Proteomic profiling of human decidual immune proteins during Toxoplasma gondii infection

Project description:A Toxoplasma gondii infection during pregnancy can result in spontaneous abortion, preterm labor, or congenital fetal defects. The decidual immune system plays a critical role in regulating the immune micro-environment and in the induction of immune tolerance. To better understand the factors that mediate the decidual immune response associated with the T. gondii infection, a large-scale study employing TMT proteomics was conducted to characterize the differential decidual immune proteomes from infected and uninfected human decidual immune cells samples. The decidual immune cells from 105 human voluntary abortion tissues were purified, and of the 5510 unique proteins identified, 181 proteins were found to be differentially abundant (>1.2-fold cutoff, P＜0.05) in the T. gondii-infected decidual immune cells. 11 proteins of 181 differentially expressed proteins associated with trophoblast invasion, placental development, intrauterine fetal growth, and immune tolerance were verified using a quantitative real-time polymerase chain reaction and western blotting. This systematic research identified a broad range of immune factors in human decidual immune cells, shedding a new insight into the decidual immune molecular mechanism for abnormal pregnancy outcomes associated with T. gondii infection.

Activation of aryl hydrocarbon receptor

Project description:VAF347 is a low molecular weight compound which inhibits allergic lung inflammation in vivo. This effect is likely due to a block of dendritic cell (DC) function to generate pro-inflammatory T-helper (Th) cells since VAF347 inhibits IL-6, CD86 and HLA-DR expression by human monocyte derived DC, three relevant molecules for Th-cell generation. Here we demonstrate that VAF347 interacts with the aryl hydrocarbon receptor (AhR) protein resulting in activation of the AhR signaling pathway. Functional AhR is responsible for the biological activity of VAF347 since, i) other AhR agonists display an identical activity profile in vitro, ii) gene silencing of wild type AhR expression or forced over-expression of a trans-dominant negative AhR ablates VAF347 activity to inhibit cytokine induced IL-6 expression in a human monocytic cell line and iii) AhR deficient mice are resistant to the compound’s ability to block allergic lung inflammation in vivo. These data identify the AhR protein as key molecular target of VAF347 and its essential role for mediating the anti-inflammatory effects of the compound in vitro and in vivo.

The Aryl hydrocarbon receptor and FOS mediated cytotoxicity induced by Acenatobacter baumannii

Project description:Acinetobacter baumannii is a highly pathogenic and multidrug-resistant Gram-negative bacterium that causes severe nosocomial infections. To better understand the mechanism of pathogenesis, we compare the proteomes of uninfected and infected human cells, revealing that transcription factor FOS is the host protein most strongly induced by A. baumannii infection. Pharmacological inhibition of FOS reduces the cytotoxicity of A. baumannii in cell-based models, and similar results are also observed in a mouse infection model. A. baumannii outer membrane vesicles (OMVs) are shown to activate the aryl hydrocarbon receptor (AHR) of host cells by inducing the host enzyme tryptophan-2,3-dioxygenase (TDO), producing the ligand kynurenine, which binds AHR. Following ligand binding, AHR is a direct transcriptional activator of the FOS gene. Our results suggest that bacterial infection interacts with host tryptophan metabolism and the transcription factor FOS.

Aryl hydrocarbon receptor-interacting protein regulates tumorigenic and metastatic properties of colorectal cancer cells driving liver metastasis

Project description:Aryl hydrocarbon receptor-interacting protein (AIP), a putative positive intermediary in aryl hydrocarbon receptor-mediated signaling, is overexpressed in highly metastatic human KM12SM CRC cells, with high metastatic capacity to liver, and other highly metastatic CRC cells. Meta-analysis and immunohistochemistry were used to assess the relevance of this protein in CRC. Cellular functions and signaling mechanisms mediated by AIP were assessed by gain-of-function experiments and in vitro and in vivo experiments. A significant association of high AIP expression with poor CRC patients’ survival was observed. Gain-of-function and quantitative proteomics experiments demonstrated that AIP increased tumorigenic and metastatic properties of isogenic KM12C (poorly-metastatic) and KM12SM CRC cells. AIP overexpression dysregulated epithelial-to-mesenchymal (EMT) markers and induced several transcription factors and Cadherin-17 activation. The former induced the signaling activation of AKT, SRC, and JNK kinases to increase adhesion, migration and invasion of CRC cells. In vivo, AIP expressing KM12 cells induced tumor growth and liver metastasis. Furthermore, KM12C (poorly-metastatic) cells ectopically expressing AIP became metastatic to liver. Our data reveal new roles for AIP in regulating proteins associated with cancer and metastasis to induce tumorigenic and metastatic properties in colon cancer cells driving liver metastasis.
