中脳ドーパミン作動性ニューロンは、中枢神経系におけるドーパミンの主な供給源である。これら3つのグループに分割され、黒質緻密部（SNpc）、腹側被蓋野（VTA）及びretrorubralフィールド（RRF）10、11。 SNpcとVTAのニューロンは、そのような感情、動機と運動行動の制御などの機能に関与する主要なドーパミン作動性経路に上昇、中間皮質、中脳辺縁系と黒質線条体を与える。 SNpcと?...

黒質のドーパミン作動性ニューロンの損失は、緻密は、パーキンソン病（PD）、第二の最も優勢な神経変性疾患の基本的運動症状につながる様部。この中脳ニューロン集団の終焉の根本的な原因は知られていない。開発を担当し、神経生理学的特性およびmesDAニューロンの生存を調節する生化学的経路を研究するために、いくつかの細胞培養と動物モデル系が使用されている。ラットは、ドーパミン作動性細胞株1RB 3 AN 27（N27）、ヒトドーパミン作動性の神経芽細胞腫細胞株SH-SY5Y、MN9Dおよびヒトの脳細胞をLUHMESマウスドーパミン作動性のハイブリッド細胞株を含む、不死化細胞株は、生化学的および限定された機構研究1のために使用されている-5。 mesDAニューロンの特定の損失の研究のために、いくつかの神経毒をベースと遺伝モデルが6-8を開発されてきた。初代腹側中脳の文化、ドーパミン作動性ニューロンの神経細胞とシナプスのプロパティと、この一般的な疾患の病因に関与する経路を研究するための不可欠なツールを提供する。 ここでは、より高い生存性と胚あたりのカバースリップの増加収量、結果の修正が含まれている中脳ドーパミン作動性ニューロンの分離のための詳細なプロトコルを提示する。前成熟したE12.5マウス中脳（ラットにおいてE14.5）の使用は、生存性を向上させます。この年齢でのニューロンは解剖時に無傷の細胞を残している、まだ軸索を開発し、それによって大幅に生存能力を高め、ストレスを最小限にしていない。また、腹側中脳の注意深い解剖は、このプロトコルのセクション2で説明したように、さらに生存性を高めます。胚あたりのカバースリップの数を増加させるために、代替的なメッキ法は、このプロトコルのセクション4に示されている。これは、下の4カバーガラスと比較して胚当たり最大10カバーガラスの収率をもたらす標準めっき条件は、このように、実験あたりの動物の量を減らす。 軸索とdentritesの文化展示成長におけるニューロンは、シナプス結合を形成し、生細胞イメージング、免疫細胞化学的および電気生理学的研究のために、これらの培養物は適して神経細胞とシナプスマーカーの存在を明らかにする。さらに、ニューロン培養の使用は遺伝的および薬理学的操作を容易にします。 in vitroでの 2日目からの神経突起の伸長が発生研究が可能になります。また、（6週間まで）培養物の長期生存は、これらのニューロンの遅い、進行性変性を研究するのに適したものとなる。

isolation, culture and long-term maintenance of primary mesencephalic dopaminergic neurons from embryonic rodent brains

Degeneration of mesencephalic dopaminergic (mesDA) neurons is the pathological hallmark of Parkinson&#8217;s diseae. Study of the biological processes involved in physiological functions and vulnerability and death of these neurons is imparative to understanding the underlying causes and unraveling the cure for this common neurodegenerative disorder. Primary cultures of mesDA neurons provide a tool for investigation of the molecular, biochemical and electrophysiological properties, in order to understand the development, long-term survival and degeneration of these neurons during the course of disease. Here we present a detailed method for the isolation, culturing and maintenance of midbrain dopaminergic neurons from E12.5 mouse (or E14.5 rat) embryos. Optimized cell culture conditions in this protocol result in presence of axonal and dendritic projections, synaptic connections and other neuronal morphological properties, which make the cultures suitable for study of the physiological, cell biological and molecular characteristics of this neuronal population.
