Theme: Discovery of insect-innate immune system and Toll receptor

Innate immunity is an essential host-defense system, which participates in the elimination of microbes from the body. The molecular mechanism of the innate immune system, especially the way of recognition of microbes, had been uncovered for a long time. Dr. Jules A. Hoffmann and his colleagues discovered that Drosophila Toll gene plays essential roles in innate immunity by using genetic approaches. Drosophila Toll functions as a sensor for microbes and activates intracellular signaling pathways, thereby inducing anti-microbial peptides. Their discovery is a breakthrough for the investigation of innate immune system of mammals, and leads discovery of mammalian Toll like receptor and role of their anti-microbial functions. Their findings are also contributes to the understanding of human immune systems and used for the development of adjuvant for vaccines and new anti-viral agents.

Theme:Elucidation of molecular mechanisms of innate immune response for microbes

Immune systems are classified into two subsystems: the innate and adaptive immunity. Molecular mechanisms of innate immune responses had not been well understood, in contrast to microbe recognition by T/B cell receptors on lymphocytes in adaptive immunity. Dr. Shizuo Akira extended the study on Toll like receptor(TLR) which had been identified as a molecule involved in innate immunity of fruit fly. Dr. Akira established various TLR knock out mice, and revealed roles of TLR in innate immunity, including identification of microbe molecules corresponding to each TLR, downstream TLR signalings, and TLR-regulated immune responses. Furthermore, by identifying microbe sensor mechanisms other than TLR, Dr Akira made a great contribution for elucidation of molecular mechanisms of innate immunity. These results may lead to the further understanding on immunopathology of various diseases and development of strategies to regulate immune responses. The Keio University Medical Science Fund praises Dr. Shizuo Akira's achievement by awarding him the 2010 Keio Medical Science Prize.
