Expression of CCR8 in JPX9 T-cells and peripheral blood mononuclear cells (PBMCs) from HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) patients. The levels of CCR8 expression in HTLV-1-infected and -uninfected human T-cell lines as well as in PBMCs derived from HAM/TSP patients were examined using flow cytometry. a. CCR8 was expressed in both HTLV-1-infected and -uninfected T-cell lines, but the mean fluorescence intensities (MFIs) of these T-cell lines were not associated with the status of HTLV-1 infection. b. The MFI of CCR8 was higher in the Tax-positive fraction compared to the Tax-negative fraction in Tax-induced JPX-9 cells c. The MFI of CCR8 was higher in Tax-positive PBMCs than Tax-negative PBMCs derived from HAM/TSP patients
