antigen specific in vivo killing assay using cfse labeled target cells

カルボキシフルオレセインジアセテートスクシンイミジルエステル（CFSE）を容易かつ迅速に生体内での調査のための関心の細胞集団を標識するために使用することができます。この標識は、古典的な増殖と移動を研究するために使用されています。ここで紹介した方法では、我々は、エピトープの特定のCFSE標識した標的細胞を4-6の生存と殺害を見に養子移入した後にタイムラインを短縮している。その量は、誤解を招く可能性があるとしてCD8 + T細胞クローンの特定の殺害のレベルは、応答の質を示すことができます。特定のCD8 + T細胞はサイトカイン産生と7,8を殺すの低下と時間をかけて機能的に枯渇することができます。また、特定のCD8 + T細胞クローンは、異なるTCRの特異性9と同様に他人を殺すしないことがあります。効果的な細胞性免疫（CMI）の場合、抗原はT細胞の応答の適切な数字だけでなく、機能的に堅牢な応答性T細胞だけを作り出すことを識別する必要があります。ここでは、BALB / cマウスに2つのペプチド特異的T細胞クローンのパーセントの細胞特異的殺傷を評価する。
