The viral DNA load in the sorted cells of the patient with NK/T lymphoma was located in the B cells (1.2 × 104 copies/105 cells), whereas the CD8 positive T cells (1.6 × 104 copies/105 cells) and monocytes (2.0 × 104 copies/105 cells), had high levels of EBV DNA as well. Here, CD8A is linked to lymphoma.
