Single-cell profiling of the leukemic and non-leukemic immune cell compartments in CD8+ T-cell Large Granular Lymphocytic Leukemia

ABSTRACT: We performed a detailed and precise characterisation of the clonally expanded leukemic cells in CD8+ T cell Large Granular Lymphocytic Leukemia (T-LGLL). By combining scRNA+TCRÃŽÂ±ÃŽÂ²-seq with bulk RNA sequencing data we showed evidence of a strong antigen-driven immune response that shapes the entire immune cell repertoire in T-LGLL. Our study highlights how the whole immune cell repertoire including the hyperexpanded CD8+ T-LGLL cells, the non-leukemic CD8+ cells, CD4+ cells, and monocytes contribute to the CD8+ T-LGLL disease phenotype. Please note that this submission contains the fastq files while the processed count matrices can be found in ArrayExpress by the accession E-MTAB-11170.

Effector differentiation potential determined at the level of human CD8+ naïve T cell subsets [microarray]

Project description:Antigen recognition by CD8+ naïve T cells induces immune activation and rapid effector differentiation that ensures elimination of virally-infected and malignant cells. While signals from the extracellular milieu and downstream of the TCR have long been known to play a crucial role, it is currently unknown whether heterogeneity within the naïve CD8+ T cell pool shapes the potency of effector differentiation. We report the identification of two discrete subsets of human CD8+ TN cells, defined by positive and negative expression of the chemokine receptor CXCR3, with different potential to generate fully-differentiated effector T cells following antigen-specific stimulation. The CXCR3+ are more abundant than the CXCR3– naïve in peripheral blood and lymphoid tissues, retain enhanced expression of effector-related genes ex vivo and display features of the T cell receptor chain repertoire indicating enhanced capacity to bind the peptide:major histocompatibility complex. Likewise, a phenotypically equivalent murine CD8+ naïve population expressing high levels of CD5, a surrogate indicator of enhanced TCR sensitivity for self, preferentially generates short-lived effector cells following infection. Our findings imply that CD8+ T cell effector differentiation potential in humans is shaped by heterogeneity in the preimmune repertoire

Single-cell immune repertoire sequencing of B and T cells following infection and autoimmunity

Project description:Single-cell immune repertoire sequencing (gene expression and immune receptor repertoire) was performed under various contexts. This includes CD4 T follicular cells (sorted by surface expression of PD1+ CXCR5+ CD4+) following high dose LCMV clone 13 infection on days 10, 25, and 50 and low dose clone 13 infection on day 10 post infection. We additionally profiled virus-specific CD8 T cells that are specific to either GP33 or NP396. Gp33-specific CD8 T cells were sorted 15 months post infection with either low dose clone 13 LCMV, MCMV-ie2-gp33 or MCMV-m45-gp33. NP396-specific CD8 T cells were isolated either 10 days post challenge or 25 days post challenge using the viral model of dejavu (https://pubmed.ncbi.nlm.nih.gov/16604192/). B and T cells were isolated 14 days post induction of Experimental autoimmune encephalomyelitis (EAE).

The thymoproteasome hardwires the TCR repertoire of CD8+ T cells in the cortex independent of negative selection

Project description:The thymoproteasome expressed specifically in thymic cortical epithelium optimizes the generation of CD8+ T cells. However, how the thymoproteasome contributes to CD8+ T cell development is unclear. Here we show that the thymoproteasome shapes the TCR repertoire directly in cortical thymocytes before migration to the thymic medulla. We further show that the thymoproteasome optimizes CD8+ T cell production independent of the thymic medulla, independent of additional antigen-presenting cells including medullary thymic epithelial cells and dendritic cells, and independent of apoptosis-mediated negative selection. These results indicate that the thymoproteasome hardwires the TCR repertoire of CD8+ T cells with cortical positive selection independent of negative selection in the thymus.

Leukemic hematopoietic stem cell FLA2

Project description:Sca1+Lineage-cKit+ fetal liver (FL) and bone marrow (BM) cells were sorted and infected with Hoxa9+Meis retroviral particles, which provided fully leukemic complement to hematopoietic cells. These cells were injected into mice and leukemia onset was monitored in vivo. Leukemic stem cell (L-HSC) frequencies of these primary leukemias were evaluated using limiting dilution stem cell transfer in secondary recipients. The L-HSC frequency is near absolute for the FLA2 leukemia (around 1 L-HSC per 1.4 total leukemic bone marrow cells), whereas the other leukemias (FLB1, FLB2 and BM-derived leukemias) generated within the same experiment have a wide range of L-HSC frequencies.

Tunneling nanotubes contribute to the stroma-mediated imatinib resistance of leukemic cells

Project description:Intercellular communication within the bone marrow niche significantly influences leukemogenesis and the sensitivity of leukemic cells to therapy. However, the landscape of possible cell-cell interactions is still incomplete. Tunneling nanotubes (TNTs) are a novel mode of intercellular cross-talk. They are long, thin membranous conduits that enable the direct transfer of various cargo between cells. The present study found that TNTs are formed between leukemic and bone marrow stromal cells. Confocal three-dimensional reconstructions, correlative light-electron microscopy, and electron tomography provided evidence that TNTs transfer cellular vesicles between cells. The quantitative analysis demonstrated the stimulation of TNT-mediated vesicle transfer from stromal cells to leukemic cells by the stromal component. The vesicular cargo that was received from stroma cells conferred resistance to anti-leukemic treatment. Moreover, specific sets of proteins with a potential role in survival and the drug response were transferred within these vesicles. Altogether, we found that TNTs are involved in a novel and potent mechanism that participates in leukemia-stroma cross-talk and the stroma-mediated cytoprotection of leukemic cells. Our findings implicate TNT connections as a possible target for therapeutic interventions within the leukemia microenvironment to attenuate stroma-conferred protection.

Epigenomics of Human CD8 T cell Differentiation and Aging

Project description:<p>The efficacy of the adaptive immune response declines dramatically with age, but the cell-intrinsic mechanisms driving the changes characteristic of immune aging in humans remain poorly understood. One hallmark of immune aging is the loss of self-renewing naive cells and the accumulation of differentiated but dysfunctional cells within the CD8 T cell compartment. Using ATAC-seq, we first inferred the transcription factor binding activities that maintain the naive and central and effector memory CD8 T cell states in young adults. Integrating our results with RNA-seq, we determined that BATF, ETS1, Eomes, and Sp1 govern transcription networks associated with specific CD8 T cell subset properties, including activation and proliferative potential. Extending our analysis to aged humans, we found that the differences between memory and naive CD8 T cells were largely preserved across age, but that naive and central memory cells from older individuals exhibited a shift toward a more differentiated pattern of chromatin openness. Additionally, aged naive cells displayed a loss in chromatin openness at gene promoters, a phenomenon that appears to be due largely to a loss in binding by NRF1, leading to a marked drop-off in the ability of the naive cell to initiate transcription of mitochondrial genes. Our findings identify BATF- and NRF1-driven gene regulation as targets for delaying CD8 T cell aging and restoring T cell function.</p>
