To compare the macrophage gene expression profiles induced by bacterial CpG DNA and lipopolysaccharide to better understand TLR9 and TLR4 signaling mechanisms.
Stimulated mouse macrophages with unmethylated CpG DNA or bacterial lipopolysaccharide (LPS).
Analyzed and compared differential gene expression profiles between treatments using microarray technology.
LPS altered the expression of a substantially larger number of genes in macrophages than CpG DNA.
All genes induced or repressed by CpG DNA were also induced or repressed by LPS, demonstrating that TLR9 signaling activates a subset of the TLR4 gene network.

Discussion

No takes yet. Share an insight, caveat, or question.

Implication

Experimental study reveals that CpG DNA activates a specific subset of LPS-regulated genes in mouse macrophages, suggesting distinct downstream breadth between TLR9 and TLR4 signaling.
