Building Immunity: Scientists Recreate a T-Cell Receptor Signaling Pathway
By successfully re-creating a T-cell receptor signaling pathway independent of the cell itself, scientists gained novel insights into how protein signaling works in a complex cellular process. [Press release from the Whitman Center of the Marine Biological Laboratory discussing online prepublication in Science]

PUBLICATIONS (Ranked by impact factor of the journal)
Dissecting the Multicellular Ecosystem of Metastatic Melanoma by Single-Cell RNA-Seq
Single-cell analyses suggested distinct tumor microenvironmental patterns, including cell-to-cell interactions. Analysis of tumor-infiltrating T cells revealed exhaustion programs, their connection to T cell activation and clonal expansion, and their variability across patients. [Science] Abstract

Tumoral Immune Cell Exploitation in Colorectal Cancer Metastases Can Be Targeted Effectively by Anti-CCR5 Therapy in Cancer Patients
Analyzing the invasive margin of human colorectal cancer liver metastases, investigators identified a mechanism of immune cell exploitation by tumor cells. While two distinct subsets of myeloid cells induce an influx of T cells into the invasive margin via CXCL9/CXCL10, CCL5 is produced by these T cells and stimulates pro-tumoral effects via CCR5. [Cancer Cell] Abstract | Graphical Abstract

Targeting Non-Proteolytic Protein Ubiquitination for the Treatment of Diffuse Large B Cell Lymphoma
Researchers showed that the CARD11-MALT1-BCL10 complex includes the E3 ubiquitin ligases cIAP1 and cIAP2, which are essential mediators of B cell receptor-dependent NF-κB activity in the activated B cell-like subtype of diffuse large B cell lymphoma. [Cancer Cell] Abstract

Zinc-Induced Polymerization of Killer-Cell Ig-Like Receptor into Filaments Promotes Its Inhibitory Function at Cytotoxic Immunological Synapses
The inhibitory function of killer cell immunoglobulin-like receptors (KIR) that bind HLA-C and block activation of human natural killer cells is dependent on zinc. The authors report that zinc induced the assembly of soluble KIR into filamentous polymers, as detected by electron microscopy, which depolymerized after zinc chelation. [Mol Cell] Abstract | Graphical Abstract

OX40+ Regulatory T Cells in Cutaneous Squamous Cell Carcinoma Suppress Effector T Cell Responses and Associate with Metastatic Potential
To investigate reasons for failure of T cells to mount a protective response in cutaneous squamous cell carcinoma, scientists focused on regulatory T cells as this suppressive population is well represented among the infiltrating lymphocytes. [Clin Cancer Res] Abstract | Full Article

CD4+ and CD8+ TCRβ Repertoires Possess Different Potentials to Generate Extraordinarily High-Avidity T Cells
Researchers showed that the transduction of SIG35α, the public chain-centric HLA-A*02:01(A2)/MART127–35 TCRα hemichain, conferred A2/MART127–35 reactivity to a substantial subset of both CD8+ and CD4+ T cells regardless of their HLA–A2 positivity. [Sci Rep] Full Article

Reduced Number of Transitional and Naive B Cells in Addition to Decreased BAFF Levels in Response to the T Cell Independent Immunogen Pneumovax®23
Researchers analyzed the effect of a T cell independent antigen on the B cell compartment through immunization of healthy individuals with the pneumococcal polysaccharide-based vaccine Pneumovax®23, and subsequent characterization of B cell subpopulations. [PLoS One] Full Article

Differential Effects of the Two Amino Acid Sensing Systems, the GCN2 Kinase and the mTOR Complex 1, on Primary Human Alloreactive CD4+ T-Cells
The effects of general control nonderepressible 2 (GCN2) kinase activation or mammalian target of rapamycin (mTOR) inhibition on human alloreactive CD4+ T-cells were evaluated. The mixed lymphocyte reaction, as a model of alloreactivity, the GCN2 kinase activator, tryptophan, and the mTOR complex 1 inhibitor, rapamycin, were used. [Int J Mol Med] Abstract

A Multi-Laboratory Comparison of Blood Dendritic Cell Populations
The authors validated a backbone of monoclonal antibodies (mAbs) to delineate monocyte and dendritic cell (DC) populations from peripheral blood. The mAb backbone allowed identification of monocyte and DC subsets using fluorochromes that were compatible with most ‘off the shelf’ or routine flow cytometers. [Clin Transl Immunol] Full Article

Liver Immunology and Its Role in Inflammation and Homeostasis
The authors explore the changing perception of inflammation and inflammatory mediators in normal liver homeostasis and propose targeting of liver-specific immune regulation pathways as a therapeutic approach to treat liver disease. [Cell Mol Immunol] Full Article

Synthetic Glycolipid Activators of Natural Killer T Cells as Immunotherapeutic Agents
Investigators discuss the design of synthetic glycolipid activators for invariant natural killer T (iNKT) cells, their impact on adaptive immune responses and their use to modulate iNKT cell responses to improve immunity against infections and cancer. [Clin Transl Immunol] Full Article
