    S-Nitrosylation of Septin2 Exacerbates Aortic Aneurysm and Dissection by Coupling the TIAM1-RAC1 Axis in Macrophages

    Biotin-switch assay combined with liquid chromatography–tandem mass spectrometry was performed to identify the S-nitrosylated proteins in aortic tissue from both patients undergoing surgery for aortic dissection and Apoe−/− mice infused with angiotensin II.

    BCL6 Is Required for the Thymic Development of TCRαβ+CD8αα+ Intraepithelial Lymphocyte Lineage

    Scientists found that Bcl6 deficiency in αβ T cells resulted in the near absence of TCRαβ+CD8αα+ intraepithelial lymphocytes.

    Abstract

    PD-1 and CTLA-4 Blockade Promote CD86-Driven Treg Responses upon Radiotherapy of Lymphocyte-Depleted Cancer in Mice

    Investigators showed in a mouse tumor model representative of human lymphocyte-depleted cancer that radiotherapy enhanced spontaneous priming of thymus-derived regulatory T cells by the tumor.

    Engineered T Cells Secreting Anti-BCMA T Cell Engagers Control Multiple Myeloma and Promote Immune Memory In Vivo

    Researchers undertook a comprehensive preclinical study comparing the therapeutic potential of T cells either expressing second-generation anti-B cell maturation antigen (BCMA) CARs or secreting BCMAxCD3 T cell engagers in a T cell–limiting experimental setting.

    Abstract

    T-Bet+ B Cells Are Activated By and Control Endogenous Retroviruses through TLR-Dependent Mechanisms

    The authors generated mouse-strains where Moloney-Murine Leukemia Virus tagged with GFP infected the mouse germline to analyze the role of genetic, epigenetic, and cell intrinsic restriction factors in endogenous retrovirus activation and control.

    A Hepatic Network of Dendritic Cells Mediates CD4 T Cell Help Outside Lymphoid Organs

    Investigators developed an experimental system to investigate cognate CD4+ and CD8+ T cell responses to a model-antigen expressed de novo in hepatocytes.

    Intracerebellar Injection of Monocytic Immature Myeloid Cells Prevents the Adverse Effects Caused by Stereotactic Surgery in a Model of Cerebellar Neurodegeneration

    Immature myeloid cells were obtained from healthy bone marrow and co-cultured with activated T cells. The proliferation and apoptotic rate of the later were analyzed with Tag-it Violet.

    Tissue-Plasminogen Activator Effects on the Phenotype of Splenic Myeloid Cells in Acute Inflammation

    Using tissue-plasminogen activator-deficient mice, investigators have analyzed the effect of lipopolysaccharide challenge on the phenotype of myeloid cells including neutrophils, macrophages, and dendritic cells in the spleen.

    The Genetic Basis of Autoimmunity Seen through the Lens of T Cell Functional Traits

    Autoimmune disease heritability is enriched in T cell-specific regulatory regions of the genome. Modern-day T cell datasets now enable association studies between single nucleotide polymorphisms and a myriad of molecular phenotypes.

    Regulation of Autoimmune-Mediated Neuroinflammation by Endothelial Cells

    The authors discuss how endothelial cells regulate the migration and the functions of T cells in the CNS both at steady-state and in murine models of neuroinflammation, with a special focus on the anatomical, cellular, and molecular mechanisms implicated in EAE.
