Single cell RNA-seq of HLA-E restricted UL40-specific T cells

ABSTRACT: Human cytomegalovirus infection (CMV) can stimulate robust human leukocyte antigen (HLA)-E restricted CD8 T cell responses. These T cells recognize a peptide from UL40, which differs by as little as a single methyl group from self-peptides that also bind HLA-E, challenging their capacity to avoid self-reactivity. We showed in one donor 2 distinct populations of UL40/HLA-E T cells, with vastly different T cell receptor (TCR) affinities for the UL40/HLA-E complex. However, paradoxically, lower cytokine responses were observed from UL40/HLA-E T cells bearing TCRs with high affinity for HLA-E. To identify why these T cells bearing high affinity T cell receptors were less responsive to antigens, we performed single cell RNAseq analysis. These 2 distinct populations of T cells were single-cell sorted into 96-well plates prior to single cell RNA-seq analysis.

Single cell RNA-seq of human CD8+ T cells binding the IAV HLA-A24/PB1 498-505 tetramer

Project description:PBMCs from 4 donors were stained with the influenza A virus HLA-A24/PB1 498-505 tetramer. Two donors (non-LIFT8 and non-LIFT12) showed TCR independent KIR binding to tetramers whereas the other two donors (Non-LIFT14 and Non-LIFT10) showed TCR specific binding. Cells were single-cell sorted on a BD Aria III into 96-well plates containing 0.5 μl dNTP mix (10 mM), 0.5 μl oligo-dT pri- mer (5 μM), and 1 μl lysis buffer (prepared by adding 1 μl RNase inhibitor to 19 μl Triton X-100 solution, 0.2% v/v).

Gene expression comparison of wild-type and IL15ko thymic NKT cells

Project description:Semi-invariant natural killer T (NKT) cells are thymus-derived innate lymphocytes that modulate microbial and tumour immunity as well as autoimmune diseases. These immunoregulatory properties of NKT cells are acquired during their development. Much has been learnt regarding the molecular and cellular cues that promote NKT cell development, yet how these cells are maintained in the thymus and the periphery and how they acquire functional competence are incompletely understood. We found that IL-15 induced several Bcl-2 family survival factors in thymic and splenic NKT cells in vitro. Yet, IL15-mediated thymic and peripheral NKT cell survival critically depended on Bcl-xL expression. Additionally, IL-15 regulated thymic developmental stage 2 (ST2) to ST3 lineage progression and terminal NKT cell differentiation. Global gene expression analyses and validation revealed that IL-15 regulated Tbx21 (T-bet) expression in thymic ST3 NKT cells. The loss of IL15-dependent T-bet expression resulted in poor expression of IFN-γ and several NK cell receptors in NKT cells. Taken together, our findings reveal a critical role for IL-15 in NKT cell survival, which is mediated by Bcl-xL, and effector differentiation, which is regulated by T-bet. Gene expression was measured in NKT cells sorted from pooled thymi of wild-type (3 replicates) or IL-15 deficient (2 replicates) mice.

Single-cell RNA sequencing of spleen-derived LCK-expressing cells from adult zebrafish

Project description:Transcriptome data from individual lck:GFP expressing cells isolated from spleens of two adult Zebrafish. LCK is a marker of lymphocytes and here we identified two major subpopulations corresponding to T-cells and NK-like and a minor one of myeloid-like cells. Single cell transcriptomes are matched with FACS index sorting data (GFP, forward and side light scatter and dead cell staining)

Single cell RNA-sequencing of E8.5 stage embryonic neural tissue from mouse

Project description:We describe a so far uncharacterized, embryonic and self-renewing Neural Plate Border Stem Cell (NBSC) population with the capacity to differentiate into central nervous and neural crest lineages. NBSCs can be obtained by neural transcription factor-mediated reprogramming (BRN2, SOX2, KLF4, and ZIC3) of human adult dermal fibroblasts and peripheral blood cells (induced Neural Plate Border Stem Cells, iNBSCs) or by directed differentiation from human induced pluripotent stem cells (NBSCs). Moreover, human (i)NBSCs share molecular and functional features with primary Neural Plate Border Stem Cells (pNBSCs) isolated from neural folds of E8.5 mouse embryos. Here we provide single cell RNA-sequencing data of neural tissue derived from two E8.5 mouse embryos. After manual isolation and enzymatic separation E8.5 neural tissue was single cell sorted and RNA sequencing was performed following the Smart-seq2 protocol. In sum, cultured pNBSCs and E8.5 neural tube cells share a similar regional identity and expression signature suggesting that pNBSCs might correspond to an endogenous progenitor in this area of the developing brain.

Single cell RNA-sequencing of primary mouse Neural Plate Border Stem Cells

Project description:We describe a so far uncharacterized, embryonic and self-renewing Neural Plate Border Stem Cell (NBSC) population with the capacity to differentiate into central nervous and neural crest lineages. NBSCs can be obtained by neural transcription factor-mediated reprogramming (BRN2, SOX2, KLF4, and ZIC3) of human adult dermal fibroblasts and peripheral blood cells (induced Neural Plate Border Stem Cells, iNBSCs) or by directed differentiation from human induced pluripotent stem cells (NBSCs). Moreover, human (i)NBSCs share molecular and functional features with an endogenous NBSC population isolated from neural folds of E8.5 mouse embryos. Upon differentiation, iNBSCs give rise to either (1) radial glia-type stem cells, dopaminergic and serotonergic neurons, motoneurons, astrocytes, and oligodendrocytes or (2) cells from the neural crest lineage. Here we provide single cell RNA-sequencing data of two primary mouse Neural Plate Border Stem Cell Lines (pNBSCs). pNBSCs were single cell sorted and RNA sequencing was performed following the Smart-seq2 protocol. In sum, pNBSCs and iNBSCs share a similar regional identity, expression signature and analogous differentiation dynamics on the single-cell-level, suggesting the presence of a transient, NBSC-like progenitor during the neurulation stage of mouse and likely also human embryos.

Single cell RNA seq of influenza tetramer specific CD8+ T cells from baseline, acute and long term memory timepoints

Project description:The aim of the experiment was to assess the differentiation and activation status of influenza-specific CD8+ T cells (A2/PB1 413 and A2/BHA 543) from an individual naturally infected with influenza B (PCR-confirmed). Single tetramer+ CD8+ T cells from tetramer-enriched PBMCs were sorted from baseline (~3 months before infection), at 14 days after infections, at 3 months after infection and at 1.5 years after infection. Libraries were prepared using a modified Smart-seq2 protocol as detailed in the methods section of the manuscript.

Effects of HLA DRB1*15:01 interactions with ⍺-syn32-46 on gene expression in intestinal immune cells in mice

Project description:HLA DRB1*15:01 is overrepresentated in Parkinson's disease patients and binds with high affinity to the ⍺-synuclein peptide, 32-46. Immunization of humanized mice expressing HLA DRB1*15:01 with ⍺-syn32-46 induces enteric phenotypes similar to those of prodromal Parkinson's disease. We collected the small intestines from HLA mice immunized with either Complete Freund's Adjuvant (CFA) with ⍺-syn32-46 or CFA alone, sorted the CD45+ immune cells, then performed single-cell RNA sequencing to evaluate gene expression at single cell resolution.
