TOP STORY
Every Step You Take: STING Pathway Key to Tumor Immunity
A recently discovered protein complex known as STING plays a crucial role in detecting the presence of tumor cells and promoting an aggressive anti-tumor response by the body’s innate immune system. [Press release from The University of Chicago Medical Center discussing publication in Immunity]

PUBLICATIONS (Ranked by impact factor of the journal)
STING-Dependent Cytosolic DNA Sensing Promotes Radiation-Induced Type I Interferon-Dependent Antitumor Immunity in Immunogenic Tumors
Scientists demonstrate that adaptor protein STING, but not MyD88, is required for type I interferon (IFN)-dependent antitumor effects of radiation. STING was essential for radiation-induced adaptive immune responses, which relied on type I IFN signaling on dendritic cells. [Immunity] Full Article | Press Release

The Angiogenic Factor PlGF Mediates a Neuroimmune Interaction in the Spleen to Allow the Onset of Hypertension
Researchers show a splenic role for placental growth factor (PlGF), which accounts for the onset of hypertension, through immune system modulation. PlGF repressed the expression of the protein Timp3 (tissue inhibitor of metalloproteinases 3), which allowed costimulation of T cells and their deployment toward classical organs involved in hypertension. [Immunity] Abstract | Graphical Abstract | Editorial

CXCR4 and a Cell-Extrinsic Mechanism Control Immature B Lymphocyte Egress from Bone Marrow
Investigators used two-photon intravital microscopy to show that immature B cell retention within bone marrow (BM) was strictly dependent on amoeboid motility mediated by CXCR4 and CXCL12 and by α4β1 integrin-mediated adhesion to VCAM-1. Immature B cell egress from BM was dependent on a twofold CXCR4 down-regulation that was antagonized by antigen-induced BCR signaling. [J Exp Med] Abstract | Editorial

Optimal T-Cell Receptor Affinity for Inducing Autoimmunity
Three transgenic mouse strains expressing antigens of variable affinity for the OVA transgenic-I T-cell receptor were generated to address how TCR affinity affects the efficiency of negative selection, the ability to prime an autoimmune response, and the elimination of the relevant target cell. Mice expressing antigens with an affinity just above the negative selection threshold exhibited the highest risk of developing experimental autoimmune diabetes. [Proc Natl Acad Sci USA] Abstract

Uncoupling Malt1 Threshold Function from Paracaspase Activity Results in Destructive Autoimmune Inflammation
Researchers demonstrate that targeted Malt1-paracaspase inactivation induces a lethal inflammatory syndrome with lymphocyte-dependent neurodegeneration in vivo. In addition to NF-κB inhibitors, Malt1 cleaves an entire set of mRNA stability regulators and paracaspase inactivation results in excessive interferon gamma production by effector lymphocytes that drive pathology. [Cell Rep] Full Article | Graphical Abstract | Press Release

Docosahexaenoic Acid Alleviates Atopic Dermatitis by Generating Treg and IL-10/TGF-β-Modified Macrophage via TGF-β Dependent Mechanism
Investigators examined whether docosahexaenoic acid (DHA) suppresses allergic reactions and up-regulates the generation of CD4+Foxp3+ T cells. They also examined the effects of transfusing IL-10/TGF-β-modified macrophages treated with DHA into a mouse model of atopic dermatitis. [J Invest Dermatol] Abstract

Mice Lacking Axl and Mer Tyrosine Kinase Receptors Are Susceptible to Experimental Autoimmune Orchitis Induction
Investigators aimed to determine the role of Axl and Mer receptor tyrosine kinases in maintaining the systemic tolerance to male germ cell antigens using the experimental autoimmune orchitis model. [Immunol Cell Biol] Abstract

A Pneumocyte-Macrophage Paracrine Lipid Axis Drives the Lung Toward Fibrosis
Scientists demonstrate that oxidized phospholipids accumulate within alveolar macrophages (AM) after bleomycin injury, and that murine and human AMs treated with oxidized phosphatidylcholine become polarized along an M2 phenotype and display enhanced production of TGF-β1. [Am J Respir Cell Mol Biol]

Novel and Enhanced Anti-Melanoma DNA Vaccine Targeting the Tyrosinase Protein Inhibits Myeloid-Derived Suppressor Cells and Tumor Growth in a Syngeneic Prophylactic and Therapeutic Murine Model
Scientists investigated the role of myeloid-derived suppressor cells in immune suppression of T cells in an antigen-specific B16 melanoma murine system utilizing a novel synthetic tyrosinase DNA vaccine therapy in both prophylactic and therapeutic models. [Cancer Gene Ther] Abstract | Press Release
