DNA Methylation Analysis of Systemic Lupus Erythematosus

ABSTRACT: This study performed Illumina Methylation450 analysis of CD4+ T-cells, CD19+ B-cells and CD14+ Monocytes from lupus patients and controls. A validation cohort was further analyzed with the same platform using CD4+ T-cells, CD45RO-CD45RA+ naive T-cells, CD45RO+CD45RA- memory T-cells, and CD25+CD127- regulatory T-cells. SLE v Control comparisions were made within each cell type. The SLE patient samples are labeled SLEnnnn and the controls Xnnnn. The cell type CD4, CD14, CD19, Tmem, Treg, Tnaive is appended to each sample ID.

Systemic lupus erythematosus (SLE) is an autoimmune disease with known genetic, epigenetic, and environmental risk factors. To assess the role of DNA methylation in SLE, we collected CD4+ T-cells, CD19+ B-cells, and CD14+ monocytes from 49 SLE patients and 58 controls, and performed genome-wide DNA methylation analysis with Illumina Methylation 450 microarrays. We identified 166 CpGs in B-cells, 97 CpGs in monocytes, and 1,033 CpGs in T-cells with highly significant changes in DNA methylation le ...[more]

Expression profiles from a variety of resting and activated human immune cells

Project description:Immune cell-specific expression is one indication of the importance of a gene's role in the immune response. In order to identify such patterns, we set out to broadly profile gene expression in a variety of immune cells. We isolated twelve different types of human leukocytes from peripheral blood and bone marrow, treated them to induce activation and/or differentiation, and profiled their gene expression before and after treatment. The twelve cell types are: B cells, CD14+ cells, CD4+ CD45RO+ CD45RA- T cells, CD4+ T cells, CD8+ T cells, IgG/IgA memory B cells, IgM memory B cells, Monocytes, NK cells, Neutrophils, Plasma cells from bone marrow, and Plasma cells from PBMC.

Transcriptional analysis of naïve and central memory CD4 and CD8 T cells from healthy subjects treated with IL-27

Project description:To examine the broad impact of IL-27 on human T lymphocytes, we performed a microarray analysis assessing >20,000 well annotated genes on purified naïve (CD45RA+CD45RO-CCR7+) and central memory (CD45RA-CD45RO+CCR7+) CD4+ and CD8+ T cells from three healthy donors that were activated in vitro (plate bound anti-CD3 and soluble anti-CD28) in the presence or absence of human recombinant IL-27 (100 ng/mL). Our goal was to investigate the impact of interleukin-27 on the gene expression profil of human CD4 and CD8 T lymphocytes.

Functional and transcriptional heterogeneity of human hemopoietic lympho-myeloid progenitors

Project description:Cord blood (CB) samples from normal donors were obtained with informed consent. Fresh CB samples were processed within 18-34h after collection. Mononuclear cells were isolated and CD34+ fraction was separated. CB CD34+ enriched fraction was lineage depleted by staining with purified anti-human CD2, CD3, CD4, CD7, CD8a, CD11b, CD14, CD19, CD20, CD56, CD235a followed by Qdot 605 conjugated goat F(ab')2 anti-mouse IgG (H+L). Cells were also stained with anti-human CD38-FITC, CD45RA-PE or -BV650, CD123-PE Cy7, CD90-biotin, CD34- PerCP and CD10-APC. Finally, cells were incubated with streptavidin-conjugated APC-eF780 and Hoechst 33258 (Invitrogen, final concentration: 1 g/ml). Populations were defined, as follows: HSC - Lin-CD34+CD38-CD90+CD45RA-CD10-, MPP - Lin-CD34+CD38-CD90-CD45RA-CD10-, LMPP - Lin-CD34+CD38-CD90-/loCD45RA+CD10-, MLP - Lin-CD34+CD38-CD90-/loCD45RA+CD10+, GMP - Lin-CD34+CD38+CD123+CD45RA+CD10-, CMP - Lin-CD34+CD38+CD123+CD45RA-CD10-, MEP - Lin-CD34+CD38+CD123-CD45RA-CD10-.

Illumina Microarray of human CD4+ T cells sorted into naive, central-memory, effector-memory, and transitioning cell populations

Project description:3 healthy donor PBMC samples were isolated from EDTA blood. Then CD4+ T cells were magnetically isolated, stained for CD3, 4, 8, 56, 62L, 197, and then naive (CD45RA+62L+CCR7+), transitioning (CD45RAmedCD45ROmed), as well as CM (CD45RO+CD62L+CCR7+) and EM (CD45RO+CD62L-CCR7-) cells were FACS-sorted. mRNA was isolated from these cells using Zymo RNA kits and subjected to an Affymetrix microarray.

Single cell RNA Sequencing (scRNA-Seq) of patient with ARPC5 deficiency and healthy control

Project description:We performed a targeted scRNA-seq approach using the BD Rhapsody™ Single Cell Analysis Systems (BD Biosciences). Peripheral blood mononuclear cells (PBMCs) were labeled with sample tags (BD Human Single Cell Multiplexing Kit) and AbSeq antibodies (CD1c, CD3, CD4, CD5, CD8, CD11c, CD14, CD16, CD18, CD19, CD20, CD21, CD23, CD24, CD25, CD27, CD28, CD31, CD38, CD40, CD44, CD45RA, CD45RO, CD56, CD62L, CD123, CD127, CD134, CD137, CD161, CD183, CD185, CD186, CD196, CD197, CD272, CD278, CD279, CD303, CD314, CD337, CD357, CD366, HLA-DR, IgD, IgM, TCRαβ, TCRγ8, Vα24-Jα18) and counted. Single-cell capture was performed using the BD Rhapsody Express following manufacturer’s instructions. The libraries were pooled and sequenced on NovaSeq 6000 S2 as a dual index pair-end run. Fastq files were processed using BD's Rhapsody analysis pipeline on the Seven Bridges Platform using default parameters, the GRCh38-PhiX-gencodev29 reference genome and the gencodev29-20181205 transcriptome annotation. Data (molecules per gene per cell based on DBEC error correction) were analyzed using BD SeqGeq v1.8 and the Seurat plug-in to perform dimensionality reduction (UMAP) and differential analysis output for selected cell subsets (CD4+ T cells, CD8+ T cells, NK cells, NKT cells, classical monocytes, intermediate monocytes, non-classical monocytes).

CD4+ cell transcriptional profiling by RNA sequencing

Project description:<p>We use next generation sequencing to investigate the different transcriptomes of closely related CD4+ T-cells from healthy human donors to elucidate the genetic programs that underlie their specialized immune functions. Six cell types were included: Regulatory T-cells (CD25hiCD127low/neg with >95% FOXP3+ purity), regulatory T-cells activated using PMA/ionomycin, CD25-CD45RA+ ('naive' helper T-cells), CD25-CD45RO+ ('memory' helper T-cells), activated Th17 cells (>98% IL17A+ purity) and activated IL17-CD4+ T-cells (called 'ThPI'). Poly-T capture beads were used to isolate mRNA from total RNA, and fragment sizes of ~200 were sequenced from both ends on Illumina's genome analyzer. We confirm many of the canonical signature genes of T-cell populations, but also discover new genes whose expression is limited to specific CD4 T-cell lineages, including long non-coding RNAs. Additionally, we find that genes encoded at loci linked to multiple human autoimmune diseases are enriched for preferential expression upon T-cell activation, suggesting that an aberrant response to T-cell activation is fundamental to pathogenesis.</p>
