Expression data from monocyte-derived macrophages after stimulation with mock, LPS, PolyI:C and P3C.. Homo sapiens

Pre-stimulation of MDMs with LPS (signals via MyD88 and TRIF dependent pathways) and PolyI:C (signals via a TRIF dependent pathway) leads to a reduced viral infection. In contrast, pre-stimulation with P3C (signals via MyD88 dependent pathway) does not lead to a reduced viral infection. This microarray was performed to find genes that are specifically upregulated in LPS and PolyI:C stimulated MDMs but not P3C stimulated MDMs. So to give us leads into the mechanism involved in the reduction of viral infection. Overall design: MDMs of four different donors were stimulated for 4h with mock, LPS, PolyI:C or P3C. RNA was isolated and gene expression of these cells was assessed. Gene expression of LPS, PolyI:C and P3C stimulated MDMs was compared to mock.
