| Outline of Final Research Achievements |
We examined the factors associated in immune tolerance by cytokine assay. However, ASC isolated by FACS was remained an issue, as these cells were heterogeneity cell population. Therefore, we verified whether there are cells involved in immune tolerance in the population using single cell RNA-Seq. As a result, ASC isolated by the conventionally method revealed that were consists of ten populations from genetic similarity. Furthermore, through global gene analysis, expression of a genes related in an immune tolerance were upregulated in a specific cell population X. When this cell population was co-cultured with CD3-positive T cells in LPS-supplemented medium, we confirmed differentiation of CD3 positive T cells to CD4/25/Foxp3 positive Treg was significantly increased. In addition, the signal existing between population X and CD3 positive T cells was analyzed by RNA-Seq. As a result, we identified candidate factors associated in the immune tolerance.
