Interactions Between H5N1 And The Respiratory Epithelium

Funding Amount
$623,065.00
Summary
This project examines the hypothesis that the severity of H5N1 infection is due to activation of signalling pathways in the lung not activated by human influenza and leads to fluid accumulation in the lungs death of respiratory cells. This study will improve our understanding of influenza infection and identify targets for treatment of H5N1.
Novel Analgesic Approaches: Harnessing Functional Interactions Between Sodium Channels And Opioids

Funding Amount
$329,076.00
Summary
Chronic pain is a debilitating condition that affects the life of one five Australians and has significant socioeconomic impact. Currently available pain killers often do not work, or have intolerable side effects. We have discovered that combination treatment with opioids and a novel venom-derived compound discovered by us provides effective pain relief. The aim of this project is to understand the mechanisms underlying this synergistic effect to develop new treatment approaches for pain.
Silencing Visceral Nociceptors By Targeting NaV1.1: A Novel Therapeutic Approach For Treating Irritable Bowel Syndrome

Summary
Patients with Irritable Bowel Syndrome suffer from chronic abdominal pain and co-morbidities such as over-active bladder. These symptoms arise from sensory nerve fibres in the colon and bladder that signal pain to innocuous stimuli. We are excited to report that a specific voltage-gated sodium channel, called NaV1.1, plays a key pathological role in generating these symptoms. Here, we will specifically target and block NaV1.1 expressing pain-sensing neurons, provide key advances for therapies.
The Role Of Sodium Channels In Pain And Cold Allodynia

Funding Amount
$349,306.00
Summary
Many types of chronic pain remain poorly treated and severely impact the quality of life of millions of Australians. Cold allodynia in particular, which occurs in several painful human conditions and leads to severe pain from simply touching a cool surface or item, is poorly understood and thus difficult to treat. The aim of this project is to determine the pharmacological mechanism of cold allodynia to develop novel treatment approaches.
A Pharmacological Approach To Define The Contribution Of Nav1.7 To Pain Pathways

Funding Amount
$501,467.00
Summary
Chronic pain is a debilitating condition that affects the life of one in five Australians and has significant socioeconomic impact. Currently available pain killers often do not work, or have intolerable side effects. We have discovered the most selective blocker for a specific type of sodium channel that is a known pain target and will use this novel molecule to gain insight into the mechanisms of pain and to develop new pain killers.
Physiological Function Of Nedd4-2 In Regulating The Epithelial Sodium Channel And Cystic Fibrosis Transmembrane Conductance Regulator
Funder

Funding Amount
$949,572.00
Summary
Optimal transport of sodium and chloride ions is essential for the maintenance of electrolyte balance, blood volume, blood pressure and lung function. We are studying the control of a key sodium channel (the epithelial sodium channel) and a key chloride channel (cystic fibrosis transmembrane conductance regulator) by an enzyme called Nedd4-2. This project will enable us to understand how Nedd4-2 regulates these two ion channels and to study the pathological consequences of the loss of Nedd4-2.
