Gene expression in peripheral blood Tcells from sows
Ontology highlight
ABSTRACT: Whole blood was collected from sows and peripheral blood mononuclear cells (PBMC) were isolated. CD3+CD4+, CD3+CD8+ and CD3+CD4+CD8+ were separately sorted by a cell sorter. Transcriptional profile of each T cell subset was obtained.
Project description:The secretome of y-irradiated peripheral blood mononuclear cells (PBMC) is well known for its pleiotropic effects on tissue protection and regeneration. Irradiation of PBMC lead to necroptosis of a certain amount of PBMC in a cell-sorter analysis. The aim of this study was to investiage the trancriptomic changes of PBMC and PBMC subsets (CD4, CD8, CD19, CD56, CD14) in response to y-irradiation
Project description:To identify the molecular markers of early pregnancy in pigs, we compared global gene expression profiles of the maternal peripheral blood in pregnant sows with the non-pregnant sows. Peripheral blood sample was collected at 14 days after insemination from the submandibular vein of pregnant and non-pregnant sows respectively, and total RNA was isolated, purified and sent for microarray analysis. This study identified 127 up-regulated and 56 down-regulated genes (FC >= 1.5 and P < 0.05) in peripheral blood from pregnant sows versus non-pregnant sows. Of the differently expressed genes, nine (including LPAR3, RXFP4, GALP, CBR1, CBR2, GPX6, USP18, LHB and NR5A1) were found to exert function related to early pregnancy processes. Seven differentially expressed genes (CHGB, USP18, VWF, LPAR3, NR5A1, PPARD, BIN1) were selected to perform qRT-PCR in the same RNA samples.The expression profiles of these genes detected by qRT-PCR were consistent with those by microarray, which confirmed the reliability of our microarray data.
Project description:Subpopulations of human fetal thymocyte and circulating naïve T cells were obtained through FACS sorting, including CD3-CD4+CD8- intrathymic T progenitor cells (ITTP), CD3intCD4+CD8+ "double positive" thymocytes (DP), CD3highCD4+CD8- "single positive" thymocytes (SP4), CD3+CD4+CD8-CD45RA+CD62L+ naïve T cells from cord blood (CB4+), and CD3+CD4+CD8-CD45RA+CD62L+ naïve T cells from adult blood (AB4+).

Project description:CD8 single positive T cells and CD4/CD8 double positive T cells were sorted from porcine colosrum and blood by using a cell sorter. Transcriptional profiles was compared between colostral and blood T cells.
Project description:Epigenetic therapy overcame alemtuzumab resistance in patients with relapsed T-cell prolymphocytic leukemia and induced the expression of treatment related genes. Method: patient PBMCs from Ficoll, normal patient PBMCS enriched for CD3+/CD8+ or CD3+/CD8+/CD45RA+/CCR7- were extracted in Trizol. Conclusion: Gene expression profiles were changed by epigenetic therapy, likely activating treatment response genes silenced by carcinogenesis. Total RNA from patient Peripheral Blood Mononuclear Cells (PBMC) or from normal negatively enriched CD3+/CD8+/CCR7-/CD45RA+(CD45RO-) blood
Project description:Blood immune cells transcriptome can be used as a tool to investigate molecular mechanisms or identify biomarkers of several physiological processes. Factors such as reproductive status, age, or physical and mental states resulting from social and non-social environmental aspects can influence the activation and phenotype of immune cells. Here we describe the gene expression levels in peripheral blood mononuclear cells (PBMC) of multiparous sows of various parity ranks housed during gestation in a stable social group either in a conventional environment on a slatted concrete floor (C) or in an enriched environment with deep straw litter and a bigger space allowance (E).
Project description:The RNA-sequencing to profile patient peripheral blood mononuclear cell (PBMC) samples of systemic lupus erythematosus (SLE, N=25), primary Sjögren’s syndrome (pSS, N=23), and healthy control (HD, N=24). We collected on the steady-state and 18-hours anti-CD3 culture to identify the transcriptome remodeling upon T-cell stimulation. Each patient samples were sorted for CD4+ (Th cells) and CD8+ (CTL) T lymphocytes, CD16+CD7+ cells (NK cells), and CD19+ cells (B cells).
