Single-Cell Transcriptomics Reveals Peripheral Immune Responses in Non-Segmental Vitiligo

Project description:Vitiligo is a common autoimmune depigmented dermatology due to the destruction of melanocytes. Much evidence suggests that vitiligo is associated with systemic immune activation. Previous studies have focused on immune cell infiltration in and around lesion areas, while few studies have investigated the cell types and function of circulating immune cells in peripheral blood. We collected peripheral blood from five patients with progressive non-segmental vitiligo (PV) and three healthy controls (HC).Single-cell RNA sequencing(scRNA-seq) is used to investigate the mechanisms of peripheral immune responses in vitiligo patients.

Expression pattens of long non-coding RNAs in peripheral blood mononuclear cells of non-segmental vitiligo

Project description:Objective: We explored the patterns of long non-coding RNA (lncRNA) expression in peripheral blood mononuclear cells (PBMCs) from patients with non-segmental vitiligo. Methods: We used high-throughput RNA sequencing technology to generate sequence data from five patients with non-segmental vitiligo alongside five normal healthy individuals, and then performed bioinformatics analyses to detect the differential expression of lncRNA in PBMCs. Gene Ontology (GO) and pathway analyses were performed for functional annotation, and quantitative real-time polymerase chain reaction (qRT-PCR) was used to verify gene expression. Target miRNAs and mRNAs of differentially expressed lncRNAs were predicted using bioinformatics analysis. Results: A total of 292 lncRNAs were differentially expressed in non-segmental vitiligo (fold change≥2.0, P<0.05), of which 171 were upregulated and 121 were downregulated. Six differentially expressed lncRNAs were selected , namely ENST00000460164.1, ENST00000393264.2, NR-046211.1, NR-135491.1, NR-135320.1, and ENST00000381108.3, for validation by qRT-PCR. The results showed that ENST00000460164.1 and NR-046211.1 were highly expressed in PBMCs of non-segmental vitiligo. An lncRNA-miRNA-mRNA network containing two lncRNAs, 17 miRNAs, and 223 mRNAs was constructed. Conclusion: Our results revealed patterns of differentially expressed lncRNAs in the PBMCs of non-segmental vitiligo individuals. ENST00000460164.1, and NR-046211.1 may be potential biomarkers and drug targets for the treatment of non-segmental vitiligo.

The miRNAs in plasma exosomes may serve as markers for non-segmental vitiligo

Project description:More and more studies have showed that plasma exosomal miRNAs are biomarkers for disease. The aim of the study were to investigate the miRNA profiling in plasma exosomes of patients with non-segmental vitiligo (NSV) and to find biomarkers in plasma exosomes for patients with NSV. Plasma exosomes and exosomal RNA of 10 NSV patients and 10 health persons were purified by exoRNeasy Serum/Plasma Maxi Kit. The miRNA profiles of the 20 samples were sequenced using HiSeq 2500 (Illumina) and analyzed by Reads Per Million (RPM) values and edgeR algorithm. Some differently expressed miRNAs in plasma exosomes and skin tissues of the two sets were validated by qRT–PCR.Several miRNAs were confirmed by qRT–PCR and showed similar expression patterns between plasma exosomes and skin tissues. Our study depict the miRNAs expression profiles in plasma exosomes of NSV patients and suggest that several miRNAs in plasma exosomes may serve as biomarkers for NSV.

The miRNAs in plasma exosomes may serve as markers for segmental vitiligo

Project description:More and more studies have showed that plasma exosomal miRNAs are biomarkers for disease. The aim of the study were to investigate the miRNA profiling in plasma exosomes of patients with segmental vitiligo (SV) and to find biomarkers in plasma exosomes for patients with SV. Plasma exosomes and exosomal RNA of 7 SV patients and 8 health persons were purified by exoRNeasy Serum/Plasma Maxi Kit. The miRNA profiles of the 15 samples were sequenced using HiSeq 2500 (Illumina) and analyzed by Reads Per Million (RPM) values and edgeR algorithm. Some differently expressed miRNAs in plasma exosomes and skin tissues of the two sets were validated by qRT–PCR.A total of 85 miRNAs in plasma exosomes showed differential expression between SV patients and health persons, with a |log2（Fold Change）|≥1 and P-value < 0.05. Several miRNAs were confirmed by qRT–PCR and showed similar expression patterns between plasma exosomes and skin tissues. Our study depict the miRNAs expression profiles in plasma exosomes of SV patients and suggest that several miRNAs in plasma exosomes may serve as biomarkers for SV.
