1. Drosophila Sensory Neuroethology
Sammanfattning : Animals, like humans, need to perceive their surroundings via their senses in order to make sensible behavioral decisions, reproduce successfully, and survive. Animals are equipped with audition, vision, thermosensation, hygrosensation, mechanosensation, magnetoception, gustation, and olfaction, which detects physical and chemical changes in their habitats.

2. Genomic and transcriptomic investigation of reproductive incompatibility in Drosophila
Sammanfattning : Both nuclear and cytoplasmic elements can contribute to the emergence of reproductive incompatibilities that influence evolution and speciation. In the projects that compose this thesis, we use genomics and transcriptomics to study some of those elements in Drosophila. LÄS MER
3. Peptidoglycan recognition proteins in Drosophila melanogaster
Sammanfattning : The fruit fly Drosophila melanogaster is an excellent model organism to study the innate immune response, because insects and mammals share conserved features regarding the recognition and destruction of microorganisms and Drosophila is easily accessible to genetic manipulation. In my present study, I identified a new family of pattern recognition molecules for bacterial peptidoglycan in Drosophila, the Peptidoglycan Recognition Proteins (PGRP). LÄS MER
4. 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.

5. Nucleoporins and Protein Transport in Drosophila
Sammanfattning : Many biological responses rely on the selective translocation of transcriptional regulators in and out of the nucleus through nuclear pore complexes (NPC). More than one million macromolecules per minute pass through the NPC and an important challenge is to understand the coordination of nucleocytoplasmic trafficking. LÄS MER
