1. Processing of the amyloid precursor protein and its paralogues amyloid precursor-like proteins 1 and 2
Sammanfattning : Alzheimer’s disease (AD) is a neurodegenerative disorder which is histopathologically characterised by amyloid plaques and neurofibrillary tangles. Amyloid plaques consist of the amyloid β-peptide (Aβ) that can form aggregates in the brain. Aβ is generated from the amyloid precursor protein (APP) through proteolytic cleavage. LÄS MER
2. In vitro modelling of tau phosphorylating kinases : emphasis of Cdk5
Sammanfattning : The main hallmarks of Alzheimer’s disease (AD) are extracellular deposits of betaamyloid (Aβ) and intracellular neurofibrillary tangles (NFT) composed of highly phosphorylated tau protein. Abnormal hyperphosphorylation of tau is the most deleterious step in NFT formation making the use of kinase inhibitors an attractive treatment possibility in AD. LÄS MER
3. SNAP-25 and Cdk5 as exocytotic regulators : consequences for synaptic function and insulin release
Sammanfattning : The process by which cells release substances through fusion of vesicles with the plasma membrane is called exocytosis. Regulated exocytosis needs to be tightly controlled in order to respond to the large variation in stimuli and demands for release of neurotransmitters, peptides and hormones. LÄS MER
4. Molecular mechanisms regulating exocytosis : studies of insulin secretion and neurotransmitter release
Sammanfattning : In order to achieve normal physiology the secretion of hormones and neurotransmitters needs to be firmly controlled. The basic molecular machinery mediating regulated exocytosis of hormones and neurotransmitters is in principal revealed, but knowledge about how the individual components are spatially and temporarily coordinated is limited.

5. Components controlling vesicle trafficking and regulated exocytosis in pancreatic beta-cells
Sammanfattning : Regulated exocytosis is a sophisticated, well-organized and conserved multistage process underlying release of both neurotransmitters and hormones. Exocytosis is mediated by SNARE proteins that act at the center stage by forming a SNARE complex with the intrinsic capability to execute membrane fusion. LÄS MER
