Gene expression analysis for CD56- T, NK, CD56+ T cells, and iNKT cells

ABSTRACT: A small subset of T cells also expresses kiler-cell immunoglobulin-like receptors (KIRs). We find that KIR+ T cells primarily reside in the CD56+ T population. However, little is known on how these cells are different from the conventional CD56- T, NK, and iNKT cells. We used microarray profiling to compare and determine the distinctive differences of CD56+ T cell and its KIR subsets when compared to the conventional CD56- T, NK and iNKT cells.

Gene expression analysis for CD56- T, NK, CD56+ T cells, and iNKT cells

Project description:A small subset of T cells also expresses kiler-cell immunoglobulin-like receptors (KIRs). We find that KIR+ T cells primarily reside in the CD56+ T population. However, little is known on how these cells are different from the conventional CD56- T, NK, and iNKT cells. We used microarray profiling to compare and determine the distinctive differences of CD56+ T cell and its KIR subsets when compared to the conventional CD56- T, NK and iNKT cells. Lymphocyte subsets were sorted from human peripheral blood mononuclear cells with FACSAriaII (BD Biosciences, San Jose, CA) using anti-CD3, anti-CD56, anti-CD14, anti-KIR2DL1, anti-KIR2DL2/3, anti-KIR3DL1 and anti-TCRValpha24 antibodies. The purity of CD3+CD56- T cells, CD3-CD56+ NK cells, CD3+CD56+ T cells, KIR-CD3+CD56+ T cells, and KIR+CD3+CD56+ T cells were more than 98% in all experiments. The purities of iNKT cells for TCRValpha24 and CD1d-tetramer were >95% and >90%, respectively. RNA pre-amplification, labeling and hybridization on Human Genome U133Plus 2.0 GeneChip array were performed in the St. Jude Hartwell Center for Bioinformatics & Biotechnology microarray core facility according to the manufacturer’s instructions (Affymetrix, Santa Clara, CA).

Gene expression profiling of NKG2C+ NK cells generated from inflammatory CD34+DNAM-1brCXCR4+ and Lin-CD34- CD16+CD56- blood precursors

Project description:There is limited knowledge on the origin and development of the ample spectrum of human NK cells, particularly of specialized NK subsets. Here, we characterized the NK cell progeny of CD34+DNAM-1bright CXCR4+ precursors that reside in healthy bone marrow and circulate in the peripheral blood (PB) of patients with chronic infections/inflammation. including HIV, HCV or HCMV reactivation after HSC transplantation. Unlike conventional CD34+ precursors they rapidly differentiated in vitro into cytotoxic, IFNγ-secreting CD94/NKG2C+KIR+CD57+ maturing NK cell progenies with HCMV-inhibiting activity. Progeny characterization led also to identification of an additional new PB Lin-CD56-CD16+ precursor giving rise to the same CD94/NKG2C+KIR+CD57+ maturing NK cell progenies. Microarray analysis of NK cell progenies revealed a signature compatible with maturing adaptive NK cells. In vivo circulation of multiple common lymphocyte precursors with rapid development to NKG2C+ NK cell progeny is steadily occurring and may thus be a crucial resource for the prompt control of HCMV. We used microarray to compare the transcriptional profiles of human NKG2C+ NK cells derived from i) CD34+DNAM1brightCXCR4+ precursors, ii) Lin-CD34-CD16+CD56- precursors, iii) peripheral blood.

In vitro differentiated CD56-positive ILC transcriptional profiling via scRNA-seq

Project description:The innate cytotoxic Natural Killer (NK) cells emerged during hematopoiesis through a linear model of human NK development, yet how in vitro model of NK differentiation recapitulates in vivo process is largely under-explored. Here, we established that NK cell trajectory in vitro can be divided into 4 stages by sequential acquisition of CD161, CD56 and CD94 in which CD56 bifurcation can separate Stage 3a (CD56-) as ILC-precursor that can further give rise to stage 3b (CD56+) and stage 4 (CD94+). Re-plating results together with clonal tracing between S3b, S4 and ILC3 subsets supported a diverging developmental point between NK and ILC3 lineages occurs at the S3a stage and accompanied by the loss of the ILC3 potential as NK cell maturation progress from S3b toward S4. Single-cell transcriptomic and RNA-velocity connected the NK cytotoxic trajectory with a coordinated network of transcription factors (TFs) that are highly compatible with primary NK cell gene program.

