Figure 2.
Inhibition of gene expression in the Th1 pathway in mice infected with N67. Genes differentially expressed in N67-infected and uninfected mice with a cutoff value of 1.2-fold or larger changes were selected for analysis of gene interaction networks that were generated through the use of IPA (QIAGEN Inc., https://www.qiagenbio informatics.com/products/ingenuity-pathway-analysis). Expression and interaction network of key genes in Th1 pathways day 1 (a) and day 4 (b) post infection with N67. Red, up-regulated genes; green, down-regulated genes. Darker colors suggest higher up- or down-regulated, respectively. Symbols for molecular functions are as presented in the side box. Note: many molecules in red (up-regulated expression) day 1 post infection became green (inhibited) or gray (similar to uninfected control) day 4 post infection.
