Project description:Genome wide DNA methylation profiling of IL-7Ra high and low EM CD8+ T cells. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,578 CpGs. Samples included 2 IL-7Ra high EM CD8+ T cells and 2 IL-7Ra high EM CD8+ T cells. Bisulphite converted DNA from the 4 samples were hybridised to the Illumina Infinium 27k Human Methylation Beadchip v1.2

Project description:It is known that human IL-7R low and high EM CD8+ T cells have a difference in the expression of some co-stimulatory, effector and cytotoxic molecules. However, their global gene expression profiles have not been characterized. We thus analyzed global gene expression by IL-7R low and high EM CD8+ T cells in healthy human peripheral blood.

Project description:We found a unique subset of effector memory (EM) CD8+ T cells that expressed high levels of IL-6 receptor in human peripheral blood. These cells which also expressed high levels of IL-7Ra (referred to as IL-6R high IL-7Rahigh cells) had the a distinct gene expression profile and cellular characteristics compared to other EM CD8+ T cells. IL-6R high IL-7Ra high cells were early differentiated EM CD8+ T cells with decreased expression of T-bet, KLRG1, perforin and granzyme B. These cells had increased cell proliferation likely secondary to enhanced IL-2 production and high affinity IL-2R expression. IL-6R high IL-7Ra high EM CD8+ T cells exclusively produced high levels of IL-2, IL-5, IL-9 and IL-13 although IFN-r was produced by this cell subset and other EM CD8+ T cells. Of interest, IL-6R high IL-7Ra high EM CD8+ T cells expanded in the peripheral blood of patients with chronic obstructive pulmonary disease (COPD) and asthma where CD8+ T cells, IL-13 and IFN-r are suggested to be involved in the pathogenesis. Being the early-differentiated EM CD8+ T cells with a potent capacity to proliferate, survive and generate multiple cytokines, IL-6R high IL-7Ra high EM CD8+ T cells may serve as a primary reservoir for effector CD8+ T cells which potently expand and produce cytokines upon immune stimulation. Duplicate experiments were performed for each condition. In each condition, we independently prepared total RNA using the RNeasy mini kit (Qiagen) and assessed RNA integrity using Bioanalyzer 2100 (Agilent)- RINs were close to 10 for all samples. RNA was then amplified and hybridized to the Illumina HumanHT-12 v4.0 BeadChip, according to Illumina standard protocols.

Project description:FACS-purified human effector memory (EM) CD8+ T cells were analyzed for single cell gene expression profile using single cell RNA-seq. The relationship of IL-7 receptor alpha expression with other molecules was determined at the single cell level. The results showed heterogeneity in human EM CD8+ T cells as defined by IL-7Ra expression that has distinct but organized relationships with a set of molecules, including effector molecules, chemokine receptors, and transcription factors.

Project description:The goal of an effective AIDS vaccine is to generate immunity that will prevent HIV-1 acquisition. Despite limited progress towards this goal, renewed optimism has followed the recent success of the RV144 vaccine trial in Thailand. However, the lack of complete protection in this trial suggests that breakthroughs, where infection occurs despite adequate vaccination, will be a reality for many vaccine candidates. We previously reported that neutralizing antibodies elicited by DNA prime/rAd5 boost vaccination with SIVmac239 Gag/Pol and Env provided protection against pathogenic SIVsmE660 acquisition after repeated mucosal challenge. Here, we report that SIV-specific CD8+ T cells elicited by that vaccine lowered both peak and set-point viral loads in macaques that became infected despite vaccination. These SIV-specific CD8+ T cells showed strong virus inhibitory activity (VIA) and displayed an effector memory (EM) phenotype. VIA correlated with high levels of CD107a mobilization and perforin expression in SIV-specific CD8+ T cells. Remarkably, both the frequency and the number of Gag CM9-specific public clonotypes were strongly correlated with VIA mediated by EM CD8+ T cells. The ability to elicit such virus-specific EM CD8+ T cells might contribute substantially to an efficacious HIV/AIDS vaccine, even after breakthrough infection. Gag CM9-specific EM CD8+ T cells (CD28 low CD95 high tetramer+) from SIV-negative macaques at 12 wks post-DNA/rAd5 immunization were sorted by flow cytometry for microarray studies. RNA samples from strong VIA animals with (n=3) or without (n=6) CM9 peptide stimulation, along with CM9 peptide stimulated samples from weak VIA animals (n=2) were prepared using the Illumina beads station assay and hybridized to the Illumina HumanHT-12 version 4 Expression BeadChip.
