1. Assessment of eosinophil degranulation in allergic diseases and experimental models
Sammanfattning : In allergic disorders, the eosinophilic granulocytes migrate to affected tissues and release granule proteins with cytotoxic, immunoregulatory, and remodeling-promoting properties. Given that degranulation is reflected by a loss in eosinophil granule density of living cells, or by cell membrane rupture and release of intact granules, these morphological changes may represent a biomarker of the allergic disease.

2. Studies on intrinsic and extrinsic sources of variability in pharmacokinetics and pharmacodynamics
Sammanfattning : Variability in pharmacokinetic and pharmacodynamic parameters between individuals can be due to intrinsic and extrinsic factors. In this thesis three different areas regarding sources of variability have been investigated. 1. Formulation properties as an extrinsic source of variability. LÄS MER
3. Domain swapping as a molecular mechanism in amyloidosis
Sammanfattning : Amyloidosis is a group of diseases characterized by a change in protein conformation resulting in aggregation and tissue deposition of amyloid fibrils. One variant of cystatin C, L68Q cystatin C, is highly amyloidogenic and persons carrying the corresponding gene suffer from massive cerebral amyloidosis leading to brain hemorrhage and death. LÄS MER
4. Beta-amyloid, tau-protein and cystatin C in the pathophysiology of Alzheimer´s disease
Sammanfattning : Alzheimer´s Disease (AD) is a progressive neurodegenerative dementia characterized by the extracellular accumulation of the beta-amyloid (Ab) peptide into plaques and intracellular phosphorylation and accumulation of tau protein into neurofibrillary tangles (NFT). Inflammation due to astrocytic and microglial activation is one of the ongoing processes in the disease giving rise to cytokine production and oxidative stress. LÄS MER
5. Cystatin C functions in vitro and in vivo. Studies on target enzyme inhibition by cystatin C variants and cystatin C deficient mice
Sammanfattning : Cystatin C variants with Arg8, Leu9 and/or Val10 replaced by Gly residues were produced by site-directed mutagenesis and E. coli expression. LÄS MER
