts by determining the …
