Project description:Gene expression analysis of CD11c+ splenic DCs day 7 after allo-HSCT.
| PRJNA261455 | ENA
Project description:This SuperSeries is composed of the following subset Series: GSE22127: Expression profiling of small intestine lamina propria dendritic cells GSE22128: Expression profiling of splenic dendritic cells Dendritic cells play a vital role in initiating robust immunity against pathogens as well as maintaining immunological tolerance to self antigens, food antigens and intestinal commensals. However, the intracellular signaling networks that program DCs to become tolerogenic are largely unknown. To address this, we analyzed gene expression profiles using microarray analysis of purified intestinal lamina propria DCs (CD11c+ CD11b+ DCs and CD11c+ CD11b- DCs) and compared it to splenic DCs (CD11c+ DC), from mice. We sought to determine the unique genetic profile of small intestine lamina propria CD11c+ cells compared to splenic CD11c+ cells. We performed a meta-analysis using the expression profiles of Intestinal lamina propria CD11c+ CD11b+ DCs (GSM550122), Intestinal lamina propria CD11c+ CD11b- DCs (GSM550121) and Splenic CD11c+ DCs (GSM550126). This study combined and re-normalized the microarray data from GSE22127 and GSE22128 studies. Refer to individual Series for additional details

Project description:Analysis of gene expressions in mouse splenic dendritic cells (DCs). DCs were purified into two subsets, CD8-positive and -negative ones. DCs were expanded in vivo by injecting Flt3L-producing tumors into the backs of C57BL/6 mice. To expand DCs in vivo, Flt3L-producing B16 melanoma cells were injected to the backs of mice. Then, 10-12 days later, splenic DCs were enriched by MACS and purified into CD3-B220-CD8a+CD11c+ and CD3-B220-CD8a-CD11c+ cells by FACS cell sorter.

Project description:Dendritic cells (DCs) play a vital role in innate immunity. Transcriptome of DCs isolated from mouse spleen was obtained and deposited here. Keywords: Spleen, DCs We sought to determine the expression profile of splenic CD11c+ cells. RNA was extracted from DCs sorted from mouse spleen (CD11c+ cells) and hybridized on Affymetrix microarrays.

Project description:Transcriptome analysis of thymic APC subsets, mTECs and thymic DCs in comparison to splenic DCs
| PRJNA281042 | ENA
Project description:Mouse splenic dendritic cells are divided into different subsets based on their phynotype. CD8α+ and CD8α- dendritic cells play different roles against pathogens. Cross-presentation is essential for immune defense against viruses, tumors and intracellular bacteria and CD8α+ DCs are more potent in cross-presentation compared to CD8α- DCs. We used microarrays to detail the global gene expression to analyze the underlying mechanism in CD8α+ dendritic cells cross-presentation Splenic CD8α+ and CD8α- dendritic cells were sorted by flow-cytometer for RNA extraction and hybridization on Affymetrix microarrays. Thirty C57BL/6J mice were sacrified for the splenic cells, splenic DCs were enriched by negtive selection, then CD8α+ and CD8α- dendritic cells were seprated based on CD11c and CD8α markers.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.
