Transcriptional Reference Map of Human Natural Killler Cells

ABSTRACT: The functional diversity of NK cell repertoires stems from differentiation, homeostatic receptor-ligand interactions, and adaptive-like responses to viral infections. Here we performed single-cell RNA sequencing of both bulk NK and sorted NK subsets to establish a transcriptional reference map of human natural killer cells based on single-cell RNA sequencing profiles from 72,129 cells obtained from bulk (12 donors) and sorted phenotypically-defined NK cell subsets (2 donors) and tissue-resident NK cells (TrNK, 136 donors). Our own data is included here.

Bulk RNA-seq and ATAC-seq of mouse uterine tissue-resident natural killer cells.

Project description:Uterine natural killer(NK) cells play a crucial role in pregnancy by promoting spiral artery remodeling and secreting fetal growth factors.Uterine trNK cells before pregnancy and during pregnancy (gd6.5, gd8.5 and gd11.5) were sorted, then applied into bulk RNA-sequence to reveal the features at different timepoints. Similarily, uterine trNK cells with different treatment in vitro were also sorted for bulk RNA-sequence to identify the role of IL-21-STAT3 signaling. To interpret the differentiation trajectory of uterine trNK cells, CD45+NKp46+NK1.1+ cells in wild-type virgin mice, wild-type gd8.5 mice, Il21r-/- gd8.5 mice and Il21r-/- gd8.5 mice with Caspase3 inhibitor are sorted.Applying them to Single-Cell RNA sequence, a differentiation trait of uterine NK cells during pregancy was revealed and IL-21 significantly promoted this process at initial stage.

Tissue-Resident Natural Killer (NK) Cells Are Cell Lineages Distinct From Thymic and Conventional Splenic NK Cells (part 1)

Project description:Natural killer (NK) cells belong to the innate immune system where they can control virus infections and developing tumors by cytotoxicity and production of inflammatory cytokines. Most studies of mouse NK cells, however, have focused on conventional NK (cNK) cells found in the spleen. Recently, we described two populations of NK cells within the liver, tissue-resident NK (trNK) cells and those resembling splenic cNK cells. However, the lineage relationship of trNK to cNK cells was unclear because trNK cells display a phenotype associated with immature, developing cNK cells. Moreover, liver trNK cells could be related to thymic NK cells or alternatively, a lineage distinct from both cNK and thymic NK cells. Herein we used detailed transcriptomic, flow cytometric, and functional analysis of mice deficient in several transcription factors to determine that liver trNK cells form a distinct lineage from cNK and thymic NK cells, especially because they do not require NFIL3 (E4BP4), the previously described NK cellspecification factor. Analysis of other tissues indicate the presence of trNK cells in skin and uterus with different transcription factor requirements. Thus, there are at least four distinct lineages of NK cells: cNK, thymic, liver (and skin) trNK, and uterine trNK cells. Liver NK 1.1+CD49+, liver NK 1.1+CD49-, spleen NK 1.1+ CD49- populations of NK cells were sorted with FACS pooling cells from individual mice to end up with ~100k cells for each samples. mRNA was derived from lysates using Invitrogen oligo-dT beads

CMV infection drives adaptive epigenetic diversification of NK cells

Project description:The mechanisms underlying human NK cell phenotypic and functional heterogeneity are unknown. Here, we describe the emergence of diverse subsets of human NK cells selectively lacking expression of signaling proteins following cytomegalovirus (CMV) infection. The absence of B and myeloid cell-related signaling protein expression in these NK cell subsets correlated with promoter DNA hypermethylation. Intriguingly, geneome-wide analyses revealed patterns of DNA methylation that were strikingly similar between CMV-associated adaptive NK cells and cytotoxic effector CD8+ T cells, but differed from those of canonical NK cells. A total of 23 samples were analyzed (4 sorted NK cell subsets and 2 sorted T cell subsets each from 4 individual donors). In one donor only 5 subsets were analyzed. Bisulfite-converted genomic DNA was hybridized to the Illumina Human Methylation450 BeadChip

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).

Project description:Here we performed single-cell RNA sequencing to address repertoire stability and subset plasticity during IL-15 driven homeostatic proliferation. Sorted NK cell subsets representing discrete stages of NK cell differentiation are compared with the corresponding subsets after proliferation and further sorted into two subsets depending on the rate of proliferation.

Autocrine TGF-β1 drives tissue-specific differentiation and function of resident NK cells

Project description:Group 1 innate lymphoid cells (ILCs) encompass NK cells and ILC1s which have non-redundant roles in host protection against pathogens and cancer. Despite their circulating nature, NK cells can establish residency in selected tissues during ontogeny, forming a distinct functional subset. The mechanisms that initiate, maintain, and regulate the conversion of NK cells into tissue-resident NK (trNK) cells are currently not well understood. Here, we identify autocrine transforming growth factor-b (TGF-b) as a cell-autonomous driver for NK cell tissue-residency across multiple glandular tissues during development. Cell-intrinsic production of TGF-β was continuously required for the maintenance of trNK cells and synergized with Hobit to enhance cytotoxic function. Whereas autocrine TGF-β was redundant in tumors, our study revealed that NK cell-derived TGF-β allowed expansion of cytotoxic trNK cells during local infection with murine cytomegalovirus (MCMV) and contributed to viral control in the salivary gland. Collectively, our findings reveal tissue-specific regulation of trNK cell differentiation and function by autocrine TGF-β1, which is relevant for anti-viral immunity.
