  1. G-CSF granulocyte colony-stimulating factor, IL interleukin, KC keratinocyte chemoattractant, ND not detectable, TRIF Toll/interleukin 1 receptor domain-containing adaptor-inducing interferon β, WT wild type.
  2. *Significantly different between all three groups using Kruskal-Wallis test.
  3. Significantly different between WT and MyD88 using Mann–Whitney test.
  4. Parentheses: Fold change compared to baseline for that particular group.
