Summary
The world is in a need for effective vaccines for the treatment/prevention of a range of currently occurring diseases. The aim of this project is to develop sugar/lipid-based delivery systems by revolutionary new chemo-enzymatic technology. Expected outcomes of the project will be numerous biologically active vaccine candidates and novel technologies which will lead to effective therapeutic products.
Flaviviral Proteases As Viable Targets For Antiinfective Drugs

Summary
Viruses hijack the machinery and nutrients of cells they infect in order to reproduce. We will study viral enzymes (proteases) essential for virus replication, use fluorescent probes to learn where the viral enzymes hide and act in infected cells, track the passage of drugs aimed at these enzymes, design drugs to block their actions and stop virus replication, and test antiviral activity against Dengue, West Nile, Japanese Encephalitis and Yellow Fever viruses which infect millions of people.
MicroRNAs are a group of molecules that are critical for controlling the activity of genes. They function in a diverse range of biological systems, from early embryonic development to adult organs, such as the brain and immune system. Although we know that these molecules are important, there remain major gaps in our understanding of how they are produced. Thus, the goal of our research is to understand how cells make these molecules.
Metabolism-driven Interactions Of Non-typeable Haemophilus Influenzae And Its Host: A Critical Factor In Infection?

Summary
Non-typeable Haemophilus influenzae (NTHi) is the underlying cause of many severe acute and chronic respiratory infections, which represent a significant burden to the healthcare system. As NTHi is unable to survive outside the human host, it is is highly adapted to survival in the body niches it colonizes. We are investigating how NTHI is able to survive in the presence of tissue inflammation, and whether it contributes to the inflammatory process through some of its metabolic products.
Discovery And Mechanisms Of Host Cell Factors In HIV Uncoating

Funding Amount
$635,098.00
Summary
HIV entry into the host cell involves release of its capsid, a protein shell protecting the viral genome. The capsid hijacks host proteins to cloak itself from cellular defenses while the cell has evolved sensors that can block viral infection. This proposal aims to discover proteins involved in this arms race between host and virus and decipher how they control capsid disassembly. This insight will help design new drugs against HIV infection and new ways to deliver genes for gene therapies.
Protein Phosphatase 2A Methylation: Regulation And Functional Significance For Tauopathies

Summary
Clinical studies have revealed that low blood levels of the vitamin folate are a risk factor for cognitive impairment, depression and dementia, which are prevalent in the elderly. Deregulation of the protein tau is a key event in Alzheimer’s disease pathogenesis. This project will utilize cell culture and aged mouse models to determine how alterations in folate status and deregulation of protein phosphatase 2A affect the regulation of tau and other key brain processes that become altered in Alzh ....Clinical studies have revealed that low blood levels of the vitamin folate are a risk factor for cognitive impairment, depression and dementia, which are prevalent in the elderly.

Summary
The bacterium H. pylori, is the leading cause of gastric ulcers, infecting over half of the world population. Furthermore, patients infected with the bacteria exhibit an increased risk of developing gastric cancer, with 900,000 new cases diagnosed yearly. The current proposal will study an enzyme which allows the bacterium to evade the host's immune system. The work aims to develop inhibitors of the enzyme as therapeutic agents to treat peptic ulcers.
