Research Abstract

本研究は、自己免疫疾患の病態への関与が示唆されているIL-21のT細胞における産生制御機構を明らかにすることを目的とした。可溶化IL-21レセプターを用いた細胞内IL-21染色法を確立し、CD4陽性T細胞におけるIL-21産生制御機構を解析したところ、IL-21産生CD4陽性T細胞とTh17細胞は異なる細胞分画であること、IL-21産生CD4陽性T細胞とTh17細胞は、共にIL-6或はIL-21を分化誘導因子として必要とするが、TGF-βとIL-2に対する反応性は異なることが明らかとなった。これらの結果は、IL-21産生CD4陽性T細胞とTh17細胞は、自己免疫病態において異なる役割を果たしている可能性を示唆している。
