PUBLICATIONS(Ranked by impact factor of the journal)Gut Microbiome-Mediated Bile Acid Metabolism Regulates Liver Cancer via NKT Cells A selective increase of hepatic CXCR6+ natural killer T (NKT) cells was observed, independent of mouse strain, gender, or presence of liver tumors. The accumulated hepatic NKT cells showed an activated phenotype and produced more interferon-γ upon antigen stimulation. [Science] Abstract | Press Release | Graphical Abstract CAR T Cell-Induced Cytokine Release Syndrome Is Mediated by Macrophages and Abated by IL-1 Blockade Scientists report a murine model of cytokine release syndrome that develops within two-three days of chimeric antigen receptor (CAR) T cell infusion and that is potentially lethal and responsive to interleukin-6 receptor blockade. [Nat Med] Abstract Scientists described a mouse model recapitulating key features of cytokine-release syndrome (CRS) and neurotoxicity. In humanized mice with high leukemia burden, chimeric antigen receptor-modified T (CAR T) cell-mediated clearance of cancer triggered high fever and elevated IL-6 levels, which are hallmarks of CRS. [Nat Med] Abstract Testosterone Is an Endogenous Regulator of BAFF and Splenic B Cell Number Investigators showed that testosterone regulates the cytokine BAFF, an essential survival factor for B cells. [Nat Commun] Full Article Induction of Anergic or Regulatory Tumor-Specific CD4+ T Cells in the Tumor-Draining Lymph Node The authors showed, using a genetically engineered lung adenocarcinoma mouse model, that naive tumor-specific CD4+ T cells are activated and proliferate in the tumor-draining lymph node but do not differentiate into effectors or accumulate in tumors. [Nat Commun] Full Article To explore the therapeutic utility of T cell-engaging bispecific antibodies targeting the receptor tyrosine kinase ROR1, which is expressed by tumor cells of various hematologic and solid malignancies, researchers used a bispecific ROR1 × CD3 scFv-Fc format based on a heterodimeric and aglycosylated Fc domain designed for extended circulatory t1/2 and diminished systemic T cell activation. [Proc Natl Acad Sci USA] Abstract | Press Release Researchers showed that equilibrative nucleoside transporter 3 is highly expressed in peripheral T cells and has a key role in maintaining T cell homeostasis by supporting the proliferation and survival of T cells. [Cell Rep] Full Article | Graphical Abstract Scientists find mechanistic interactions between working skeletal muscles and locally recruited neutrophils expressing IL-1β, which supports muscle performance through priming exercise-dependent GLUT4 translocation. [Cell Rep] Full Article | Graphical Abstract iPS-T cells upregulated CD40 ligand (CD40L) expression in response to interleukin-2 and interleukin-15. In the presence of Wilms tumor 1 (WT1) peptide, antigen-specific dendritic cells conditioned by CD4-modified CD40Lhigh iPS-T cells stimulated WT1-specific cytotoxic T lymphocyte priming, which eliminated WT1 peptide-expressing chronic myelogenous leukemia cells in vitro and in vivo. [Stem Cell Reports] Full Article | Graphical Abstract Scientists demonstrated that the overexpression of Rbm47 enabled B cells to facilitate Foxp3+ regulator T-cell induction and reduce the severity of DSS-induced ulcerative colitis. [Cell Mol Immunol] Full Article Critical Role of OX40 in the Expansion and Survival of CD4 T-Cell-Derived Double-Negative T Cells The authors demonstrated that the OX40 molecule was highly expressed on CD4−CD8− double negative (cDNT). The expression of OX40 was necessary to promote proliferation and inhibit apoptosis of cDNT in vivo and in vitro. [Cell Death Dis] Full Article Researchers devised a combination therapy of peptide/MHC tetramers and IL-2/anti-IL-2 monoclonal antibody complexes to generate antigen-specific regulatory T cell (Treg) and maintain them over extended time periods.

INDUSTRY NEWSThe University of Texas MD Anderson Cancer Center and Amgen announced two multi-year collaboration agreements aimed at accelerating development of a variety of Amgen’s early-stage oncology therapies for patients with leukemia, myelodysplastic syndromes, multiple myeloma, small-cell lung cancer, and other non-lung cancers with small-cell histologies. [The University of Texas MD Anderson Cancer Center] Press Release Syndax and Nektar Therapeutics Announce Immuno-Oncology Clinical Trial Collaboration Syndax Pharmaceuticals, Inc. and Nektar Therapeutics announced a non-exclusive, clinical collaboration to evaluate the safety and efficacy of Nektar’s NKTR-214, a CD122-biased agonist, in combination with entinostat, Syndax’s oral, small molecule class 1 specific HDAC inhibitor, in patients with metastatic melanoma who have previously progressed on treatment with an anti-programmed death receptor-1 agent.

POLICY NEWS‘Right-to-Try’ Law Intended to Weaken the FDA, Measure’s Sponsor Says in Blunt Remarks Sen. Ron Johnson, the author of the federal “right-to-try” law signed by President Trump this week, wants to make one thing clear: His new law is meant to weaken the FDA. “This law intends to diminish the FDA’s power over people’s lives, not increase it,” he wrote in a letter to Commissioner Scott Gottlieb. [STAT News] Editorial China to Crack Down on Fraud in Scandal-Hit Scientific Research amid ZTE Wrangle China has issued the first national guidelines to enforce academic integrity in scientific research and vowed to punish academics and institutes for misconduct such as plagiarism and fabrication of data. [South China Morning Post Publishers Ltd] Editorial Sweden Commits to Open Science with New Open-Access Publishing Deal Swedish researchers can now publish their articles in Frontiers’ Open Access journals through a simplified process that covers publishing fees, thanks to a national agreement announced between Frontiers and the National Library of Sweden, on behalf of the organizations participating in the Bibsam Consortium. [American Association for the Advancement of Science] Editorial Europe’s Science Spending Set for Another Big Boost On 7 June, the European Commission will lay out detailed plans for one of the biggest single research programs on the planet. Called Horizon Europe, the program could be worth €97.6 billion between 2021 and 2027, up from about €77 billion for the current seven-year program, Horizon 2020. Its influence, however, will go beyond size. [ScienceInsider] Editorial The Science Candidates: Texas Runoff Loss Leaves Wilson With Bitter Taste This year, ScienceInsider is following a number of candidates with science, technology, engineering, and math backgrounds as they run for a seat in the U.S. House of Representatives. In some districts, science candidates have ended up competing against each other for the right to represent their party in the general election on 6 November. [ScienceInsider] Editorial
