Project description:This study shows that liver Eomes- NK cells are not precursors of classical Eomes+ NK cells but rather constitute a distinct lineage of innate lymphoid cells. Gene profile analyses show that Eomes- NK cells share part of their transcriptional program with NKT cells that includes genes involved in liver homing, NK cell receptors, and several cytokines and cytokine receptors. Eomes- NK cells, Eomes+ Nk cells and NKT cells were sorted by flow cytometry from Eomes-GFP reporter mice. Total RNA was extracted and hybridized to Affymetrix microarrays.

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.
Project description:CD1d-dependent type I NKT cells, which are activated by lipid antigen, are known to play important roles in innate and adaptive immunity, as are a portion of type II NKT cells. However, the heterogeneity of NKT cells, especially NKT-like cells, remains largely unknown. Here, we report the profiling of NKT (NK1.1+CD3e+) cells in livers from wild type (WT), Jα18-deficient and CD1d- deficient mice by single-cell RNA sequencing. Unbiased transcriptional clustering revealed distinct cell subsets. The transcriptomic profiles identified the well-known CD1d-dependent NKT cells and defined two CD1d-independent NKT cell subsets. In addition, validation of marker genes revealed the differential organ distribution and landscape of NKT cell subsets during liver tumor progression. More importantly, we found that CD1d-independent Sca-1−CD62L+ NKT cells showed a strong ability to secrete IFN-γ after costimulation with IL-2, IL-12 and IL-18 in vitro. Collectively, our findings provide a comprehensive characterization of NKT cell heterogeneity and unveil a previously undefined functional NKT cell subset.

Project description:PURPOSE: To provide a detailed gene expression profile of the normal postnatal mouse cornea. METHODS: Serial analysis of gene expression (SAGE) was performed on postnatal day (PN)9 and adult mouse (6 week) total corneas. The expression of selected genes was analyzed by in situ hybridization. RESULTS: A total of 64,272 PN9 and 62,206 adult tags were sequenced. Mouse corneal transcriptomes are composed of at least 19,544 and 18,509 unique mRNAs, respectively. One third of the unique tags were expressed at both stages, whereas a third was identified exclusively in PN9 or adult corneas. Three hundred thirty-four PN9 and 339 adult tags were enriched more than fivefold over other published nonocular libraries. Abundant transcripts were associated with metabolic functions, redox activities, and barrier integrity. Three members of the Ly-6/uPAR family whose functions are unknown in the cornea constitute more than 1% of the total mRNA. Aquaporin 5, epithelial membrane protein and glutathione-S-transferase (GST) omega-1, and GST alpha-4 mRNAs were preferentially expressed in distinct corneal epithelial layers, providing new markers for stratification. More than 200 tags were differentially expressed, of which 25 mediate transcription. CONCLUSIONS: In addition to providing a detailed profile of expressed genes in the PN9 and mature mouse cornea, the present SAGE data demonstrate dynamic changes in gene expression after eye opening and provide new probes for exploring corneal epithelial cell stratification, development, and function and for exploring the intricate relationship between programmed and environmentally induced gene expression in the cornea.
