Outline of Research at the Start

遺伝的にもヒトに極めて近いと考えられる非ヒト霊長類カニクイザルより得られる血液、組織由来検体を用いて、様々な年齢の個体を対象として加齢に伴う免疫老化現象を、特にT細胞を中心とする獲得免疫反応の変化に着目して分子レベルで解析する。その情報をもとに、免疫老化現象の実態を個体レベルで解明することを目指し、将来的には年齢に応じた高齢者用新規ワクチン開発や免疫療法の開発に繋げる研究基盤を構築することを目的とする。

Outline of Final Research Achievements

Immunosenescence is known as the process by which the immune system changes with age, and it is known to be associated with increasing the risks of cancers and infectious diseases in elderly individuals. However, the true nature of immunosenescence remains to be elucidated. In this study, we conducted the use of cynomolgus macaques with a wide range of age groups in the same animal facility and examined the qualitative and quantitative changes of each immune cell in these cynomolgus macaques. We found that (1) telomere lengths and telomerase activities of hematopoietic progenitor cells were declined in aged cynomolgus macaques, (2) this phenotype is inherited by especially naive T cells, (3) the number of naive T cells was decreased like human beings and (4) the production of some inflammatory cytokines by effector memory T cells was enhanced.

Academic Significance and Societal Importance of the Research Achievements

加齢による免疫系への影響は、様々な免疫担当細胞の活性化状態やサイトカイン産生の変化といった質的変化や量的変化など、多岐に渡る可能性が示唆されている。このような複雑な現象を理解するためには、ヒト臨床検体と個体レベルでの解析が必要である。これまで、免疫老化研究を対象とする実験動物モデルは確立されていなかったが、本研究によりカニクイザルの有用性を示すことに成功した。今後さらにカニクイザルを用いた詳細な解析を行うことで、免疫老化をふまえた新規ワクチンの開発や免疫療法の確立が期待できる。
