Anthony Carruthers, Ph.D., Dean of the Graduate School of Biomedical Sciences Program in Immunology and Virology January 7, 2015 Dedication This thesis is dedicated to my family. Without their support this journey would have never started. iii Acknowledgements I came to graduate school not to get to a degree; I came here to become a scientist. It is said that the thrill is in the journey, not in the destination. With graduate school, my journey has just started. Many people have participated in my journey, and I take this opportunity to thank them for their unending guidance, support and love, without which I would have never reached this far. “Guru govind dono khade, kaake lagu paaye, Balihari guru aapno, govind diyo bataye” - Kabir Translation - “Guru and God both are here, to whom should I first bow? All glory be unto the guru, path to God who did bestow” I would like to thank foremost, my mentor Dr. Leslie Berg. Leslie is a great scientist, a leader and a mentor. She has always made time to discuss science, plan experiments, encouraged me to think independently and above all interpret data un-biasedly. Most importantly, she put a lot of faith in me and was patient when things did not work for many years; a time during which even I lost faith in myself, but she was undeterred. She once told me that there are three types of experiments - type I gives you a novel biologically relevant outcome, no matter what the result is. With type II experiments you shall learn something about iv biology if they give a certain type of result. While type III experiments are just a re-affirmation of the facts already known. She told me to succeed I must always aim for the type I experiments. She is also a great role model for me in my personal life. She has set a great example of a strong female leader, and demonstrated to me how to establish ones identity. I shall carry forward with me her training, and I hope I shall never forget the life-lessons she has taught me. Someone once told me that you start college as young girls and finish as young ladies. I think my growth was largely stunted till I met Regina Whitehead. She may be the lab manager for everyone else, but to me she has always been my lab mom. She has counseled me at every step, personal or professional. When times were dark, she always showed me the ray of hope. But when I faltered, she helped me see my follies and fix them. I am so much more of a complete person than what I was when I started grad school. No wonder she is my lab mom! Thank you Regina! And as always, what would I do without you? I would also like to thank Amanda Prince, with whom I worked when I first joined the Berg lab. She is an amazing person and a great colleague. After I joined the lab, I started working with Hyun-Mu Shin, a post doc in our lab. He is also a great scientist and epitomizes that nothing is impossible if you really put your heart into it. I would also like to thank Megan Enos, a post-doc in our lab. I would always go up to her with questions, and I think I drove her crazy when I v was qualifying. Right before my qualifying exam, I walked up to her and said “OK Megan, last question for you”. She looked at me amusingly, and I corrected myself “last question, before the exam”. John Evans, Catherine Yin and Wen- Fang Wu also made the Berg lab a very happy place to be. John was also my go to person for all flow queries. The present members of the Berg lab make this an intellectually very stimulating environment to be in. I think I am very fortunate to have Elizabeth Schutten in the lab. She is a very hardworking and sincere student, and has been a great collaborator and a friend. She had also contributed immensely to the LCMV Clone 13 project described in Chapter V. Without her help, harvesting multiple organs from 20 or more mice at a time, doing 100 plate plaque assays and running on flow cytometer for some 16 hours would not have been fun. James Conley is also a great lab mate. He is really mature and usually laughs at Beth and I. I think we are mentally under-developed for him. But nonetheless, I love discussing project ideas with him and really admire this scientific acuity. It’s really fun to be around Hyoung-Soo Cho and Yves Falanga, and they too add a lot of flavor to our lab. A special thank you to Sharlene Hubbard who maintains our mouse colony. She is a great lab member. She has helped me keep records of the numerous lines of mice I have bred, assisted me with genotyping, sacrificing and making breeders. If she wasn’t in the mouse room looking out for me, I would not have been half as productive, as I have been so far. vi I would also like to thank other members of our department. Laurie Kenney, a senior student is a great friend of mine. She once told me “the point of an experiment is to get maximum useful information out”. That’s when I started thinking more critically about my LCMV experiments and as to what all information can be gathered without compromising the quality of the data. I would also like to thank Stephen Waggoner who helped me get started with the LCMV experiments, and was my go to person for all questions, no matter what time of the day or night it was. Steve also inspired me to work hard, read and showed to me that getting a faculty position was not impossible! Brian Stadinski is another great role model. He is extremely focused, dedicated and hardworking. I have learnt a lot from him and he is my late night and Friday evening go to buddy! I would also like to thank Dave Moquin and Kenta Moriwaki. They are great friends, and I would sometimes join them for their Friday night beer session in the break room. Its great to have Stina Urban and Bianca Bautista in our department, both have helped me in my projects, and I have had many wonderful discussions with them. I would also like to thank members of the Kang lab - Nitya Jain, Kavitha Narayan, Nidhi Malhotra, Katelyn Sylvia and Bing Miu. The Kang lab is such a great neighbor, and our go to place for antibodies and reagents. Nitya and Kavitha are one of the most hardworking and intelligent students I have known. They have inspired me to not give up in grad school, and shown to me that if you vii work hard enough, you shall succeed in the end. Katelyn and Bing are my coffee and chat buddies. This acknowledgement would be incomplete without thanking members of my TRAC committee. Ray Welsh, who is also my chair, has mentored me on my LCMV projects. I would just walk into his office and he always made time for me. Mike Brehm was also my go to person for all LCMV questions. I have spammed his inbox many times with my data, and he has always patiently responded to all my queries. Joonsoo Kang has always encouraged me to think a step beyond the obvious. What I liked most about talking to him was that he never gave me an answer, rather he always lead me to it. Of course all this happened before 6 PM, after which the conversations were always more philosophical than scientific.

