Project description:Skin and blood single cell RNA sequencing datasets of IL-22- and IFNγ-secreting CD1a-reactive GAS-responsive T cells were generated from four healthy skins, five healthy PBMCs and three psoriatic PBMCs. Using cellular indexing of transcriptomes and epitopes by sequencing (CITE-seq), we measured T cell specific functional states at both protein and transcriptome levels.

Project description:Purpose: The present study is aiming to understand transcriptome changes during psoriatic changes using high-throughput sequencing and thereby comprehensively assess the diseases and guide future research directions. Methods: Clinical psoriatic samples, including psoriatic lesions and their adjacent normal skin samples, and the surgical derived skins from healthy individuals as comparative controls were collected and analysed of their RNA expression profile using Illumina HiSeq 4000. raw sequencing reads were processed and pre-qualified using Trimmomatic and Fragments Per kb Per Million Reads (FPKM) method was used to calculate the abundance of each transcript followed by Negative Binomial Distribution tests to identify significant differences in each comparison. Results: Total reads for mRNAs, lncRNAs and miRNAs was 108,552, 105,136 and 2762, respectively, including 649 novel lncRNAs and 905 novel miRNAs. 5383 DE_mRNAs, 1201 DE_lncRNAs and 80 DE_miRNAs were identified in the comparison of the psoriasis lesions-adjacent normal group (PN) vs. healthy control-derived normal skin group (NN; PN vs. NN). A total of 9513 DE_mRNAs, 1940 DE_lncRNAs and 251 DE_miRNAs were identified in the psoriasis lesion group (PS) vs. NN comparison (PS vs. NN), and 4946 DE_mRNAs, 1559 DE_lncRNAs and 92 DE_miRNAs were identified in the PS vs. PN comparison. Conclusions: We identified numerous differentially expressed RNAs, including mRNAs, long non-coding RNAs (lncRNAs) and microRNAs (miRNAs). Our results reveal transcriptomic changes, expand our mechanistic understanding of psoriasis, and may lead to new directions for psoriasis research.

Project description:We report the application of Illumina small RNA sequencing to normal human skin, as well as uninvolved and involved psoriatic skin. By obtaining over 600 million qualified reads from 20 healthy controls and 47 psoriasis biopsies (uninvolved/involved), we have generated a complete small RNA profile in normal and diseased human skin, with particular emphasis on miRNAs. We report the discovery of 284 putative novel miRNAs as well as 98 differentially expressed miRNAs in psoriatic skin.

Project description:To shed lights on the potential candidate genes and molecular pathways in vitiligo pathomechanism and therapeutics, we compared the transcriptomes between depigmented and normal skin in Ets-1 knockout mice that spontaneously exhibit human vitiligo-like depigmentation. We performed gene expression profiling analysis using data obtained from RNA-seq of 1 depigmented and 1 pigmented skins of Ets-1 KO mice, and 1 normal skins of wild-type mice.

Project description:Object: To study the difference of gene expression pattern of bone marrow mesenchymal stem cells (BMMSCs) between psoriatic patients, normal adults and aborted fetuses, and then to explore the influence of bone marrow mesenchymal stem cells to immune system. Methods: Bone marrow mononuclear cells (BMMNC) of 7 psoriatic patients, 4 healthy volunteers and 3 aborted fetuses were isolated and the BMMSCs were cultured using the adherent method. Gene expression of 14 samples was detected by gene microarray and the different expressed genes were analysised by SAM software. Results: 654 differentially expressed genes (66 up regulated, 588 down regulated) were detected between the psoriatic patients and normal adults, which were enriched in immune response, chemotaxis and cell adhesion etc. 2020 differentially expressed genes (888 up regulated, 1132 down regulated) were detected between the aborted fetuses and normal adults. These genes were enriched in cell cycle, cell division, immune response and MHC class II antigen etc. Conclusion: The gene expression pattern such as immune response, chemotaxis was aberrant in psoriatic BMMNCs, which was consistent with aborted fetuses in some immune related genes. Bone marrow mononuclear cells (BMMNC) of 7 psoriatic patients, 4 healthy volunteers and 3 aborted fetuses were isolated and the BMMSCs were cultured using the adherent method. Gene expression of 14 samples was detected by gene microarray and the different expressed genes were analyzed by SAM software.
