CD73 sorted cell RNA-sequencing and GeoMX sequencing

ABSTRACT: CD73 marks cells with increased mesenchymal morphologies and phenotypes. To understand the transcriptional differences in CD73+ and - cells, we performed bulk RNA-seq on the CD73 sorted cells. In this study, we investigated if and how transcriptional heterogeneity of EwS cells contributes to heterogeneity of tumor phenotypes in vivo. Digital spatial profiling and human whole transcriptome analysis interrogated transcriptomic heterogeneity in EwS CHLA10 cell line xenografts.

Expression data from CD73 positive adipose derived mesenchymal stem cells (CD73+ AD-MSCs) and CD73 negative adipose derived mesenchymal stem cells (CD73- AD-MSCs) of mouse

Project description:MSCs are a heterogeneous population and the specific population of MSCs may exhibit a selective ability for tissue repair. The aim of our research was to adapt the CD73+ subgroup of adipose derived MSCs (AD-MSCs) for the therapy of myocardial infarction (MI). Our results revealed that CD73+ AD-MSCs played more effective role in the acceleration function of cardiac recovery by promoting angiogenesis in a rat model of MI compared to mixed AD-MSCs and CD73- AD-MSCs. Microarray analysis shows differences between CD73+ and CD73- AD-MSCs when transcription profile of these two subgroups were compared, especially in VEGF pathway.

CD73+ memory CD4 T cells are a long-lived population with elevated effector function and prone to differentiate into TRM-like cells [ATAC-seq]

Project description:The understanding of heterogeneity of human memory T cells will help to know the function, development and maintenance of memory population, then to improve the recall response or effective immunotherapy. Ecto-5’-nucleotidase CD73 expression in four subsets of memory T cells decreases with aging. The resistance to apoptosis and high expression of IL7R entitle CD73+ memory T cells to be long-lived population. We found antigen-specific memory T cells have overwhelming CD73 expression. The transcriptional and chromatin accessibility profiles indicate the elevated effector functions in CD73+ memory CD4 T cells comparing to CD73- counterparts. Homer analysis and Transcriptional factor (TF)-regulatory element-target gene triplet network clearly show the crucial role of RUNT and NR family TFs in CD73+ cells. Furthermore, CD73+ memory CD4 T cells were prone to differentiate into TRM-like cells under in-vitro sequential TCR and TGF/IL-15 signaling. The decreased percentage of CD73+ memory T cells with age leads to the less replenishment of TRM cells from peripheral blood.

CD73 knockdown effect in pancreatic cancer cell lines

Project description:Recent studies have shown that non-enzymatic function of CD73 play a key role in tumor progression, but this function of CD73 in pancreatic cancer cells has not been studied. In the present study, PANC-1 cell lines were transfected with CD73 siRNA, and proliferation ability and cell cycle was significantly inhibited. However, little is known about the mechanisms involved in CD73 regulation in tumors.

CD73 Immune Checkpoint Defines Inducible Regulatory NK cells in the Tumor Microenvironment

Project description:High levels of ecto-5'-nucleotidase (CD73) have been implicated in immune suppression and tumor progression. Elevated levels of CD73 has also been observed in patients who progress on anti–PD-1 immunotherapy. While regulatory T cells can express CD73 and inhibit T cell responses via the production of adenosine, less is known if conventional T cells and natural killer (NK) cells can express CD73. We found that the expression of CD73 is restricted to tumor-infiltrating NK cells and the frequency of these cells correlate with larger tumor size in patients with breast cancer. In addition, the expression of other immune checkpoint receptors including LAG-3 and VISTA was significantly higher in CD73 positive NK cells than on CD73 negative NK cells. Furthermore, the prognostic value of CD73 gene expression was influenced by NK cell signature expressed in patients with breast cancer and sarcoma. Mechanistically, upon engagement of 4-1BBL on tumor cells, NK cells transport CD73 in intracellular vesicles to the cell surface and extracellular space via actin polymerization-dependent exocytosis. These CD73 positive NK cells undergo transcriptional reprogramming and upregulate IL10 production via STAT3 transcriptional activity and suppress CD4 T cell activity. Altogether, our results support that tumors can hijack NK cells as a means to escape immunity and that CD73 expression defines an inducible population of NK cells with immune regulatory properties within the tumor microenvironment.

The Hypoxia-regulated Ectonucleotidase CD73 is a Host Determinant of HIV Latency [Array]

Project description:Deciphering the mechanisms underlying viral persistence is critical to achieving a cure for HIV infection. Here, we implement a systems approach to discover molecular signatures of HIV latently-infected CD4+ T cells, identifying the immunosuppressive, adenosine-producing ectonucleotidase CD73 as a key surface marker of latent cells. Hypoxic conditioning, reflecting the lymphoid tissue microenvironment, increases the frequency of CD73+ CD4+ T cells and promotes HIV latency. Transcriptomic profiles of CD73+ CD4+ T cells favor viral quiescence, immune evasion, and cell survival. CD73+ CD4+ T cells are capable of harboring a functional HIV reservoir and reinitiating productive infection ex vivo. CD73 or adenosine receptor blockade facilitates latent HIV reactivation in vitro, mechanistically linking adenosine signaling to viral quiescence. Finally, tissue imaging of lymph nodes from HIV-infected individuals on antiretroviral therapy reveals spatial association between CD73 expression and HIV persistence in vivo. Our findings warrant development of HIV cure strategies targeting the hypoxia-CD73-adenosine axis.

Bulk RNA-seq of human adipose-derived CD73-positive cells and heterogeneous mesenchymal stem/stromal cells

Project description:To characterize the transplantation efficacy of CD73+ cells in a mouse model of colitis, we established CD73+ cells isolated from human adipose tissue and the conventional heterogeneous cell populations (from now on referred to as cMSCs) attached to the culture dish. We then performed a comparative transcriptome analysis between CD73+ cells and cMSCs derived from three individuals.
