Outline of Annual Research Achievements

バベシアは赤血球のみに侵入して、貧血などの病原性を引き起こす。このため、バベシア表面の分子(リガンド)は赤血球膜上の特異的レセプターを認識し、赤血球に接着し侵入可能となる。これまで、赤血球膜上グリコフォリンA およびBがバベシアのレセプターで、このレセプターを介して赤血球に侵入する事が明らかになっている。したがって、このレセプターの機能を消失させれば、バベシアの赤血球への侵入を阻止する事が可能となると考えられる。そこで、本研究では、siRNAにより赤血球膜上のグリコフォリンの遺伝子サイレイシングによりレセプター機能を消失させる事を研究の目標とした。当該年度に得られた成果は下記の通りである。①ウシ、ウマ、イヌのグリコフォリンsiRNA結合PA-DHPAは培養バベシア原虫の増殖を顕著に阻止した。②siRNA結合GYPC-DNPsにより赤血球上のGYPレセプターが機能不全になり、B. bovis と B. divergensのメロゾイト虫体の赤血球への侵入がそれぞれ80%、40%が阻止された。③siRNA結合GPPA-DNPsはマウスにおけるB. microti の増殖を抑制した。
