Project description:Microarray analysis of IECs from Tlr5+/+ and Tlr5â/â mice stimulated with either medium alone or flagellin (1 µg/ml); to elucidate TLR5-mediated immune responses in CD11c+ LPCs Experiment Overall Design: CD11c+ LPCs from Tlr5+/+ and Tlr5â/â mice were treated with or without flagellin (1 ïg/ml) for 4 h. Total RNA was extracted with an RNeasy kit (Qiagen), and purified using an Oligotex mRNA Kit (Pharmacia). Fragmented and biotin-labeled cDNA was synthesized from 100 ng purified mRNA using the Ovation Biotin System (Nugen), according to the manufacturerâs protocol. cDNA was hybridized to Affymetrix Murine Genome 430 2.0 microarray chips (Affymetrix) according to the manufacturerâs instructions. Hybridized chips were stained, washed and scanned using a GeneArray Scanner (Affymetrix). Data analysis was performed with Microarray Suite software (Version 5.0, Affymetrix) and GeneSpring software (Silicon Genetics).

Project description:Innate immune memory is a new concept describing ability of innate myeloid and lymphoid cells to gain memory characteristics after transient stimulation, resulting in an nonspecific modified response upon secondary challenge. In recent work, we demonstrated that bronchial epithelial cells, non immune cells, that are the first immune cells of the lower respiratory tract to encounter pathogens were capable of innate immune memory after pre-exposure to Pseudomonas aeruginosa flagellin. In the present study we identified chromatin modifications induced by flagellin pre-exposure that sustain reprogramming of transcriptional patterns. We researched chromatin structure modifications responsible for the modulation of gene expression and thus of innate memory induced by the exposure of cells to flagellin.
