TOP STORY
Biomarker Predicting Transplant Complications May Be Key to Treating Them
A protein that can be used to predict if a stem cell transplant patient will suffer severe complications may also be the key to preventing those complications. researchers said that blocking the activity of the protein called ST2 offers a potential new treatment for graft-versus host-disease, an immune problem that affects many transplant recipients.

PUBLICATIONS (Ranked by impact factor of the journal)
PI3-Kinase-γ Has a Distinct and Essential Role in Lung-Specific Dendritic Cell Development
The authors showed that the Ras-PI3Kγ-Akt-mTOR signaling axis acted downstream of FLT3L signaling and was required for development of lung CD103+ dendritic cells (DCs) and, to a smaller extent, for lung CD11b+ DCs, but not related DC populations in other non-lymphoid organs. [Immunity] Abstract | Graphical Abstract

The MicroRNA miR-22 Inhibits the Histone Deacetylase HDAC4 to Promote TH17 Cell–Dependent Emphysema
Investigators explored the role of the microRNA miR-22 in emphysema. They found that miR-22 was upregulated in lung myeloid dendritic cells of smokers with emphysema and antigen-presenting cells of mice exposed to smoke or nanoparticulate carbon black through a mechanism that involved the transcription factor NF-κB [Nat Immunol] Abstract | Press Release

Control of Peripheral Tolerance by Regulatory T Cell–Intrinsic Notch Signaling
Researchers found that lineage-specific deletion of components of the Notch pathway enhanced regulatory T cell (Treg cell)–mediated suppression of type 1 helper T cell (TH1 cell) responses and protected against their TH1 skewing and apoptosis. In contrast, expression in Treg cells of a gain-of-function transgene encoding the Notch1 intracellular domain resulted in lymphoproliferation, exacerbated TH1 responses and autoimmunity. [Nat Immunol] Abstract

Eomesodermin-Expressing T-Helper Cells Are Essential for Chronic Neuroinflammation
Scientists revealed that development of this late onset disease depends on cytotoxic T-cell-like CD4+ T cells expressing the T-box transcription factor Eomesodermin (Eomes). T-cell-specific deletion of the Eomes gene remarkably ameliorates the late-onset experimental autoimmune encephalomyelitis. [Nat Commun] Full Article

Conditional Knockdown of BCL2A1 Reveals Rate-Limiting Roles in BCR-Dependent B-Cell Survival
Researchers report on the consequences of conditional knockdown of A1 protein expression using a reverse transactivator-driven approach that highlights a critical role for this Bcl2 family member in the maintenance of mature B-cell homeostasis. [Cell Death Differ] Full Article

The Kinases NDR1/2 Act Downstream of the Hippo Homolog MST1 to Mediate Both Egress of Thymocytes from the Thymus and Lymphocyte Motility
Researchers generated and characterized mice with a T cell–specific double knockout of Ndr1 and Ndr2 (Ndr DKO). Compared with control mice, Ndr DKO mice exhibited a substantial reduction in the number of naïve T cells in their secondary lymphoid organs. [Sci Signal] Abstract

Glutamine-Dependent α-Ketoglutarate Production Regulates the Balance between T Helper 1 Cell and Regulatory T Cell Generation
Researchers showed that exogenous nutrient availability regulated the differentiation of naïve CD4+ T cells into distinct subsets. [Sci Signal] Abstract

MFG-E8 Is Critical for Embryonic Stem Cell-Mediated T Cell Immunomodulation
The molecules and mechanisms pertinent to the low immunogenicity of undifferentiated embryonic stem cells remain poorly understood. Scientists provide evidence that milk fat globule epidermal growth factor 8 (MFG-E8) is a vital mediator in this phenomenon and directly suppresses T cell immune responses. [Stem Cell Reports] Full Article | Graphical Abstract

Modulation of Dendritic Cell Activation and Subsequent Th1 Cell Polarization by Lidocaine
Scientists showed that lidocaine inhibited the production of IL-6, TNFα and IL-12 from dendritic cells in response to toll-like receptor ligands including lipopolysaccharide, poly(I:C) and R837 in a dose-dependent manner. [PLoS One] Full Article

Lenalidomide Enhances the Function of Chimeric Antigen Receptor T Cells against the Epidermal Growth Factor Receptor Variant III by Enhancing Immune Synapses
Researchers constructed a lentiviral vector transducing the chimeric antigen receptor (CAR) that consisted of 3C10-scFv, CD3ζ, CD28 and 4-1BB. The 3C10-CAR-transduced peripheral blood mononuclear cells and CD3+ T cells specifically lysed the glioma cells that express EGFRvIII. [Cancer Gene Ther] Abstract

REVIEWS
Immune Surveillance of the CNS following Infection and Injury
The authors review how the central nervous system (CNS) immunologically discriminates between pathogens and sterile injuries, mobilizes an immune reaction, and, ultimately, regulates local and peripherally-derived immune cells to provide a supportive milieu for tissue repair.
