Abstract
Description
したがって、ADを得るのに必要な3〜6週間の時間をモノアミンのシナプスレベルの増加と相関させることは困難であり、これは製品の最初の投与と同時に起こる。半世紀近く、うつ病の病因とその治療法に関する仮説の数は増え続けている。
− 宿主細胞を本発明による核酸でトランスフェクトすること、または本発明のベクターで宿主細胞を形質転換する工程;
− 本発明によるペプチドの発現を可能にする条件下で前記宿主細胞を培養する工程;及び
− 前記ペプチドを回収する工程。
スパジン類似体およびスパジンの効果を測定するすべての実験は、TREK−1チャネル、hTREK−1/HEK293で安定的にトランスフェクトされたβTC3またはLNCaPまたはHEK293細胞に対して行われた。hTREK−1/HEK293細胞株は研究室で調製された[21]。これらの細胞はまたレポーター遺伝子:それらの可視化を可能にするE−グリーン蛍光タンパク質(EGFP)を発現する。
強制泳動試験(FST)
物質の抗うつ活性を決定するために古典的行動試験が開発された(Nestier E.J. et al、2002、Cryan J. and Holmes A.、2005)[22〜23]。本発明のスパジン類似体の効果を、本発明のスパジン類似体が溶解されている食塩水の効果およびスパジンの効果と比較した。使用したマウス系統は、C57BI/6J系統であった。
学習した甘受または学習した無力感は、動物に甘受状態を誘導するための電気ショックの反復投与に基づくモデルである。確かに、避けられない電気ショックを受けた動物はそれらを受けることを甘受し、逃げようとしないことが示されている(SeligmanおよびBeagley、ラットJ Comp Physiol Psychol 88、534-541、1975)[24]。
免疫組織化学による神経発生の研究
BrdU(5−ブロモ−2’−デオキシウリジン)は、チミジンに類似の合成ヌクレオシドである。分裂中の細胞のS期(間期中の染色体複製)中のDNA複製中に取り込まれる。 BrdUの注射は、免疫学的標識によって分析されるべき組織の分割における細胞を視覚化することを可能にする。本研究では、マウスの海馬神経発生を、スパジンまたは異なる類似体での治療後に評価した。
妊娠した雌C57Bl/6Jマウス(20〜25g、Janvier Labs、St Berthevin、フランス)を、30%酸素および70%亜酸化窒素と混合した2%イソフルランの吸入によって麻酔し、次いで屠殺した。胚(E14)を取り出し、大脳皮質を1%グルコースを含有するPBS中で解剖した。ニューロンは、Brewer and Torricelli、2007[26]に記載されているように、大脳皮質から機械的解離によって調製した。解離したニューロンをポリ−L−リジン処理プレートに分配し、37℃で2%B27(Invitrogen、Fisher Scientific、Illkirch、フランス)および50μg / mlゲンタマイシン(Sigma、フランス)を含有する神経基礎培地中で最大10日間培養した。 5%CO2下での温度。
