Cytokine profiles in challenged chambers.

<p>TNF-α levels were determined by ELISA in chamber exudates of Ncr1<i>^+/+</i> (WT) and Ncr1<i>^gfp/gfp</i> (KO) mice at baseline (0), 2 h and 24 h following bacterial challenge. Data represent absorbance at 650 nm ± SD and are average of three different experiments. ** <i>p</i><0.01.