Gene expression profiling of CD244+CXCR6+ C2 iNKT cell subet and CD244-CXCR6+ C1 iNKT cell subset

Project description:We identified a novel subset of iNKT cells, C2 iNKT cells, that circulate in the periphery. Correspondingly, we characterized the tissue-resident iNKT cell subset, C1 iNKT cells. The development and terminal maturation of C2 iNKT cells completely depended on the thymic epithelial IL-15 niche, whereas C1 iNKT cells were regulated also by local IL-15 niches in peripheral tissues. C2 iNKT cells expressed high levels of genes related to cytotoxicity and exhibited more NK cell-like features. Functionally, C2 iNKT cells regulated self-antigen expression for immune tolerance in the thymus and mediated cancer immunosurveillance in the periphery.

Gene expression profiling of C2, C1 and C0 iNKT cell subset

Project description:We identified a novel subset of iNKT cells, C2 iNKT cells, that circulate in the periphery. Correspondingly, we characterized the tissue-resident iNKT cell subset, C1 iNKT cells. We also found the precursor of these two subsets of iNKT cells, C0 iNKT cells in thymus. The development and terminal maturation of C2 iNKT cells completely depended on the thymic epithelial IL-15 niche, whereas C1 iNKT cells were regulated also by local IL-15 niches in peripheral tissues. C2 iNKT cells expressed high levels of genes related to cytotoxicity and exhibited more NK cell-like features. Here we characterized the C2 iNKT cells, C1 iNKT cells, and C0 iNKT cells using RNA-seq. We also performed RNA-seq for CD4+ T cells, CD8+ T cells and NK cells as a comparison. To investigate the effect of CD4, we performed the RNA-seq for the CD4+ and CD4- C2 iNKT cells.

Epigenetic modification and antibody-dependent expansion of memory-like NK cells in human cytomegalovirus-infected individuals

Project description:As a starting point for exploring potential differences in gene expression between conventional NK and FcRγ-NK cells, and to screen for genes that might contribute to the enhanced CD16 responsiveness of g-NK cells, we performed gene expression profiling studies on sorted samples of NK cells. NKG2C, NCR, and KIR surface receptors were used to separate FcRγ- NK and conventional NK cells.

Epigenetic modification and antibody-dependent expansion of memory-like NK cells in human cytomegalovirus-infected individuals

Project description:As a starting point for exploring potential differences in gene expression between conventional NK and FcRÎ³-NK cells, and to screen for genes that might contribute to the enhanced CD16 responsiveness of g-NK cells, we performed gene expression profiling studies on sorted samples of NK cells. NKG2C, NCR, and KIR surface receptors were used to separate FcRÎ³- NK and conventional NK cells. Indicated subsets of NK cells were sorted from 4 individual donors using a two-way sorter. RNA extracted from the sorted enriched samples were treated with Dnase and analyzed by DNA microarray (Agilent).

CD103+CD56+ ILCs are associated with an immunosuppressed tumour microenvironment

Project description:Immunotherapies have had unprecedented success for multiple cancer types, albeit with variable response rates. Unravelling the complex network of immune cells within the tumour microenvironment (TME) may provide additional insights to enhance anti-tumour immunity and improve clinical response. Here, we identified a CD103-expressing CD56+ ILC subset that were associated with a poor proliferative capacity of tumour-infiltrating lymphocytes (TILs) in culture. We demonstrate that CD103+CD56+ ILCs isolated directly from tumors represent a distinct ILC population that expressed unique surface markers, transcription factor networks, and transcriptomic profiles compared to CD103-CD56+ NK cells. Using multiple approaches, we found that these CD103+CD56+ ILCs were associated with CD8+ T cells with a reduced expression of GZMB. This study identifies 59 a population of CD103+CD56+ ILCs with potentially inhibitory functions, that are associated with a TME that includes CD8+ T cells with poor anti-tumour activity. Further studies focusing on these potentially inhibitory cells may provide insights into understanding the biology of an inhibitory TME.
