Raman Spectroscopy and Machine Learning Reveals Early Tumor Microenvironmental Changes Induced by Immunotherapy

Scientists demonstrated the first application of label-free Raman spectroscopy for elucidating biomolecular changes induced by anti-CTLA-4 and anti-PD-L1 immune checkpoint inhibitors in the tumor microenvironment of colorectal tumor xenografts.

Therapeutically Expanded Human Regulatory T-cells Are Super-Suppressive Due to HIF1A Induced Expression of CD73

Scientists demonstrated that expanded human Tregs switch their metabolism to aerobic glycolysis and show enhanced suppressive function through hypoxia-inducible factor 1-alpha driven acquisition of CD73 expression.

Differential Expression Profile of Gluten-Specific T Cells Identified by Single-Cell RNA-Seq

In this first single-cell RNA-seq study of tetramer-sorted T cells from untreated celiac disease patients blood, investigators found that gluten-specific T cells showed distinct transcriptomic profiles consistent with activated effector memory T cells that shared features with Th1 and follicular helper T cells.

Differential Levels of mRNAs in Normal B Lymphocytes, Monoclonal B Lymphocytosis and Chronic Lymphocytic Leukemia Cells from the Same Family Identify Susceptibility Genes

Researchers hypothesized that progressive changes in gene expression resulted in malignant transformation of B lymphocytes to family histroy of monoclonal B lymphocytosis, and subsequent alterations in gene expression occur before overt family history of chronic lymphocytic leukemia develops.

CD73-Mediated Adenosine Production by CD8 T Cell-Derived Extracellular Vesicles Constitutes an Intrinsic Mechanism of Immune Suppression

The authors showed that extracellular vesicles isolated from the synovial fluid of patients with juvenile idiopathic arthritis contribute to T cell suppression in a CD73-dependent manner.

Costimulation Molecules Differentially Regulate the ERK-Zfp831 Axis to Shape T Follicular Helper Cell Differentiation

The authors found that phorbol 12-myristate 13-acetate + ionomycin stimulation, together with interleukin-6, potently induced T follicular helper cell-like transcriptomic programs in vitro.

Prognostic Implications of Tumor-Infiltrating T Cells in Early-Stage Endometrial Cancer

The proportion of T cells and their subpopulations were associated with clinicopathological features and relapse-free survival outcomes. CD3+ CD4+ infiltrates were more abundant in the patients with higher grade or non-endometrioid histology.
