Transcriptome analysis of HLA-DR(+) HSPCs and HLA-DR(-) HSPCs in aplastic anemia patients

HLA-DR-lacking HSPCs [HLA-DR(-) HSPCs] were detected in aplastic anemia (AA) patients with HLA-DR15. HLA-DR(-) HSPCs may evade the attack by CD4+ T-cells recognizing the autoantigen presented by HLA-DR15. The goal of this study is to clarify the immune escape mechanisms from antigen-specific T-cells by comparing the trranscriptome profile of HLA-DR(+) HSPCs and HLA-DR(-) HSPCs. Examination of HLA-DR(+) HSPCs and HLA-DR(-) HSPCs from 3 patients
