Identification of GP33-specific CD8 T cell clones responding to chronic infection with LCMV-Clone13

ABSTRACT: T cells specific for a certain antigen are a heterogeneous population characterized by cells expressing different T Cell Receptors (TCRs). As the TCR determines the avidity of a T cell clone for its cognate antigen, this feature has also a significant impact on the fate of such clone during antigenic challenge. In the context of chronic viral infection, T cells specific for the chronic virus differentiate into exhausted cells with limited functionality. We find that, in the process of exhaustion following infection with LCMV-Clone13, certain clones of CD8 T cells specific for the LCMV immunodominant epitope GP33 are enriched compared to others.

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.

Pd-1 High and Intermediate CD8+ T cells

Project description:During acute viral infections, naïve CD8+ T cells differentiate into effector CD8+ T cells and, after viral control, into memory CD8+ T cells. Memory CD8+ T cells are highly functional, proliferate rapidly upon reinfection and persist long-term without antigen. In contrast, during chronic infections, CD8+ T cells become “exhausted” and have poor effector function, express multiple inhibitory receptors, possess low proliferative capacity, and cannot persist without antigen. Exhuasted CD8+ T cells can be further segregated by their expression of the inhibitory cell surface receptor PD-1. We performed transcriptional profiling on both PD-1 High and PD-1 Intermediate H2-Db GP33-specific CD8+ T cells. H2-Db GP33-specific CD8+ T cells were sorted from C57BL/6 mice 30 days p.i. with LCMV clone 13. These cells were then segregated by their expression of the inhibitory cell surface receptor PD-1 into PD-1 High and PD-1 Intermediate subpopulations. We performed transcriptional profiling on these subpopulations.

Longitudinal expression data from CD8+ T cells responding to LCMV-Armstrong or LCMV-Clone 13

Project description:During acute viral infections, naïve CD8+ T cells differentiate into effector CD8+ T cells and, after viral control, into memory CD8+ T cells. Memory CD8+ T cells are highly functional, proliferate rapidly upon reinfection and persist long-term without antigen. In contrast, during chronic infections, CD8+ T cells become “exhausted” and have poor effector function, express multiple inhibitory receptors, possess low proliferative capacity, and cannot persist without antigen. To compare the development of functional memory T cells with poorly functional exhausted T cells, we generated longitudinal transcriptional profiles for each. Naive CD44Lo CD8+ T cells were isolated and sorted from uninfected C57BL/6 mice and H2-Db GP33-specific CD8+ T cells were sorted using MHC-I tetramers at d6, 8, 15, and 30 p.i. with either LCMV Arm or LCMV clone 13. RNA from these CD8+ T cells was processed, amplified, labeled, and hybridized to Affymetrix GeneChip MoGene 1.0 st microarrays

Single-cell immune repertoire sequencing of B and T cells following infection and autoimmunity

Project description:Single-cell immune repertoire sequencing (gene expression and immune receptor repertoire) was performed under various contexts. This includes CD4 T follicular cells (sorted by surface expression of PD1+ CXCR5+ CD4+) following high dose LCMV clone 13 infection on days 10, 25, and 50 and low dose clone 13 infection on day 10 post infection. We additionally profiled virus-specific CD8 T cells that are specific to either GP33 or NP396. Gp33-specific CD8 T cells were sorted 15 months post infection with either low dose clone 13 LCMV, MCMV-ie2-gp33 or MCMV-m45-gp33. NP396-specific CD8 T cells were isolated either 10 days post challenge or 25 days post challenge using the viral model of dejavu (https://pubmed.ncbi.nlm.nih.gov/16604192/). B and T cells were isolated 14 days post induction of Experimental autoimmune encephalomyelitis (EAE).

Early Transient IFN-γ Production-dependent and Independent Mechanisms Underlie the Cross-protectivity of Lung-Resident Memory CD8 T Cells against Respiratory Virus Challenge

Project description:Transcriptome profiling of lung tissues and lung CD8+ TRM during early phase of infection to investigate the mechanism of lung TRM cells during antigen re-exposure within 48hours. After P14 T cell transfer, PR8 infection would not induce P14 TRM cells, while PR8-gp33 would. Comparing the gene expression of lung tissues after LCMV Armstrong challenge at day 30 after PR8 or PR8-gp33 infection would help us understand the function of lung CD8+ TRM cells. Sorted TRM cells from mice challenged with LCMV Armstrong at day 30 after PR8-gp33 infection would reveal the activation mechanism of TRM cells.

Project description:miRNA profiling of Db-GP33-41 specific murine CD8 T cells following infection with LCMV Armstrong Various in-vivo subsets of antigen-specific CD8 T cells were FACS sorted and analyzed for miRNA expression profiling. Samples were purified from either uninfected animals or after days 4.5, 9 and >60 post infection with LCMV Armstrong.

Whole mouse genome analysis of LCMV-specific CD4 and CD8 T cells throughout acute and chronic LCMV infection.

Project description:CD4 and CD8 T cells display functional defects during chronic infection such as loss of certain cytokines. Recent studies have suggested that CD4 T cells may actually gain other functions, however. Here, we analyzed gene expression profiles from LCMV-specific CD4 and CD8 T cells throughout the response to either acute LCMV or chronic LCMV infection. This alllowed us to identify CD4-specific changes during chronic infection compared to acute infection but also revealed shared core regulators between CD4 and CD8 T cells. LCMV-specific CD4 and CD8 T cells were isolated 6, 8, 15 and 30 days post infection with LCMV Armstrong or LCMV clone 13. Naïve CD4 and CD8 T cells were also isolated from naïve mice as comparisons. Four replicates of each sample were hybridized. The only exception is LCMV-specific CD4 T cells isolated 6 days post infection with LCMV-Arm where only three replicates were hybridized.

Paired scRNA-seq and scTCR-seq of GP33-specific CD8 T cells in chronic LCMV infection

Project description:Chronic viral infection results in CD8 T cell exhaustion. Here, we use paired single-cell RNA sequencing (scRNA-seq) and single-cell T cell receptor sequencing (scTCR-seq) to investigate CD8 T cell phenotypic and clonal heterogeneity in multiple mice during the late stage of LCMV Clone 13 infection.

Single-cell RNA-sequencing of virus-specific GP33+CD8+ T cells from day 33 post-LCMV Cl13 infection

Project description:CD4+ T cells play a critical role in sustaining the effector function of CD8+ T cells during chronic viral infection. When CD4+ T cell “help” is absent, CD8+ T cells enter a dysfunctional state, losing their capacity for viral control. However, when CD4+ T cell help is present, a heterogenous population of virus-specific CD8+ T cells are present. Here, we applied scRNA-seq to distinguish CD8+ T cell heterogeneity during LCMV Clone 13 infection.
