Outline of Final Research Achievements

To control rabies, lethal viral zoonotic disease, experimental and pathological studies were performed, especially brain histopathology and CSF analysis were examined. It is showed that rabies viruses were eliminated from the brain and not induce lethal infection when viral neutralizing antibodies were produced in blood and CSF in high level. Further, the antigen-specific antibodies in CSF were produced in deep cervical lymph nodes, and brain dura matter might be involved in cerebral immune responses. Apolipoprotein A-1 in CSF was detected after rabies virus infection, as one of the small compositional changes in CSF.

Academic Significance and Societal Importance of the Research Achievements

狂犬病の治療法は未だ確立されておらず、ひとたび発症すると悲惨な神経症状を示して、死を待つという恐ろしい病気であるが、本病に関する研究は進展がないまま頓挫している状況にあった。本研究成果は狂犬病の原因ウイルスを体内で駆逐するための具体的な戦略を示した点において学術的意義が高く、また、その他の中枢神経系感染症や炎症性疾患への応用も期待できる成果であるため、学術的意義が高い基礎研究である。また、本病は年間5万人以上が犠牲となっている状況であり、本邦においても輸入感染症、越境感染症、バイオテロなどにより発生リスクが無視できないため、その制圧に貢献する知見を提供した点において社会的意義も大きい。
