1. Tachykinin-related peptide signaling and its role in metabolic stress in Drosophila
Sammanfattning : Tachykinins (TKs) constitute a highly conserved family of multifunctional neuropeptides that are known to be involved in a multitude of functions in mammals. Peptides that are presumed ancestrally related to tachykinins, so called Tachykinin-related peptides (TKRP) have been identified in invertebrates. LÄS MER
2. Chemical signalling in the Drosophila brain : GABA, short neuropeptide F and their receptors
Sammanfattning : Gamma-aminobutyric acid (GABA) and short neuropeptide F (sNPF) are widespread signalling molecules in the brain of insects. In order to understand more about the signalling and to some extent start to unravel the functional roles of these two substances, this study has examined the locations of the transmitters and their receptors in the brain of the fruit fly Drosophila melanogaster using immunocytochemistry in combination with Gal4/UAS technique.

3. Multiple neurotransmitter inputs modulate circadian clock neurons in Drosophila
Sammanfattning : Most animals have endogenous circadian clocks, which drive daily rhythms in behavior and physiology to adapt to daily cycles of the environment. Several sets of neurons have been identified as circadian pacemakers (clocks) in the brain of Drosophila melanogaster, but the neuronal circuits and neurotransmitters signalling circadian information are poorly known.

5. Regulation of insulin producing cells, stress responses and metabolism in Drosophila
Sammanfattning : In Drosophila, neuropeptides have regulatory roles in development, growth, metabolism and reproduction. This study focused on GABA and the neuropeptides Drosophila tachykinin (DTK), short neuropeptide F (sNPF), adipokinetic hormone (AKH), corazonin (CRZ) and Drosophila insulin-like peptides (DILPs) as possible regulators of metabolic stress responses and homeostasis.
