Transcriptional profiling of NK cells sorted from lungs and axillary LNs from Cdh1F/F;Trp53F/F;Foxp3GFP-DTR mice bearing 100mm2 orthotopically transplanted mammary tumors, treated with difteria toxin (DT) or PBS [NK]

ABSTRACT: We studied the impact of DT treatment (Treg depletion) on NK cells (CD3-, NKp46+, DX5+) in axillary TDLNs and lungs of tumor bearing Foxp3GFP-DTR mice . Here we generated RNAseq data from sorted NK cells from DT or PBS treated Foxp3GFP-DTR mice bearing 100mm2 mammary tumors from lungs, axillary TDLNs

Gene expression profiling of murine liver NK cells

Project description:The NK cell pool is composed of distinct NK cell subsets with divergent phenotypic and functional features. In order to determine whether DX5- and DX5+ NK cells from murine livers represent different NK cell subsets, DX5- and DX5+ liver NK cells of adult mice were respectively sorted for gene expression analysis using the Affymetrix GeneChip Mouse Genome 430 2.0 arrays. DX5-NK1.1+CD3- cells and DX5+NK1.1+CD3- cells were sorted from the liver of naive B6 wild-type mice. RNA of each sample was then extracted and hybridized on Affymetrix microarrays to detail differences between DX5- and DX5+ liver NK cells in gene expression.

Expression data from WT liver DX5- NK cells and dnTGFbRII liver DX5- NK cells

Project description:Liver is a unique immunological organ containing large number of NK cells which play an important role in the maintenance of liver homeostasis, especially the specific liver resident DX5- NK cell subset. We used microarrays to detail the differences of normal DX5- NK cells and the DX5- NK cells in inflammatory environment.

Tissue-Resident Natural Killer (NK) Cells Are Cell Lineages Distinct From Thymic and Conventional Splenic NK Cells (part 2)

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 DX5-CD49+, liver DX5+CD49-, spleen DX5+ 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

ScRNA-seq of stromal cells in WT and LRRC15 DTR mice

Project description:KPR tumors were subcutaneously implanted in Lrrc15DTRGFPwt/wt (DTR–) or Lrrc15DTRGFPwt/ki (DTR+) mice and DT treatment was initiated in both DTR– and DTR+ mice when tumors reached a mean volume of 100-200mm3. scRNAseq of CD24-CD45- stromal cells from a total of 40 tumor-bearing animals across both DTR– and DTR+ genotypes was carried out at four different time points including 10 days post tumor implantation and immediately prior to initiation of DT treatment (IOT) (referred to as day 0) and on days 7, 14, and 21 post IOT.

Transcriptional profiling of senescent cell-associated genes in adult mouse lung.

Project description:To evaluate the senescent cell-dependent gene expression in aged lung tissue, young (2mo) ARF-DTR mice and adult (12mo) ARF-DTR mice treated with PBS or DT every two weeks up to 1 month were analyzed using the Agilent Technologies SurePrint G3 Mouse Gene Expression Microarray. Gene expression in lungs of ARF-DTR mice (2mo, 12mo, 12mo+DT) was analyzed. WT mice was used to evaluate the transgene-independent effect of DT on gene expression.

Acute lung injury models identify putative growth factors that promote tissue repair and biomarkers for acute lung injury

Project description:We tried to identify growth factor(s) to promote regeneration of type 2 alveolar epitherial cells. To identify such candidates, we compared gene expression profiles of RNAs from lungs of mice of the following four different groups of bone marrow (BM) chimeric mice after diphteria toxin (DT) injection. LL, BM cells of LysM-DTR mice into LysM-DTR mice; WL, BM cells of wild-type mice into LysM-DTR mice; LW, BM cells of LysM-DTR mice into wild-type mice; WW, BM cells of wild-type mice into wild-type mice. Transcriptome analysis revealed that a set of growth factor-related genes was upregulated in the lungs of WL mice compared to LL mice.

Transcriptional profile of injured hearts treated with the cholinesterase inhibitor pyridostigmine (PYR) at Day 5

Project description:It has been shown that acetylcholine has anti-inflammatory properties. The aim of this study is to investigate the role of acetylcholine in cardiac inflammation. We used the diphtheria toxin (DT)-cardiomyocyte ablation model (DTR model) (Lavine et al., 2014 - PNAS) to induce cardiac injury (DT, 2 days, 2.5µg/kg, IP). Beginning one week prior to DT injury, mice were treated with vehicle (PBS, phosphate buffered saline) or the cholinesterase inhibitor pyridostigmine (PYR, 3mg/kg, SQ). Hearts were harvested at Day 5 post-DT-injury. Here, we provide the transcriptional profile of wild-type/PBS, wild-type/PYR, DTR/PBS and DTR/PYR hearts.
