21. Human antibody repertoires in normal physiology and in autoimmune disease
Sammanfattning : The immune system has to balance the need for a broad protection from infectious agents against the risk of developing autoimmune disease. The elements of the immune system should provide clues about conditions under which physiological autoreactivity may develop into autoaggressive immunity, if analyzed against the background of the immune system in healthy individuals.

22. Neuroprotection and neurogenesis after experimental stroke
Sammanfattning : In this thesis, two potential endogenous mechanisms for neuronal survival and repair have been investigated in a rat model of stroke, middle cerebral artery occlusion (MCAO): signaling of the GDNF family of neurotrophic factors, and neurogenesis from endogenous progenitor cells. As determined by in situ hybridization for GDNF family ligand and receptor genes, MCAO caused widespread upregulation of both components of the functional GDNF receptor, c-Ret and GFRalpha1, indicating that GDNF may be a survival signal in stroke.

23. Primary osteoarthrosis in guinea pigs
Sammanfattning : The course of primary osteoarthrosis (OA) in Hartley guinea pigs, which spontaneously develop OA in their knee joints, was studied by stereology (quantitative morphology). Between 6 and 12 months of age, structural changes similar to those of human OA developed, predominantly in the central (non-meniscus-covered) medial condyle, while the lateral condyle remained unaffected.

24. Detection and Sequencing of Amplified Single Molecules
Sammanfattning : Improved analytical methods provide new opportunities for both biological research and medical applications. This thesis describes several novel molecular techniques for nucleic acid and protein analysis based on detection or sequencing of amplified single molecules (ASMs). LÄS MER
25. Human Beta-microseminoprotein expression, with special reference to gastric mucosa, atrophic corpus gastritis and gastric carcinoids
Sammanfattning : Human Beta-microseminoprotein is a 94 amino acid protein with 10 cysteins present in seminal plasma and on many mucosal surfaces in the body. The function of the protein is unknown. The purpose of this investigation was to study the distribution of Beta-microseminoprotein in the human body, especially in the stomach. LÄS MER
