Characterizing The Interaction Between Human Adenovirus E1a And Sting, Jessica Hill
Characterizing The Interaction Between Human Adenovirus E1a And Sting, Jessica Hill
Electronic Thesis and Dissertation Repository
When challenged by viral DNA, the cytoplasmic DNA sensor cyclic GMP-AMP synthase (cGAS) signals through the adaptor protein stimulator of interferon genes (STING) to induce a primary type I IFN response. Studies from recent years have also revealed shared architecture between metabolism and innate immunity. Viruses have evolved to counteract these mechanisms. Human adenovirus (HAdV) early region 1A (E1A) protein antagonizes the cGAS-STING pathway to prevent an innate immune response by physically interacting with STING. I hypothesize that the interaction between E1A and STING is mediated through several motifs and involves ribosomal protein S6 kinase beta-1 (S6K1). Using a series …

Viruses confront a seemingly dichotomous relationship with their host cells. They must overcome host defenses in order to complete their infectious cycles and generate new viruses yet the host must remain healthy and hospitable for that to take place. Shortly after infection, the RIGI-like receptors (RLRs) within the cytoplasm of the infected cell recognize foreign motifs present in the pathogen. The host responds by activating a signaling pathway that leads to activation of cellular transcription factors, including the NF-κB and interferon regulatory factor 3 (IRF3), that are necessary for induction of the type 1 interferon genes. Many viruses subdue components …

Ranavirus infections are on the rise and have been implicated in numerous species die-offs across the globe. Frog virus 3 (FV3) is the type-species of the genus, yet the immune mechanisms governing susceptibility remain poorly understood. Arguably the most important immune response to infection is the type I interferon (IFN) response. Type I IFNs trigger an “antiviral state” in host cells via the production of numerous interferon-stimulated genes (ISGs) that act to inhibit virus replication in various way, including the induction of apoptosis. Apoptosis is an important antiviral defense mechanism to limit virus replication within infected cells. This study employed …
