Outline of Final Research Achievements |
The aim of this study is to clarify the role of immune receptors with inter- and intraspecies diversity in infectious diseases. In the process of search for interaction between pathogens and host immune receptors, it was found that inhibitory receptor LILRB1 recognized RIFINs expressed on P. falciparum-infected red blood cells. RIFINs inhibited activation of LILRB1-expressing B cells and natural killer (NK) cells. Furthermore, P. falciparum-infected erythrocytes isolated from patients with severe malaria were more likely to interact with LILRB1 than erythrocytes from patients with non-severe malaria, suggesting that LILRB1-RIFIN interaction may be involved in the development of severe malaria.
