(Submitter supplied) MicroRNAs regulated by lipopolysaccharide (LPS) target genes that contribute to the inflammatory phenotype. Here we showed that the protein kinase Akt1, which is activated by LPS, positively regulated miRNAs let-7e, miR-181c but negatively regulated miR-155 and miR-125b. In silico analyses and transfection studies revealed that let-7e repressed Toll-like receptor 4 (TLR4) whereas miR-155 repressed SOCS1, two proteins critical for LPS-driven TLR signalling, which regulate endotoxin sensitivity and tolerance. more...

(Submitter supplied) Macrophage activation must be tightly controlled to prevent overzealous responses that cause self-damage. MicroRNAs have been shown to promote classical macrophage activation by blocking concomitant anti-inflammatory signals and transcription factors, but can also place restraints on activation by preventing excessive TLR-signalling. In contrast, the microRNA profile associated with alternatively activated macrophages and their role in regulating wound-healing or anti-helminthic responses has not yet been described. more...

(Submitter supplied) MicroRNAs (miRNAs) are short noncoding RNA molecules regulating the expression of mRNAs. Target identification of miRNAs is computationally difficult due to the relatively low homology between miRNAs and their targets. We provide data here utilizing an experimental approach to identify targets of mmu-miR-378-3p, where mmu-miR-378-3p was overexpressed and silenced in NIH-3T3 murine fibroblasts and compared to control RNA transfected cells (RISC-free siRNA). more...

(Submitter supplied) To examine the early (4h) miRNAs responses of differentiated macrophages to LPS challenge, we performed global miRNA profiling using the Nanostring nCounter technology, a multiplexed, color-coded probe assay. Of the 653 probes present on the assay, we detected expression of ~200 (30%) miRNAs across all samples.

(Submitter supplied) Aberrantly expressed miRNAs contribute to developmental abnormalities and diseases such as cancer, diabetes, and cardiovascular disorders, by hybridizing to specific mRNA targets and repressing their translation into proteins. Although miRNA expression signature is characterized in the process of neointimal thickening during proliferative vascular diseases such as atherosclerosis, so far global miRNA expression profiling in the different stages of atherosclerosis is completely unknown. more...

(Submitter supplied) Investigation of whole genome gene expression level changes in a Tim-3 knockdown RAW264.7 cell, compared to control siRNA transfected RAW264.7 cell. The Tim-3 knockdown of this cell render it hyper-reactive to TLR stimulation. Tim-3 knockdown analyzed in this study are further described in Li Y, Feng J, Geng S, Geng S, Wei H, Chen G, Li X, Wang L, Wang R, Peng H, Han G, Shen B, Li Y. 2011. The N- and C-terminal carbohydrate recognition domains of galectin-9 contribute differently to its multiple functions in innate immunity and adaptive immunity. more...

(Submitter supplied) Alcohol abuse can induce brain injury and neurodegeneration, and recent evidence shows the participation of immune receptors toll-like in the neuroinflammation and brain damage. We evaluated the role of miRNAs as potential modulators of the neuroinflammation associated with alcohol abuse and the influence of the TLR4 response. Using mice cerebral cortex and next-generation sequencing (NGS), we identified miRNAs that were differentially expressed in the chronic alcohol-treated versus untreated WT or TLR4-KO mice. more...

C57BL/6 mice which received intraperitoneal injections of different concentration (ranged from 10 to 1000 μg) of LPS originated from different bacteria, including E. coli, Klebsiella pneumonia, Pseudomonas aeruginosa, Salmonella enterica, and Serratia marcescens were sacrificed at indicated survival times (2, 6, 24, and 72 h) following LPS injection. more...

(Submitter supplied) MicroRNAs have well-established roles in eukaryotic host responses to viruses and extracellular bacterial pathogens. In contrast, microRNA responses to invasive bacteria have remained unknown. Here, we report cell type-dependent microRNA regulations upon infection of mammalian cells with the enteroinvasive pathogen, Salmonella Typhimurium. Murine macrophages strongly up-regulate NF-κB associated microRNAs; strikingly, these regulations which are induced by the bacterial lipopolysaccharides (LPS) occur and persist regardless of successful host invasion and/or replication, or whether an inflammatory response is mounted, suggesting that microRNAs belong to the first line of anti-bacterial defence. more...

(Submitter supplied) Endotoxin/LPS tolerance is a tightly regulated phenomenon, which, during infection, prevents systemic hyper-inflammation. Here we report for the first time that morphine reversal of endotoxin tolerance resulting in persistent inflammation thus contributing to septicemia and septic shock. We further report that this regulation is mediated by LPS-induced down-regulation of microRNAs 146a and 155. However, only over-expression of miR-146a, but not miR-155 abrogates morphine mediated hyper-inflammation, while antagonizing miR-146a (but not miR-155) augments morphine mediated hyper-inflammation. more...
