Metabolomics analysis of human acute graft-versus-host disease reveals changes in host and microbiota-derived metabolites (Cohort 1)

ABSTRACT:

Despite improvement in clinical management, allogeneic hematopoietic stem cell transplantation (HSCT) is still hampered by high morbidity and mortality rates, mainly due to Graft versus host disease (GvHD). Recently, it has been demonstrated that the allogeneic immune response might be influenced by external factors such as tissues microenvironment or host microbiota.

Here we used high throughput metabolomics (UPLC-MS/MS) in two cohorts of genotypically HLA-identical related recipient and donor pairs. A first monocentric cohort from Saint Louis hospital (Paris, France) was used as an exploratory cohort (n=43) and a second multicentric national cohort from Cryostem biobank was used as a confimatory cohort (n=56).

Metabolomic profile markedly differed between recipients and donors. At the onset of acute GvHD, in addition to host-derived metabolites, we identified significant variation in microbiota-derived metabolites, especially in Aryl hydrocarbon Receptor (AhR) ligands, bile acids and plasmalogens. Altogether, our findings support that the allogeneic immune response during acute GvHD might be influenced by bile acids and by the decreased production of AhR ligands by microbiota that could limit indoleamine 2,3-dioxygenase (IDO) induction and influence allogeneic T-cell reactivity.

Project description:Neural control of visceral organ function is essential for homeostasis and health. Intestinal peristalsis is critical for digestive physiology and host defence and is often dysregulated in gastrointestinal (GI) disorders. Luminal factors, such as diet and microbiota regulate neurogenic programs of gut motility, but the underlying molecular mechanisms remain unclear. Here we show that the transcription factor Aryl hydrocarbon Receptor (AhR) functions as a biosensor in intestinal neural circuits linking their functional output to the microbial environment of the gut lumen. Using nuclear RNA sequencing of mouse enteric neurons representing distinct intestinal segments and microbiota states, we demonstrate that the intrinsic neural networks of the colon exhibit unique transcriptional profiles controlled by the combined effects of host genetic programmes and microbial colonisation. Microbiota-induced expression of AhR in neurons of the distal gastrointestinal tract enables them to respond to the luminal environment and induce expression of neuron-specific effector mechanisms. Neuron-specific deletion of Ahr or constitutive overexpression of its negative feedback regulator CYP1A1, results in reduced peristaltic activity of the colon, similar to that observed in microbiota-depleted mice. Finally, expression of Ahr in enteric neurons of antibiotic-treated mice partially restores intestinal motility. Taken together, our experiments identify AhR signalling in enteric neurons as a regulatory node that integrates the luminal environment with the physiological output of intestinal neural circuits towards gut homeostasis and health. The enteric nervous system (ENS) encompasses the intrinsic neural networks of the gastrointestinal (GI) tract, which regulate most aspects of intestinal physiology, including peristalsis. In addition to host-specific genetic programmes, microbiota and diet have emerged as critical regulators of gut tissue physiology and changes in the microbial composition of the lumen often accompany GI disorders. We found that gut environmental sensor Aryl hydrocarbon receptor (AhR) is induced in colonic neurons in response to microbiota colonisation and regulates intestinal peristalsis in an AhR ligand-dependent manner. In this experiment, we used RNA sequencing to identify genes regulated in mouse colonic neurons by AhR activation.

Project description:Background: The Aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor that is activated by xenobiotic chemicals that function as AHR ligands. The response to xenobiotic AHR ligands is toxicity and the induction of drug metabolizing enzymes. The impact of AHR knockdown on gene expression and pathways in human breast cancer cells in absence of xenobiotic AHR ligands has not been investigated on a genome-wide scale. Methods: MCF-7 cells were used as a model of human breast cancer. The AHR was silenced with short interfering RNA against AHR (siAHR). RNA-sequencing coupled with Ingenuity pathway analysis (IPA) was used to determine the impact of AHR knockdown on gene expression and pathways in the absence of xenobiotic AHR ligands. Western blot analysis and recombinant tumor necrosis factor (TNF) was used to investigate the impact of AHR knockdown on TNF induction of MNSOD expression. Results: We found that the AHR is transcriptionally active in MCF-7 breast cancer cells in the absence of xenobiotic AHR ligands. In total, the expression of 634 genes was significantly changed in AHR knockdown cells compared to controls at a false discovery rate of < 10%. The analysis confirmed that drug metabolizing enzymes were AHR targets; however, we found that AHR also promoted the expression of genes that were not directly related to the metabolism of xenobiotics, such as those involved in lipid and eicosanoid synthesis. Gene pathway analysis of the AHR regulated gene dataset predicted TNF activity to be reduced in AHR knockdown cells. Our finding that AHR knockdown inhibited TNF-stimulated increases in MNSOD expression confirmed this IPA prediction. Conclusions: This is the first gene expression profiling study of AHR knockdown breast cancer cells. Several known and novel AHR targets were identified. The results suggest that endogenous AHR regulation impacts eicosanoid synthesis by regulating gene expression. The IPA prediction of reduced TNF activity in AHR knockdown cells was confirmed by showing that TNF-induced increases in MNSOD expression was inhibited in AHR knockdown cells. The requirement of AHR for MNSOD activation is novel and provides a new link by which AHR may impact reactive oxidative species (ROS) signaling. Expression profiles by mRNA sequencing were generated for human MCF-7 cells transfected with cRNAi (6 replicates) or AHR-siRNA (5 replicates) for 36hr. Sequencing was performed on an Illumina HiSeq 1000 using a 2x100 base paired-end strategy.

Project description:Understanding the mechanisms of host macrophage responses to M. tuberculosis (M.tb.) is essential for uncovering potential avenues of intervention to boost host resistance to infection. Macrophage transcriptome profiling revealed M.tb. infection strongly induced expression of several enzymes controlling tryptophan (Trp) catabolism. This included indole 2,3-dioxygenase 1 (IDO1) and tryptophan 2,3-dioxygenase (TDO2), which catalyze the rate-limiting step in the kynurenine pathway, producing ligands for the aryl hydrocarbon receptor (AHR). The AHR and heterodimeric partners AHR nuclear translocator (ARNT) and RELB are robustly expressed, and AHR and RELB levels further increased during infection. Infection enhanced AHR/ARNT and AHR/RELB DNA binding, and stimulated expression of AHR target genes, including that encoding the inflammatory cytokine IL1beta. AHR target gene expression was further enhanced by exogenous kynurenine, and exogenous Trp, kynurenine or synthetic agonist indirubin reduced mycobacterial viability. Comparative expression profiling revealed that AHR ablation diminished expression of numerous genes implicated in innate immune responses, including several cytokines. Notably, AHR depletion reduced expression of IL23A and IL12B transcripts, which encode subunits of interleukin 23 (IL23), a macrophage cytokine that stimulates production of IL22 by innate lymphoid cells. The AHR directly induced IL23A transcription in human and mouse macrophages through near-upstream enhancer regions. Taken together, these findings show that AHR signaling is strongly engaged in Mtb-infected macrophages, and has widespread effects on innate immune responses. Moreover, they reveal a cascade of AHR-driven innate immune signaling, as IL1B (IL-1β) and IL23 stimulate T cell subsets producing IL22, another direct target of AHR transactivation.

However the molecular mechanisms by which gut enviromental factors regulate ENS homeostasis remain unknown. In order to address this issue, we used RNA sequencing to identify genes specifically upregulated in mouse colonic neurons in response to microbial colonisation.
