A single-cell atlas of lymphocyte adaptive immune repertoires and transcriptomes reveals age-related differences in convalescent COVID-19 patients

ABSTRACT: We utilize single-cell sequencing (scSeq) of lymphocyte immune repertoires and transcriptomes to quantitatively profile the adaptive immune response in COVID-19 patients of varying age. Our scSeq analysis defines the adaptive immune repertoire and transcriptome in convalescent COVID-19 patients and shows important age-related differences implicated in immunity against SARS-CoV-2.

Single cell RNA, BCR and CITE-Seq of longitudinal COVID-19 patients

Project description:6 patients with severe COVID-19 were followed longitudinally during hospitalization and up to 1 year after infection, when they also received a vaccine. For each time point and patient, PBMCs were collected and split into 3 pools: 1/3 was sequenced straight; from 1/3 of the samples B cells were enriched (B cell enrichment kit from StemCell) and from 1/3 of the samples, antigen-specific cells were sorted using barcoded N, S and RBD probes. All samples were further stained using a cocktail of 181 barcoded Abs. For all samples we have sequences gene-expression, B cell receptor and Cell surface proteins.

Single cell antigen receptor analysis reveals lymphocyte developmental origins

Project description:To test the impact of nonsense-mediated decay (NMD) on BCR/TCR RNA sequences, we treated peripheral blood mononuclear cells (PBMCs) with cycloheximide to block NMD and analyzed treated and untreated cells by scRNA-seq with scVDJ-seq.

Somatic Gain-of-Function mTOR mutation in Clonally Expanded T-lymphocytes Associated with Chronic Graft-Versus-Host Disease

Project description:Graft-versus-host-disease (GvHD) is the main complication of allogeneic hematopoietic stem cell transplantation (HSCT). Here we report studies of a patient with chronic GVHD (cGVHD) carrying persistent CD4+ T cell clonal expansion which harbored somatic mTOR, NFKB2, and TLR2 mutations. Functional analysis of the discovered mTOR mutation indicated a gain-of-function alteration and activation of both mTORC1 and mTORC2 signaling pathways leading to increased cell proliferation and decreased apoptosis. Single-cell RNA sequencing and real-time impedance measurements supported increased cytotoxicity of mutated CD4+ T cells. High throughput drug-sensitivity testing suggested mutations induce resistance to mTOR inhibitors but increase sensitivity for HSP90 inhibitors. Our findings suggest that somatic mutations may contribute to aberrant T cell proliferations and participate in the persistent immune activation in cGVHD paving the way for novel targeted therapies.

Somatic mutations in lymphocytes in patients with immune-mediated aplastic anemia

Project description:In this study, we investigated somatic mutations of CD4+ and CD8+ T cells in patients with immune-mediated aplastic anemia (AA). To understand the role of mutations, we performed single-cell level analysis of 6 longitudinal samples of 2 AA patients carrying STAT3 or KRAS and other mutations in CD8+ T cells. The analysis was performed using V(D)J and 5' gene expression platform (10X Genomics). STAT3 mutated clone was clearly distinguishable from other CD8+ T cells and showed a cytotoxic phenotype, attenuated by successful immunosuppressive treatment. Our results suggest that somatic mutations in T cells can alter T cell phenotype warranting further investigation of their role in the pathogenesis of immune-mediated AA.

Project description:To characterize the consequences of systemic IL-27R agonism via IL-27 overexpression or IL-27 blockade (αIL-27) on anti-tumor CTL, we performed scRNA-seq of M86 neoantigen-specific CD8+ T cells from MC38 tumors and dLN.

Loss of apelin blocks the emergence of sprouting angiogenesis in experimental tumors

Project description:Angiogenesis-inhibitor (AI) drugs targeting vascular endothelial growth factor (VEGF) signalling to the endothelial cell (EC) are used to treat various cancers types. However, primary or secondary resistance to therapy is common. Clinical and pre-clinical studies suggest that other alternative pro-angiogenic factors are up-regulated after VEGF-pathway inhibition. Therefore, identification alternative pro-angiogenic pathway(s) is critical for the development of more effective anti-angiogenic therapy. Here we study the role of apelin as a pro-angiogenic G-protein coupled receptor (GPCR) ligand in tumor growth and angiogenesis. We applied single-cell RNA-sequencing to Mouse Lewis lung carcinoma (LLC1) or B16F10 mouse melanoma cell lines (1 X 106) implanted subcutaneously into the flanks of 12 weeks old Apln-/y or littermate control mice in combination with sunitinib or control (vehicle) treatment. We found apelin loss reduced angiogenic sprouting and tip cell marker gene expression in comparison to the sunitinib-alone treated mice and prevented EC tip cell differentiation.

Single-cell RNAseq of HA-specific CD8 T cells isolated from the hypothalamus and the spleen of mice expressing the model antigen HA in orexinergic neurons

Project description:We previously generated the Orex-HA mouse model in which orexin-producing neurons residing in the hypothalamus selectively expressed a model self-antigen, namely hemagglutinin (HA) from the H1N1 influenza virus. In this model the adoptive transfer of in vitro activated HA-specific CD8 T cells leads to the specific loss of orexinergic neurons located in the hypothalamus. To assess the phenotype and investigate the pathogenic mechanisms and the potential tissue-resident properties of autoreactive (HA-specific) CD8 T cells infiltrating the hypothalamus of Orex-HA mice , we performed a single-cell transcriptomic analysis (scRNA-seq) of HA-specific CD8+ T cells isolated from the hypothalamus and the spleen at day 30 after T cell transfer in Orex-HA mice.

Mapping the developing human immune system across organs - VDJ-seq

Project description:We profiled hematopoietic, lymphoid and peripheral fetal organs to systematically assess the heterogeneity of antigen receptors in immune cell populations across human tissues during development. Single-cell suspensions were obtained from fresh tissue. Cells were either DAPI-CD45+ or DAPI-CD45- FACS-isolated cells, or unsorted.
