Summary
Mycobacterium tuberculosis is the bacterium that causes tuberculosis (TB. It infects about third of all people in the world and kills several million people each year. People with active TB spread the mycobacteria in aerosols from their breath. When another person inhales an infected aerosol the mycobacteria enter their lungs and establish a new infection. During the course of infection M. tuberculosis is exposed to a variety of harsh environments inside the lungs which normally kill other bacte ....Mycobacterium tuberculosis is the bacterium that causes tuberculosis (TB. It infects about third of all people in the world and kills several million people each year. People with active TB spread the mycobacteria in aerosols from their breath. When another person inhales an infected aerosol the mycobacteria enter their lungs and establish a new infection. During the course of infection M. tuberculosis is exposed to a variety of harsh environments inside the lungs which normally kill other bacteria. M. tuberculosis is able to survive and adapt to those harsh environments. M. tuberculosis has an especially thick and tough cell wall which protects it. M. tuberculosis can adapt to the environments it encounters in a patient by changing their cell walls. The wall also protects mycobacteria from chemicals so it is resistant to many common antibiotics. There are some drugs to treat TB however M. tuberculosis is building up resistance to those drugs so we need to find new ones We will determine how mycobacteria synthesize their special cell wall and how they adapt during an infection. If we know how the details of how M. tuberculosis protects itself then we can find potential weakness which could be targets for the development of new drugs to treat TB.Read moreRead less
Functional Characterisation Of The Malaria Protein Export Machinery

Summary
The ability of malaria parasites to cause one of the most devastating infectious diseases of humans is in part due to their ability to export hundreds of proteins into their host red blood cells to obtain nutrients, evade the immune system and contribute to associated pathologies. Recently, we discovered the molecular machine that exports proteins into the host cell and so now we wish to establish how it works so that drugs can be tailored to block it to kill these parasites.
Functional Dissection Of The Malaria RhopH Complex And Its Contribution To New Permeation Pathways

Funding Amount

Summary
The ability of Plasmodium to invade and remodel its host erythrocyte are the most significant contributors to its ability to cause the disease malaria. This project aims to understand how proteins secreted from a specialized rhoptry organelle during erythrocyte invasion help Plasmodium to remodel the erythrocyte so that the parasite can gain access to the vital nutrients it requires for survival. This research will validate whether drugs targeting the rhoptry proteins are viable drug targets.

Summary
The investigators, all associated with the Melanoma Institute Australia, have recruited numerous people and biospecimens in order to study the causes, subtypes and treatment strategies in melanoma. The team aims to develop a scientific basis for improved 1) management of individuals at high risk of melanoma development and progression, and 2) treatment of patients with early and disseminated melanoma, thereby contributing to improved prospects of successfully treating this dangerous cancer.
Identification Of Genes For Non-syndromic Intellectual Disability And Walker-Warburg Syndrome

Summary
Mental retardation (MR) affects 3% of people and the cause is still largely unknown. Walker-Warburg syndrome (WWS) is an inherited cause of severe MR that also includes eye and muscle disease. Recent studies suggest that there are at least ten WWS genes. This project will identify MR and WWS genes by searching for gene alteration (mutations) that affected families have in common. Knowledge of the genetic causes will lead to better understanding of normal brain development and therapies.
Malaria is one of the worlds most significant health problems and is caused by protozoan parasites of the genus Plasmodium. We aim to understand the biology, pathogenesis, and epidemiology of P. falciparum and P. vivax infections together with a strong translational direction. Our studies will thus lead to the discovery and development of novel tools aiding in the renewed efforts for the global elimination of malaria.
