The Tetrahymena system as an innovative approach to malaria vaccine antigen expression

Objective

This STREP, coordinated and lead by an SME, will focus on the development of new malaria vaccine candidates with the aim of taking at least one product to the stage of pilot scale up at GLP standard. Products showing most promise, once expressed in the Tetrahymena system, will proceed to antigen testing in vitro and in vivo, to assess their structure and antigenic integrity. We expect to be able to produce at least one product for lead optimisation, safety and toxicology testing according to GLP standards. Combining the expertise of the two university malaria research laboratories with the novel Ciliate-based expression system in development by the SME, will generate several recombinant Tetrahymena thermophila expressing malaria antigens based primarily upon MSP-1 and the var2CSA genes of Plasmodium falciparum. To utilise the capabilities of the participants to the greatest efficiency, (both from the SME and two leading European universities), this STREP will consist of five workpackages: WP1: Project Management WP2: Development of transgenic Tetrahymena expressing MSP-1 Block 2 antigens WP3: Development of transgenic Tetrahymena expressing var2 CSA antigens WP4: GLP pilot scale production and purification of antigens expressed in Tetrahymena WP5: Testing and validation of candidate vaccines This STREP application, coordinated by Cilian AG, will provide an expression platform that is easily able to combine antigens, to develop combinatorial vaccines that may be more promising than the vaccines currently in development. Ciliate-based expression of Plasmodium falciparum proteins in secreted, membrane bound or cytosolic forms will complement the work being done as part of other larger European malaria vaccine development projects.
