Outline of Research at the Start

授乳中の母親ならびに乳児の健康を考える上で,母親の食事は,母乳の質に影響し,母子の健康状態を左右する。また,早期ライフステージにおける栄養環境要因と,子どもの生涯にわたる健康への影響が注目されている。本研究では,母乳中の生理活性脂質(脂質メディエーター)に着目し,「脂質の質 = 脂質メディエーターバランス」が母子の健康に及ぼす影響を調査することで,母乳の脂質の新しい栄養生理学的な意義を示す。加えて,母親の摂取する「脂質の質」の改善が,母から子へ,また,母体そのものへおよぼす効果を明らかにすることで,授乳婦の摂取する「脂質の質」の重要性を提唱し,母子の生涯にわたる健康維持に貢献する。

Outline of Final Research Achievements

A comparison of human milk and cow milk by lipidomic analysis showed that human milk had a higher content of unsaturated fatty acids, similar proportions of ω3 and ω6 polyunsaturated fatty acids (PUFAs), and a higher proportion of specialized pro-resolving mediators (SPM), indicating a superior lipid composition compared to cow milk. Lipidomic analysis of mouse milk showed the milk composition was similar to that of human milk. Then we made screening of mouse phospholipase A2 isozymes related to mammary gland development and identified some kind of PLA2. The recombinant enzyme was prepared and we analyzed the enzyme activities on some phospholipids and clarified substrate affinity. The PLA2 exhibited to release PUFAs from the phospholipid sn-2 position, indicating that the enzyme may contribute to the milk lipid composition.

Academic Significance and Societal Importance of the Research Achievements

乳汁栄養の質は,乳児の将来の肥満や生活習慣病に深く関係すると考えられる。乳児期栄養のエネルギー比率50%を担う脂質については,エネルギー源として重要であることや神経や網膜の発達に必須の多価不飽和脂肪酸が多く含まれること以外に,その意義についてはあまり分かっていない。本研究では,母乳の「脂質の質」とそれを決定する酵素を調査し,母乳の脂質成分組成が牛乳と比較しても,大変優れていることを見出した。本研究成果は,母乳の新しい栄養生理学的な意義に加え,母乳育児の新たな意義を示すものである。さらに,この優れた母乳の脂質成分組成の情報は,人工栄養(乳児用調製乳)の改良へも貢献できるかもしれない。
