1. Platelets : intracellular signalling and cellular interaction
Sammanfattning : Activation of platelets is essential to prevent excessive blood loss at the site of vascular injury. These highly reactive cell fragments are also involved in several pathological conditions, in particular arterial thrombosis, which, in the coronary vessels, can lead to reduced blood flow, vessel occlusion and myocardial infarction.

2. Alzheimer's disease mutations and cellular signalling
Sammanfattning : Alzheimer's disease is the most frequent cause of dementia in elderly and is characterised neuropathologically by the extracellular deposition of amyloid plaques (containing the 39-43 amino acid Abeta peptide), as well as intracellular neurofibrillary tangles (NFTs) composed primarily of an abnormally hyperphosphorylated form of the microtubule-associated protein tau. A proportion (10- 15%) of Alzheimer's disease cases is familial, the remainder being sporadic. LÄS MER
3. Cross-regulation between TGFβ/BMP Signalling and the metabolic LKB1 pathway
Sammanfattning : Cell signalling determines physiological responses to many cellular stimuli and environmental changes. The transforming growth factor-beta (TGFβ)/bone morphogenetic protein (BMP) signalling pathways begin by binding of ligand to the heterodimeric receptor complex, followed by activation of Smads that translocate to the nucleus to regulate transcription of genes that further mediate cellular physiology.

4. Injury-Induced Signalling in Arterial Smooth Muscle Cells
Sammanfattning : The vascular wall is an active, elastic and integrated organ made up of cellular and extracellular matrix (ECM) components. It is not a static organ; the components dynamically change and reorganize in response to physiological and pathological stimuli. Vascular injury induces a complex healing process, analogous to generalised wound healing. LÄS MER
5. Insulin signalling in human adipocytes : mechanisms of insulin resistance in type 2 diabetes
Sammanfattning : Prevalensen av fetma ökar drastiskt i stora delar av världen och utgör en stor riskfaktor för att utveckla insulinresistens och typ 2 diabetes. Fettväven kan bli mycket stor om för mycket energi tas upp av kroppen. LÄS MER
