Outline of Final Research Achievements

The effects of insulin-like growth factor type (IGF-2), which expression is enhanced in the brain of neonatal white matter injury (NWMI), on differentiation of oligodendrocyte progenitor cells (OPCs) in vitro and on the ability of OPCs to differentiate in vivo were investigated, aiming to clarify the mechanism of differentiation of grafted OPCs from overcoming inhibitory action of the brain in a NWMI model. We revealed that the treatment of IGF-2 alone can induce to differentiate OPCs to mature oligodendrocytes. We also reported that overcoming inhibitory effect in the brain of NWMI is rather important than trophic effect by IGF-2 to promote maturation of grafted OPCs in vivo: less number of grafted OPCs were differentiated to CC-1-positive mature OLs in a NWMI model compared to sham-operated control.

Academic Significance and Societal Importance of the Research Achievements

新生児低酸素虚血性白質傷害(NWMI)の脳内に発現増加するインスリン様成長因子2型(IGF-2)が、オリゴデンドロサイト前駆細胞(OPC)の分化を促進することを証明した。またNWMI脳内ではIGF-2の作用よりも脳内の分化抑制作用が強いことがin vivo実験から明らかになり、移植されたOPCの脳内における成長を促進させるためには、この抑制機構の解明が優先される課題であることが明らかになった。ラットを用いた本研究からの課題を動物実験レベルから解明し、ヒトへの応用に繋げることを目指していきたい。また、免疫用製剤の存在化における研究を展開し、更なる治療効果の展開へと繋げたい。
