1. 1. Molecular factors influencing nerve growth : studies on the developing rodent trigeminal ganglion and tooth pulp

   Författare :Christina Lillesaar; Ted Ebendal; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : The adult tooth pulp has a rich protective sensory innervation from the trigeminal ganglion (TG). The developmental establishment of this exclusively nociceptive innervation is not fully understood today. LÄS MER

3. 2. Controlled axonal outgrowth and cell reactions to nanostructures

   Författare :Fredrik Johansson; Funktionell zoologi; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Contact guidance; neuron; axon; fibroblast; macrophage; polymethylmethacrylate; porous silicon; nanowire; magnetic; immunoresponse; nanoimprint lithography; haptotaxis;

   Sammanfattning : The interface between living cells and artificial surfaces are highly relevant for biomedical applications such as implants and organized cell growth for tissue reconstruction as well as for basic science purposes. In the present thesis, we have studied axonal guidance on various nano-patterned surfaces such as polymethyl-meth-acrylate, porous silicon and on magnetically aligned Ni nanowires. LÄS MER

4. 3. Anatomical, neurochemical and behavioural consequences of immunotoxin lesions of the basal forebrain cholinergic system

   Sammanfattning : The cholinergic hypothesis of geriatric memory dysfunction suggests that the learning and memory deficits representing the cardinal symptoms of dementia in the aged and in patients suffering from Alzheimer's disease may be attributable to a decline in the function of the cholinergic projection systems of the basal forebrain. Although many studies have addressed the issue of a causal relationship between cholinergic hypofunction and cognitive disturbance, analyses of the functional role of the basal forebrain cholinergic neuronal systems in the brain have so far been hampered by the lack of an efficient and specific cholinergic neurotoxin.

5. 4. Axon Guidance and Morphogenesis of the C. elegans Pharynx

   Författare :Manish Rauthan; Chalmers tekniska högskola; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pharynx; M2; C. elegans; extra-cellular matrix ECM ; hex; Krüppel; pha-2; isthmus; NSM; pharyngeal neurons.; cytoskeleton; mnm-2;

   Sammanfattning : The C. elegans pharynx is a single cell thick muscular tube that undergoes morphogenesis to attain it mature structure from a ball of 80 undifferentiated cells. This thesis is about understanding the mechanisms and the genetic pathways underlying the process of pharyngeogenesis. LÄS MER

7. 5. Factors influencing nerve growth in situ and in vitro

   Författare :Helena Jerregård; Mårten Risling; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Bakgranden till denna doktorsavhaodling är den problematik som uppstår efter en perifer nervskada, roreträdesvis i relation till handen eftersom den har så stor betydelse i vårt dagliga liv. En haod utan känsel fungerar dåligt och än sänne fungerar en handprotes. LÄS MER
