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

Figure 2

Strategy developed to characterize CD56⁺CD3⁺ NKT cells from HTLV-1-infected subjects and seronegative individuals. Peripheral blood mononuclear cells (PBMCs) were stained with monoclonal antibodies for characterization of CD56⁺CD3⁺ NKT cells by flow cytometry. Lymphoid cells were selected by size (SSC) and granularity (FSC) (A), and then NKT cells were gated from a CD3⁺ plot, classified as CD56⁺CD3⁺(CD16^+/-).
