Comparison of gene expression profiles of Jurkat cells with or without PD-1 ligation

Project description:CD8+ T cells in chronic viral infections like HIV develop functional defects such as loss of IL-2 secretion and decreased proliferative potential that are collectively termed exhaustion1. Exhausted T cells express increased levels of multiple inhibitory receptors, such as Programmed Death 1 (PD-1). PD-1 inhibition contributes to impaired virus-specific T cell function in chronic infection because antibody-mediated blockade of its ligand, Programmed Death Ligand 1 (PD-L1) is sufficient to improve T cell function and reduce viral replication in animal models. Reversing PD-1 inhibition is therefore an attractive therapeutic target, but the cellular mechanisms by which PD-1 ligation results in T cell inhibition are not fully understood. PD-1 is thought to limit T cell activation by attenuating T cell receptor (TCR) signaling. It is not known whether PD-1 ligation also acts by upregulating genes in exhausted T cells that impair their function. Here, we analyzed gene-expression profiles from HIV-specific CD8+ T cells in patients with HIV and show that PD-1 coordinately upregulates a program of genes in exhausted CD8+ T cells from humans and mice. This program includes upregulation of basic leucine transcription factor, ATF-like (BATF), a transcription factor in the AP-1 family. Enforced expression of BATF was sufficient to impair T cell proliferation and cytokine secretion, while BATF knockdown reduced PD-1 inhibition. Silencing BATF in CD4+ and CD8+ T cells from chronic viremic patients rescued HIV-specific T cell function. Thus inhibitory receptors can cause T cell exhaustion by upregulating genes â such as BATF â that inhibit T cell function. PD-1 expressing Jurkat cells were cultured for 18 hours with beads coated with antibodies to CD3 and CD28, with our without an antibody to PD-1.

Diagnosis of Parkinson's Disease Based on Disease-Specific Autoantibody Profiles

Project description:Parkinson's Disease (PD) and Non-Demented Control (NDC) human sera were probed onto human protein microarrays in order to identify differentially expressed autoantibody biomarkers that could be used as diagnostic indicators. In the study presented here, 29 PD and 40 NDC human serum samples were probed onto human protein microarrays in order to identify differentially expressed autoantibodies. Microarray data was analyzed using several statistical significance algorithms, and autoantibodies that demonstrated significant group prevelance were selected as biomarkers of disease. Prediction classification analysis tested the diagnostic efficacy of the identified biomarkers; and differentiation of PD samples from other neurodegeneratively-diseased and non-neurodegeneratively-diseased controls (Alzheimer's disease, multiple sclerosis, and breast cancer) confirmed their specificity.

Analysis of the TCR signalosome in primary T cells

Project description:T-cell receptor (TCR) signaling is essential for the function of T cells. Here we combine mouse genetics and affinity purification coupled to quantitative mass spectrometry to monitor the composition and dynamics of the signaling complexes that assemble around 15 nodes of the TCR signaling cascade of primary CD4+ T cells. This dataset contains the experiments performed with 14 different bait proteins • Cbl • Cblb • Fyb • Inpp5d • Itk • Lck • Lcp2 • Nck1 • Nfatc2 • Plcg1 • Ptpn22 • Ptpn6 • Themis • Vav1 Each of them contains mass spectrometry results from the analysis of AP-MS experiments, based on the endogenous expression of One-Strep-tagged (OST) bait proteins in engineered mice models, and affinity purification of these proteins from primary CD4+ T cells, using Streptactin beads. Purification of OST proteins was performed at 5 different time points of stimulation of CD4+ T cells with anti-CD3 and anti-CD4 antibodies (0s; 30s; 120s; 300s; 600s). Each AP-MS purification of an OST- protein is associated with a corresponding control (purification from WT CD4+ T cells) at the same time point of stimulation. Several biological replicate experiments (time course OST series + associated WT controls) were performed for each bait. Several MS replicates were acquired for each sample. In addition, we analyzed the total proteome of CD4+ T cells isolated from each engineered mice model (14 different mice expressing an OST bait) and from WT mice, in order to calculate copy numbers of the baits and their associated proteins.

Restoring PD-1 immune checkpoint inhibitor response following IFNγ-driven adaptive resistance

Project description:Immune checkpoint inhibitors (ICIs) are a type of cancer treatment that work by targeting molecules on immune cells that can inhibit the immune system's ability to attack cancer cells. One such checkpoint molecule is PD-1, which is found on the surface of T cells (a type of immune cell) and helps to prevent them from attacking healthy cells. When PD-1 binds to its ligand (a molecule on the surface of some cells), it sends a signal to the T cell to \\"turn off\\" and not attack the cell. This mechanism is important in preventing the immune system from attacking healthy cells, but it can also be exploited by cancer cells to avoid detection and destruction by the immune system. In this study YUMM2.1 mouse tumour cells were implanted subcutaneously. The effect of IFN-γ-pre-treatment, PARP14 inhibition and PD-1 antibody treatment are reported by RNA-seq.

Mapping the SLP76 interactome in T cells lacking each of the GRB2-family adaptors reveals molecular plasticity of the TCR signaling pathway

Project description:The propagation of intracellular T cell receptor (TCR) signals involved various adapter proteins that are important molecular switches to connect proteins together. The global characterization of changes in protein-protein interactions following genetic perturbations is critical to understand the reorganization of protein networks associated with the observed phenotypes. Here, by combining genome editing techniques and AP-MS analysis we determined and quantified the molecular reorganization of the SLP76 interactome resulting from the inactivation of each of the three GRB2-family adaptors. Our data define disruption context-specific and time-dependent networks that form around SLP76 after TCR stimulation, and selectively preserved or highly affected protein complexes that regulate T cell activation.
