Abstract: Tumour necrosis factor (TNF) is an inflammatory cytokine produced in response to viral infections that promotes the recruitment and activation of leukocytes to sites of infection. This TNF- based host response is essential to limit virus spreading, thus poxviruses have evolutionarily adopted diverse molecular mechanisms to counteract TNF antiviral action. These include the expression of poxvirus-encoded soluble receptors or proteins able to bind and neutralize TNF and other members of the TNF ligand superfamily, acting as decoy receptors. This article reviews in detail the various TNF decoy receptors identified to date in the genomes from different poxvirus species, with a special focus on their impact on poxvirus pathogenesis and their potential use as therapeutic molecules.

The Function of CD27 Costimulation in the Activation and Fate Decisions of CD8+ T Cells
The function of CD27 costimulation in the activation and fate decisions of CD8+ T cells Han Dong Zhengzhou, Henan Province, China B.Sc, Zhejing University, 2009 A Dissertation presented to the Graduate Faculty of the University of Virginia in Candidacy for the Degree of Doctor of Philosophy Department of Experimental Pathology University of Virginia May 2015 ! i! Abstract CD8+ cytotoxic T lymphocytes are critical components of adaptive immunity against a variety of intracellular pathogens, and can play a key role in the control of tumors. Effective vaccination strategies against viral infections and tumors will likely require the development of potent CD8+ T cell responses, which are constituted by the expansion of robust primary CD8+ T cell populations and the establishment of long-lasting memory. Fully functional CD8+ T cell responses are highly dependent upon CD4+ helper T cells and Signal 3 inflammatory cytokine pathways. CD4+ T cells have been demonstrated to play a critical role in inducing the expression of CD70, the ligand for CD27, on dendritic cells. However, it is not clear to what extent the ‘help’ provided by CD4+ T cells is manifest via CD70, or how CD70-mediated stimulation of CD8+ T cells is integrated with signals that emanate from Signal 3 pathways, such as type-1 interferon (IFN-1) and IL- 12. In this work, by enforcing or abrogating CD27 function by genetic or protein intervention in murine models, we sought to identify the function of CD27 costimulation in the activation and fate decisions of CD8+ T cells, to determine the extent it resembles CD4+ T cell help, and how inflammation impacts the relative importance of CD70-CD27 interactions in CD8+ T cell primary responses and CD8+ T cell memory. -

A Computational Systems Approach to Elucidate New Mechanisms Involved in Progressive Lung Disease by Katy Norman A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy (Biomedical Engineering) in the University of Michigan 2020 Doctoral Committee: Assistant Professor Kelly Arnold, Chair Professor Jeffrey Curtis Professor Jennifer Linderman Professor Bethany Moore Professor David Sept Katy C. Norman [email protected] ORCID iD: 0000-0001-8841-0212 © Katy C. Norman 2020 Acknowledgements When I look back on myself in 2015 as I just entered the PhD program, I have to give a little laugh about all the surprises and changes that have happened along the way. I have grown more than I could ever have imagined – I have become so much more comfortable and confident in my communication skills, in my scientific skills, and in myself. These changes and this growth could not have happened without my huge support network, and I am honored to have the chance to thank everyone for what they have given me and for what they have helped me achieve. I would first like to thank my adviser, Kelly Arnold, for giving me a chance to try out computational systems biology research when I had absolutely no background in the field coming in. I appreciate how you were easily able to create a space where I felt comfortable to learn, to ask questions, and to make mistakes as I worked towards gaining expertise in this field. Thank you for always being there for me with extra support when my nerves were getting the best of me before big presentations or before a big deadline, and for supporting my involvement in activities outside of the lab as well. -

Johnson 1,2,3,* 1 Program in Cancer Biology, Vanderbilt University, Nashville, TN 37232, USA; [email protected] 2 Vanderbilt Center for Bone Biology, Department of Medicine, Division of Clinical Pharmacology, Vanderbilt University Medical Center, Nashville, TN 37232, USA 3 Department of Medicine, Division of Clinical Pharmacology, Vanderbilt University Medical Center, Nashville, TN 37232, USA * Correspondence: [email protected]; Tel.: +1-615-875-8965 Received: 14 December 2019; Accepted: 29 January 2020; Published: 31 January 2020 Abstract: Breast cancer cells have a high predilection for skeletal homing, where they may either induce osteolytic bone destruction or enter a latency period in which they remain quiescent. Breast cancer cells produce and encounter autocrine and paracrine cytokine signals in the bone microenvironment, which can influence their behavior in multiple ways. For example, these signals can promote the survival and dormancy of bone-disseminated cancer cells or stimulate proliferation. The interleukin-6 (IL-6) cytokine family, defined by its use of the glycoprotein 130 (gp130) co-receptor, includes interleukin-11 (IL-11), leukemia inhibitory factor (LIF), oncostatin M (OSM), ciliary neurotrophic factor (CNTF), and cardiotrophin-1 (CT-1), among others. These cytokines are known to have overlapping pleiotropic functions in different cell types and are important for cross-talk between bone-resident cells. IL-6 cytokines have also been implicated in the progression and metastasis of breast, prostate, lung, and cervical cancer, highlighting the importance of these cytokines in the tumor–bone microenvironment. This review will describe the role of these cytokines in skeletal remodeling and cancer progression both within and outside of the bone microenvironment. -

