I started my PhD in the Cell Surface Signalling Group in 2013 and have since been investigating how Plasmodium falciparum parasites, the causative agent of the most severe
form of human malaria, interact with their human host.
Both manuscripts detail the role of the same AP2 - G transcriptional regulator with remarkably similar findings — despite the different groups» having worked with two highly diverged malaria parasites: Plasmodium falciparum, which causes the most severe
form of human malaria and Plasmodium berghei, a commonly used model parasite infecting rodents.
