MetabolomicsUltra-High Mass Resolving Power, Mass Accuracy, and Dynamic Range MALDI Mass Spectrometry Imaging by 21-T FT-ICR MS

Detailed characterization of complex biological surfaces by matrix-assisted laser desorption/ionization (MALDI) mass spectrometry imaging (MSI) requires instrumentation that is capable of high mass resolving power, mass accuracy and dynamic range. Fourier transform ion cyclotron resonance mass sp...

TranscriptomicsRNA-seq of T cells form house dust mite mouse model of bronchoalveolar lavage (BAL), medLN and lung tissues
This dataset profiles T cells recovered from the airway lumen (bronchoalveolar lavage, BAL), medLN and lung tissues of mice exposed to house dust mite (HDM) allergen, a model of allergic airway inflammation. The aim of this experiment was to capture, at single-cell resolution, both the transcription...

TranscriptomicsContinuous requirement for the T cell receptor for regulatory T cell function
Foxp3+ regulatory T cells (Treg cells) maintain immunological tolerance and their deficiency results in fatal multi-organ autoimmunity. Although heightened T cell receptor (TCR) signaling is critical for the differentiation of Treg cells, the role of TCR signaling in Treg cell function remains larg...

TranscriptomicsTranscription profiling of human CD4+ memory T cells reveals they are preferential targets for bystander activation and apoptosis
There is much evidence that T cells may be activated via mechanisms which act independently of direct TCR ligation. Despite this, the question of whether such forms of ‘bystander’ T cell activation occur during immune responses is hotly debated. To address some outstanding questions, we set up ...

TranscriptomicsTranscription profiling of human CD8 naive (TN), central memory (TCM), effector memory (TEM), and effector memory RA (TEMRA) T cells
Memory T cells are heterogeneous in terms of their phenotype and functional properties. We investigated the molecular profiles of human CD8 naïve (TN), central memory (TCM), effector memory (TEM), and effector memory RA (TEMRA) T cells using gene expression microarrays and phospho-protein-specific i...

Comparing Vg9Vd2 T cells with CD8 ab T cells
To compare the responses of resting and activated human Vg9Vd2 T cells (mainly CD4-CD8-) to those of conventional CD8+ ab T cells, we used Hver2.1.1 microarrays containing ~15,000 cDNAs. CD8 T cells were chosen as the conventional counterpart of huma...

TranscriptomicsSystematic RNA-seq analysis of the early events of CD4+ T cell activation
RNA-seq was used to look at the transcriptome changes and the early events of T cell receptor stimulation in CD4+ T cells CD4+ T cells were stimulated with immobilised anti-CD3/CD28 antibodies for 4 hours and RNA was extracted and subjected to RNA-seq analysis.

ProteomicsMultiomic profiling of chronically activated CD4+ T cells identifies drivers of exhaustion and metabolic reprogramming
T-cell exhaustion occurs when T cells are chronically activated, usually in the context of cancer or chronic infection. Exhausted T cells lose effector functions, upregulate inhibitory receptors, and lose proliferation ability. Understanding the mechanisms of T-cell exhaustion is important as it has...

TranscriptomicsTranscriptomic profiling of antigen-specific T cells at the single-cell level after clearance of hepatitis C virus
We used scRNA-seq data generated using Smart-seq2 to reconstruct the native TCR from Ag-specific T cells and then to link these with the gene expression profile of individual cells. antigen specific CD8 T cells were obtained from a subject who had previously cleared hepatitis C virus (HCV) infection...

ProteomicsBlocking ERK activity has a selective but critical impact on activating T cells
The mitogen activated kinases ERK1/2 are activated by antigen receptor engagement and control T cell differentiation. We have used mass spectrometry to explore how ERK1/2 control antigen receptor driven cell growth and proteome restructuring in CD8 T cells. Quantitative analysis of >8000 proteins pr...