Evolutionary Divergence and Functions of the Human Interleukin (IL) Gene Family Chad Brocker,1 David Thompson,2 Akiko Matsumoto,1 Daniel W

The term ‘interleukin’ (IL) has been used to describe a group of cytokines with complex immunomodulatory functions — including cell proliferation, maturation, migration and adhesion. These cytokines also play an important role in immune cell differentiation and activation. Determining the exact function of a particular cytokine is complicated by the influence of the producing cell type, the responding cell type and the phase of the immune response. ILs can also have pro- and anti-inflammatory effects, further complicating their characterisation. These molecules are under constant pressure to evolve due to continual competition between the host’s immune system and infecting organisms; as such, ILs have undergone significant evolution. This has resulted in little amino acid conservation between orthologous proteins, which further complicates the gene family organisation. Within the literature there are a number of overlapping nomenclature and classification systems derived from biological function, receptor-binding properties and originating cell type. -

Barnstable Department Head of Neural and Behavioral Sciences Professor of Neural and Behavioral Sciences Patricia J. McLaughlin Professor of Neural and Behavioral Sciences Director of Graduate Program in Anatomy *Signatures are on file in the Graduate School. ii ABSTRACT The retina is an immune-privileged organ. Many autoimmune diseases, such as AMD, glaucoma, and diabetic retinopathy, are caused by excessive inflammatory responses targeting self-tissue. The physiological functions of extracellular and intracellular signaling molecules of immune responses have been well characterized. The epigenetic aspects of these molecules in the retina, however, have not been well elucidated. In this study, we examined the expression of selected immune-related genes, and their transcriptional accessibility via epigenetic mapping, cluster analysis, and RT-PCR. Among these genes, interleukin receptor related genes and intracellular signaling molecules exhibit higher transcriptional accessibility. Epigenetic mapping of the toll-like receptor (TLR) family revealed that 3 out of 13 TLRs exhibit H3K4me2 accumulation during retina development, suggesting that TLR2, TLR3, and TLR9 are the only TLR members expressed in the retina. Most of the NF-κB signaling molecules exhibited transcriptional accessibility, implying their essential roles in inflammatory regulation during retina maturation. -
Updated November 2019 KIT Mutation the KIT Gene Is Associated With
Updated November 2019 KIT Mutation The KIT gene is associated with autosomal dominant piebaldism, gastrointestinal stromal tumors (GISTs), and familial mastocytosis.1-3 The type of mutation identified in the KIT gene determines the symptoms/cancer risks that the individual may have. Pathogenic loss-of-function (LOF) mutations in the KIT gene are generally only associated with Piebaldism. However, pathogenic gain of function mutations in the KIT gene are associated with systemic mastocytosis and gastrointestinal stromal tumors.4,5 Piebaldism: This is a rare condition characterized by the patchy absence of melanocytes in certain areas of the skin and hair. Melanocytes produce the pigment melanin, which contributes to hair, eye, and skin color. The absence of melanocytes leads to patches of skin and hair that are lighter than normal. These unpigmented areas are typically present at birth and do not increase in size or number.6-8 Gastrointestinal stromal tumors (GIST): GISTs are tumors that occur in the gastrointestinal tract, most commonly in the stomach or small intestine. Small tumors may cause no signs or symptoms. However, some people with GISTs may experience pain or swelling in the abdomen, nausea, vomiting, loss of appetite, or weight loss. These tumors can be cancerous (malignant) or noncancerous (benign). Mastocytosis: This is a blood disorder that occurs when white blood cells called mast cells accumulate in one or more tissues (most commonly in the bone marrow). Mast cells normally trigger inflammation during an allergic reaction. When an environmental trigger activates mast cells, they release proteins that signal an immune response. In systemic mastocytosis, excess mast cells mean more proteins are being released in the tissues where the cells accumulate, leading to an increased immune response.
