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

Most studies of mouse NK cells, however, have focused on conventional NK (cNK) cells in the spleen. Recently, we described two populations of liver NK cells, tissue-resident NK (trNK) cells and those resembling splenic cNK cells. However, their lineage relationship was unclear; trNK cells could be developing cNK cells, related to thymic NK cells, or a lineage distinct from both cNK and thymic NK cells. Herein we used detailed transcriptomic, flow cytometric, and functional analysis and transcription factor-deficient mice to determine that liver trNK cells form a distinct lineage from cNK and thymic NK cells. Taken together with analysis of trNK cells in other tissues, there are at least four distinct lineages of NK cells: cNK, thymic, liver (and skin) trNK, and uterine trNK cells.

Project description:To understand the mechanism of the defective NK cell functions with MYC deficiency, we isolated splenic NK cells (CD3-NK1.1+CD49b+) from Mycf/f and MycΔ/Δ/Ncr1Cre mice and performed RNA-seq analysis. It revealed that ribosome and natural killer cell-mediated cytotoxicity were the two most enriched pathways in the differentially down-regulated genes. Functional studies showed reduced synthesis of NK cell effector molecules in the NK Cells with MYC deficiency. Collectively, these data suggest impaired ribosomal biogenesis and reduced synthesis of cytotoxic molecule in the NK cells with MYC deficiency.
