TOP STORYUsing RNA phage Qβ-derived virus-like particles as a model antigen, scientists found that antigen-specific B cells were the dominant antigen-presenting cells that initiated naive CD4+ T cell activation. [Immunity] Abstract | Graphical Abstract | |

PUBLICATIONS(Ranked by impact factor of the journal)Investigators found that some B cells generated IgD-secreting plasma cells following early exposure to external soluble antigens such as food proteins. Secreted IgD targeted basophils by interacting with the CD44-binding protein galectin-9. [Immunity] Abstract | Graphical Abstract Researchers showed, using RNAseq and in vitro and in vivo analyses, signals that are required for promoting B2R cell numbers and effector function in autoimmune mice. [Nat Commun] Full Article The authors showed that the transcription factor Blimp-1 is a crucial regulator of the Foxp3+RORγt+ regulatory T cell subset. The intrinsic expression of Blimp-1 in these cells is required to prevent production of Th17-associated cytokines. [Cell Rep] Full Article | Graphical Abstract Although liver tissue-resident memory T (Trm) cells were found in naive mice, their presence was dictated by antigen specificity and required IL-15. Liver Trm cells also formed after adoptive transfer of in vitro-activated but not naive CD8+ T cells, indicating that activation was essential but that antigen presentation within the liver was not obligatory. [Cell Rep] Full Article | Graphical Abstract Conjugated linoleic acid (CLA) supplementation significantly worsened colorectal tumor formation induced by azoxymethane and dextran sodium sulfate by inducing macrophage and T-cell-producing TGF-β via PPAR-γ activation. [Mucosal Immunol] Abstract IL-33 Drives the Antitumor Effects of Dendritic Cells via the Induction of Tc9 Cells Researchers demonstrated that the addition of interleukin (IL)-33 potently promotes the induction of Tc9 cells by dendritic cells in vitro and in vivo. [Cell Mol Immunol] Abstract An analysis of antibody-secreting cells revealed that a large amount of anti-(4-hydroxy-3-nitrophenyl)acetyl IgM antibodies with few somatic hypermutations is secreted during the recall response, indicating that only non-germinal center memory B cells have terminal differentiation potential. [Sci Rep] Full Article The partial depletion of CD206+ M2-like enhanced UCP1 expression in inguinal white adipose tissue (ingWAT), as shown by immunostaining, and also upregulated the expression of Ucp1 and other browning-related marker genes in ingWAT after cold exposure. [Sci Rep] Full Article Researchers investigated how one calcitriol dose plus vitamin D3 reverses experimental autoimmune encephalomyelitis, a multiple sclerosis model. This protocol rapidly increased CD4+ T cell Ikzf2 transcripts, Helios protein, and CD4+Helios+FoxP3+ T regulatory cells.

REVIEWST Helper Cell Differentiation, Heterogeneity, and Plasticity Naïve CD4 T cells, on activation, differentiate into distinct T helper (Th) subsets that produce lineage-specific cytokines. By producing unique sets of cytokines, effector Th subsets play critical roles in orchestrating immune responses to a variety of infections and are involved in the pathogenesis of many inflammatory diseases including autoimmunity, allergy, and asthma.

INDUSTRY NEWSNobel Prize for Medicine Goes to Cancer Immune Therapy Pioneers Immunologists James P. Allison and Tasuku Honjo have won this year’s Nobel Prize in Physiology or Medicine for their pioneering work in the relatively new field of cancer immunotherapy. [Scientific American] Press Release Hitachi Chemical Advanced Therapeutics Solutions, LLC announced that they have signed a three-year clinical manufacturing agreement with GSK. Under the agreement, HCATS will manufacture GSK’s SPEAR T-cell receptor therapy targeting NY-ESO-1 for the US, Canadian and European trials. [Hitachi Chemical Advanced Therapeutics Solutions, LLC (Business Wire, Inc.)] Press Release Kite and HiFiBiO Therapeutics announced the companies have entered into a research collaboration and license agreement to develop technology supporting the discovery of neoantigen-reactive for the potential treatment of various cancers, including solid tumors. [HiFiBiO Therapeutics] Press Release UCI School of Medicine researchers have been awarded a $3.4 million grant by the National Cancer Institute (NCI) as part of the Beau Biden Cancer Moonshot initiative.

POLICY NEWSMajor Publishers Sue ResearchGate over Copyright Infringement Two journal publishers have launched legal proceedings in the United States against academic-networking site ResearchGate for copyright infringement. [Nature News] Editorial Mr Smits Goes to Washington: Architect of Bold European Open-Access Plan Hopes to Garner US Support A month after European funders launched the ‘Plan S’ initiative to demand immediate open access to scientific literature in the next two years, the plan’s creators have revealed more details about their bold scheme — and are hurriedly trying to get support from US policymakers. [Nature News] Editorial Brazil’s Presidential Election Could Savage Its Science A populist surge from a right-wing presidential candidate in Brazil that is threatening to upend the country’s politics could have huge impacts on research budgets and environmental policies.
