Differential infection of EBV into lymphocyte subpopulations between EBV-related disorders.

PBMNCs from patients with EBV-HLH (left column), CAEBV (center column), or acute phase IM (right column) were separated into CD4⁺ T cells, CD8⁺ T cells, CD16⁺ NK cells, and CD20⁺ B cells the same as in Figure 2. Frequency of each lymphocyte subpopulation was estimated by EBER-1 ISH.
