Initial Interactions Of Herpes Simplex Virus With Innate Immune Cells In Human Skin

National Health and Medical Research Council
Funding Amount
$522,589.00
Summary
Herpes simplex viruses 1 and 2 cause widespread and occasionally serious diseases including genital herpes, neonatal death and encephalitis. Current vaccine candidates are at best partially effective. This grant will examine the way that the virus enters, initially spreads within the skin and interacts with immune cells to help determine which cells should be stimulated by vaccines.
Glycotherapeutics; A New Class Of Treatment For Alphavirus-induced Musculoskeletal Disease

Funding Amount
$449,868.00
Summary
The hallmark of alphavirus disease is crippling pain and joint arthritis, which often has an extended duration. Currently there is no licenced specific treatment for alphavirus disease and the increasing spread of infection highlights an urgent need for therapeutic intervention strategies. This grant looks at the potential of pentosan polysulfate as a promising drug-repurposing candidate for the treatment of alphavirus-induced arthritis.
Elucidation Of Immune Mechanisms Underlying HSV Vaccine Development

Funding Amount
$573,993.00
Summary
HSV-1 and -2 causes genital herpes, cold sores, encephalitis, potential fatal neonatal herpes, keratitis and blindness as well as severe disease in transplant patients. HSV infection also enhances the acquisition of HIV by 2-3 fold. Investigating the mechanism of immune response to HSV infection or components of HSV will assist in understanding immune control of HSV, HSV vaccine development, and assist in reducing in HIV spread.
HIV Assembly, Transport, Egress And Transfer From Infected Dendritic Cells

Summary
HIV-AIDS is the fourth leading killing disease worldwide, with the disease burden shifting towards women. Study of the HIV life cycle in cells known to be targetted during HIV transmission is key towards designing additional preventative measures in the form of topical gels known as microbicides. Mapping of the basic pathways of viral transport within such cells, will aid further drug discovery and-or appropriateness of use of existing drugs in microbicide formulations.
Defining The Interaction Of HIV With The Interferon System In Initial Mucosal Infection

National Health and Medical Research Council
Funding Amount
$867,716.00
Summary
Very early after virus exposure, immune cells secrete interferons that help limit the spread of viruses within the body. We will investigate the complex interplay between HIV and the interferon system, especially how HIV inhibits the early induction of interferon to aid its spread and then how the body later restores the interferon response. We will also examine how HIV manipulates the interferon system in order to persistent latent reservoirs within tissues.
Cell Type Specific Biologic Responses To HIV Infection

Funding Amount
$636,242.00
Summary
The way in which HIV alters the internal environment of its target cells to facilitate its growth will be examined. These changes enhance its ability to gain a toehold in the human body after entering the genital tract and its persistence for life in the brain and elsewhere in the body.
Degradation of atomically dispersed M-N-C carbon catalysts in acidic media. This project aims to provide a clear understanding of the degradation mechanisms of transition metal (M) and nitrogen (N) co-doped carbon (M-N-C) catalysts in acidic media by utilising new model catalysts, standardised degradation tests, comprehensive catalyst characterisation, and machine learning tools to interrogate mechanistic hypotheses and link degradation mechanisms to specific catalyst characteristics. This proje ....Degradation of atomically dispersed M-N-C carbon catalysts in acidic media. This project aims to provide a clear understanding of the degradation mechanisms of transition metal (M) and nitrogen (N) co-doped carbon (M-N-C) catalysts in acidic media by utilising new model catalysts, standardised degradation tests, comprehensive catalyst characterisation, and machine learning tools to interrogate mechanistic hypotheses and link degradation mechanisms to specific catalyst characteristics. This project expects to generate new knowledge on rationally designing robust hydrogen fuel cell catalysts. This will provide significant benefits, such as new knowledge on catalyst degradation, new catalysts for energy conversion applications, and collaborations with the industry to accelerate Australia’s shift to renewable energy.Read moreRead less
Pathogenesis Of Persistent Human Virus Infections Of Global Significance

Summary
The study will investigate why humans cannot eradicate particular viruses (HIV-AIDS, cytomegalovirus and herpes simplex virus), the long term effects of these viruses and ways to improve control. Current treatments can only partly suppress the levels of these viruses, because they persist in certain parts of the body called reservoirs, only to resurge later causing disease. Thus, the overall aim of the research program is to discover the mechanisms by which these viruses are able to successfully ....The study will investigate why humans cannot eradicate particular viruses (HIV-AIDS, cytomegalovirus and herpes simplex virus), the long term effects of these viruses and ways to improve control. Current treatments can only partly suppress the levels of these viruses, because they persist in certain parts of the body called reservoirs, only to resurge later causing disease. Thus, the overall aim of the research program is to discover the mechanisms by which these viruses are able to successfully persist within reservoirs in the human body. The research program brings together a group of 6 leading scientists and clinicians located at 3 sites in 2 Australian cities. The team is comprised of experts in the study of HIV-AIDS, cytomegalovirus and herpes simplex virus who will combine their knowledge and expertise to speed up the process of research on these viruses that are of major health importance. Studies will also utilise a number of cutting edge technologies that now make it possible to much more rapidly and precisely determine how viruses cause disease. Advances in our understanding of how viruses persist may form the basis for treatments aimed at controlling persistent infections and the serious diseases caused by these viruses.Read moreRead less
HIV-1 Transcriptional Gene Silencing By Promoter Targeted Si/shRNAs: Uncovering Mechanisms, Optimising Delivery Systems, Assessing In Vivo Efficacy.

Summary
Current therapy for HIV is effective but must be taken for life. If therapy is stopped the virus comes back immediately from reservoirs not affected by current drugs. These fluctuating levels of virus are associated with increased illness and death. We are exploring a method of inducing prolonged viral latency using short double stranded RNA molecules. We propose to understand the mechanism of action of these possible therapeutics and to develop these constructs towards use in clinical trials.
