Arrows indicate individual YFP+ cells.(F) Quantification of NKp46-YFP+ cells per square millimeter in images of different regions of the nerve. Two-way ANOVA: effect of IL-2 complex, F(1,16) = 56.31, p < 0.0001; effect of region, F(3,16) = 23.73, p < 0.0001.

NKp46+DX5+ NK cells (t = 15.37, ∗∗∗p < 0.0001), CD3+CD8+ T cells (U = 22.00, p = 0.1473), and CD3+CD4+ T cells (t = 3.035, p = 0.0079). Student’s unpaired t test was used.(I) Loss of NKp46-YFP+ cells from peripheral blood in anti-NK1.1-antibody-treated mice. Student’s unpaired t test, t = 15.51, ∗∗∗p = 0.0001.(J) Wild-type mice received either anti-NK1.1 to deplete NK cells or isotype control antibody followed by partial crush of the sciatic nerve on day 0. All mice were treated with IL-2 antibody complex (arrows). Two-way ANOVA. Effect of antibody depletion: F(1,240) = 21.21, p < 0.0001. Bonferroni post-test, ∗∗∗p < 0.001 (t = 4.542).(K) Heatmap showing mean sensitivity to pinprick along the lateral hind paw. Note the broad loss of sensitivity at day 6 in isotype control mice.(L) Area under the curve measurements in isotype control and anti-NK1.1-treated mice following IL-2 complex treatment. days 1–4: t = 0.1508, p = 0.8815; days 5–10: t = 2.390, p = 0.0295; days 11–15: t = 1.040, p = 0.3130).

Acutely Cultured Embryonic but Not Adult DRG Neurons Reveal Susceptibility to NK-Mediated Cytotoxicity by RAE1(A) Immunolabeling of co-culture (4 h) between embryonic (top) or adult (bottom) DRG neurons ( beta-tubulin, magenta) and either freshly isolated (control) or IL-2-stimulated natural killer (NK) cells (NKp46, green).
