Expression data from primary human healthy donor-derived CD14- cDC2s, CD14+ cDC2s and monocytes

Project description:The human dendritic cell (DC) family has recently been expanded by CD1c+CD14+CD163+ DCs, introduced as DC3. DC3 are found in tumors and peripheral blood of cancer patients but which cells can serve as their pre-cursors remain unknown. CD1c+CD14+ cells share similarities with both CD1c+ DCs (cDC2s) and CD14+ monocytes on transcriptomic and phenotypic level. To investigate whether CD14+ cDC2s are closer related to CD14- cDC2s or monocytes on transcriptomic level, we analyzed their RNA.

Comparative gene expression analyses of purified CD14+ monocytes from human umbilical cord blood, CD14+ monocytes from adult peripheral blood and the cell therapy product DUOC-01

Project description:DUOC-01 is a macrophage-like cell therapy product manufactured from human umbilical cord blood (CB) mononuclear cells (MNCs) and intended for use in treatment of demyelinating diseases. During the 21-day manufacturing process, most initiating MNCs die in culture, but a highly active, adherent population of cells that resemble hematopoietic lineage macrophage in morphology, phagocytic activity, and antigen expression emerges; this population comprises the final DUOC-01 product [Kurtzberg et al. 2015]. Using the cuprizone-mediated murine demyelination model, we have found that DUOC-01 cells are capable of accelerating the remyelination process. In the same demyelination model, human cord blood-derived CD14+ cells (CBCD14) were less active. In another cellular therapy project, we have found that CBCD14 protects brain cells from oxygen-glucose-deprivation (OGD), but adult peripheral blood-derived CD14+ monocytes (PBCD14) did not. To address the functional differences between these cell types, we have analyzed differential gene expression by these three cell types. We used four cord blood (CB) samples (from Carolinas Cord Blood Bank) that were collected within 24hrs of delivery. Then, highly purified CB CD14+ monocytes were isolated by flow sorting. We collected the peripheral blood (PB) from four healthy volunteers and isolated the purified PB CD14+ monocytes by cell sorting. Three separate batches of cultured DUOC-01 cells were collected from Robertson Cell and Translational Cell Therapy cGMP facility. Total RNAs were isolated at the same time and kept frozen. RNA samples were given to Duke Microarray core facility to analyse the gene expression profile using Affymetrix GeneChipÂ® Human Genome U133 Plus 2.0 Assay.

Transcription profiling by array of human serum-free fibrocytes, serum-containing fibrocytes, CD14++CD16- Monocytes, CD14++CD16+ Monocytes, CD14+CD16++ Monocytes and macrophages

Project description:Serum-free Fibrocytes, Serum-containing Fibrocytes, CD14++CD16- Monocytes, CD14++CD16+ Monocytes, CD14+CD16++ Monocytes, Macrophages were all generated from up to 3 biological replicates from each of 3 separate donors. RNA was extracted (Ambion RNAqueous), labelled with cy3, mixed with cy5 labelled human reference (Stratagene), and hybridised to slides printed with Human AROS v4.0 oligonucleotides (Operon). Slides were scanned using a Perkin Elmer GX plus, and the data then normalised with GEPAS v4.0 and collated. Final data analysis was carried out using TMEV 4.0. SAM was performed using a 0.1% FDR. PCA were plotted from this list, and interrogation carried out using DAVID to determine pathway enrichment.

Transcriptome analysis of CD14+ monocytes from SSc patients

Project description:Purpose: To compare transcriptome profile of CD14+ blood monocytes from systemic sclerosis (SSc) patients and healthy controls. Methods: CD14+ monocytes were isolated from peripheral blood of lcSSc (n=5, age=54.4±6.7), dcSSc patients (n=5, age=51.8±7.2) and age- and sex-matched healthy controls (HC) (n=5, age=50.8±9.7). Total RNA was isolated and polyA libraries were prepared using TruSeq Stranded mRNA kit. Next Generation Sequencing was performed using Illumina HiSeq 4000 platform. Differentially expressed genes were computed using DESeq2 algorithm. Results: We detected 1440 differentially expressed genes between dcSSc vs HC and 225 between lcSSc and HC respectively (p≤0.01; log2 ratio≥0.5, Fig 1). Among those, in dcSSc 1076 were upregulated (e.g. MMP9, IL1R2, FLT3, MIF, TLR9) and 364 were downregulated (e.g. TGFBR1, CD44, CD244, HLA-DRA, HLA-G). In lcSSc 160 transcripts were upregulated (e.g. CCL2, WNT5B, MMP17) and 65 were downregulated (e.g. KLF11, IRAK2). We identified 123 commonly deregulated genes between SSc subgroups (e.g. CCL3, CD14, IL27, MMP17). Principal component analysis showed close clustering within SSc subgroups and clear separation from healthy controls. Pathway analysis revealed alterations in several biological processes important in fibrogenesis including antigen presentation, MIF-induced immune responses, TGF-β, NOTCH and WNT signalling pathways. qPCR analysis further confirmed differences in gene expression on mRNA level (n HC=8, n SSc=25, p≤0.05). Conclusions: To our knowledge, this is the first global transcriptome analysis of peripheral blood CD14+ monocytes in SSc. Our results suggest a primary activation of monocytes in peripheral blood, which might be further translated into novel cellular biomarker of the disease and potentially used for distinguishing between responders and non-responders to a novel treatment in future clinical trials.
