From: Piglet innate immune response to Streptococcus suis colonization is modulated by the virulence of the strain

Figure 4

Gene expression in nasal samples after S. suis inoculation. Samples were taken at 3 days before, and 4 h, 1, 2, and 3 days after the intranasal inoculation of S. suis strains T15 (non-virulent) and S10 (virulent). A group of piglets inoculated with PBS are also shown and served as control. All the genes found to be quantifiable are shown irrespectively of their statistical significance. Gene expression was normalized relative to the 3 days before challenge mean for each inoculated group and log2 transformed. Values are presented as a heat map. Numbers in abscissa axis represent animal ID. Color scale was limited to ± 5 and out of bounds values displayed with the maximum intensity color. Gene functional groups: Apop.: Apoptosis; Chemo.: Chemokines; M.: Miscellaneous; P.R.R.: Pattern Recognition Receptors. IL1B_1 and IL1B_2 are both IL1B assays consisting of two different primer pairs targeting non-overlapping sites in the IL1B transcript. Samples marked with a black cross: expression level not quantifiable.
