Summary
We have developed a Multiple-Antigen-Lipophilic-Adjuvant-Carrier (MALAC) system, based on the incorporation of lipoamino acids into a poly-functional core that provides an excellent means for enhancing the antigenicity of a potential peptide vaccine. A system is used for generating antibodies without the use of any conventional adjuvant. The system comprises two or more different antigens and one or more lipid anchor. The key of this system is a novel carrier construct, which is non-toxic and no ....We have developed a Multiple-Antigen-Lipophilic-Adjuvant-Carrier (MALAC) system, based on the incorporation of lipoamino acids into a poly-functional core that provides an excellent means for enhancing the antigenicity of a potential peptide vaccine. A system is used for generating antibodies without the use of any conventional adjuvant. The system comprises two or more different antigens and one or more lipid anchor. The key of this system is a novel carrier construct, which is non-toxic and non-immunogenic. The system contains variables, which allow optimising its structural configuration. A small library of poly-functional MALAC system will be synthesised in a controlled step-by-step way combining solution or solid phase techniques, where the exact chemical structure (and the order of the different immunological peptide sequences) of the construct is pre-determined. The antigenicity and the protection against disease will be compared with antigenicity and protection generated using conventional vaccine carriers. We also aim to exploit the particulate-forming properties of the lipo-peptide amphiphiles, to form micro-particulate oral antigens, exploiting the phenomenon of particulate uptake from the GI tract by the GALT or other intestinal sites. The MALAC constructs will be administered orally followed by the measurement of the serum IgG. Vaccination via the oral route is highly desirable, since it can overcome many of the disadvantages inherent in administration by injection - e.g. poor patient acceptability, requirement of skilled medical personnel, risk of HIV and other blood-born diseases, restricted availability and sometimes, stimulation of the wrong type of immunity. Development of vaccines for oral administration make them much more widely available, permitting self-administration and improving the operation of Public-Health vaccination programs, particularly in developing countries.Read moreRead less
Enabling Technologies For Design And Delivery Of Novel Vaccines Against Infectious Diseases And Cancer.
Funder
National Health and Medical Research Council
Funding Amount
$925,346.00
Summary
This grant will support research necessary to develop the next generation of vaccines. These will combat diseases caused by bacteria and viruses and can also be used to fight cancer. The broad range of application is made possible through the incorporation of simple molecular features that activate the immune system. The intellectual property that has been developed is protected by a patent portfolio some patents of which are already licenced to the pharmaceutical industry.
Dengue Fever Vaccine: Towards Low Cost Production And Delivery
Funder
National Health and Medical Research Council
Funding Amount
$612,039.00
Summary
With rising populations and a warming climate mosquito borne viral diseases will become more prevalent and low-cost vaccine production & delivery systems will become increasingly important. Here a microalgae based vaccine production platform will be coupled to proven Nanopatch & low cost oral vaccine delivery. The focus is on a Dengue virus vaccine, as Dengue causes 400 million infections & 100 million symptomatic cases annually.
Development Of A Self-adjuvanting Mucosal Vaccine Candidate Against Group A Streptococcus Using Lipid Core Technology

Funding Amount
$316,449.00
Summary
Novel developments in drug/vaccine delivery are clearly to have enormous economic and social impacts. My research aim is to rationally design and develop vaccines against relevant diseases. By understanding the mechanism of protection against diseases, development of novel vaccines for the treatment of many diseases can be achieved. This would contribute enormously to the betterment of public health.

Developing A Vaccine To Protect Against Hypervirulent Strains Of Group A Streptococcus
Funder
National Health and Medical Research Council
Funding Amount
$536,850.00
Summary
Epidemic invasive GAS disease is associated with the emergence of the globally disseminated M1T1 clone and is linked to the mutation in the CovR/S regulator. This mutation leads to over- expression of SpyCEP and inhibits recruitment of neutrophils to the site of infection. Inclusion of an immunogenic fragment of SpyCEP into our current vaccine would enhance its efficacy and lead to the development of a vaccine with a wider coverage and better protective efficacy against hypervirulent GAS strains
A Universal Prophylactic Vaccine For Hepatitis C Virus

Funding Amount
$643,337.00
Summary
Hepatitis C Virus (HCV) infects 200 million people world wide. An effective vaccine to prevent HCV is urgently needed but must afford protection against the 7 diverse genotypes. In this project grant we aim to further define the quality of the immune response that is generated by a novel HCV vaccine candidate that generates pan-genotypic immunity, its unique structural features, and methods of manufacturing so that it can be tested in a future phase I human clinical trial.
This an integrated program of basic research on antigen discovery and immune mechanisms, and preclinical research on novel vaccine platforms, formulations or delivery systems for the rational design and clinical testing of a next generation vaccine against malaria. This interdisciplinary research fosters strong national and international links and offers the potential for significant economic benefit to Australia.
