Outline of Final Research Achievements

This study screened human proteins interacting with infected erythrocyte surface antigens (Rifin) with a human protein library synthesized in the wheat germ cell-free system (WGCFS). As a result, a human protein that interacts with TLRs bound to Rifins. This human protein has 8 paralogs in the human genome, all named h-RIP1 to 8. The eight h-RIP proteins were successfully synthesized with WGCFS. By SPR single kinetics assay, the h-RIPs bound the Rifin with KD value approximately 1 x 10-7 M.

Academic Significance and Societal Importance of the Research Achievements

熱帯熱マラリア原虫は様々な原虫タンパク質を感染赤血球の表面に表出することで血管内皮細胞の表面に結合したり、免疫細胞と相互作用するなどして宿主の様々なレベルの免疫機構から逃れることが知られている。本研究ではそのような感染赤血球表面の原虫タンパク質が相互作用する自然免疫に関わる分子を新たに同定した。マラリア原虫が宿主免疫から逃れる機構の一端を明らかにすることができた。
