    WDFY4 is required for cross-presentation in response to viral and tumor antigens (2018)
    American Association for the Advancement of Science (AAAS)
    In: Science
    Details
    Publication Date: 2018-11-09
    Description: During the process of cross-presentation, viral or tumor-derived antigens are presented to CD8 + T cells by Batf3- dependent CD8α + /XCR1 + classical dendritic cells (cDC1s). We designed a functional CRISPR screen for previously unknown regulators of cross-presentation, and identified the BEACH domain–containing protein WDFY4 as essential for cross-presentation of cell-associated antigens by cDC1s in mice. However, WDFY4 was not required for major histocompatibility complex class II presentation, nor for cross-presentation by monocyte-derived dendritic cells. In contrast to Batf3 –/– mice, Wdfy4 –/– mice displayed normal lymphoid and nonlymphoid cDC1 populations that produce interleukin-12 and protect against Toxoplasma gondii infection. However, similar to Batf3 –/– mice, Wdfy4 –/– mice failed to prime virus-specific CD8 + T cells in vivo or induce tumor rejection, revealing a critical role for cross-presentation in antiviral and antitumor immunity.

    Role for Spi-C in the development of red pulp macrophages and splenic iron homeostasis (2008)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2008-11-28
    Description: Tissue macrophages comprise a heterogeneous group of cell types differing in location, surface markers and function. Red pulp macrophages are a distinct splenic subset involved in removing senescent red blood cells. Transcription factors such as PU.1 (also known as Sfpi1) and C/EBPalpha (Cebpa) have general roles in myelomonocytic development, but the transcriptional basis for producing tissue macrophage subsets remains unknown. Here we show that Spi-C (encoded by Spic), a PU.1-related transcription factor, selectively controls the development of red pulp macrophages. Spi-C is highly expressed in red pulp macrophages, but not monocytes, dendritic cells or other tissue macrophages. Spic(-/-) mice have a cell-autonomous defect in the development of red pulp macrophages that is corrected by retroviral Spi-C expression in bone marrow cells, but have normal monocyte and other macrophage subsets. Red pulp macrophages highly express genes involved in capturing circulating haemoglobin and in iron regulation. Spic(-/-) mice show normal trapping of red blood cells in the spleen, but fail to phagocytose these red blood cells efficiently, and develop an iron overload localized selectively to splenic red pulp. Thus, Spi-C controls development of red pulp macrophages required for red blood cell recycling and iron homeostasis.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756102/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756102/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kohyama, Masako -- Ise, Wataru -- Edelson, Brian T -- Wilker, Peter R -- Hildner, Kai -- Mejia, Carlo -- Frazier, William A -- Murphy, Theresa L -- Murphy, Kenneth M -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Jan 15;457(7227):318-21. doi: 10.1038/nature07472.

    The AP-1 transcription factor Batf controls T(H)17 differentiation (2009)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2009-07-07
    Description: Activator protein 1 (AP-1, also known as JUN) transcription factors are dimers of JUN, FOS, MAF and activating transcription factor (ATF) family proteins characterized by basic region and leucine zipper domains. Many AP-1 proteins contain defined transcriptional activation domains, but BATF and the closely related BATF3 (refs 2, 3) contain only a basic region and leucine zipper, and are considered to be inhibitors of AP-1 activity. Here we show that Batf is required for the differentiation of IL17-producing T helper (T(H)17) cells. T(H)17 cells comprise a CD4(+) T-cell subset that coordinates inflammatory responses in host defence but is pathogenic in autoimmunity. Batf(-/-) mice have normal T(H)1 and T(H)2 differentiation, but show a defect in T(H)17 differentiation, and are resistant to experimental autoimmune encephalomyelitis. Batf(-/-) T cells fail to induce known factors required for T(H)17 differentiation, such as RORgamma t (encoded by Rorc) and the cytokine IL21 (refs 14-17). Neither the addition of IL21 nor the overexpression of RORgamma t fully restores IL17 production in Batf(-/-) T cells. The Il17 promoter is BATF-responsive, and after T(H)17 differentiation, BATF binds conserved intergenic elements in the Il17a-Il17f locus and to the Il17, Il21 and Il22 (ref. 18) promoters. These results demonstrate that the AP-1 protein BATF has a critical role in T(H)17 differentiation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2716014/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2716014/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schraml, Barbara U -- Hildner, Kai -- Ise, Wataru -- Lee, Wan-Ling -- Smith, Whitney A-E -- Solomon, Ben -- Sahota, Gurmukh -- Sim, Julia -- Mukasa, Ryuta -- Cemerski, Saso -- Hatton, Robin D -- Stormo, Gary D -- Weaver, Casey T -- Russell, John H -- Murphy, Theresa L -- Murphy, Kenneth M -- AI035783/AI/NIAID NIH HHS/ -- AR049293/AR/NIAMS NIH HHS/ -- GM07200/GM/NIGMS NIH HHS/ -- HG00249/HG/NHGRI NIH HHS/ -- R01 HG000249/HG/NHGRI NIH HHS/ -- R01 HG000249-20/HG/NHGRI NIH HHS/ -- T32 GM008802/GM/NIGMS NIH HHS/ -- T32 GM008802-08/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2009 Jul 16;460(7253):405-9. doi: 10.1038/nature08114.

