Gunnar Mair LabMajor Interests
The spread of malaria depends on the transmission of Plasmodium parasites from the human host to the mosquito vector and relies on fertilization and development of zygotes into the motile ookinete form.
During this 24-hour window the parasite encounters drastic changes in environmental conditions, and relies on timely and appropriate control of protein expression to undergo development. Our lab is interested in the molecular mechanisms that allow the parasite to respond to these environmental and developmental changes. Both transcriptional and post-transcriptional mechanisms have been shown to play key roles during this crucial time in the parasite’s life cycle. Using molecular and cell biology, as well as biochemistry, microarray profiling and proteomics techniques, our aim is to understand how these diverse mechanisms are integrated to allow the parasite to quickly and successfully perform these required changes with an ultimate goal to identify novel transmission blocking strategies.
