Figure Lengend Snippet: Functional characterization of murine CD127 + NK cells. ( a ) Cytotoxic activity of sorted, freshly isolated CD127 + and CD127 − NK cells from the spleen and lymph nodes of adult C57BL/6 mice ( n = 5) was assessed against YAC-1 target cells using a 51 Cr-release assay at the indicated effector-to-target (E/T) ratios. CD127 + NK cells exhibited measurable cytotoxic activity; however, their lytic capacity was significantly lower than that of CD127 − NK cells at multiple E/T ratios. ( b ) Intracellular IFN-γ production by CD127 + and CD127 − NK cells following stimulation with anti-NK1.1 mAb (PK136). Representative flow cytometric plots are shown, with numbers in the quadrants indicating the percentage of cells in each region. Data are presented as mean ± SD. Statistical comparisons between CD127 + and CD127 − subsets were performed using an unpaired two-tailed Student’s t -test. * p < 0.05, ** p < 0.01. IFN-γ—interferon-γ; mAb—monoclonal antibody.
Article Snippet: Briefly, NK cell-mediated cytotoxicity was assessed by measuring 51 Cr-release following the incubation of freshly isolated, unstimulated effector cells with 51 Cr-labeled YAC-1 target cells (ATCC).
