Representative PrimeFlow assay data showed EBV-infected hematologic cells in CAEBV. (A) EBV-infected cells are identified in CD3⁺ T cells, CD19⁺ B cells, CD56⁺ NK cells, CD14⁺ monocytes, and CD15⁺ neutrophils from PB samples of the patients with CAEBV (subjects 1 and 2). (B) EBV-infected cells are identified in CD3⁺ T cells, CD19⁺ B cells, CD56⁺ NK cells, CD14⁺ monocytes, and CD15⁺ neutrophils from BM samples of the patients with CAEBV (subjects 1 and 2). Refer to supplemental Figure 3A for megakaryocytes and erythrocytes. In each panel, the top row shows the data from subject 1, whereas the bottom row shows the data from subject 2. Both patients were diagnosed as CAEBV, and the EBV-infected cells were found in almost all hematologic cell types. SSC-A, side scatter-area.
