Expression data from memory P14 transgenic T cells

ABSTRACT: Microarray analysis was used to compare differences and similarities in gene expression patterns between memory CD8+ T cells from mice infected with lymphocytic choriomeningitis virus (LCMV) or influenza virus. Keywords: infection response Mice containing transferred P14 CD8+ transgenic T cells were infected with LCMV or influenza and rested for 90 days. P14 cells were purified by cell sorting, as well as cells from unimmunized P14 mice as controls, and used for RNA extraction and hybridization on Affymetrix microarrays.

CXCR5+ Follicular Cytotoxic T cells Control Viral Infection in B Cell follicles

Project description:Lymphocytic Choriomeningitis Virus (LCMV) specific CD8+ T cells (P14) were transferred into congenic WT mice followed by LCMV(DOCILE) infection. CXCR5-expressing (CXCR5+) or CXCR5 non-expressing (CXCR5-) P14 were purified on day 8 after infection, and total mRNA were sequenced from these populations. mRNA of P14 from uninfected mice (Naive P14) was also sequenced. Examination of mRNA level in CXCR5 expressing P14 (CXCR5+P14) and non-expressing P14 (CXCR5-P14) from LCMV infected mice day 8 post infection. mRNA of P14 from uninfected mice (NaÃ¯ve P14) was also examined.

Expression data from LCMV-infected P14 and Akt transgenic P14 CD8 T cells

Project description:The PI3K/Akt signaling pathway impacts various aspects of CD8 T cell homeostasis, such as effect versus memory cell differentiation, during viral infection. We used microarrays to determine which downstream molecules were affected and what other signaling pathways were interconnected with the Akt pathway by constitutive activation of Akt in LCMV-infected CD8 T cells. Splenocytes from naive P14/WT or P14/Akt mice were stained with anti-CD8 and anti-Ly5.1, and CD8 T cells were sorted using a FACSAria II instrument. Purified Ly5.1+ CD8 T cells from P14/WT or P14/Akt mice were transferred into B6 mice, which were subsequently infected with LCMV Armstrong. At day 8 post infection, splenocytes were stained with anti-CD8, anti-Ly5.1, anti-KLRG1, and anti-CD127. Following staining, short-lived effector cells (SLECs) and memory precursor effector cells (MPECs) were sorted using the FACSAria II instrument; the purity of the sorted cells was >95%. A total of 5 samples were analyzed, including WT naive, WT SLEC, WT MPEC, Akt naive and Akt SLEC.

Primary and secondary CD8 T cells during acute and chronic LCMV infection

Project description:Understanding the response of memory CD8 T cells to persistent antigen re-stimulation and the role of CD4 T cell help is critical to the design of successful vaccines for chronic diseases. However, studies comparing the protective abilities and qualities of memory and naïve cells have been mostly performed in acute infections, and little is known about their roles during chronic infections. Herein, we show that memory cells dominate over naïve cells and are protective when present in large enough numbers to quickly reduce infection. In contrast, when infection is not rapidly reduced, memory cells are quickly lost, unlike naïve cells. This loss of memory cells is due to (i) an early block in cell proliferation, (ii) selective regulation by the inhibitory receptor 2B4, and (iii) increased reliance on CD4 T cell help. These findings have important implications towards the design of T cell vaccines against chronic infections and tumors. 16 samples are analyzed: 3 replicates of secondary effector CD8 P14 T cells at day 8 post-acute lymphocytic choriomeningitis virus (LCMV) infection; 4 replicates of secondary effector CD8 P14 T cells at day 8 post-chronic LCMV infection; 4 replicates of primary effector CD8 P14 T cells at day 8 post-acute LCMV infection; and 5 replicates of primary effector CD8 P14 T cells at day 8 post-chronic LCMV infection.

