Outline of Final Research Achievements |
After isolation of human myeloid-derived suppressor cells (CD11b+CD14-CD33+ cells) with magnetic beads, we have conducted the experiment evaluating the changes in mRNA and miRNA expression in cell culture study with LPS application and different glucose concentration. We have conducted the comprehensive analysis of mRNA and miRNA by next generation sequencing with outsourcing. Further, we have conducted the pathway analysis using RNAseq data.

Academic Significance and Societal Importance of the Research Achievements |
骨髄由来抑制細胞(MDSCs)は多くの免疫抑制をもたらす細胞群の中で,癌患者における免疫抑制の主要な部分を担うとして重要視されてきた。MDSCは癌や炎症によって,本来骨髄中に存在する細胞が癌局所や全身の血液循環に出現する未熟な細胞群です。もともと均一でない細胞群とされますが,この中にはgranulocytic MDSCとmonocytic MDSCが存在する。 免疫抑制が近年、敗血症病態における骨髄由来抑制細胞(MDSCs)の免疫抑制作用に注目がされているが、次世代シーケンサーを用いて、トランスクリプトーム解析(mRNA, miRNA)を、網羅的に解析した研究は無い。
