Neuropeptides derived from peptidergic neurons or neurosecretory cells regulate a wide array of physiological events in vertebrates as well as in invertebrates. Functions of neuropeptides are essential for the biological rhythms, growth, olfactory perception, sensitivity to drugs, reproduction, behaviors, etc. Fruit flies (Drosophila melanogaster) are excellent invertebrate model system as diverse genetic and transgenic tools are available for this species. Using fruit flies, our lab has been studying functions of various neuropeptides and genetic bases of the development of the peptidergic neurons and regulatory mechanisms of neuropeptide gene expression. Particular interests recently are to understand the molecular genetic mechanisms as to how specific peptidergic neurons undergo apoptotic degeneration during metamorphic development. We are also interested in understanding how the peptidergic signaling is responsible for alcohol-related behavior.
