TOP STORY
A Special Population of Regulatory T Cells Potentiates Muscle Repair
Scientists describe a phenotypically and functionally distinct population of Foxp3+CD4+ regulatory T cells that rapidly accumulated in the acutely injured skeletal muscle of mice, just as invading myeloid-lineage cells switched from a proinflammatory to a proregenerative state. [Cell]

PUBLICATIONS ( Ranked by impact factor of the journal)
Hedgehog Signaling Controls T Cell Killing at the Immunological Synapse
The primary cilium, formed in nonhematopoietic cells, is essential for vertebrate Hedgehog (Hh) signaling. Lymphocytes do not form primary cilia, but researchers found and describe here that Hh signaling played an important role in cytotoxic T lymphocyte (CTL) killing. T cell receptor activation, which “prearms” CTLs with cytotoxic granules, also initiated Hh signaling. [Science] Abstract

TIM-4 Glycoprotein-Mediated Degradation of Dying Tumor Cells by Autophagy Leads to Reduced Antigen Presentation and Increased Immune Tolerance
T cell immunoglobulin- and mucin domain-containing molecule-4 (TIM-4) was found to be highly expressed on tumor-associated myeloid cells such as macrophages and dendritic cells and danger-associated molecular patterns released from chemotherapy-damaged tumor cells induced TIM-4 on tumor-associated myeloid cells recruited from bone marrow-derived precursors. [Immunity] Abstract | Graphical Abstract

FoxP3 Acts as a Cotranscription Factor with STAT3 in Tumor-Induced Regulatory T Cells
The authors identified an interleukin-10 (IL-10)-producing FoxP3+ T regulatory cell population that contributes to IL-10-dependent type 2 cytokine bias in breast-cancer patients. [Immunity] Abstract

IL-2 Therapy Promotes Suppressive ICOS+ Treg Expansion in Melanoma Patients
Investigators evaluated Treg population subsets that were induced in patients with melanoma following high-dose IL-2 therapy. They identified a Treg population that was positive for CD4, CD25, Foxp3, and the inducible T cell costimulator (ICOS). [J Clin Invest] Full Article | Press Release

Natural Killer Cell NKG2D and Granzyme B Are Critical for Allergic Pulmonary Inflammation
Researchers investigated the importance of natural killer (NK) cells in house dust mite-triggered allergic pulmonary inflammation. Specifically, they aimed to determine the role of the major NK-cell activating receptor NKG2D and NK-cell effector functions mediated by granzyme B. [J Allergy Clin Immun]

Diacylglycerol Kinase ζ Limits the Generation of Natural Regulatory T Cells
The authors found that loss of diacylglycerol Kinase ζ resulted in increased numbers of thymic CD25+Foxp3CD4+ natural regulatory T (nTreg) cell precursors and Foxp3+CD4+ nTreg cells in a cell-autonomous manner. [Sci Signal] Abstract | Press Release

Antigen-Specific Expansion of Human Regulatory T Cells as a Major Tolerance Mechanism against Mucosal Fungi
Scientists used a sensitive enrichment technology for antigen-reactive T cells to directly compare the conventional vs. regulatory CD4+ T-cell response directed against two ubiquitous mucosal fungi, Aspergillus fumigatus and Candida albicans. [Mucosal Immunol] Abstract

Cross-Talk between Aryl Hydrocarbon Receptor and the Inflammatory Response: A Role for NF-κB
Results show for the first time that NF-κB RelA is a critical component regulating the expression of Aryl hydrocarbon receptor (AhR) and the induction of AhR-dependent gene expression in immune cells illustrating the interaction of AhR and NF-κB signaling. [J Biol Chem] Abstract | Full Article

REVIEWS
Autophagy-Mediated Regulation of Macrophages and Its Applications for Cancer
The authors discuss the role of autophagy in the control of macrophage production at different stages and polarization and discuss how modulating autophagy in tumor-associated macrophages may represent a promising strategy for limiting cancer growth and progression. [Autophagy] Abstract

B Cell Regulation of Anti-Tumor Immune Response
Ongoing experiments in the laboratory indicate that B cells migrate to the site of tumor and acquire expression of immunosuppressive ligands and/or cytokines that contribute to the inhibition of anti-tumor immune response. Significant infiltration of human tumors by Treg cells as well as B cells suggests that observations made in murine systems may be applicable to human tumors as well. [Immunol Res] Abstract

The Oracle of the T Cell
Since December 2013 scientists from around the world can use the “virtual T cell” to test for themselves what happens in the blood cell when receptor proteins are activated on the surface. [University of Freiburg]
