How the sleeping sickness parasite's RNA shape controls its life-stage changes
Role of RNA structure in developmental RNA editing regulation in trypanosomes
Researchers are looking at how the sleeping sickness parasite's RNA folds to change its genes, aiming to uncover targets that could help people with African sleeping sickness.

What this research studies
If you or a loved one has sleeping sickness, this team is studying the parasite's RNA to understand how it changes between the insect and human stages. In the lab they make parasite RNAs, probe their shapes with chemicals and read them with sequencing (DMS-MaPseq) to see where editing happens. They also study parasite proteins that bind RNA to turn editing on or off at early checkpoints. Together these methods aim to map the molecular switches the parasite uses to adapt to humans or insects.
Who could benefit from this research
Good fit: People affected by African trypanosomiasis (sleeping sickness) or those at high risk in endemic regions could be future candidates for trials or interventions that arise from this research.
Not a fit: People without African sleeping sickness, including those with unrelated illnesses or with Chagas disease caused by a different parasite, are unlikely to see direct benefit from this laboratory-focused project.
Why it matters
Potential benefit: If successful, this work could reveal parasite-specific RNA structures or proteins that become new targets for drugs or diagnostics for African sleeping sickness.
How similar studies have performed: Related molecular mapping and chemical-probing methods have worked in other systems and initial data exist, but applying these approaches to developmental RNA editing in Trypanosoma brucei is relatively new.