    A genomic regulatory element that directs assembly and function of immune-specific AP-1-IRF complexes (2012)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2012-09-18
    Description: Interferon regulatory factor 4 (IRF4) and IRF8 regulate B, T, macrophage, and dendritic cell differentiation. They are recruited to cis-regulatory Ets-IRF composite elements by PU.1 or Spi-B. How these IRFs target genes in most T cells is enigmatic given the absence of specific Ets partners. Chromatin immunoprecipitation sequencing in T helper 17 (T(H)17) cells reveals that IRF4 targets sequences enriched for activating protein 1 (AP-1)-IRF composite elements (AICEs) that are co-bound by BATF, an AP-1 factor required for T(H)17, B, and dendritic cell differentiation. IRF4 and BATF bind cooperatively to structurally divergent AICEs to promote gene activation and T(H)17 differentiation. The AICE motif directs assembly of IRF4 or IRF8 with BATF heterodimers and is also used in T(H)2, B, and dendritic cells. This genomic regulatory element and cognate factors appear to have evolved to integrate diverse immunomodulatory signals.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Glasmacher, Elke -- Agrawal, Smita -- Chang, Abraham B -- Murphy, Theresa L -- Zeng, Wenwen -- Vander Lugt, Bryan -- Khan, Aly A -- Ciofani, Maria -- Spooner, Chauncey J -- Rutz, Sascha -- Hackney, Jason -- Nurieva, Roza -- Escalante, Carlos R -- Ouyang, Wenjun -- Littman, Dan R -- Murphy, Kenneth M -- Singh, Harinder -- RC1 AI087266/AI/NIAID NIH HHS/ -- RC4 AI092765/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2012 Nov 16;338(6109):975-80. doi: 10.1126/science.1228309.

