1. Cloning, Expression, Pharmacological Characterization and Anatomical Distribution of Melanocortin Receptors in an Evolutionary Perspective
Sammanfattning : The melanocortin (MC) receptors are G-protein coupled receptors thatparticipate in several important physiological functions such as the regulation of the energy balance. This thesis focuses on the evolutionary aspect of the MC receptors and their pharmacology.One MC4 receptor and two MC5 receptor subtypes were found in a teleost fish, zebrafish. LÄS MER
2. Neurotrophic Factor Receptors in the Normal and Injured Visual System : Focus on Retinal Ganglion Cells
Sammanfattning : The focus of this thesis is the life and death of adult retinal ganglion cells (RGCs). RGCs are neurons that convey visual information from the retina to higher centers in the brain. LÄS MER
3. Brain Stem Involvement in Immune and Aversive Challenge
Sammanfattning : Activation of the immune system by e.g. bacteria induces the acute-phase-response and sickness behaviour. The latter encompasses among other things fever, lethargy, anorexia and hyperalgesia. LÄS MER
4. Gene Expression in the Brains of Two Lines of Chicken Divergently Selected for High and Low Body Weight
Sammanfattning : Artificial divergent selection of chickens for high and low body weight at 8 weeks of age has produced two lines: the high (HWS) and low (LWS) body weight chicken lines. In addition to the difference in body weight, the lines show extreme differences in feeding behaviour and body composition. LÄS MER
5. The Role of the Melanocortin System in Linking Energy Homeostasis with Reward Mechanisms
Sammanfattning : There is evidence of a link between peripheral signals of energy homeostasis and reward mechanisms. A hypothesis was formulated that the melanocortin (MC) system is part of this link. The hypothesis was tested by a series of receptor expression and neurochemical studies in rats. LÄS MER
