Outline of Final Research Achievements |
Malaria and leishmaniasis are vector-borne diseases caused by blood-sucking insects transmitting Plasmodium and Leishmania parasites. Although the vectors of the parasites are defined, the determinants for vector specificity are unkown. We focused on the midgut of their vectors of which are important to develop and to acquire the infectivity with human for their parasites. We attempted to identify the determinant for infection using sugars possessing biological functions. This study showed that 1) a rare-sugar, D-allose, has the inhibitory effect for Plasmodium parasite development in the midgut. 2) A factor participating in the inhibition was identified.

Academic Significance and Societal Importance of the Research Achievements |
本研究課題は、生体調節機能をもつ糖類を利用して、病原体発育・ヒト感染性獲得の成否を決定づける因子を明らかにすることである。数多くの糖類は、機能性食品や健康食品への応用研究が盛んに行われている。しかし、ベクターの病原体媒介のメカニズムを明らかにすることを目的とした研究は国内外問わず行われていない。本研究課題の成果は、病原体媒介の謎に迫るだけでなく、希少糖を始めとした糖類を用いた新たなベクターコントロール法の創出に繋がるものと考えている。
