Summary
Pain changes the way we move. Although undisputed, there is a surprising lack of agreement regarding the underlying mechanisms. This project involves an innovative mix of neurophysiological methods to investigate how the drive to muscle cells from the nervous system is altered during pain. We aim to resolve the perplexing problem of how pain changes our ability to activate muscle. Our findings are likely to provide a clear understanding of the underlying mechanisms and guide rehabilitation.
Can Persistent Bladder Pain Be Treated By Targeting TRPA1 Expressing Nociceptors?

Summary
Persistent visceral pain is extremely difficult to treat and manage. To solve this problem we need to understand how pain nerves in internal organs differ from those in skin and muscle. We have discovered a pain-detecting molecule TRPA1 in bladder sensory nerves. We aim to show how bladder inflammation changes the function of these bladder pain detectors and test a new way of selectively anesthetising them. We also will use a new technique to study how the bladder lining detects pain.
Mechanism And Treatment Of Sympathetically Maintained Pain

Summary
This project investigates a crucial but neglected element in the mechanism of chronic pain that develops after nerve and tissue injury. In particular, our aim is to establish whether expression of a chemical target of the neurotransmitter noradrenaline increases in the painful skin of affected patients, and whether medication that blocks this target alleviates inflammation and pain. If so, this may open up new avenues for treatment for previously intractable pain syndromes.
Involvement Of Adrenergic Receptors In Neuropathic Pain

Summary
After nerve or tissue injury including burns, some people will suffer from a condition called neuropathic pain. This is a condition where chronic pain is endured, often totally unrelated to the initial injury or induced by events that would normally not be painful. Our project will determine whether this abnormal pain response is due to an abnormal communication between the nerves that carry pain signals (sensory nerves) and nerves that form part of the sympathetic nervous system, which is part ....After nerve or tissue injury including burns, some people will suffer from a condition called neuropathic pain. This is a condition where chronic pain is endured, often totally unrelated to the initial injury or induced by events that would normally not be painful. Our project will determine whether this abnormal pain response is due to an abnormal communication between the nerves that carry pain signals (sensory nerves) and nerves that form part of the sympathetic nervous system, which is part of autonomic (or involuntary) nervous system. We believe that this abnormal communication is due to an increase in the expression of special receptors called adrenergic receptors, on the sensory nerves. Our project will look at these receptors in the skin of animals that have had pain conditions induced, and also in skin samples from patients who suffer from neuropathic pain that can be classified as sensitive to sympathetic stimulation. By better understanding how neuropathic pain is derived, we can open the door to novel treatment approaches in these difficult to treat conditions.Read moreRead less
What drives the pain associated with inflammation is unknown as is the relationship between pain and the extent of tissue damage associated with disease, for example, arthritis. Our laboratory has shown that a particular protein is a key mediator of inflammatory pain. The project is to understand how this particular protein promotes pain, including how it sensitzes neurons.
I am a neuroscientist who is fascinated by the ways in which peripheral and spinal neurons respond to environmental changes. By understanding these responses, I hope to develop new ways to treat neural conditions caused by injury, endocrine disturbances and inflammation.
Bile Acid And Neurosteroid Signaling To The Nervous System

Summary
Defects in the secretion of bile into the intestine cause digestive diseases, and abnormal circulating levels of bile acids induce profound itch and abnormal pain sensation. This project examines whether a cell-surface receptor (TGR5) produced by intestinal and sensory neurons mediates actions of bile acids on intestinal functions, itch and pain. The project will define mechanisms of digestive and sensory disorders and identify new therapies for constipation, diarrhoea, itch and pain.
The Effects Of Tonic Muscle Pain On The Sympathetic And Somatic Motor Systems In Human Subjects

Funding Amount
$462,948.00
Summary
The main objective of this proposal is to reveal the effects of nociceptive reflexes in humans, and thus identify their functional and clinical implications. By performing invasive recordings from the nerves that control blood vessels and muscles in healthy volunteers subjected to long-lasting (~1 hour) experimental pain, this work will increase our understanding of the adaptive changes that pain induces and improve treatments to prevent pain from becoming chronic.
