Gene expression analysis of Wnt+ and Wnt- effector CD8 T cells

ABSTRACT: Wnt signal transduction during an immune response is involved in the establishment of functional CD8 T cell memory P14 ConductinLacZ CD8 T cells (CD45.2) were transferred in CD45.1+.2+ recipient mice. The day after, recipients were infected with 200pfu LCMV WE. At day 8 after infection, cells from spleen and lymph nodes were harvested, magnetically enriched for CD8 T cells, loaded with the beta-galactosidase substrate (FDG) and sorted as 7AAD-negative CD45.- negative, beta-galactosidase positive versus negative cells. P14 CD8 T cells were sorted at day 8 after LCMV infection according to LacZ activity for RNA extraction and hybridization on Affymetrix microarrays.

Protection against reinfection is mediated by Ag-specific memory CD8 T cells, which display stem cell-like function. Because canonical Wnt (Wingless/Int1) signals critically regulate renewal versus differentiation of adult stem cells, we evaluated Wnt signal transduction in CD8 T cells during an immune response to acute infection with lymphocytic choriomeningitis virus. Whereas naive CD8 T cells efficiently transduced Wnt signals, at the peak of the primary response to infection only a fraction ...[more]

Expression data from memory P14 transgenic T cells

Project description: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.

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 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.

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.
