Constitutive expression of P25
This BioBricks permit the expression of the protein P25.
The ookinete (plasmodium state in mosquito's gut) has been intensively studied by scientists, looking for an ideal transmission-blocking vaccine target. IGEM EPFL team's interest goes toward the ookinete surface membrane proteins Pfs25 and Pfs28. In fact, it has been shown that the binding of specific antibodies to these surface proteins was fatal to more than 99% of the parasites [http://www.nature.com/emboj/journal/v20/n15/full/7593895a.html 2]. Indeed, P25 and P28 seem to be essential to the ookinete survival, the crossing of the midgut epithelium and its transformation into an oocyst.
The team decided to design Asaia to express a soluble form of these 2 P-proteins. It could seems contra-intuitive to provide more of these proteins (by expression in Asaia) that are very important for the parasite survival, migration, and development. But our hypothesis is that adding a lot of these proteins in a soluble form will compete with the parasite surface protein and prevent the interaction necessary to its transmission. Because the functions of P25 and P28 are redundant, both proteins need to be inhibited or outcompeted to efficiently block the malaria transmission.
