The research has identified a molecule in Plasmodium falciparum, called PfSET10 that plays a role in the genetic control of the membrane protein PfEMP1 (Plasmodium falciparum erythrocyte membrane protein 1). PfEMP1 is a surface membrane protein which enables the parasite to adhere to the lining of the host blood vessels, and has a variant genetic code ensuring a percentage of the parasites remain undetected.

The identification of PfSET10 and it’s specific localisation to the gene expression site for PfEMP1 variation, is a step towards unravelling exactly how P. falciparum is able to hide from the immune system.
