TOP STORYScientists found that the eukaryotic initiation factor 2α (eIF2α) kinase heme-regulated inhibitor controls NOD1 signalosome folding and activation through a process requiring eIF2α, the transcription factor ATF4, and the heat shock protein HSPB8. [Science] Abstract | Graphical Abstract | |

PUBLICATIONS(Ranked by impact factor of the journal)Researchers identified a group 2 innate lymphoid cell (ILC2) subpopulation that could convert into interleukin-17 (IL-17)-producing NKp44− ILC3-like cells. [Nat Immunol] Abstract Investigators integrated gene expression and chromatin accessibility data to infer regulatory interactions between transcription factors and genes within intestinal type 1, 2, and 3 innate lymphoid cell subsets. [Immunity] Abstract The authors examined the impact of the microbiota on CD8+ T cell memory. Antigen-activated CD8+ T cells transferred into germ-free mice failed to transition into long-lived memory cells and had transcriptional impairments in core genes associated with oxidative metabolism. [Immunity] Abstract | Graphical Abstract Investigators showed an important role for iron in inducing cyclin E and B cell proliferation. They found that iron-deficient individuals exhibited a significantly reduced antibody response to the measles vaccine when compared to iron-normal controls. [Nat Commun] Full Article Fas Signaling-Mediated TH9 Cell Differentiation Favors Bowel Inflammation and Antitumor Functions Scientists showed that Fas promoted TH9 cell differentiation by activating NF-κB via Ca2+-dependent PKC-β activation. [Nat Commun] Full Article Innate Lymphoid Cells in the Induction of Obesity Researchers showed that Il2rg−/−Rag2−/− mice lacking all lymphocytes were resistant to diet-induced obesity. Transplantation of bone marrow cells from Rag2−/− mice, which lack only acquired immune cells, into Il2rg−/−Rag2−/− mice abolished this resistance, indicating a role for innate lymphoid cells in this process. [Cell Rep] Full Article | Graphical Abstract The authors showed that the nitric oxide synthase cofactor tetrahydrobiopterin modulated IL-1β production and key aspects of metabolic remodeling in activated murine macrophages via NO production. [Cell Rep] Full Article | Graphical Abstract Using an established mouse model of colitis-associated cancer, scientists showed that elongation factor Tu GTP binding domain containing 2 (Eftud2) was constantly overexpressed in colonic tissues as well as infiltrating macrophages. [Mucosal Immunol] Full Article Researchers showed that high ZEB1 expression in hypoxic cervical cancer cell islets was positively correlated with CD163+ tumor-associated macrophage accumulation. [Cell Death Dis] Full Article E1A Oncogene Induced Sensitization to NK Cell Induced Apoptosis Requires PIDD and Caspase-2 Expression of the adenovirus E1A oncogene sensitized tumor cells to innate immune rejection by NK cells. This increased NK sensitivity was only partly explained by an E1A-induced increase in target cell surface expression of NKG2D ligands.

POLICY NEWSMexican President Eases Up on Researchers’ Travel Rules A month after announcing increased austerity measures on international travel for scientists, Mexico’s National Council of Science and Technology announced that at least one restriction would be loosened. Scientists would not require presidential approval for every trip abroad. [The Scientist] Editorial Hungarian Law Wrests Control of Research from Scientific Academy The Hungarian Parliament passed a bill that takes control for funding Hungarian research bodies away from the Hungarian Academy of Sciences and gives it to a government-led committee, Reuters reports.
