Project description:T cells were extracted from spleens of CBLA mice and activated in vitro with CD3/28 on day 0. They were spinoculated with retroviruses overexpressing a gene of interest on day 1. On day 4, BFP-positive (infected) cells were FACS sorted and measured by a variant of SMART-seq2
Project description:To identify potential functional roles of liver-resident NK cells we performed RNA sequencing on FACS sorted NK cell subpopulations from liver perfusates (n=5) and healthy blood controls (n=5). Full-length transcripts were sequenced from low-input samples using a modified version of the SMART-Seq2 protocol. Hepatic CD56brightCD16- and CD56brightCD16+ samples upregulate genes associated with tissue residency.
Project description:To describe the protein profile in hippocampus, colon and ileum tissue’ changing after the old faeces transplants, we adopted a quantitative label free proteomics approach.
Project description:To investigate the transcriptional profile of human circulating T cells with skin tissue-resident memory phenotype (cTRM) in GVHD we performed bulk RNA sequencing from SMART-seq2 of sorted human cTRM (CD3+ CD4+ CLA+ CD103+) and conventional T cells (CD3+ CD4+ CD103-), and single cell RNA sequencing from 10X Genomics of sorted human CD45+, both from isolated blood PBMCs of patients with active acute GVHD.
Project description:Macrophages are hematopoietic cells critical for innate immune defense, but also control organ homeostasis in a tissue-specific manner. Tissue-resident macrophages, therefore, provide a well-defined model to study the impact of ontogeny and microenvironment on chromatin state. Here, we profile the dynamics of four histone modifications across seven tissue-resident macrophage populations, as well as monocytes and neutrophils. We identify 12,743 macrophage-specific enhancers and establish that tissue-resident macrophages have distinct enhancer landscapes. Our work suggests that a combination of tissue and lineage-specific transcription factors form the regulatory networks controlling chromatin specification in tissue-resident macrophages. The environment has the capacity to alter the chromatin landscape of macrophages derived from transplanted adult bone marrow in vivo and even differentiated macrophages are reprogrammed when transferred into a new tissue. Altogether, these data provide a comprehensive view of macrophage regulation and highlight the importance of microenvironment along with pioneer factors in orchestrating macrophage identity and plasticity. 7 tissue-resident macrophage populations were isolated, as well as monocytes and neutrophils, and transcriptome analysis was performed. Experiment was done in duplicates.
