Metastatic Cancer Cells Implode on Protein Contact
By attaching a cancer-killer protein to white blood cells, researchers have demonstrated the annihilation of metastasizing cancer cells traveling throughout the bloodstream.

Angiogenic T Cells Are Decreased in Rheumatoid Arthritis Patients
Researchers analyzed the angiogenic T cell (Tang) and endothelial progenitor cell (EPC) populations in relation to disease-specific features and traditional cardiovascular risk factors. Tang (CD3+CD31+CXCR4+) and EPC (CD34+VEGFR2+CD133+) populations were quantified by flow cytometry in peripheral blood samples from 103 rheumatoid arthritis patients and 18 matched healthy controls. [Ann Rheum Dis] Abstract

TL1A Induces TCR Independent IL-6 and TNF-α Production and Growth of PLZF+ Leukocytes
Researchers investigated the role of TL1A in a pro-inflammatory setting, using human leukocytes purified from healthy donors. They showed that TL1A, together with IL-12, IL-15 and IL-18, directly induces the production of IL-6 and TNF-α from leukocytes. [PLoS One] Abstract | Press Release

Comprehensive Analysis of miRNA Expression in T-Cell Subsets of Rheumatoid Arthritis Patients Reveals Defined Signatures of Naive and Memory Regulatory T Cells
Investigators found a positive correlation between increased expression of microRNA (miR)-451 in T cells of rheumatoid arthritis patients and disease activity score, erythrocyte sedimentation rate levels and serum levels of interleukin-6. [Genes Immun] Full Article

Increased Th17/Regulatory T Cell Ratio in Chronic Liver GvHD
Scientists evaluated Th17 cells in biopsies from a cohort of 17 patients with liver chronic GVHD (cGvHD). They observed a significant increase in Th17 cells in the liver of patients with cGvHD, as demonstrated by an increase in CCR6+, CD161+ and RORγt+ T cells. [Bone Marrow Transpl] Abstract

Impact of In Vivo T-Cell Depletion on Outcome of AML Patients in First CR Given Peripheral Blood Stem Cells and Reduced-Intensity Conditioning Allo-SCT from a HLA-Identical Sibling Donor: A Report from the Acute Leukemia Working Party of the European Group for Blood and Marrow Transplantation
This study assessed the outcome of 1250 adult patients with de novo AML in first CR given PBSC from HLA-identical siblings after chemotherapy-based reduced-intensity conditioning. A total of 554 patients did not receive any form of in vivo T-cell depletion, whereas antithymocyte globulin and alemtuzumab were given in 444 and 252 patients, respectively. [Bone Marrow Transpl] Abstract

Ex-Vivo Whole Blood Secretion of Interferon (IFN)-γ and IFN-γ-Inducible Protein-10 Measured by Enzyme-Linked Immunosorbent Assay Are as Sensitive as IFN-γ Enzyme-Linked Immunospot for the Detection of Gluten-Reactive T Cells in Human Leucocyte Antigen (HLA)-DQ2·5+-Associated Celiac Disease
The authors aimed to develop whole blood assays to detect gluten-specific T cells. Blood was collected before and after gluten challenge from gluten-free diet (GFD) donors confirmed to have Celiac disease (CD), GFD donors confirmed not to have CD and donors with CD not following GFD.

Invariant Natural Killer T-Cell Neutralization Is a Possible Novel Therapy for Human Eosinophilic Esophagitis
Scientists tested the hypothesis that invariant natural killer T cells are induced in the human eosinophilic esophagitis (EoE) and is a novel possible target for the treatment of human EoE. [Clin Transl Immunol]

The Human Side of Microglia
This review takes the example of neuroimmunology research and the microglia cell type to illustrate the emerging differences between rodent and human research findings. [Trends Neurosci] Abstract

Regulation of the Anti-Tumor Immune Response by Cancer Associated Fibroblasts
The authors review recent findings on how cancer associated fibroblasts can influence the immune status of tumors through direct and indirect interaction with immune cells and other key components of the tumor microenvironment. [Semin Cancer Biol] Abstract

Agenus Announces Phase II Checkpoint Inhibitor Combination Trial with Prophage Cancer Vaccine for Melanoma
Agenus Inc. announced initiation of a randomized Phase II trial with Prophage for melanoma, and Bristol-Myers Squibb’s Yervoy® (ipilimumab) for the treatment of Stage III and IV metastatic melanoma. The combination has the potential to trigger a more effective immune response against the tumor than Yervoy alone. [Agenus Inc.] Press Release
