1. Secondary Nucleation in Amyloid Formation
Sammanfattning : Research into Alzheimer's disease is still hampered by a lack of fundamental understanding of the underlying mechanisms. While the aggregation of the amyloid β peptide (Aβ) into amyloid fibrils is highly implicated as a key factor in the disease, the molecular nature of its involvement has proven complex and elusive.

2. Proislet Amyloid Polypeptide (proIAPP) : Impaired Processing is an Important Factor in Early Amyloidogenesis in Type 2 Diabetes
Sammanfattning : Amyloid is defined as extracellular protein aggregates with a characteristic fibrillar ultra-structure, Congo red affinity and a unique x-ray diffraction pattern. At present, 25 different human amyloid fibril proteins have been identified, and amyloid aggregation is associated with pathological manifestations such as Alzheimer’s disease, spongiform encephalopathy and type 2 diabetes.

3. The Molecular Chaperone DNAJB6 - A Suppressor of Disease Related Amyloid Fibril Formation
Sammanfattning : Several neurodegenerative diseases are caused by peptides or proteins forming amyloid fibrils such as the Aβ peptide involved in Alzheimer’s disease and the huntingtin exon-1 with a prolonged polyglutamine (polyQ) stretch involved in Huntington’s disease. The ability to form amyloid fibrils is an intrinsic feature in all proteins. LÄS MER
4. Synthesis of Ring-fused Peptidomimetics : Interacting with Amyloid Fibrils
Sammanfattning : Parkinson's and Alzheimer's disease are the two most common neurological disorders in humans. Both conditions involve progressive death of neurons in the central nervous system, decline in bodily functions and eventually (and invariably), death. So far, no cure exists and the available treatments can only ease symptoms. LÄS MER
5. Molecular mechanisms in amyloid fibril formation
Sammanfattning : This thesis concerns investigations on molecular processes and interactions that lead to amyloid fibril formation. Pulmonary surfactant protein C (SP-C), and a synthetic analogue thereof, SP-C(Leu), have similar properties in terms of charge distribution, hydrophobicity and secondary structure, yet they differ in their aggregation propensities.
