Profiling the gene expression for aLTA and pLTA effect in THP1

ABSTRACT: Staphylococcus aureus lipoteichoic acid (aLTA) and Lactobacillus plantarum LTA (pLTA) engage the same Toll-like receptor 2 (TLR2) signaling pathway, but exert different effects on the innate immune/inflammatory responses. aLTA is the leading cause of gram-positive bacterial sepsis induced by S. aureus, whereas pLTA is considered as a promising therapeutic agent for pathogen-induced septic shock. The mechanisms underlying the different functions of aLTA and pLTA remain unclear. We used human oligo microarrays to investigate the transcriptomes of human THP-1 monocytes upon exposure to aLTA and pLTA. Differential gene expression profiles were observed between the aLTA- and pLTA-treated cells. The expression levels of 1301 genes in aLTA-treated cells were changed more than 2 fold. These genes
