Viral Infections And Interferons In The Development Of Obesity, Yun Tian, Jordan Jennings, Yuanying Gong, Yongming Sang
Viral Infections And Interferons In The Development Of Obesity, Yun Tian, Jordan Jennings, Yuanying Gong, Yongming Sang
Agricultural and Environmental Sciences Faculty Research
Obesity is now a prevalent disease worldwide and has a multi-factorial etiology. Several viruses or virus-like agents including members of adenoviridae, herpesviridae, slow virus (prion), and hepatitides, have been associated with obesity; meanwhile obese patients are shown to be more susceptible to viral infections such as during influenza and dengue epidemics. We examined the co-factorial role of viral infections, particularly of the persistent cases, in synergy with high-fat diet in induction of obesity. Antiviral interferons (IFNs), as key immune regulators against viral infections and in autoimmunity, emerge to be a pivotal player in the regulation of adipogenesis. In this review, …

Innate immune interferons (IFNs), particularly type I IFNs, are primary mediators regulating animal antiviral, antitumor, and cell-proliferative activity. These antiviral cytokines have evolved remarkable molecular and functional diversity to confront ever-evolving viral threats and physiological regulation. We have annotated IFN gene families across 110 animal genomes, and showed that IFN genes, after originating in jawed fishes, had several significant evolutionary surges in vertebrate species of amphibians, bats and ungulates, particularly pigs and cattle. For example, pigs have the largest but still expanding type I IFN family consisting of nearly 60 IFN-coding genes that encode seven IFN subtypes including multigene subtypes …
Porcine Interferon Complex And Co-Evolution With Increasing Viral Pressure After Domestication, Jordan Jennings, Yongming Sang
Porcine Interferon Complex And Co-Evolution With Increasing Viral Pressure After Domestication, Jordan Jennings, Yongming Sang
Agricultural and Environmental Sciences Faculty Research
Consisting of nearly 60 functional genes, porcine interferon (IFN)-complex represents an evolutionary surge of IFN evolution in domestic ungulate species. To compare with humans and mice, each of these species contains about 20 IFN functional genes, which are better characterized using the conventional IFN-α/β subtypes as examples. Porcine IFN-complex thus represents an optimal model for studying IFN evolution that resulted from increasing viral pressure during domestication and industrialization. We hypothesize and justify that porcine IFN-complex may extend its functionality in antiviral and immunomodulatory activity due to its superior molecular diversity. Furthermore, these unconventional IFNs could even confer some functional and …
Immunogenicity Of Tumor Initiating Stem Cells: Potential Applications In Novel Anticancer Therapy, Durga Khandekar, Suneetha Amara, Venkataswarup Tiriveedhi
Immunogenicity Of Tumor Initiating Stem Cells: Potential Applications In Novel Anticancer Therapy, Durga Khandekar, Suneetha Amara, Venkataswarup Tiriveedhi

Tumor initiating stem cells (TISCs) are a subset of tumor cells, which are implicated in cancer relapse and resistance to chemotherapy. The metabolic programs that drive TISC functions are exquisitely unique and finely-tuned by various oncogene-driven transcription factors to facilitate pro-cancerous adaptive challenges. While this change in TISC metabolic machinery allows for the identification of associated molecular targets with diagnostic and prognostic value, these molecules also have a potential immunological application. Recent studies have shown that these TISC-associated molecules have strong antigenic properties enabling naïve CD8+T lymphocytes to differentiate into cytotoxic effector phenotype with anticancer potential. In spite of the …

Kinetic Analysis And Epitope Mapping Of Monoclonal Antibodies To Salmonella Typhimurium Flagellin Using A Surface Plasmon Resonance Biosensor, Devendra Bhandari, Fur-Chi Chen, Shreya Hamal, Roger C. Bridgman

Salmonella Typhimurium is one of the leading causes of foodborne diseases worldwide. Biosensors and immunoassays utilizing monoclonal antibodies are widely used for the detection and subtyping of S. Typhimurium. However, due to insufficient information on the nature of binding with S. Typhimurium flagellin, the selection of appropriate antibodies for assay development is a cumbersome task. Hence, we aimed to compare the binding kinetics of a panel of monoclonal antibodies and their relative binding sites to flagellin antigen using a surface plasmon resonance biosensor. Initially, the flagellin was captured on the sensor surface through an immobilized anti-flagellin antibody. The interactions of …