Expression Data from Memory P14 Tg CD8 T cells after either saline mock-infection, Pichinde Virus Infection (bystander infection) or Pichinde Virus infection with daily treatment with anti-CD122 (clone TM-b1)

Project description:Exposure to inflammatory cytokines driven by bystander cytokines can have profound effects on the function of memory CD8 T cells. Here we transferred a 1-5X10^4 of P14 TCR-tg T cells (specific for gp33-41 of LCMV) on day -1 followed by infection with 2X10^5 PFU of LCMV Armstrong ip to generate memory P14 populations. Mice were rested for >50 days before further challenge. Mice containing memory P14 populations were either mock-infected with saline, infected with 2X10^6 Pichinde Virus ip (no cross-reactivity wtih LCMV gp33-41) or infected with 2X10^6 Pichinde Virus ip together with daily injections of 200 micrograms of anti-CD122 antibody (clone TM-b1). On day 4 following indicated treatments P14s were flow sorted and RNA was extracted from 1X10^6 cells using an RNeasy kit (Qiagen). Each group had 3 biological replicates. Transcriptomes were compared by DAVID analysis (p<0.01, Fold-Change > 1.5) 3 biological replicates per group. Groups included P14 from mock-infected mice, P14 from Pichinde virus infected mice and P14 from Pichinde virus and anti-cd122 treated mice.

Expression data of ex vivo and stimulated p14 TE (day 8) and p14 TM (day 46)

Project description:The spectrum of pathogen-specific CD8+T cell functionalities, including their chemokine production profiles, remains incompletely defined. Here, we have employed microarray analyses to determine the gene expression profiles of lymphocytic choriomeningits virus- (LCMV-) specific effector (TE) and memory (TM) CD8+T cells in the established p14 chimera model; analyses of p14 TE and TM expression profiles were conducted directly ex vivo and after 3h TCR engagement using aCD3 and aCD28 antibodies (note that the present ex vivo p14 TE and TM data have previously been uploaded in the context of a related study [GSE38462] and are included here due to analyses now conducted together with stimulated p14 TE and TM data).

RNA-seq of LCMV GP33-specific CD8 TCR transgenic cells (P14) primed at the onset versus in the midst of persistent LCMV-Clone 13 viral infection

Project description:Altered CD8 T cell differentiation and functional exhaustion prevent control of chronic virus infection and cancer. Yet, how fate commitment and exhaustion are determined and dynamically modulated throughout persistent infection are unclear. We compared the activation and differentiation of LCMV GP33-specific CD8 TCR transgenic cells (P14) primed at the onset versus in the midst of established persistent LCMV-Clone 13 viral infection. LCMV GP33-specific CD8 TCR transgenic (P14) cells were injected into naïve mice immediately infected with LCMV-Cl13 (Early priming) or into mice that had been infected 21 days earlier with LCMV-Cl13 (Late Priming). Sixty hours post-priming P14 cells were sorted from mice and subjected to RNA seq. We show early primed cells very rapidly exhibit a transcriptional profile of robust activation, effector differentiation and dysfunction, while late primed cells have increased expression of genes involved in memory differentiation and maintenance.

Expression profile of miR-17-92a-MSCV-IRES-Thy1.1 transduced P14 CD8+ T cells

Project description:During acute viral infections, effector CD8+ T cells differentiate into memory precursors or short-lived terminal effectors. miR-17-92a over-expression skews CD8+ effector cells to the terminal differentiation. We used microarray to identify the genes that are differentially expressed caused by miR-17-92a over-expression. CD8+ T cells from P14 TCR transgenic mice were infected with miR-17-92a-MSCV-IRES-Thy1.1 vector and transfer to C57BL6 recipients. Chimeras were infected with LCMV Armstrong. Thy1.1+ miR-17-92a-MSCV-IRES-Thy1.1 transduced P14 cells and Thy1.1- non-transduced P14 cells were sorted by FACS. RNA was extracted from samples, labeled, and hybridized to Affymetrix microarrays.
