1. Peptide and GABA regulation of Peptide Hormone Release in the Drosophila Brain
Sammanfattning : .... LÄS MER
2. 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.

3. Morphological and functional effects of insulin signaling and the bHLH transcription factor Dimmed on different neuron types in Drosophila
Sammanfattning : In Drosophila, the insulin signaling pathway is at the interface between dietary conditions and control of growth and development, reproduction, stress responses and life span. Eight insulin like peptides (Dilp1-8), an insulin tyrosine kinase receptor (dInR) and its downstream components, as well as a relaxin-like receptor type (Lgr3) form the core of this signaling.

4. Neuropeptides and GABA in control of insulin producing cells in Drosophila
Sammanfattning : Insulin plays an important role in metabolic regulation as well as in growth, fecundity and stress resistance. In order to understand more about the regulation of insulin-like peptide (DILP) production and release we investigate the impact of neuropeptide (DTK) signaling and classical neurotransmitter (GABA) signaling onto the insulin producing cells of the Drosophila brain.

5. 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.
