The high abundance of CD16+CD38+CD4+CXCR3+CCR6+ naive T cells, HLA-DR+CD38+IFNγ+TNF+ EM T cells, HLA-DR+IFNγ+ naive B cells, and CD14++CD11C+IFNγ+IL1B+ monocytes were considered to be cellular immune characteristics for the patients with CDa. Here, CCR6 is linked to congenital dyserythropoietic anemia.
