Trigeminal pain includes such disorders as headache, migraine, trigeminal neuralgia, dental and temporomandibular joint pain. These disorders affect more than 10 % of the population and many of the afflicted get only partial relief from current treatments. Trigeminal pain is conveyed from the head to the brain via primary afferent nerves. Work in the current proposal focuses on transmission of information in the brainstem as well as in the primary afferent nerves.

These disorders affect more than 10 % of the population and many of the afflicted get only partial relief from current treatments. Trigeminal pain is conveyed from the head to the brain via primary afferent nerves. Work in the current proposal focuses on transmission of information in the brainstem as well as in the primary afferent nerves. Previously our group has reported that adenosine- 5' triphosphate (ATP) causes an increase in excitatory neurotransmission from primary afferent nerves; such an increase has been reported to be painful in previous human and animal studies. Recently we have shown that the ATP induced increase in neurotransmission is dependant on activation of a specific excitatory receptor, the N-methyl D aspartate (NMDA) receptor, which has been widely implicated in other brain functions such as memory, and in disorders such as neuron death following stroke. The chief investigators involved in this application plan to study the role of the ATP receptor and the interaction with NMDA receptors in an inflammatory trigeminal pain model. Electrophysiological, pharmacological and immunohistochemical studies will be performed in order to address the aims of this proposal. A greater understanding of how these receptors modulate neurotransmission in pain pathways will lead to a greater understanding of trigeminal pain and the potential development of new therapeutics.Read moreRead less
Acute injury can lead to chronic immune activation in both chronic kidney disease and in transplantation. We will study the role of a class of molecules, the purines, that are released by injury and lead to immune activation. We will focus on the molecular variations and pharmacological blockade of their receptors as potential treatments for kidney disease and transplant graft failure.

Summary
Saliva "lacks the drama of blood, the sincerity of sweat & the emotional appeal of tears". But spit has important roles for the mouth & digestion. Now researchers in Brisbane have found baby dribble has natural chemicals that form ‘nucleotides’ in cells. They are testing the theory that the nucleotides encourage friendly bacteria in the mouth & gut. When baby saliva mixes with breast milk it also makes natural antibiotics called 'oxidative radicals' that stop bad bacteria. This may be part of th ....Saliva "lacks the drama of blood, the sincerity of sweat & the emotional appeal of tears". But spit has important roles for the mouth & digestion.
