1. Structural investigation of SOD1 aggregates in ALS : identification of prion strains using anti-peptide antibodies
Sammanfattning : Amyotrophic Lateral Sclerosis (ALS) is a fatal neurodegenerative syndrome characterized by progressive degeneration of motor neurons that result in muscle wasting. The symptoms advance gradually to paralysis and eventually death. Most patients suffer from sporadic ALS (sALS) but 10% report a familial predisposition. LÄS MER
2. Prion-infection and Cellular Signaling : Influence of scrapie-infection on lipid raft-associated proteins
Sammanfattning : Prion diseases are a group of fatal neurodegenerative diseases affecting almost all mammals including humans. The diseases are caused by formation of the misfolded isoform of the cellular prion protein (PrPC) to the disease causing PrPSc. LÄS MER
Sammanfattning : In this thesis, the biochemical mechanisms for complement activation by endogenous proteins are explored. The short leucine-rich repeat proteins (SLRPs) help organise extracellular matrices. We found that several SLRPs bind C1q and of these, fibromodulin and osteoadherin trigger complement. LÄS MER
Sammanfattning : Amyotrophic lateral sclerosis (ALS) is an adult-onset fatal neurodegenerative disease characterized by a progressive degeneration of the upper and lower motor neurons. The resulting paresis begins focally, usually in one muscle, and spreads contiguously, leading to muscle wasting, progressive paralysis and eventually death. LÄS MER
Sammanfattning : By varying its secondary or tertiary structure a single protein can attain new biological functions. The amyloid forming proteins are the best known examples where a change in conformation leads to the formation of amyloid fibrils that accumulate in tissues and cause disease. LÄS MER
