MetabolomicsExtracellular-acidosis restricts one-carbon metabolism and preserves T cell stemness
The accumulation of acidic metabolic waste products within the tumor microenvironment profoundly inhibits effector functions of tumor-infiltrating lymphocytes (TILs). However, it is unclear whether extracellular-acidosis impacts T cell metabolic fitness and differentiation status. Here, we surprisin...

MetabolomicsThe telomere-to-telomere (T2T) genome of Peucedanum praeruptorum Dunn provides insights into the genome evolution and coumarin biosynthesis

BACKGROUND: Traditional Chinese medicine has used Peucedanum praeruptorum Dunn (Apiaceae) for a long time. Various coumarins, including the significant root constituents Praeruptorin (A-E), are the active constituents of the dried roots of P. praeruptorum. Previous trans...

MetabolomicsAssessing the potentiality of sputtered gold nanolayers in mass spectrometry imaging for metabolomics applications (Liver MALDI-MSI assay)

Mass spectrometry imaging (MSI) is a molecular imaging technique that maps the distribution of molecules in biological tissues with high spatial resolution. The most widely used MSI modality is matrix-assisted laser desorption/ionization (MALDI), but some organic matrices used in classical MALDI ...

MetabolomicsAssessing the potential of sputtered gold nanolayers in mass spectrometry imaging for metabolomics applications (Brain MALDI-MSI assay)

Mass spectrometry imaging (MSI) is a molecular imaging technique that maps the distribution of molecules in biological tissues with high spatial resolution. The most widely used MSI modality is matrix-assisted laser desorption/ionization (MALDI), mainly due to the large variety of analyte classes...

TranscriptomicsDNA methylation adds prognostic value to minimal residual disease status in pediatric T-cell acute lymphoblastic leukemia
Background: Despite increased knowledge about genetic aberrations in pediatric T-cell acute lymphoblastic leukemia (T-ALL), no clinically feasible treatment-stratifying marker exists at diagnosis. Instead patients are enrolled in intensive induction therapies with substantial side effects. In modern...

ProteomicsTranslational repression of pre-formed cytokine mRNA prevents chronic activation of memory T cells
Memory T cells are critical to protect us from recurring infections. Their instantaneous reactivity to pathogens is empowered by persistent expression of cytokine mRNA. How aberrant protein production of this pre-formed mRNA is prevented in the absence of infection, however, remains unresolved. We s...

ProteomicsPhosphoproteomic analysis of T cell receptor stimulation-induced changes in human primary CD4+CD25- T cells in the absence or presence of regulatory T cells.
Regulatory T cells (Tregs) suppress other immune cells and are indispensable for human health, yet the molecular mechanisms of suppression remain incompletely understood. Tregs can suppress proliferation and cytokine production of CD4+CD25- conventional T cells (Tcons). We previously demonstrated th...

ProteomicsActivated neutrophils exert myeloid-derived suppressor cell activity, damaging T cells beyond repair
Myeloid-derived suppressor cells (MDSCs) have the capacity to suppress T cell-mediated immune responses, and impact clinical outcome of cancer, infections and transplantation settings. Although MDSCs were initially described as bone-marrow-derived immature myeloid cells (either monocytic [m-MDSC] or...

ProteomicsA metabolism-epigenome axis controls early events in CD4+ T cell activation
Upon antigen-specific T Cell Receptor (TCR) engagement, human CD4+ T cells proliferate and differentiate, a process associated with rapid transcriptional changes and metabolic reprogramming utilizing aerobic glycolysis together with maintenance of oxidative phosphorylation1,2. However, the role of g...

TranscriptomicsGold induction of C. metallidurans CH34
Whole-genome expression microarray experiments were conducted to assess the response of C. metallidurans CH34 to aqueous Au(III)-chloride and identify possible biochemical pathways for Au detoxification. Four microarray experiments were conducted to assess gold response at low, medium and high Au(II...