    Transcription Factor IRF4 Drives Dendritic Cells to Promote Th2 Differentiation

Fixsen5, Harinder Singh4, Roger Sciammas6 & Anne I. Sperling1,2,5 Atopic asthma is an inflammatory pulmonary disease associated with Th2 adaptive immune responses triggered by innocuous antigens. While dendritic cells (DCs) are known to shape the adaptive immune response, the mechanisms by which DCs promote Th2 differentiation remain elusive. Herein we demonstrate that Th2-promoting stimuli induce DC expression of IRF4. Mice with conditional deletion of Irf4 in DCs show a dramatic defect in Th2-type lung inflammation, yet retain the ability to elicit pulmonary Th1 antiviral responses. Using loss- and gain-of-function analysis, we demonstrate that Th2 differentiation is dependent on IRF4 expression in DCs. Finally, IRF4 directly targets and activates the Il-10 and Il-33 genes in DCs. Reconstitution with exogenous IL-10 and IL-33 recovers the ability of Irf4-deficient DCs to promote Th2 differentiation. These findings reveal a regulatory module in DCs by which IRF4 modulates IL-10 and IL-33 cytokine production to specifically promote Th2 differentiation and inflammation. 1 Committee on Molecular Pathogenesis and Molecular Medicine, University of Chicago, 924 E. 57th Street, Chicago, Illinois 60637 USA. 2 Committee on Immunology, University of Chicago, 924 E. 57th Street, Chicago, Illinois 60637 USA. 3 Medical Scientist Training Program, University of Chicago, 924 E.

Although all three factors are expressed from the onset of B-cell development, single deficiency of these factors in B-cell progenitors only mildly impacts on bone marrow B lymphopoiesis. Here we tested whether PU.1 cooperates with IRF factors in regulating early B-cell development. Lack of PU.1 and IRF4 resulted in a partial block in development the pre-B-cell stage. The combined deletion of PU.1 and IRF8 reduced recirculating B-cell numbers. Strikingly, all PU.1/IRF4 and ~ 50% of PU.1/IRF8 double deficient mice developed pre-B-cell acute lymphoblastic leukemia (B-ALL) associated with reduced expression of the established B-lineage tumor suppressor genes, Ikaros and Spi-B. These genes are directly regulated by PU.1/IRF4/IRF8, and restoration of Ikaros or Spi-B expression inhibited leukemic cell growth. In summary, we demonstrate that PU.1, IRF4 and IRF8 cooperate to regulate early B-cell development and to prevent pre-B-ALL formation.

