Single-cell RNA sequencing analysis of circulating leucocytes and bone marrow cells from a patient with HYOU1 Pro444His variant and heatlhy controls

ABSTRACT: In this study, we report a patient with a novel homozygous variant in HYOU1 (NM_001130991.3:c.1331C>A, p.Pro444His), who was born to related parents and presented with combined immunodeficiency, failure to thrive, and hypoglycemia. We undertook a multiomics analysis combining transcriptomics, proteomics, and single cell RNA sequencing analyses, demonstrating a drastic reduction in B cell count and hypogranulation of neutrophils in conformity with the findings of immunophenotyping. Additionally, we showed that despite the HYOU1 transcript being expressed and stable, the patient has HYOU1 deficiency at the protein level. Moreover, single cell RNA sequencing of bone marrow revealed that the B cell differentiation process is prematurely arrested at pre-pro B cell stage. The present dataset corresponds to the single-cell RNAseq performed on unsorted cells obtained from peripheral blood and bone marrow samples of the patient and healthy controls (three biological replicates for the patient and four controls)

A single recurrent dominant variant in ITPR3 leads to a syndromic immunodeficiency

Project description:Intracellular calcium levels are finely tuned through intricate actions of a number of channels and transporters, including those at key endocellular stores, e.g. endoplasmic reticulum (ER), lysosomes, and mitochondria. Along with the highly homologous genes Inositol 1,4,5-trisphosphate (IP3) receptor type 1 (ITPR1) and 2 (ITPR2), ITPR3 encodes the IP3 receptor (IP3R), a key player in intracellular calcium release in animals. Here we report the first cases of ITPR3 defects in man leading to a primarily dysimmune phenotype. In four unrelated patients of diverse ethnicity, and suffering from a complex immunodeficiency syndrome, we report the same de novo pathogenic variant - c.7570C>T; p.Arg2524Cys - in ITPR3. Clinically, recurrent severe infectious episodes of viral and bacterial origins, features of ectodermal dysplasia and that of Charcot-Marie-Tooth disease were paramount. The identified variant does not affect gene transcription, yet it was structurally predicted and biologically proven to disrupt proper protein folding and function in vivo. This eventually leads to defective Calcium flux in patient cells, dysregulation of mitochondrial function and a broad dysimmune phenotype characterized primarily by a profound CD4 T cell lymphopenia associated with quasi absence of naïve CD4 and CD8 cells, itself mirrored by an increase in cognate memory cells. The Calcium signaling defect was recapitulated ex vivo through the introduction of this single variant in Jurkat cells. Moreover, site-directed mutagenesis displayed the exquisite sensitivity of Arg2524 to any amino acid change. In conclusion, a single unique recurrent de novo variant in ITPR3 leads to a novel syndromic immunodeficiency.

Single cell CITE-seq and VDJ sequencing of epidermal and blood T cells

Project description:The aim of the experiment was to investigate the clonal relationship between CD8+ T cell subsets of donor matched blood with epidermal CD8+ T cells. Abdominal skin (n=8) was separated into dermis and epidermis, followed by epidermal skin and PBMC isolation. Single CD8+ T cells (n=6) and CD3+ T cells (n=2) were FACS sorted, processed with the 5’ 10x Genomics workflow and sequenced at NGI Sweden.

scRNA-seq study of hippocampal microglia, perivascular macrophages and perivascular fibroblasts in pre-plaque APP-KI mice

Project description:Aim of this experiment was to characterize whether SPP1 released from the hippocampal perivascular space could imprint microglia transcriptional states. We performed scRNA-seq analysis on sorted CD140a+ perivascular fibroblast (PVF), CD45highCD11intCD206+ perivascular macrophage (PVM) and CD45intCD11intCX3CR1high microglial cell from dissected hippocampi of 6-month old wild type vs SPP1KO/KO vs AppNL-F mice vs AppNL-FxSpp1KO/KO mice. Cells were isolated from dissected hippocampi as previously described (Sala Frigerio et al.,2019).

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 RNA-seq from Prostate Cancer Patient Derived Xenografts and LNCaP Cells

Project description:Comprehensive molecular cancer studies have extensively characterized most primary and some metastatic tumor types over the last decade. In prostate cancer, the most common tumor type in men, genomic studies have been most notably conducted for primary and metastatic tumors that had progressed under androgen deprivation therapies (ADT) to castration-resistant disease (CRPC). More recent studies have also looked at genetic alterations in a smaller number of prostate cancers frequently associated with neuroendocrine trans-differentiation. For this tumor type, it’s becoming clear that the complexity of genomic alterations does not allow an accurate assessment of the transformed phenotype. To overcome these hurdles, we show in patient-derived xenograft models how disease progression emerges at single-cell resolution and how pharmacologic perturbation can revert this process. Given this approach, we were able to investigate disease progression and androgen independence at single cell level: in our xenograft models, we show how tumor cell subpopulation progress along the trajectory from androgen-sensitive to insensitive disease.

CITE-seq of human blood CD8+ T cells

Project description:The purpose of the experiment was to investigate the differentiation state gradient among antigen-experienced CD8+ T cells in healthy human blood. This was a sub-goal within a larger experiment, which aimed to investigate the clonal relationship between CD8+ T cells in blood and skin of matched donors. The blood T cells were sorted as CD8+ T cells (n=4) or CD3+ T cells (n=2), processed according to the 5´prime 10x genomic workflow, and sequenced at NGI Sweden.

Single cell expression profiling of murine subventricular zone in adult brain three days after focal celebral ischemia

Project description:Ischemic stroke is a serious medical condition that leads to the onset of neurological symptoms such as loss of motor and cognitive functions. Focal cerebral ischemia (FCI) occurs due to the interrupted blood supply to the site of injury, resulting in the demise of brain cells. The subventricular zone (SVZ) is a source of stem and progenitor cells (NS/PCs), which proliferate and differentiate in multiple cell types in order to substitute the injured tissue. We isolated cells from the SVZ and the adjacent striatum three days after middle cerebral artery occlusion (MCAO) in order to map cellular changes and NS/PCs plasticity in adult brain upon injury. Expression profiling of the isolated tissue at the single cell level enables the identification of cell population subtypes in the region and their characteristic gene expression.
