Project description:The focus of this study was to investigate the response of cultured rainbow trout erythrocytes to lipopolysaccharide (LPS) and to the analog viral dsRNA Poly(I:C) using a salmonid-specific microarray platform enriched with immune-related genes. Although the transcriptomic response measured as the total number of differentially expressed genes was higher in LPS, the intensity response, in terms of genes with a FC>2, was greater in Poly(I:C) treated cells. These two treatments shared the regulation of some genes, but not alls followed the same pattern. Over representation of Gene Ontology functional categories showed us that Poly(I:C) treatment produced a immune response whereas LPS stimulation affect biological processes specially.

Project description:We applied Tail-end-displacement sequencing (TED-seq) for high-throughput profiling of poly(A) tail length dynamics induced by LPS stimulation in macrophage cells. We generate a time-course poly(A) tail length profiles in PMA-differentated THP-1 cells upon LPS stimulation (unstimulated, and post-stimulation 1, 2, and 4 h). This approach enabled us to profile induced poly(A) tail length dynamics with high accuracy and with 3´isoform resolution, generating a comprehensive view of poly(A) tail length dynamics induced upon an environmental signal in post-embryonic systems, and its biological implications.

Although the transcriptomic response measured as the total number of differentially expressed genes was higher in LPS, the intensity response, in terms of genes with a FC>2, was greater in Poly(I:C) treated cells. These two treatments shared the regulation of some genes, but not alls followed the same pattern. Over representation of Gene Ontology functional categories showed us that Poly(I:C) treatment produced a immune response whereas LPS stimulation affect biological processes specially. Trout erythrocytes were isolated from blood by twice Ficoll 1.007 density gradient centrifugations. For primary cell culture, erythrocytes were resuspended in DMEM (PAA Laboratories) supplemented with 10% heat-inactivated fetal bovine serum (FBS, PAA Laboratories) and the antibiotic Primocin (100 μg/ml, Invivogen) at a density of 7.5x106 cells/ml in six well cell culture plates (NUNC) and cultured at 18 ºC and 5% CO2. Erythrocytes were stimulated with LPS from E. coli (serotype 026:B6, Sigma) and Poly(I:C) (Invivogen) at 50 μg/ml, each treatment had their own control plate. All culture plates were incubated for 24h. Total RNA was extracted from the cultures using 1 ml of Tri Reagent (Sigma) following the manufacturer’s instructions with minor modifications. Quantity and integrity was analyzed by Experion RNA StdSens Analysis Kit (Bio-Rad). The design of the microarray posses 1818 genes printed in six replicates each, including random clones from common and subtracted cDNA libraries which were compared with known vertebrate proteins using blastx. The platform was enriched in immune-related genes.

Project description:Molecular Pathways and Transcriptional Networks Involved in the Macrophage Response to LPS, poly(I:C) and CpG DNA Stimulation Background: Toll-like family of receptors recognizes pathogen-associated molecular patterns (PAMPs) from different organisms. TLR4 is the receptor for bacterial lipopolysaccharide (LPS), dsRNA viral mimic poly(I:C) binds to TLR3, and bacterial CpG DNA signals through TLR9. TLR4 signaling is mediated by adaptor molecules Myd88 and TRIF while TLR3 pathway involves only the TRIF adaptor and TLR9 signals solely through Myd88. Methods: To identify genes other than those in TLR pathways that mediate macrophage response to different PAMPs, RAW264.7 cells were stimulated with LPS, poly(I:C), or CpG DNA, and RNA was profiled on microarrays 6 hrs and 24 hrs post-treatment. Gene expression data were analyzed to determine genes, pathways and transcriptional networks that are in common and unique to each of the three TLR stimuli. Potentially novel candidates revealed by this analysis were tested for their role in innate immunity using RNA interference. Results: Many genes are differentially regulated by LPS and poly(I:C) at both 6 hrs and 24 hrs following treatment, while CpG DNA elicits a much less pronounced transcriptional response. By analyzing gene expression data for networks and pathways, we prioritized differentially expressed genes that are in common to all three PAMPs as well as those shared by LPS and poly(I:C). Knockdown by RNA interference of two genes, Plec1 and TPST1, inhibited production of IL-6 in response to LPS in cultured macrophages. Conclusions: We have identified novel innate immunity genes that may be important in macrophage response to LPS, poly(I:C), and CpG DNA stimuli. Our results provide potential biomarkers and therapeutic targets that should be further investigated in mice and human populations.

Project description:The aim of the current study was to investigate the response of in vitro differentiated trout macrophages, a primary cell culture system widely used in fish immunology research, to lipopolysaccharide (LPS) and to the analog viral ds(RNA) Poly I:C. To that end we have used a salmonid-specific microarray platform enriched with immune-related genes. The results clearly suggest that the molecular mechanisms involved in the response of macrophages to LPS and Poly (I:C) are specific in some signaling pathways related to cell communication, signal transduction and kinase cascades. Nevertheless, macrophages stimulated with bacterial or viral PAMPs also activate common transcription factors.

Our results provide potential biomarkers and therapeutic targets that should be further investigated in mice and human populations. For each treatment (LPS, polyIC, CpG DNA, media only), three biological replicates (separate macrophage cultures and RNA isolations) were profiled. Each sample was labeled with Cy3 and Cy5 and co-hybridized with Stratagene Universal Mouse Reference (dye flip techical replicates). Expression at 2 timepoints (6 and 24 hours post-treatment) was assessed.

Project description:We have extended our investigation to differential immunogenicity between tolerogenic PVG rats and immunogenic LEW rats by analyzing gene expression in adipose-derived mesenchymal stem cells (ASCs) with LPS stimulation. Furthermore, to establish a direct link between gene expression and immunogenic functional annotation, ASCs from LEW and PVG rats were obtained, and the effects of inherent difference and LPS treatment on global gene expression were evaluated using microarray analyses.
