Peripheral blood mononuclear cells single-cell landscape of newly diagnosed NK/T cell lymphoma patients

ABSTRACT: Natural killer/T cell lymphoma (NKTCL) is a rare and aggressive form of non-Hodgkin's lymphoma associated with Epstein-Barr Virus (EBV) infection.The recent advancement of multi-omics technologies has significantly enhanced our understanding of NKTCL disease biology, including genetics, transcription landscape, variations of EBV strain, and microenvironments. Emerging evidence suggests that immunoprofiling of peripheral blood mononuclear cells (PBMCs) is associated with the treatment response of cancer patients and can be used to guide clinical trials and therapy. In this study, we utilized single-cell RNA sequencing (scRNA-seq) to comprehensively characterize the phenotypic landscape of PBMCs in newly diagnosed patients with NKTCL. This research offers a valuable peripheral blood-based signature for newly diagnosed NKTCL, which could be a crucial resource for further investigations into the pathogenesis of NKTCL and the optimization of therapeutic regimens.

Project description:Epstein-Barr virus (EBV) is an oncogenic virus that is associated with the pathogenesis of several human lymphoid malignancies, including Hodgkin's lymphoma. Infection of normal resting B cells with EBV results in activation to lymphoblasts that are phenotypically similar to those generated by physiological stimulation with CD40L plus IL-4. One important difference is that infection leads to the establishment of permanently growing lymphoblastoid cell lines, whereas CD40L/IL-4 blasts have finite proliferation life-spans. To identify early events which might later determine why EBV infected blasts go on to establish transformed cell lines, we performed global transcriptome analyses on resting B cells and on EBV and CD40L/IL-4 blasts after 7 days culture. As anticipated, there was considerable overlap in the transcriptomes of the two types of lymphoblasts when compared to the original resting B cells, reflecting common changes associated with lymphocyte activation and proliferation. Of interest to us was a subset of 225 genes that were differentially expressed between EBV and CD40/IL4- blasts. Genes which were more highly expressed in EBV blasts were substantially and significantly enriched for a set of interferon-stimulated genes which on further in silico analyses were found to be repressed by IL-4 in other cell contexts and to be up-regulated in micro-dissected malignant cells from Hodgkin's lymphoma biopsies when compared to their normal germinal center cell counter parts. We hypothesized that EBV and IL-4 were targeting and discordantly regulating a common set of genes. This was supported experimentally in our model where IL-4 stimulation partially reversed transcriptional changes which follow EBV infection and it impaired the efficiency of EBV-induced B cell transformation. Taken together, these data suggest that discordant regulation of interferon and IL-4 pathway genes by EBV that occurs early following infection of B cells has relevance to the development or maintenance of an EBV-associated malignancy.
