1. 16. The Enteric Nervous System, Plasticity and Survival

   Författare :Katarina Sandgren; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; Nitric oxide synthase; Neuropeptides; Neuronal survival; Lethal spotted mice; Interstitial cells of Cajal; Hirschsprung s disease; Cell cultures; Enteric nervous system; neuropsychology; neurophysiology; Neurologi; neuropsykologi; neurofysiologi;

   Sammanfattning : The thesis deals with plasticity in terms of neurotransmitter expression and survival of neurons in the adult enteric nervous system (ENS). Several motility disorders have been suggested to originate in developmental defects, neurodegeneration, or insufficient innervation by the ENS. LÄS MER

3. 17. Monoglyceride Lipase and Hormone-Sensitive Lipase - Molecular and structural aspects

   Författare :Marie Karlsson; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; genomic organisation; baculovirus-insect cells; catalytic triad; alfa beta hydrolase fold; tissue distribution; cDNA sequence; lipolysis; adipocyte; monoglyceride lipase; hormone-sensitive lipase; chromosomal localisation; Clinical biology; Klinisk biologi;

   Sammanfattning : Triglycerides in the adipocyte are hydrolysed by means of three consecutive reactions through the combined action of two lipases: hormone-sensitive lipase (HSL) and monoglyceride lipase (MGL). HSL catalyses the first and rate-limiting step, i.e. LÄS MER

4. 18. Metabolism of quinoline 3-carboxamide compounds, a group of synthetic immunomodulators, in various species

   Författare :Helen Tuvesson; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; enzymologi; Proteiner; enzymology; Proteins; Gastroenterologi; Gastro-enterology; pharmacokinetics; enzyme kinetics; quinoline 3-carboxamides; Keywords: Metabolism; cytochrome P450;

   Sammanfattning : Cytochrome P450 (CYP) is involved in the metabolism of the majority of clinically used drugs. We have studied the CYP mediated metabolism of quinoline 3-carboxamides, a group of synthetic immunomodulators in liver microsomal preparations from various species. LÄS MER

5. 19. Regulatory mechanisms controlling T cell activity

   Författare :Anette Sundstedt; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; transplantation; T cell superantigen anergy interleukin-2 transcription factor cytotoxicity; serology; Immunology; Immunologi; serologi;

   Sammanfattning : This thesis is based on work studying the immunoregulatory mechanisms that govern the balance between activation and inactivation of T lymphocytes. Most of the work has been carried out in an experimental system using a T cell receptor (TCR-Vb3) transgenic mouse strain to obtain a homogenous T-cell population and utilizing the properties of bacterial superantigens to induce T cell responses and unresponsiveness in vivo.

7. 20. ELUCIDATING REGULATORY NETWORKS PROMOTING B-CELL DEVELOPMENT

   Författare :Eva Welinder; Institutionen för experimentell medicinsk vetenskap; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : B-cells are an essential part of our adaptive immune system. A network of transcription factors together with external signals facilitate the gradual developmental progression from progenitor cells towards the B-cell fate. Several key factors participating in this network have been identified. LÄS MER
