Project description:In this study, we aim to establish the means to characterize cynomolgus macaque natural killer (NK) cells, and to investigate the CD27/CD11b NK maturation model in Macaca fascicularis NK cell subpopulations. The NK development studies performed mainly in mice models have demonstrated four functionally distinct subsets as defined by CD27 and CD11b, however this has not yet been established in nonhuman primates. The expression data of these macaque NK subsets will be associated with the antibody-dependent cellular cytotoxicity and missing-self responses produce by each subset.

Project description:Previous reports have defined three subsets of mouse NK cells on the basis of the expression of CD27 and CD11b. The developmental relationship between these subsets was unclear. To address this issue, we evaluated the overall proximity between mouse NK cell subsets defined by CD27 and CD11b expression using pangenomic gene expression profiling. The results suggest that CD27+CD11b-, CD27+CD11b+ and CD27-CD11b+ correspond to three different intermediates stages of NK cell development.

Experiment Overall Design: Spleen cells from RAG-/- mice have been isolated and stained with anti-NK1.1, anti CD27 and anti CD11b antibodies. NK1.1+ cells were sorted into CD27+ CD11b-, CD27+ CD11b+ and CD27- CD11b+ subsets by flow cytometry. There are two independent replicates for each sample. Total RNA was extracted with the RNeasy microkit (Qiagen) and gene expression profiles were performed according to manufacturer instructions (Affymetrix mouse 430 2.0).

Project description:The cell lineage origin of interferon-producing killer dendritic cells (IKDC), which exhibit prominent anti-tumoral activity, has been subject to debate. Although IKDC were first described as a cell type exhibiting both pDC and NK cell properties, the current view reflects that IKDC merely represent activated NK cells expressing B220, which were thus renamed B220+ NK cells. Herein, we further investigate the lineage relationship of B220+ NK cells with regards to other NK cell subsets. We surprisingly find that, upon adoptive transfer, B220- NK cells did not acquire B220 expression, even in the presence of potent activating stimuli. These findings strongly argue against the concept that B220+ NK cells are activated NK cells in vivo. Moreover, we unequivocally demonstrate that B220+ NK cells are highly proliferative and differentiate into mature NK cells upon in vivo adoptive transfer. Additional phenotypic, functional and transcriptional characterizations further define B220+ NK cells as immediate precursors to mature NK cells. By analogy to pre-B cells and pre-DC, we propose that B220+ NK cells should be renamed pre-NK cells. The characterization of these novel attributes to pre-NK cells will guide the identification of their ortholog in humans, contributing to the design of potent cancer immunotherapies. Total RNA from B220+ NK cells compared to total RNA from CD27- and CD27+ NK cell subsets all isolated ex vivo from the spleen of B6.Rag-/-. Triplicatas were analysed.

Project description:It is known that NK cells are a heterogeneous population of functionally distinct NK cell subsets. Here we report on different genomic, phenotypic and functional properties of four murine NK cell subsets distinguished by CD117 (c-kit), CD27 and CD11b expression.

Here we report on different genomic, phenotypic and functional properties of four murine NK cell subsets distinguished by CD117 (c-kit), CD27 and CD11b expression. Gene expression was measured in NK cell subsets freshly sorted from murine C57Bl/6 splenocytes. Two to three different batches were analysed.

Project description:NK cells develop in the bone marrow and complete their maturation in peripheral organs, but the molecular events controlling maturation are incompletely understood. Utilizing an NK cell-specific miR-15/16 deficient genetic model (15aKO), we identified a critical role for miR-15/16 family microRNAs in the normal maturation of NK cells in vivo, with a specific reduction in mature CD11b+CD27- NK cells in multiple tissues. The mechanism responsible was a block in differentiation, since accelerated NK cell death was not evident, and earlier intermediates of NK cell maturation were expanded. Further, we identified Myb as a direct target of miR-15/16 in NK cells, with Myb expression increased in immature 15aKO NK cells. Following adoptive transfer, immature 15aKO NK cells exhibited defective maturation, which was rescued by ectopic miR-15/16 expression or Myb knockdown. Moreover, Myb overexpression resulted in defective NK cell maturation. Thus, miR-15/16 regulation of Myb controls the normal NK cell maturation program. 3 technical replicates each of CD27+ 15a/16-1FKO NK cells, and CD27+ Ctrl NK cells

Project description:All innate lymphoid cells (ILC) constitutively express and require the small helix-loop-helix protein ID2 but the functions of ID2 are not well understood in these cells. Here we show that natural killer (NK) cells, the prototypic ILC, can develop in the absence of ID2 but lose their innate properties and remain as CD27+CD11b- cells that fail to mature into cytotoxic effectors. We show that ID2 broadly limited chromatin accessibility at E protein binding sites near T lymphocyte-associated genes including multiple chemokine receptors, cytokine receptors, and signaling molecules. Moreover, ID2 prevented the conversion of CD27+CD11b- NK cells from a CD8 memory precursor-like chromatin accessibility state toward a naïve-like chromatin accessibility state, and altered their functional capacity. Finally, we demonstrate that increased expression of the naïve T cell-associated helix-loop-helix protein ID3 was required for development of ID2-deficient NK cells, indicating that completely unfettered E protein function is incompatible with NK cell development. These data solidify the roles of ID2 and ID3 as mediators of effector and naïve gene programs, respectively, and revealed a critical role for ID2 in promoting a chromatin state and transcriptional program in CD27+CD11b- NK cells that supports the innate properties of these cells and their ability to undergo cytotoxic effector differentiation.
