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.

Comparison of human CD39- and CD39+ thymus-derived regulatory T-cells

Project description:CD39- and CD39+ human thymus-derived regulatory T-cells (tTreg) present as distinct subsets with specific functional and metabolic response patterns. Both cell types express equal levels of the canonical tTreg transcription factors FOXP3 and Helios and overexpression studies have shown that CD39 expression is independent of these two transcription factors. So far, no transcriptomic analyses to adress these differences have been performed. We used microarrays to detail the global programme of gene expression between CD39- and CD39+ human tTreg and identified distinct classes of up-regulated and down-regulated genes between these two subsets.

Association of microRNAs with colon tumor metastases

Project description:We compared the expression of microRNAs in primary colon tumors with their paired liver metastases using the Nanostring human microRNA assays version 1 23 microRNAs were found to be differentially expressed between colon primary tumors and their paired metastases Total mRNA was extracted from flash frozen primary colon tumors and paired metastases. 18 tissues from 9 donors were used for this study. 100 ng of RNA was hybridized to Nanostring Human 0microRNA assays version 1.0. Data was normalized according to manufacterer's recommendation. This included background substraction and normalizing to the geometric mean of the highest 75 microRNAs.
