Gene expression data from S. aureus-exposed macrophages |
| Organism |
Homo sapiens |
| Experiment type |
Expression profiling by array

| Summary |
It is becoming increasingly apparent that Staphylococcus aureus are able to survive engulfment by macrophages, and that the intracellular environment of these cells, which is essential to innate host defenses against invading microorganisms, may in fact provide a refuge for staphylococcal survival and dissemination. Based on this, we postulated that S. aureus might induce cytoprotective mechanisms by changing gene expression profiles inside macrophages similar to obligate intracellular pathogens, such as Mycobacterium tuberculosis.
In order to examine the effect of S. aureus on the macrophage transcriptome, we performed microarray expression analysis on human monocyte-derived macrophages treated with S. aureus.

| Overall design |
Human monocyte-derived macrophages (hMDMs) were separated from fractions of peripheral blood mononuclear cells (PBMCs) obtained from the blood of healthy donors. Control and S. aureus-exposed macrophages were incubated at 37C for 8, 24, or 48 hours
