From: Host lung gene expression patterns predict infectious etiology in a mouse model of pneumonia
Differential gene expression 18 hours after infectious challenge. (A) A heatmap shows the expression patterns of 367 DEGs after inhalational challenge with P. aeruginosa, S. pneumoniae, A. fumigatus or PBS (sham). By unsupervised clustering, the samples all correctly segregate themselves by condition. (B) A Venn diagram indicates the striking specificity of these expression patterns, with <10% of DEGs induced or repressed by more than one condition.
