Cellular And Genetic Bases Of Cold Nociception And Nociceptive Sensitization In Drosophila Larvae, Heather N. Turner

Dissertations & Theses (Open Access)

Organisms from flies to mammals utilize thermoreceptors to detect and respond to noxious thermal stimuli. Although much is understood about noxious heat avoidance, our understanding of the basic biology of noxious cold perception is gravely minimal. Numerous clinical conditions disrupt the sensory machinery, such as in patients suffering from tissue damage (from wound or sunburn), or injury to the peripheral nerves, as in patients with diabetes or undergoing chemotherapy. Our goal is to determine the genetic basis for noxious cold perception and injury-induced nociceptive sensitization using the genetically tractable Drosophila model. Using a novel "cold probe" tool and assay we …
