Flow cytometric analysis of PBMCs.

Representative data of PBMCs from one patient with ATL, one patient with HAM/TSP, and one HTLV-I carrier. PBMCs were stained by PC5-labeled anti-CD4 (A), anti-CD8 (B), FITC-labeled anti-CD45RA, PE-labeled anti-CD62L. Naive T cells (N) were CD45RA⁺ and CD62L⁺, and memory T cells can be divided into 3 groups (M1, M2, and M3).
