1. Gene expression in the dorsal root ganglion and the role of PAI-1 and amphiregulin during regeneration
Sammanfattning : This thesis is concerned with two aspects of peripheral nerve injury. First the early changes in the gene expression of the dorsal root ganglion (DRG) in response to sciatic nerve injury as revealed by micro-array analysis. Second an examination of the effect of PAI-1 and amphiregulin on survival and axonal outgrowth from DRG. LÄS MER
2. Effects of nucleus pulposus on nerve root circulation and function. Morphologic and functional studies in an experimental model using porcine spinal nerve roots
Sammanfattning : Sciatica due to lumbar disc herniation has for many decades been viewed as a consequence of mechanical compression exerted on spinal nerve roots by the bulging disc tissues. Recent research has, however, indicated that extruded nucleus pulposus (NP) from the intervertebral disc might cause functional and endoneurial morphological changes in spinal nerve roots, without mechanical compression.

3. Studies on Peripheral Nerve Regeneration: Microdispensing, Neurite Guidance and Galectins
Sammanfattning : The present thesis describes development of a microdispenser-based technique to create of protein patterns for neurite guidance. The same technique was also developed to allow direct positioning of dissociated cells, including neurons, on cell culture substrates. Finally the role of galectin-3 and 8 during nerve regeneration was investigated. LÄS MER
4. Regeneration of Peripheral Nerves. The role of protein kinases, with emphasis on neurotrophic factor stimulation
Sammanfattning : The purpose of this study was to investigate the role of protein kinases in peripheral nerve regeneration, with the use of dorsal root ganglia (DRG) and nodose ganglia explants from adult mice. The effects of neurotrophic factor stimulation and protein kinase inhibition were studied for long (days) and short term (minutes) effects. LÄS MER
5. Anti-Apoptotic Proteins in Nerve Cell Survival and Neurodegeneration
Sammanfattning : Apoptosis is a genetically regulated cell death program, which shows distinct morphological characteristics. It takes place during neuronal development and in some neurodegenerative diseases. During apoptosis, the intracellular proteins are degraded by various caspases, cysteine aspartases, which are regulated by pro- and anti-apoptotic signals. LÄS MER
