Intracellular metabolite concentrations in T. brucei exposed to oxidative stress

The SilicoTryp project aims at the creation of a “Silicon Trypanosome”, a comprehensive, experiment-based, multi-scale mathematical model of trypanosome physiology.
Trypanosomes are blood-stream parasites transmitted by tsetse flies; they cause African sleeping sickness in humans and livestock. Currently available drugs have severe side effects, and the parasites are rapidly developing resistance.
In this project, we collect a wide range of new experimental data on the parasite in its various

The aims of this investigation is to quantify metabolites associated with pathways involved in stress responses for parameterising models of oxidative stress metabolism; the measurement of metabolic fluxes of metabolites of interest with intracellular concentrations

In addition to the highly targeted quantification of metabolites already known to play major roles in oxidative stress, to provide data directly compatible with current models, we will also take an untargeted metabolomics approach. This will enable us to identify other areas of the metabolome influenced by, or influencing, oxidative stress and will allow us to compare changes in each of the stress-inducing stimuli. We have recently pioneered untargeted metabolite profiling of T. brucei using