    L-Myc expression by dendritic cells is required for optimal T-cell priming (2014)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2014-02-11
    Description: The transcription factors c-Myc and N-Myc--encoded by Myc and Mycn, respectively--regulate cellular growth and are required for embryonic development. A third paralogue, Mycl1, is dispensable for normal embryonic development but its biological function has remained unclear. To examine the in vivo function of Mycl1 in mice, we generated an inactivating Mycl1(gfp) allele that also reports Mycl1 expression. We find that Mycl1 is selectively expressed in dendritic cells (DCs) of the immune system and controlled by IRF8, and that during DC development, Mycl1 expression is initiated in the common DC progenitor concurrent with reduction in c-Myc expression. Mature DCs lack expression of c-Myc and N-Myc but maintain L-Myc expression even in the presence of inflammatory signals such as granulocyte-macrophage colony-stimulating factor. All DC subsets develop in Mycl1-deficient mice, but some subsets such as migratory CD103(+) conventional DCs in the lung and liver are greatly reduced at steady state. Importantly, loss of L-Myc by DCs causes a significant decrease in in vivo T-cell priming during infection by Listeria monocytogenes and vesicular stomatitis virus. The replacement of c-Myc by L-Myc in immature DCs may provide for Myc transcriptional activity in the setting of inflammation that is required for optimal T-cell priming.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3954917/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3954917/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉KC, Wumesh -- Satpathy, Ansuman T -- Rapaport, Aaron S -- Briseno, Carlos G -- Wu, Xiaodi -- Albring, Jorn C -- Russler-Germain, Emilie V -- Kretzer, Nicole M -- Durai, Vivek -- Persaud, Stephen P -- Edelson, Brian T -- Loschko, Jakob -- Cella, Marina -- Allen, Paul M -- Nussenzweig, Michel C -- Colonna, Marco -- Sleckman, Barry P -- Murphy, Theresa L -- Murphy, Kenneth M -- P30 CA091842/CA/NCI NIH HHS/ -- P30 CA91842/CA/NCI NIH HHS/ -- R01 AI024157/AI/NIAID NIH HHS/ -- R01 AI047829/AI/NIAID NIH HHS/ -- T32 AI007163/AI/NIAID NIH HHS/ -- T32 GM007200/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2014 Mar 13;507(7491):243-7. doi: 10.1038/nature12967.

    BATF-JUN is critical for IRF4-mediated transcription in T cells (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-09-21
    Description: Interferon regulatory factor 4 (IRF4) is an IRF family transcription factor with critical roles in lymphoid development and in regulating the immune response. IRF4 binds DNA weakly owing to a carboxy-terminal auto-inhibitory domain, but cooperative binding with factors such as PU.1 or SPIB in B cells increases binding affinity, allowing IRF4 to regulate genes containing ETS-IRF composite elements (EICEs; 5'-GGAAnnGAAA-3'). Here we show that in mouse CD4(+) T cells, where PU.1/SPIB expression is low, and in B cells, where PU.1 is well expressed, IRF4 unexpectedly can cooperate with activator protein-1 (AP1) complexes to bind to AP1-IRF4 composite (5'-TGAnTCA/GAAA-3') motifs that we denote as AP1-IRF composite elements (AICEs). Moreover, BATF-JUN family protein complexes cooperate with IRF4 in binding to AICEs in pre-activated CD4(+) T cells stimulated with IL-21 and in T(H)17 differentiated cells. Importantly, BATF binding was diminished in Irf4(-/-) T cells and IRF4 binding was diminished in Batf(-/-) T cells, consistent with functional cooperation between these factors. Moreover, we show that AP1 and IRF complexes cooperatively promote transcription of the Il10 gene, which is expressed in T(H)17 cells and potently regulated by IL-21. These findings reveal that IRF4 can signal via complexes containing ETS or AP1 motifs depending on the cellular context, thus indicating new approaches for modulating IRF4-dependent transcription.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3537508/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3537508/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Li, Peng -- Spolski, Rosanne -- Liao, Wei -- Wang, Lu -- Murphy, Theresa L -- Murphy, Kenneth M -- Leonard, Warren J -- ZIA HL005402-20/Intramural NIH HHS/ -- ZIA HL005402-21/Intramural NIH HHS/ -- ZIA HL005408-05/Intramural NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Oct 25;490(7421):543-6. doi: 10.1038/nature11530.

