Summary
We will test our hypothesis that ring stabilizer (RS) compounds we invented may become future proteinuric kidney disease therapeutics. The global epidemic of kidney disease eludes present treatments. Dysfunction of podocyte cells accounts for 90% of end-stage kidney diseases. Our pilot data shows that our ring stabilizer compounds restore podocyte function in vitro and kidney function in animal models. We aim to understand their mechanism of action.
Unraveling The Molecular Mechanism Of Tau Spread In Alzheimer's Disease

Summary
Disease progression in Alzheimer's disease is still poorly understood. The project is based on new findings by the research team that suggest that core cellular pathways and building blocks of nerve cell connections are required to allow the spread of pathology in the brain. This project will establish whether these pathways can be used as effective targets to intercept disease progression and prevent further cognitive decline in Alzheimer's disease pathology.

Summary
Cell movement by the malaria parasites is fundamental to parasite infection and disease. However, whilst core components of the parasite motor driving movement are known, little is understood about their regulation, in particular actin – the dynamic force behind all parasite motility. Here by dissecting the role of actin-depolymerizing-factor-1, an essential parasite actin regulator, we hope to reveal one of the central processes that underlies motility and develop it into a potential drug targe ....Cell movement by the malaria parasites is fundamental to parasite infection and disease.

Understanding The Cause Of Muscle Weakness In Nemaline Myopathy (NM) – Moving Towards The Development Of Targeted Treatments

$408,768.00
Summary
Congenital myopathy patients have unremitting, life-long muscle weakness that severely affects their quality of life and ability to perform normal daily activities. Currently no effective therapies exist for these conditions, largely due to our limited understanding of the mechanisms leading to muscle weakness. This ECF aims to determine the cause of weakness and test two therapies which have shown promise for other conditions and can be translated into clinical use for myopathies if effective.

Summary
Malaria parasites are a leading cause of infant mortality. Despite their global impact, no vaccine exists to prevent malaria disease and resistance to current drugs is prevalent. Cell movement is an essential process for parasite development yet its potential as a drug target remains unexplored. I seek to shed light on the molecular mechanisms underlying movement, focused on the motile insect stages. Understanding gained here will support the broader goal to identify targets for transmission-blo ....Malaria parasites are a leading cause of infant mortality.

Uncover How Myosin-6 Underpins The Ca2+-dependent Recruitment Of Secretory Vesicles To The Cortical Actin Network

Summary
Neuronal communication relies on the process of exocytosis by which neurons release a neurotransmitter. Exocytosis underpins processes such as the simplest muscle movement to complex tasks such as learning and memory, and is altered in several neurodegenerative pathologies. We will investigate how the protein Myosin-6 controls exocytosis. This research will be important for understanding how neurons communicate in health and disease and will be relevant to other processes such as insulin release ....Neuronal communication relies on the process of exocytosis by which neurons release a neurotransmitter.

Summary
The proteins actin and tropomyosin form networks in cells that are involved in all of the key processes that are hijacked when a cell becomes cancerous. We discovered that the tropomyosin is the key to the function of a network and have developed drugs that target the cancer-associated tropomyosin. We will examine how the drugs kill cancer cells using a novel method, developed by us, to visualize drug activity in real time, and validate their impact on the target filaments in living tissue.
Regulation Of Actin Polymerization During Malaria Parasite Invasion Of The Human Erythrocyte

Funding Amount
$282,790.00
Summary
Malaria parasites depend on successful invasion of red blood cells for their survival. Invasion is powered by a molecular motor based on two key proteins: actin and myosin. Non-specific drugs that inhibit parasite actin block invasion, demonstrating how important its regulation is to parasite success. This project will study several newly identified malaria actin-regulators, aiming to identify new drug targets that will block malaria actin function, stop motility and as such prevent disease.
