Outline of Final Research Achievements

Single-cell RNA-seq (scRNAseq) has made it possible to estimate cell types such as CD4-positive T cells, regulatory T cells, NK cells, and B cells, and to measure the comprehensive gene expression of individual cells without prior information on the target molecules. The present study was conducted to investigate the effect of cedar antigens on the gene expression of cedar cells. In this study, scRNAseq of peripheral blood mononuclear cells was performed on patients treated with sublingual immunotherapy against Japanese cedar pollen before and after the start of treatment, and cell types and gene expression related to treatment response were examined. In the comparison of pre- and post-treatment, we detected several genes whose expression levels were statistically significantly changed in response to treatment.
