1. Studies of individual pancreatic -cells : Electrophysiological analysis of rhythmic behaviour and development of new techniques
Sammanfattning : The insulin concentration in blood varies periodically, which is believed to prevent down-regulation of the hormone receptors. Loss of the regular insulin oscillations is considered to be an early sign of developing diabetes. LÄS MER
2. The interplay of ions in the stimulation of the pancreatic -cell
Sammanfattning : Glucose stimulation of insulin release is mediated by depolarisation of the pancreatic β-cells with accompanying entry of Ca2+ through voltage-dependent channels. An important feature of the glucose-induced depolarisation is its rhythmicity causing oscillations of the cytoplasmic Ca2+ concentration ([Ca2+]i), which trigger pulsatile release of insulin. LÄS MER
3. Measurements of cytoplasmic calcium in individual endocrine cells : studies of the mechanisms of parathyroid hormone and pancreatic glucagon secretion
Sammanfattning : .... LÄS MER
4. Neuronal Cell Death and Restoration in the Basal Ganglia: Implications for Huntington's and Parkinson's diseases
Sammanfattning : Huntington's disease (HD) is a hereditary neurodegenerative disorder presenting with chorea, dementia and extensive striatal neuronal death. The mechanism through which the widely expressed mutant huntingtin mediates striatal neurotoxicity is unknown. Excitotoxicity, i.e. LÄS MER
5. The megalin receptor
Sammanfattning : Ionized calcium is a major player in the living organism. Its importance in both intra- and extracellular mechanisms have been studied in a broad number of publications. LÄS MER
