妊娠中のN-アセチルシステインが母体の高脂肪食への曝露後の神経、感情、代謝機能障害に対する性依存的予防効果をマウスで確認

**母体の肥満と子どもの神経精神障害リスクの関連性に関する研究**

母体の肥満が子どもにおける神経精神障害のリスクを高める明確な関連性が示されていますが、その背後にあるメカニズムは十分に理解されていません。私たちは、母体の高脂肪食(mHFD)がストレッサーとして作用し、グルココルチコイドを増加させ、赤色酸化還元バランスを変化させ、辺縁系の神経可塑性を妨げると仮定しました。このような持続的な影響は、成人の子どもにおける感情的および認知的プロファイル、神経内分泌反応、代謝および赤色酸化還元の恒常性を損なう可能性があります。私たちはマウスモデルと、誘導性多能性幹細胞(iPSCs)から派生したヒト神経細胞を用いた翻訳的細胞モデルを利用して、mHFDが神経発達に与える影響を評価し、抗酸化剤N-アセチルシステイン(NAC)が提供する保護効果をテストしました。私たちのアプローチは、行動および代謝の表現型評価、生化学的アッセイ、形態学的評価、標的遺伝子発現分析を組み合わせたものです。

結果は、NACの出生前投与がmHFDを摂取したマウスの子どもにおいて、不安様行動やリスクテイキング行動、認知障害、代謝の変化を防いだことを示しています。特に雌マウスにおいて顕著でした。これらの変化は、BDNFなどの神経可塑性に関与する遺伝子の海馬におけるダウンレギュレーションを伴っていました。ヒト神経細胞を用いたin vitro実験では、NACによる前処理がグルココルチコイドの神経可塑性に対する悪影響をBDNFを介したメカニズムで救済しました。mHFDに対するNACの保護効果は、赤色酸化還元状態の再バランスが神経発達に対する早期の逆境の悪影響を緩和するための全体的な戦略として利用できる可能性を示唆しています。

精神障害は深刻な社会的および経済的影響を及ぼし、世界的な疾病負担に寄与しています。現在の研究は、新たな介入ターゲットの特定に焦点を当てています。この文脈において、酸化ストレスは多くの精神障害の病態生理における中心的な要因として浮上しており、新しい薬理学的アプローチの有望な道を提供しています。逆境的な幼少期の経験は、脳の発達軌道を形成する生物学的痕跡として埋め込まれる可能性があり、最終的には神経発達および精神障害に対する脆弱性を高めることになります。母体の心理的ストレスの影響はよく知られていますが、バランスの取れていない食習慣などの他の環境的課題も子どものメンタルヘルスのリスク要因として浮上しています。特に、母体の肥満は神経精神障害や気分障害、認知障害のリスクを直接的に高めることが示されており、赤色酸化還元の不均衡や視床下部-下垂体-副腎(HPA)軸の過剰な活性化と関連しており、高いグルココルチコイドレベルや炎症の増加を引き起こします。このような反応の総合的な結果は、子どもにおいて深刻な短期的および長期的な悪影響をもたらす可能性があります。
