Expression data from CD1d tetramer-sorted b-GL122/LGL1âspecific human T cells or iNKT cells

ABSTRACT: The ability to detect and isolate bGL1-22/LGL1âspecific human type II NKT cells allowed us to compare the global gene expression profiles of these cells with type I NKT cells using microarray analysis. Principal component analysis revealed that the gene expression profile signature for bGL1-22 and LGL1-specific T cells both before and after activation with anti-CD3/CD28 beads is distinct from that of type I NKT cells. RNA from CD1d tetramer-sorted b-GL122/LGL1âspecific T cells or iNKT cells was amplified, labeled, and hybridized on the Affymetrix Human Genome U133 Plus 2.0 microarray chips. The data were analyzed with GeneSpring GX 12.5 (Agilent Technologies)

Chronic inflammation including B-cell activation is commonly observed in both inherited (Gaucher disease [GD]) and acquired disorders of lipid metabolism. However, the cellular mechanisms underlying B-cell activation in these settings remain to be elucidated. Here, we report that β-glucosylceramide 22:0 (βGL1-22) and glucosylsphingosine (LGL1), 2 major sphingolipids accumulated in GD, can be recognized by a distinct subset of CD1d-restricted human and murine type II natural killer T (NKT) cells. ...[more]

Gene expression comparison of wild-type and IL15ko thymic NKT cells

Project description:Semi-invariant natural killer T (NKT) cells are thymus-derived innate lymphocytes that modulate microbial and tumour immunity as well as autoimmune diseases. These immunoregulatory properties of NKT cells are acquired during their development. Much has been learnt regarding the molecular and cellular cues that promote NKT cell development, yet how these cells are maintained in the thymus and the periphery and how they acquire functional competence are incompletely understood. We found that IL-15 induced several Bcl-2 family survival factors in thymic and splenic NKT cells in vitro. Yet, IL15-mediated thymic and peripheral NKT cell survival critically depended on Bcl-xL expression. Additionally, IL-15 regulated thymic developmental stage 2 (ST2) to ST3 lineage progression and terminal NKT cell differentiation. Global gene expression analyses and validation revealed that IL-15 regulated Tbx21 (T-bet) expression in thymic ST3 NKT cells. The loss of IL15-dependent T-bet expression resulted in poor expression of IFN-γ and several NK cell receptors in NKT cells. Taken together, our findings reveal a critical role for IL-15 in NKT cell survival, which is mediated by Bcl-xL, and effector differentiation, which is regulated by T-bet. Gene expression was measured in NKT cells sorted from pooled thymi of wild-type (3 replicates) or IL-15 deficient (2 replicates) mice.

Microarray expression profiling of NKT and MAIT subsets in different organs of B6-MAIT/CAST mice.

Project description:MAIT cells (MAITs) represent an abundant T lymphocyte subset with unique specificity for microbial metabolites presented by the MHC-1b molecule, MR1. MAIT conservation along evolution indicates important, non-redundant functions, but their low frequency in mice has hampered their detailed characterization. Here, we performed a transcriptomic analysis of murine MAITs in comparison with NKT subsets and with mainstream T cells in spleen and peripheral organs of B6-MAIT/CAST mice expressing a Rorc-GFP transgene. MAIT and NKT cells have been FACS-sorted after tetramer staining (MR1:5-OP-RU Tet+ for MAIT, CD1d:PBS57Tet+ for NKT), and 1/17 subsetting based on the expression of Rorc.

Effect of Th-POK deficiency on global gene expression in liver Va14i NKT cells

Project description:We sought to identify genes regulated by the transcription factor Th-POK (Zbtb7b) in liver Va14i NKT cells, by RNA microarray analysis of global gene expression in Va14i NKT cells from mice homozygous for the Th-POK-inactivating hd point mutation as compared with the same cell population isolated from heterozygous or wild-type age-matched mice. Two sample set pairs of hd/hd and either hd/+ or +/+ age-matched Va14i NKT cells were prepared via magnetic selection and cell sorting, and total RNA prepared using a Qiagen Rneasy mini kit. IVT probe generation and hybridization to Affymetrix Mouse Genome 430 2.0 arrays was carried out by the Veterans Medical Research Foundation GeneChipTM Microarray located at UCSD.

NKT-10 cells represent a novel invariant NKT cell subset with regulatory characteristics

Project description:We compared splenic Va14i NKT cells from C57BL/6 control mice and from mice injected 4 weeks earlier intravenously with 4ug/mouse of the iNKT cell antigen alpha-galactosylceramide (aGalCer). These mice were either left unstimulated or were stimulated with 1ug/mouse aGalCer i.v.. All mice were female and 8 weeks of age at the beginning of the experiment. Va14i NKT cells were enriched via magnetic selection and cell sorted for TCRb+ CD1d/aGalCer-tetramer+. Total RNA were prepared using a Qiagen RNeasy mini kit. IVT probe generation and hybridization to Affymetrix Mouse Genome 430 2.0 arrays was carried out by the Veterans Medical Research Foundation GeneChipTM Microarray located at UCSD. Group 1 (Ctr_unstim) = iNKT cells from C57BL/6 control mice and left unstimulated / Group 2 (Ctr_stim) = iNKT cells from C57BL/6 control mice and injected 1h before purification with 1ug aGalCer i.v. / Group 3 (Pre_unstim) = iNKT cells from C57BL/6 mice injected 4weeks earlier with 4ug aGalCer i.v. and left unstimulated / Group 4 (Pre_stim) = iNKT cells from C57BL/6 mice injected 4weeks earlier with 4ug aGalCer i.v. and injected 1h before purification with 1ug aGalCer i.v. / Sample were prepared in duplicates in two independent experiments.

Gene Expression Profiling of human monocytes: Combination Therapy with AntiâCTLA-4 and AntiâPD-1 Leads to Distinct Immunologic Changes In Vivo

Project description:Transcriptome analysis of human peripheral blood monocytes Combination therapy concurrently targeting PD-1 and CTLA-4 immune checkpoints leads to remarkable antitumor effects. Although both PD-1 and CTLA-4 dampen the T cell activation, the in vivo effects of these drugs in humans remain to be clearly defined. To better understand biologic effects of therapy, we analyzed blood/tumor tissue from patients undergoing single or combination immune checkpoint blockade. We show that blockade of CTLA-4, PD-1, or combination of the two leads to distinct genomic (changes in gene-expression profile) and functional signatures in vivo in purified human T cells and monocytes. RNA extracted from freshly isolated monocytes from peripheral blood of patients treated with either antiâPD-1 (n = 6), antiâCTLA-4 (n = 5), Combo therapy with antiâPD-1 and antiâCTLA-4 concurrently (Combo, n = 6), and Seq antiâPD-1 in patients with prior antiâCTLA-4 (Seq, n = 3) was analyzed using the Affymetrix GeneChip Human Transcriptome 2.0 exon array. No techinical replicates were performed.

Expression data comparing PLZF+/+, PLZF +/lu, PLZF lu/lu gammadelta NKT cells

Project description:Natural killer (NKT) T cells exhibit tissue distribution, surface phenotype, and functional responses that are strikingly different from those of conventional T cells. The transcription factor PLZF is responsible for most of these properties, as its ectopic expression in conventional T cells is sufficient to confer to them an NKT-like phenotype. The molecular program downstream of PLZF, however, is largely unexplored. Here we report that PLZF regulates the expression of a surprisingly small set of genes, many with known immune functions. This includes several established components of the NKT cell developmental program. Transcriptional program downstream of PLZF in gammadelta NKT cells was analyzed by comparing wt, heterozygous and PLZF-deficient gammadelta NKT cells
