Nociceptive neurons in a fruit fly larva
Nociceptive neurons in a fruit fly larva. The entire body wall of the animal is tiled with the rectangular dendritic arbors of nociceptive neurons. In this animal, DNA encoding the jellyfish-derived red fluorescent protein TdTomato was inserted into the fly genome in such a way that it is expressed only in the nociceptive neurons. This image of a live fly larva was taken by Taylor Follansbee, B.S. '13, M.S. '15 using a confocal laser-scanning microscope.

Professor of Biology Geoffrey Ganter, Ph.D., and his research team at the ³ÉÈËÖ±²¥ published an original research paper in the top-rated Journal of Neuroscience.

Ganter’s team of ³ÉÈËÖ±²¥ undergraduate and graduate students discovered a group of components that pain-perceiving neurons use to elevate their sensitivity after injury. When the researchers blocked these components genetically, injury-triggered pain sensitization was nearly abolished. These components may therefore represent targets for novel medications for the treatment of abnormal pain, including chronic pain, in humans.

The paper’s authors include ³ÉÈËÖ±²¥ alumni and current students. The lead author of the study, Taylor Follansbee, B.S. ‘13, M.S. ’15 is now a Ph.D. student studying neuroscience at the University of California, Davis. Kayla Gjelsvik, B.S. ‘15, M.S. ‘16 is currently a research assistant at the Mount Desert Island Biological Laboratory in Salisbury Cove, Maine. Courtney Brann, B.S. ’16 is a graduate student in ³ÉÈËÖ±²¥â€™s Master’s of Biological Sciences program. Aidan McParland, B.S. ‘15, M.S. ‘16 is currently a medical student at the University of Toronto in Canada. Colin Longhurst, B.S. ’15 went on to receive a master’s degree at the University of Wisconsin, Madison where he is now a biostatistician.

The injury-induced sensitization paradigm was developed in Michael Galko’s laboratory at the University of Texas MD Anderson Cancer Center in Houston, Texas. The study was supported by a National Institutes of Health Centers of Biomedical Research Excellence grant awarded to Ian Meng, and a National Institutes of Health Academic Research Excellence Award to Ganter.
