Hypothesis
To identify new transmission blocking vaccine candidates by defining the microneme content from ookinetes of Plasmodium berghei.
Conclusion
The study identified over 50 novel candidate proteins essential for malaria transmission to mosquitoes, with one candidate, akratin, showing dual roles in gametogenesis and ookinete migration.
Supporting Evidence
- Over 50 novel candidate proteins were identified that may play essential roles in malaria transmission.
- Akratin was shown to be essential for male gametogenesis and ookinete migration.
- Mutation of a putative trafficking motif in akratin affected ookinete to oocyst transition.
Takeaway
Scientists found new proteins in malaria parasites that help them spread to mosquitoes, which could lead to new ways to stop malaria.
Methodology
The study used APEX2-mediated rapid proximity-dependent biotinylation to identify proteins in the micronemes of Plasmodium berghei ookinetes.
Limitations
The study did not provide co-localization proof that akratin is in the micronemes, which are not thought to be present in gametocytes.
