Unique liver transcriptomics profiles in chronic HBV: intrinsic intrahepatic functional clusters discriminate distinct clinical phases

Project description:Since little information is available on the processes in the liver associated with the natural history during chronic HBV infections, we now examined hepatic transcriptomes to identify distinctive gene expression profiles in the HBV clinical phases. We show that the transcriptomes of mild fibrotic, HBV-infected livers were significantly different from those with comorbidities. Across the clinical HBV phases, comparable intrahepatic ISG expression was observed. However, global transcription was most distinctive between the immunotolerant and the immunoactive phases (n=92 genes), followed by the immunotolerant and the HBeAg-negative hepatitis phase (n=71 genes), and the immunotolerant and the inactive carrier phase (n=46 genes). Among these were CD19, TNFRSF13C, granzyme H, and KIR2DS3. Moreover, during these clinical phases, 4 intrinsic functional clusters (IFC) with distinctive transcriptional activity were identified by combined global module analysis. These discriminative clusters contained B-cell and cell cycle-related genes, which were highly expressed in liver during the immunoactive phase; and NK-cell and mitochondria respiration-related genes in the HBeAg-negative hepatitis phase. Our data define distinctive transcriptomes in the liver during HBV clinical phases. We observed important differences between the liver and blood in transcription levels of ISG and cell cycle genes, but, strikingly, also a high degree of overlap in expression patterns of B- and NK-cell genes during the immune active phases.

Project description:In this study gene expression of human blood classical monocytes (CD14++CD16-), CD16 positive monocytes (consisting of non-classical CD14+16++ and intermediate CD14++CD16+ monocytes) and CD1c+ CD19- dendritic cells from healthy subjects were investigated.

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.

SuperSAGE evidence for CD14++CD16+ monocytes as a third monocyte subset

Project description:Monocytes are a heterogeneous cell population with subset-specific functions and phenotypes. The differential expression of CD14 and CD16 distinguishes classical CD14++CD16-, intermediate CD14++CD16+ and non-classical CD14+CD16++ monocytes. However, CD14++CD16+ monocytes remain the most poorly characterized subset so far. Therefore we analyzed the transcriptomes of the three monocyte subsets using SuperSAGE in combination with high-throughput sequencing. Analysis of 5,487,603 tags revealed unique identifiers of CD14++CD16+ monocytes, delineating these cells from the two other monocyte subsets. CD14++CD16+ monocytes were linked to antigen processing and presentation (e.g. CD74, HLA-DR, IFI30, CTSB), to inflammation and monocyte activation (e.g. TGFB1, AIF1, PTPN6), and to angiogenesis (e.g. TIE2, CD105). Therefore we provide genetic evidence for a distinct role of CD14++CD16+ monocytes in human immunity. Human monocyte subsets (CD14++CD16-, CD14++CD16+, CD14+CD16++) were isolated from 12 healthy volunteers based on MACS technology. Total RNA from monocyte subsets was isolated and same aliquots from each donor and monocyte subset were matched for SuperSAGE. Three SuperSAGE libraries (CD14++CD16-, CD14++CD16+ and CD14+CD16++) were generated.

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.
