ABSTRACT: Comparison of the transcriptome of naive (CD45RA+ CD27+) and differentiated (CD27-CD28-) CD4+ lymphocytes from newborns with congenital human cytomegalovirus infection (cord blood samples) and pregnant women diagnosed with primary CMV infection. Naive cells from HCMV uninfected newborns were used as a control.

Single-cell RNAseq of phenotypically defined human B cell subsets

Project description:Separation of B cells has been historically important in discovering their functional relevance, particularly in relation to infection, immune disorders and vaccination. Traditional use of phenotypic markers often poses problems in distinguishing heterogeneous populations such as the Double Negative (DN, CD19+CD27-IgD-) cells. B cells represent a small subset of PBMCs; this represents challenges to use bottom-up approaches such as single-cell transcriptomics in defining B cell subpopulations. In this study we therefore used the 10X single-cell RNAseq platform on B cell populations already defined by FACS sorting (Transitional, CD19+CD27-IgD+CD10+; Naïve, CD19+CD27-IgD+CD10-; Classical Memory, CD19+CD27+IgD-; IgM Memory, CD19+CD27+IgD+; and DN). These data match known phenotypes to transcriptionally defined B cell subpopulations, and provide a reference atlas for researchers interested in better defining B cell subsets in their data.

Human lung CD8+ T cells compared with paired non-naive peripheral blood CD8+ T cells

Project description:It is unknown whether human lung T cells recirculate or belong to a distinct tissue-specific population. This issue is important for understanding their role in protection against viral infection and their contribution to pathophysiology of lung diseases such as chronic obstructive pulmonary disease. By comparing transcriptional profiles of blood and lung CD8+ T cells, we aimed to reveal specific traits of lung CD8+ T cells. A total of 12 samples was analyzed: 10 patient samples (including 1 technical replicate) and 2 reference samples (including 1 technical replicate). Per patient (in total 3 patients), 3 paired samples were analyzed. These samples were non-naive peripheral blood CD8+ T cells (CD45R0+CD3+CD8+ T cells), memory-type lung CD8+ T cells (CD45R0+CD27+CD3+CD8+ T cells) and effector-type lung CD8+ T cells (CD45R0+CD27-CD3+CD8+ T cells). The reference population consisted of a mix of naive peripheral blood CD8+ T cells from 5 healthy donors.

Human splenic marginal zone precursors (MZP) differentiation into marginal zone B cells (MZB)through a Notch2 signalling pathway

Project description:RNA microarray profiling analysis was performed on different ex-vivo human splenic B cell subsets (M-^SNaM-oveM-^T, marginal zone precursors or M-^SMZPM-^T, marginal zone B cells orM-^T MZBM-^T, M-^SMTG+CD45+M-^T cells) and on M-^Sp27M-^T cells, corresponding to the fraction of MZP cells that differentiated into CD27-expressing cells after culture on OP9-hDLL1 cells cultured with OP9-hDLL1 cells that differentiated into CD27-expressing cells

Transcription profiling of mouse natural killer (NK) cell subsets defined by CD27 and CD11b expression

Project description:Previous reports have defined three subsets of mouse NK cells on the basis of the expression of CD27 and CD11b. The developmental relationship between these subsets was unclear. To address this issue, we evaluated the overall proximity between mouse NK cell subsets defined by CD27 and CD11b expression using pangenomic gene expression profiling. The results suggest that CD27+CD11b-, CD27+CD11b+ and CD27-CD11b+ correspond to three different intermediates stages of NK cell development. Experiment Overall Design: Spleen cells from RAG-/- mice have been isolated and stained with anti-NK1.1, anti CD27 and anti CD11b antibodies. NK1.1+ cells were sorted into CD27+ CD11b-, CD27+ CD11b+ and CD27- CD11b+ subsets by flow cytometry. There are two independent replicates for each sample. Total RNA was extracted with the RNeasy microkit (Qiagen) and gene expression profiles were performed according to manufacturer instructions (Affymetrix mouse 430 2.0).

Microarray analysis of IgA-expressing and IgG-expressing B cell subpopulations.

Project description:Circulating antibody secreting cells are present in peripheral blood of healthy individuals reflecting continued activity of the humoral immune system. Antibody secreting cells typically express CD27. We describe and characterize a small population of antibody secreting class switched CD19+CD43+ B cells that lack expression of CD27 in peripheral blood of healthy subjects. Class switched CD27-CD43+ B cells possess characteristics of conventional plasmablasts as they spontaneously secrete antibodies, are morphological similar to antibody secreting cells, show downregulation of B cell differentiation markers. In order to further characterize the cells in comparison to other B cell subtypes we performed gene expression studies. RNA was isolated from sort-purified IgA-expressing and IgG-expressing B cell subpopulations [CD27+CD43-, CD27+CD43+, CD27-CD43-, CD27-CD43+] obtained from 3 healthy adults, and microarray analysis was performed. Data from IgA-expressing B cell populations and from IgG-expressing B cell populations were normalized (separately).

Single-cell RNA and BCR sequencing of naive B cells cultured in IgG class-switching polarising conditions

Project description:Naive B cells (CD27-IgD+) were obtained from 3 healthy controls and cultured in vitro under anti-IgM, CD40L and IFN-gamma to polarise class-switching towards IgG isotypes. Single-cell RNA and BCR sequencing libraries were prepared at Day 0 (before addition of stimuli), Day 3 and Day 6 of the cell culture time-course. This is intended as a dataset to validate a new computational method sciCSR in enumerating productive and sterile immunoglobulin transcripts as indicators of B cell class switching and maturation dynamics.

RNA-seq expression profiling of humain MAIT cells in blood and liver as compared to mainstream TCD4+ and TCD8+ cells.

Project description:At variance with what is observed in mice, no distinct MAIT1 or MAIT17 subsets exist in human blood, as all MAIT cells express a variety of transcription factors such as Rorgt, Tbet, Eomes and Helios. However, they are also found in tissues in which they have specific effector functions. To determine these tissue programs, we analyzed the transcription pattern of MAIT cells as compared to mainstream memory (CD45RA-CD27+) CD4+ and CD8+ T cells from human blood and liver. The paired samples of blood and liver cells were obtained from patients operated for metastatic uveal melanoma (liver samples from a “healthy” liver fragment), and from the blood of healthy controls.

Runx3 function in splenic NK cells activated in vivo by IL-15.

Project description:NK cells are innate immune cells that recognize and kill foreign, virally-infected and tumor cells without the need for prior immunization. NK expansion following viral infection is IL-2 or IL-15-dependent. To identify Runx3 regulated genes, NK cells were isolated from spleen of IL15/Ra injected WT and Runx3-/- mice and sorted to obtain 3 subpopulations of immature (CD27) and mature (DP and CD11c) NK cells.
