The innate immune cytokine response is impaired in the absence of Vα14i NK T cells. D. WesleyJohnna S. TessmerMarlowe ChaukosDeanna BrossayLaurent 2013 <p><i>A</i>, Splenic leukocytes were isolated from uninfected or MCMV infected CD1d<sup>−/−</sup> and CD1d<sup>+/−</sup> littermates or Jα18<sup>−/−</sup> and Jα18<sup>+/−</sup> littermates at 1.5 days post-infection and analyzed for intracellular IFN-γ. The percentage of IFN-γ<sup>+</sup> NK cells is shown. The results are representative of 5 independent experiments (*, P<0.05). <i>B</i>, Serum levels of cytokines were measured by ELISA or using the cytometric bead array inflammation kit at 1.5 days post-infection (*, P<0.05). The results are representative of 3 independent experiments. <i>C</i>, Percent survival following high dose MCMV infection.</p>
