Profiling of colorectal tumor-infiltrating CD8 T cells according to their expression status of CD39

Project description:Human tumors are infiltrated by various immune cells, including CD8 T cells. CD8 T cells express unique receptors that can recognize peptides at the host’s cells, including tumor cells. After probing the antigen specificity of ex-vivo tumor-infiltrating CD8 T cells from human tumors, we hypothesized that expression of CD39 was correlated with tumor-specificity. The present experiment aims at better characterizing ex-vivo CD39+ vs CD39- CD8 T cells.

Gene expression patterns of tumor-infiltrating CD8 T cells according to the CD137 expression in human metastatic ovarian cancer

Project description:We report the differences of gene expression pattern of tumor-infiltrating CD8 T cells between CD137 expressing cells and CD137 non-expressing cells in human metastatic ovarian cancer. Samples are obtained from 3 ovarian cancer patients, and we sorted CD137 expressing cells and CD137 non-expressing cells in CD39 expressing CD8 T cells for RNA sequencing. We found that even though the CD39 expression and PD-1 expression levels are similar, CD137 expressing cells showed more activated and less exhausted phenotypes than CD137 non-expressing cells.

CD39 expression identifies terminally exhausted CD8+ T cells

Project description:Exhausted T cells express multiple co-inhibitory molecules that impair their function and limit immunity to chronic viral infection. Defining novel markers of exhaustion is important both for identifying and potentially reversing T cell exhaustion. Herein, we show that the ectonucleotidse CD39 is a marker of exhausted CD8+ T cells. CD8+ T cells specific for HCV or HIV express high levels of CD39, but those specific for EBV and CMV do not. CD39 expressed by CD8+ T cells in chronic infection is enzymatically active, co-expressed with PD-1, marks cells with a transcriptional signature of T cell exhaustion and correlates with viral load in HIV and HCV. In the mouse model of chronic Lymphocytic Choriomeningitis Virus infection, virus-specific CD8+ T cells contain a population of CD39high CD8+ T cells that is absent in functional memory cells elicited by acute infection. This CD39high CD8+ T cell population is enriched for cells with the phenotypic and functional profile of terminal exhaustion. These findings provide a new marker of T cell exhaustion, and implicate the purinergic pathway in the regulation of T cell exhaustion. CD8+ T cells from subjects with HCV infection were sorted and pelleted and re-suspended in TRIzol (Invitrogen). RNA extraction was performed using the RNAdvance Tissue Isolation kit (Agencourt). Concentrations of total RNA were determined with a Nanodrop spectrophotometer or Ribogreen RNA quantification kits (Molecular Probes/Invitrogen). RNA purity was determined by Bioanalyzer 2100 traces (Agilent Technologies). Total RNA was amplified with the WT-Ovation Pico RNA Amplification system (NuGEN) according to the manufacturer's instructions. After fragmentation and biotinylation, cDNA was hybridized to HG-U133A 2.0 microarrays (Affymetrix).

PLA2G4A promotes right-sided colorectal cancer progression by inducing CD39+γδ Tregs polarization

Project description:Here, we discovered that the frequency of CD39+γδ Tregs, which positively correlated with poor prognosis, was significantly higher in right-sided colorectal cancer (RSCRC) than in the left-sided CRC (LSCRC). To explore the molecular mechanism leading to the difference of CD39+γδ Tregs derived from RSCRC and LSCRC, we collected fresh tissue samples of RSCRC with high expression of CD39+γδ Tregs and the LSCRC with low expression of CD39+γδ Tregs detected by flow cytometry and identified differential proteins by LC-MS based quantitative proteomic analysis with tandem mass tag (TMT)

Revealing and harnessing CD39 for the treatment of colorectal cancer and liver metastases by engineered T cells [NanoString]

Project description:Colorectal tumors are often densely infiltrated by immune cells that have a role in surveillance and modulation of tumor progression but are burdened by exhaustion mechanisms fueled by the tumor microenvironment, which must be counteracted to achieve control. Here, we deployed a multidimensional approach to unravel the T cell functional landscape in tumor and peritumoral tissues from primary colorectal cancers and liver metastases. We found that T-cells are mainly localized at the front edge and that tumor-infiltrating T cells co-express multiple inhibitory receptors and highlighted CD39 as the major driver of exhaustion in both primary and metastatic colorectal tumors. By CRISPR/Cas9 genome editing tools, we simultaneously redirected T-cell specificity employing a novel T-cell receptor targeting the HER-2 antigen, and disrupted CD39, thus generating triple-knockout engineered lymphocytes. We showed that the absence of CD39 confers HER2-specific T cells a functional advantage in eliminating HER2+ patient-derived organoids, starring the relevance of the CD39 axis for further exploitation in adoptive T-cell therapy strategies to treat primary and metastatic colorectal cancer.