How microglial IRF5 and IRF4 signaling are activated has been elusive. We hypothesized that interleukin-1 receptor associated kinase 4 (IRAK4) phosphorylates and activates IRF5 and IRF4 in ischemic microglia. We aimed to explore the upstream signals of the two IRFs, and to determine how the IRAK4-IRF signaling regulates the expression of inflammatory mediators, and impacts neuropathology. Meth- ods: Spontaneously Immortalized Murine (SIM)-A9 microglial cell line, primary microglia and neurons from C57BL/6 WT mice were cultured and exposed to oxygen-glucose deprivation (OGD), followed by stimulation with LPS or IL-4. An IRAK4 inhibitor (ND2158) was used to examine IRAK40s effects on the phosphorylation of IRF5/IRF4 and the impacts on neuronal morphology by co-immunoprecipitation (Co-IP)/Western blot, ELISA, and immunofluorescence assays. Results: We confirmed that IRAK4 formed a Myddosome with MyD88/IRF5/IRF4, and phosphorylated both IRFs, which subsequently translocated into the nucleus.

CHANG, 1 AND BRYAN VANDER LUGT 1Department of Discovery Immunology, Genentech Inc., South San Francisco, California 94080 4Correspondence: [email protected] The transcription factors IRF4 and IRF8 represent immune-specific members of the interferon regulatory family. They play major roles in controlling the development and functioning of innate and adaptive cells. Genes encoding these factors appear to have been coopted by the immune system via gene duplication and divergence of regulatory and protein coding sequences to enable the acquisition of unique molecular properties and functions. Unlike other members of the IRF family, IRF4 and IRF8 do not activate transcription of Type 1 interferon genes or positively regulate interferon-induced gene expression. Instead, they bind to unusual composite Ets-IRF or AP-1-IRF elements with specific Ets or AP-1 family transcription factors, respectively, and regulate the expression of diverse sets of immune response genes in innate as well as adaptive cells.

Abstract: Interferon regulatory factor-4 (IRF4) and IRF8 regulate differentiation, growth and functions of lymphoid and myeloid cells. Targeted deletion of irf8 in T cells (CD4-IRF8KO) has been shown to exacerbate colitis and experimental autoimmune uveitis (EAU), a mouse model of human uveitis. We therefore generated mice lacking irf4 in T cells (CD4-IRF4KO) and investigated whether expression of IRF4 by T cells is also required for regulating T cells that suppress autoimmune diseases. Surprisingly, we found that CD4-IRF4KO mice are resistant to EAU. Suppression of EAU derived in part from inhibiting pathogenic responses of Th17 cells while inducing expansion of regulatory lymphocytes that secrete IL-10 and/or IL-35 in the eye and peripheral lymphoid tissues. Furthermore, CD4- IRF4KO T cells exhibit alterations in cell metabolism and are defective in the expression of two Citation: Kang, M.; Lee, H.-S.; Choi, Ikaros zinc-finger (IKZF) transcription factors (Ikaros, Aiolos) that are required for lymphocyte J.K.; Yu, C.-R.; Egwuagu, C.E.

Because they tend to develop more vigorous adaptive immune responses than men, women are less susceptible to some infectious diseases but also at higher risk of autoimmunity. The regulation of immune responses by sex-dependent factors probably involves several non-redundant mechanisms.

We now have identified inter- the estradiol/ER␣-dependent DC popula- cyte macrophage–colony-stimulating fac- feron regulatory factor 4 (IRF4), a tran- tion, indicating that an elevated amount tor (GM-CSF) directs the development of scription factor induced by GM-CSF and of IRF4 protein substitutes for ER␣ signal- new dendritic cells (DCs). This pathway is critical for CD11b؉ DC development in ing. Thus at an early stage in the MP influenced by environmental factors, and vivo, as a target of ER␣ signaling during response to GM-CSF, ER␣ signaling in- we previously showed that physiologic this process.
