Cortisol (Hydrocortisone) Treatment of Activated Primary Human CD8⁺ T Cells

ABSTRACT: Peripheral blood mononuclear cells (PBMCs) were isolated by density-gradient centrifugation using Ficoll-Paque Plus. CD8⁺ T cells were purified from PBMCs by immunomagnetic negative selection and cultured for a total of 8 days. Cells were initially activated for 72 h with plate-bound anti-CD3 (1 µg/mL) and anti-CD28 (1 µg/mL). Cells were then rested/expanded for a further 72 h in fresh ImmunoCult medium supplemented with human IL-2 (100 U/mL). Finally, cells were re-stimulated with plate-bound anti-CD3 (1 µg/mL) and anti-CD28 (1 µg/mL) in the presence of cortisol (hydrocortisone; 100 nM) or vehicle control (methanol) for 48 h. Total RNA was isolated at the end of treatment for transcriptomic profiling to quantify the glucocorticoid-driven gene expression programme in activated human CD8⁺ T cells.

Genome wide glucocorticoid receptor (GR) binding sites upon cortisol treatment in human CD8 T cells

Project description:To map genome-wide chromatin occupancy of the human glucocorticoid receptor (GR; encoded by NR3C1) in primary activated human CD8⁺ T cells, ChIP–seq was performed following physiological cortisol stimulation. CD8⁺ T cells were isolated from healthy adult donors by immunomagnetic negative selection, activated in vitro with plate-bound anti-CD3 and anti-CD28, expanded in IL-2, and then re-stimulated with anti-CD3/anti-CD28 in the presence of hydrocortisone (cortisol; 100 nM) for 48 hours or vehicle control. GR-bound chromatin was immunoprecipitated and profiled by high-throughput sequencing to identify cortisol-induced GR binding sites and infer direct GR target loci in human CD8⁺ T cells.

The effect of IFNα on human CD8 T cells_with other concomitant signals

Project description:IFN alpha mediated gene expression pattern. The effect of IFN alpha on human CD8 T cells responding to antigen (signal 1) and costimulatory signals (signal 2) provided by beads coated with anti-CD3 and anti-CD28 mAbs. This analysis examined the effects of IFN alpha on human CD8 T cells responding to antigen (signal 1) and costimulatory signals (signal 2) provided by beads coated with anti-CD3 and anti-CD28 mAbs. Magnetically sorted untouched CD8+CD45R0- T cells from three different donors were unstimulated or stimulated with IFNa2b or with anti-CD3/CD28 Beads alone or along with IFNa2b or IFNa5 for 48 hours. Individual mRNA samples were analyzed using HG-U133A 2.0 array gene chips. Keywords: Gene expression analysis after different stimulation Magnetically sorted untouched CD8+CD45R0-T cells from three different donors (named A, B and C) unstimulated or stimulated with IFN alpha 2b or with anti-CD3/CD28 beads alone or along with IFN alpha 2b or IFN alpha 5 for 48 hours.

Gene expression in CD8+ T cells derived from Nrdp1+/+ and Nrdp1-/- mice

Project description:The purpose of this study was to determine which genes are differentially regulated by the E3 ligase Nrdp1 in CD8+ T cells after treatments with anti-CD3/CD28 Abs. The results demonstrate increased induction of cytotoxicity-associated genes in Nrdp1-/- mice than in Nrdp1+/+ mice after activation. Thus Nrdp1 may be involved in the regulation of TCR signaling. Naive CD8+ T cells derived spleens of Nrdp1+/+ and Nrdp1-/- mice were either untreated or treated with immobilized anti-CD3 (5 μg/ml) and soluble anti-CD28 (1 μg/ml) Abs for 4h or 8h. Equal amounts of RNA were assayed for gene expression using Affymetrix mouse 430 2.0 arrays.

Transcription profiling of human Parp-1 deficient and wild type T cells following CD3 and CD3/CD28 activation

Project description:Primary T cells were isolated from spleen of Parp-1-/- and wild-type mice by magnetic depletion of non-T cells using a MACS Pan-T Cell isolation kit, according to the manufacturer´s instruction (Mintenyi Biotec, Bergisch Gladbach, Germany). Purity was assessed by flow cytometry analysis using antibodies against CD3, CD4 and CD8 and all preparations were more than 98% pure of T cells. The cells were activated with plate-bound anti-mouse CD3 (clone 145-2C11) (5 microg/ml) in the absence or the presence of anti-mouse CD28 (clone 37.51) (5microg/ml) both from BD PharMingen (San Diego, CA) and culture for 3.5 h in RPMI 1640 medium (BioWhittaker) supplemented with 10% FCS, 2mM L-glutamine, 5x10-5 M 2-mercaptoethanol (Sigma), 2.5 microg/ml fungizone, 100 IU/ml penicillin, and 10 microg/ml streptomycin.

CD38-NAD+ Immuno-Metabolic Axis Regulates Potent Anti-Tumor T Response

Project description:Spleens from the B6 mice were isolated and single cell suspension was made. CD4 T cells were purified from the splenocytes using magnetic bead separation. Briefly, Splenocytes were incubated with biotinylated antibody cocktail consisting of antibodies (Biolegend) to CD19, B220, CD11b, CD11c, NK1.1, Gr1, CD25 CD8. After a wash step, cells were incubated with streptavidin conjugated magnetic particles (BD Biosciences). After washing, CD4 T cells were isolated by applying a magnetic field and removing the untouched cells. Purified CD4 T cells were then activated with plate-bound anti-CD3 plus anti-CD28 in presence of either Th1 or Th17 or Th1/17 polarizing condition for 3 days. Total RNA from the 3 days differentiated Th1, Th17 and Th1/17 cells was isolated using mirVana miRNA isolation Kit (Invitrogen).

For in vivo activation, naive CD8+ T cells from Tfap4â/â OT-I or control WT OT-I TCR transgenice mice were adoptively transferred to congenic host mice that were subsequently infected with Listeria mnocytogenes expression ovalbumin. Activated OT-I cells were harvested 48 hours after infection.
