Summary
Harlequin Ichthyosis is a severe inherited skin disease caused by mutations in a protein which regulates how skin cells control their levels of lipids. Treatments for this disease are limited and do little to improve patients condition. We believe we have found a new way to treat this condition by altering tissue inflammation. This grant will undertake important experiments aimed at developing new therapies for this currently incurable disease.
Topical Drug Delivery Based On Porous Silicon Nanoneedles

Funding Amount
$318,768.00
Summary
There are currently a number of new drugs that can only be administered through the skin via hypodermic needles, which is costly, invasive and carries the risk of infection spread. This project proposes to develop an alternative strategy based on skin patches covered in millions of microscopic porous needles. These needles are able to puncture the skin painlessly to provide rapid and minimally-invasive administration of drugs for treatment of skin diseases, such as melanoma or psoriasis.
Second Trimester Intra-amniotic Treatment For Early Preterm Birth

Funding Amount
$392,420.00
Summary
Preterm birth is the leading cause of neonatal death and disability in Australia today, with those born before 32 weeks' completed gestation at the highest risk. Preventing these early preterm births requires treatment of the causative uterine infection. This proposal is to conduct the first study of direct intraamniotic antibiotic treatment of uterine Ureaplasma infection in a clinically relevant, large animal model of second trimester pregnancy.
Identification Of Factors Critical For Maintenance Of The Epidermal Barrier

Summary
The human skin plays a crucial role in the body’s defence against our hostile environment. The outer most layer of the skin, the epidermis is the key structural component of the skin barrier and is essential for its integrity. We have identified a family of genes that are pivotal for epidermal barrier formation, maintenance and repair. This project examines the mechanisms that underpin the function of this family, and has broad ramifications in a host of dermatological conditions.
Drugs are applied to the skin for the treatment of a wide range of conditions, including both local (eg. inflammation, muscle pain, eczema, psoriasis and other dermatological conditions) and systemic (eg. angina, hormone replacement, nicotine withdrawal) therapies. Advances in molecular biology technology has also led to the development of a range of large molecular weight peptide and protein based therapeutic agents for which transdermal delivery offers the most cost-effective and practical sol ....Drugs are applied to the skin for the treatment of a wide range of conditions, including both local (eg. inflammation, muscle pain, eczema, psoriasis and other dermatological conditions) and systemic (eg. angina, hormone replacement, nicotine withdrawal) therapies. Advances in molecular biology technology has also led to the development of a range of large molecular weight peptide and protein based therapeutic agents for which transdermal delivery offers the most cost-effective and practical solution if appropriate delivery systems can be identified. In addition, unwanted skin absorption also occurs following exposure to environmental occupational chemicals, and those applied deliberately to the skin such as insecticides, sunscreens and cosmetics. This study continues our work in seeking to define the relationship between the chemical structure of agents, the types of formulations and solvents in which they are applied or come into contact with the skin and their penetration, distribution and retention in the various layers of the skin and underlying tissues. Of great significance to both the pharmaceutical industry and risk assessment regulatory bodies will be the further development of our work into important areas relating to the ability to predict the likely behaviour of a solute following contact with the skin from the aspect of both optimising drug delivery systems and the accuracy of risk assessment procedures. We will also be continuing our work examining techniques to facilitate drug transport through the skin using physical techniques such as iontophoresis and the design of formulations to specifically target larger pores in the skin such as hair follicles as a means of improving delivery rates and increasing the range of solutes, particularly those of large molecular weight, likely to be considered as potential drug candidates.Read moreRead less

We intend to further our research into important areas relating to the ability to predict the likely behaviour of a solute which comes into contact with the skin from the aspect of optimising both topical drug delivery systems and risk assessment procedures. We will also be examining techniques of facilitating drug transport through the skin using (i) the knowledge gained of the mechanisms by which vehicles act on the skin, (ii) the synthesis of ester and amide lipophilic prodrugs and (iii) physical techniques such as iontophoresis, whereby small electrical currents are applied to charged drug species on the outside of the skin.Read moreRead less
