Complement Inhibitors For Treatment Of Chronic Inflammatory Diseases

Funding Amount
$623,606.00
Summary
We aim to provide new therapeutic approaches to gum disease, which not only causes tooth loss, but also contributes to other diseases, such as cardiovascular disease and diabetes. We will find new methods to inhibit a system in our own bodies that contributes to inflammation and gum disease and test the effects of these methods of inhibition in disease models. In this way, we hope to lessen the burden of gum disease on the Australian population.
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.
Disruption Of Proteolytic Cascades In The Skin:towards Halting The Atopic March

Summary
There are over 3000 named skin disorders which range in severity from the trivial including acne, to life threatening such as skin cancer. Many skin diseases result from a lack of control over the way the skin maintains itself. Cutting the connections that hold cells together is key to balancing loss of skin cells with their continuous replacement. This project focuses on making compounds to block skin cell shedding with the longer term aim of producing novel drugs to treat skin disease.
Scabies Mite Intestinal Proteases As Targets For Novel Therapeutics.

Funding Amount
$672,533.00
Summary
Scabies causes bacterial disease affecting poor people worldwide. Available therapies are limited and drug resistance is emerging. We investigate molecules that the mite needs to infest the skin, to guide the formulation and the testing of novel drugs. This will provide improved treatment of affected individuals and their families, thereby reducing the spread of scabies and bacterial infections and their devastating sequelae, particularly in Australian Indigenous communities.
Downsizing A Human Protein To Modulate Inflammatory Diseases

Funding Amount
$516,793.00
Summary
We have discovered how to downsize a human protein to very small molecules with the same activities and potencies. Small changes enable the compounds to powerfully block the actions of the protein. These small molecules are very stable in blood, whereas the protein deactivates in minutes. This project will develop the small molecules into experimental drugs and test them in human cells and proteins, and in rats to evaluate their potential for treating human inflammatory diseases.
Capturing New Drugs That Selectively Modulate PAR2 Signaling Pathways

Summary
Infection and tissue damage provoke acute inflammatory responses that sometimes continue unchecked, leading to different kinds of debilitating inflammatory diseases and cancers. We have discovered a new class of drugs that bind to a new target on human cells and block undesirable prolonged inflammatory responses. This project tests a new strategy to produce 'cleaner' drugs that act more selectively with fewer side effects against a new target in the treatment of arthritis and other inflammatory ....Infection and tissue damage provoke acute inflammatory responses that sometimes continue unchecked, leading to different kinds of debilitating inflammatory diseases and cancers. We have discovered a new class of drugs that bind to a new target on human cells and block undesirable prolonged inflammatory responses. This project tests a new strategy to produce 'cleaner' drugs that act more selectively with fewer side effects against a new target in the treatment of arthritis and other inflammatory diseases, diet-induced obesity and cancers.Read moreRead less
This proposal aims to examine how the oral bacterial pathogen, P.gingivalis, interacts with the host to worsen the severity of disease in rheumatoid arthritis. We propose a new mechanism whereby the pathogen directly activates a major destructive host pathway to promote tissue and bone destruction, which are two of the clinical hallmarks of rheumatoid arthritis. We also propose that this host-pathogen interaction occurs in periodontal disease.
Plasmin is a complex enzyme that performs major roles in removal of blood clots, wound healing and in tumor metastasis. Here we will understand how plasmin function is regulated at the molecular level. These key insights will be of future use in the development of therapeutics targeting the plasmin system in cancer and clotting diseases.

Summary
We will investigate malaria, a parasitic disease that kills over 450,000 people a year. We will explore how the parasite identifies, invades and remodels the host cells in which it lives, scavenging nutrients and hiding from the immune system. We will characterize the proteins involved in these critical events, as they are potential targets for drugs. We will study how parasites cause disease and how the host responds to infection.