    Compensatory dendritic cell development mediated by BATF-IRF interactions (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-09-21
    Description: The AP1 transcription factor Batf3 is required for homeostatic development of CD8alpha(+) classical dendritic cells that prime CD8 T-cell responses against intracellular pathogens. Here we identify an alternative, Batf3-independent pathway in mice for CD8alpha(+) dendritic cell development operating during infection with intracellular pathogens and mediated by the cytokines interleukin (IL)-12 and interferon-gamma. This alternative pathway results from molecular compensation for Batf3 provided by the related AP1 factors Batf, which also functions in T and B cells, and Batf2 induced by cytokines in response to infection. Reciprocally, physiological compensation between Batf and Batf3 also occurs in T cells for expression of IL-10 and CTLA4. Compensation among BATF factors is based on the shared capacity of their leucine zipper domains to interact with non-AP1 factors such as IRF4 and IRF8 to mediate cooperative gene activation. Conceivably, manipulating this alternative pathway of dendritic cell development could be of value in augmenting immune responses to vaccines.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482832/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3482832/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tussiwand, Roxane -- Lee, Wan-Ling -- Murphy, Theresa L -- Mashayekhi, Mona -- KC, Wumesh -- Albring, Jorn C -- Satpathy, Ansuman T -- Rotondo, Jeffrey A -- Edelson, Brian T -- Kretzer, Nicole M -- Wu, Xiaodi -- Weiss, Leslie A -- Glasmacher, Elke -- Li, Peng -- Liao, Wei -- Behnke, Michael -- Lam, Samuel S K -- Aurthur, Cora T -- Leonard, Warren J -- Singh, Harinder -- Stallings, Christina L -- Sibley, L David -- Schreiber, Robert D -- Murphy, Kenneth M -- AI076427-02/AI/NIAID NIH HHS/ -- P30 CA91842/CA/NCI NIH HHS/ -- R01 AI036629/AI/NIAID NIH HHS/ -- R01 AI076427/AI/NIAID NIH HHS/ -- R01 CA043059/CA/NCI NIH HHS/ -- T32 AI007163/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- England -- Nature. 2012 Oct 25;490(7421):502-7. doi: 10.1038/nature11531.

    Batf3 deficiency reveals a critical role for CD8alpha+ dendritic cells in cytotoxic T cell immunity (2008)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2008-11-15
    Description: Although in vitro observations suggest that cross-presentation of antigens is mediated primarily by CD8alpha+ dendritic cells, in vivo analysis has been hampered by the lack of systems that selectively eliminate this cell lineage. We show that deletion of the transcription factor Batf3 ablated development of CD8alpha+ dendritic cells, allowing us to examine their role in immunity in vivo. Dendritic cells from Batf3-/- mice were defective in cross-presentation, and Batf3-/- mice lacked virus-specific CD8+ T cell responses to West Nile virus. Importantly, rejection of highly immunogenic syngeneic tumors was impaired in Batf3-/- mice. These results suggest an important role for CD8alpha+ dendritic cells and cross-presentation in responses to viruses and in tumor rejection.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756611/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2756611/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hildner, Kai -- Edelson, Brian T -- Purtha, Whitney E -- Diamond, Mark -- Matsushita, Hirokazu -- Kohyama, Masako -- Calderon, Boris -- Schraml, Barbara U -- Unanue, Emil R -- Diamond, Michael S -- Schreiber, Robert D -- Murphy, Theresa L -- Murphy, Kenneth M -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2008 Nov 14;322(5904):1097-100. doi: 10.1126/science.1164206.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pathology and Immunology, Washington University School of Medicine, 660 South Euclid Avenue, St. Louis, MO 63110, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19008445" target="_blank"〉PubMed〈/a〉

    Notes: The 1 3Σ+g–a 3Σ+u transition of 6Li2 has been observed via collisionally induced fluorescence, excited by visible lines of an argon-ion laser and detected at high resolution with a Fourier–transform spectrometer in the 8200–10 100 cm−1 region. By combining the results with previously obtained data on 7Li2 [F. Martin, R. Bacis, J. Vergès, C. Linton, G. Bujin, C. H. Cheng, and E. Stad, Spectrochim. Acta Part A 44, 1369 (1988)], an accerate, isotopically consistent description of both states has been obtained for 1≤v'≤7 and 0≤v‘≤7. Equilibrium constants, Rydberg-Klein-Rees potential curves, and dissociation energies have been determined and found to be in good agreement with ab initio calculations. From the analysis, the following positions and dissociation energies of the two states were found. For 1 3Σ+g, Te (cm−1) is 16 328.8(1.7) and De (cm−1) is 7091.6(1.2). For a 3Σ+u, Te (cm−1) is 8183.8(1.5) and De (cm−1) is 333(1).
