The Role of NK Cells in the Control of Viral Infection in HTLV-1 Carriers

Figure 1

Strategy developed to characterize NK-like cells from HTLV-1-infected subjects and seronegative individuals. Peripheral blood mononuclear cells (PBMCs) were stained with monoclonal antibodies for characterization of NK-like cells by flow cytometry. Lymphoid cells were selected by size (SSC) and granularity (FSC) (a), and then cells were characterized by CD56⁺CD3^- (b), CD56⁺CD16⁺ (c), CD56⁺ cells (d), and CD56^dim and CD56^bright (e).
