TOP STORY

Functional Innervation of Hepatic iNKT Cells Is Immunosuppressive Following Stroke
Selective immunomodulation of invariant NKT (iNKT) cells with a specific activator (α-galactosylceramide) promoted proinflammatory cytokine production and prevented infections post-stroke. [Science] Abstract

PUBLICATIONS (Ranked by Impact Factor of the Journal)

Acetylcholine-Synthesizing T Cells Relay Neural Signals in a Vagus Nerve Circuit
Researchers identified an acetylcholine-producing, memory phenotype T cell population in mice that is integral to the inflammatory reflex. [Science] Abstract

Notch Signaling Is Necessary for Adult, but not Fetal, Development of RORγt+ Innate Lymphoid Cells
Here researchers identify the chemokine receptor CXCR6 as an additional marker of the development of innate lymphoid cells and show that common lymphoid progenitors lost B cell and T cell potential as they successively acquired expression of the integrin α4β7 and CXCR6. [Nat Immunol] Abstract

Human IL-25- and IL-33-Responsive Type 2 Innate Lymphoid Cells Are Defined by Expression of CRTH2 and CD161
The data identify a unique type of human innate lymphoid cells that provides an innate source of T helper type 2 cytokines. [Nat Immunol] Abstract

An Essential Role of the Transcription Factor GATA-3 for the Function of Regulatory T Cells
Here, researchers have demonstrated an essential role for the transcription factor GATA-3 in controlling regulatory T cell function. [Immunity] Abstract | Press Release

Remodeling of Cortical Actin Where Lytic Granules Dock at Natural Killer Cell Immune Synapses Revealed by Super-Resolution Microscopy
Here researchers used two high-resolution imaging techniques to probe the synaptic organization of natural killer cell receptors and filamentous (F)-actin. [PLoS Biol] Abstract | Press Release

Natural Killer Cell Lytic Granule Secretion Occurs Through a Pervasive Actin Network at the Immune Synapse
The data support a model whereby lytic granules and the actin network are intimately associated during the secretion process and broadly suggest a mechanism for the secretion of large organelles in the context of a cortical actin barrier. [PLoS Biol] Abstract | Press Release

Cytotoxic T Lymphocytes Simultaneously Targeting Multiple Tumor-Associated Antigens to Treat EBV Negative Lymphoma
Researchers describe an approach that allows them to consistently generate, in a single line, cytotoxic T lymphocytes that recognize a wide spectrum of nonviral tumor-associated antigens expressed by human HL/NHL, including Survivin, MAGE-A4, Synovial sarcoma X, preferentially expressed antigen in melanoma and NY-ESO-1. [Mol Ther] Abstract

Wnt5a Skews Dendritic Cell Differentiation to an Unconventional Phenotype with Tolerogenic Features
The results show that the increase in Wnt5a signaling during the differentiation of human dendritic cells from monocytes alters their phenotype and compromises their subsequent capacity to mature in response to TLR-dependent stimuli. [J Immunol] Abstract

Insights into HLA-Restricted T Cell Responses in a Novel Mouse Model of Dengue Virus Infection Point Toward New Implications for Vaccine Design
The results provide new insights into HLA-restricted T cell responses against dengue virus, and researchers describe in this study a novel murine model that allows the investigation of T cell-mediated immune mechanisms relevant to vaccine design. [J Immunol]
Abstract

Retinal Self-Antigen Induces a Predominantly Th1 Effector Response in Axl and Mertk Double-Knockout Mice
To study the molecular mechanism underlying the TAM regulation of APC functions and subsequent effects on the induction of an autoimmune response against the eye, researchers examined CD4 T cell differentiation following retinal self-antigen immunization. [J Immunol] Abstract
