16. BMP - a key signaling molecule in specification and morphogenesis of sensory structures
Sammanfattning : Cranial placodes are transient thickenings of the vertebrate embryonic head ectoderm that will give rise to sensory (olfactory, lens, and otic) and non-sensory (hypophyseal) components of the peripheral nervous system (PNS). In most vertebrate embryos, these four sensory placodes undergo invagination. LÄS MER
17. Tissue-Selective Activation and Toxicity of Substituted Dichlorobenzenes : Studies on the Mechanism of Cell Death in the Olfactory Mucosa
Sammanfattning : The nasal passages are constantly exposed to both air- and bloodborne foreign compounds. In particular, the olfactory mucosa is demonstrated to be susceptible to a variety of drugs and chemicals. LÄS MER
18. Modeling prediction and pattern recognition in the early visual and olfactory systems
Sammanfattning : Our senses are our mind's window to the outside world and determine how we perceive our environment.Sensory systems are complex multi-level systems that have to solve a multitude of tasks that allow us to understand our surroundings. LÄS MER
19. Activity-regulated retinoic acid signaling in olfactory sensory neurons
Sammanfattning : The aim of the studies included in the thesis is to better understand the interplay between neuronal activity-dependent gene regulation and the bioactive vitamin A metabolite all-trans-retinoic acid (RA) during postnatal development, refinement and maintenance of precise neuronal connectivity using the olfactory sensory neuron (OSN) in the olfactory epithelium (OE) of genetically modified mice as a model. We show that:Inhibition of RA receptor (RAR)-mediated transcription in OSNs reduces expression of the olfactory cyclic nucleotide-gated (CNG) ion channel, which is required for odorant receptor (OR)-mediated stimulus transduction.

20. Early development of the olfactory placode and early rostrocaudal patterning of the caudal neural tube
Sammanfattning : The development of the nervous system is a complex process. Cell divisions, cell differentiation and signalling interactions must be tightly regulated. To comprehend the mature nervous system, we have to understand its assembly during development. LÄS MER
