- Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg
Sammanfattning : Bilayer membranes enclose and shield the biological cell and its inner compartments, as well as the tubular networks that exist within and between the cells. Due to their fluidic nature, the membranes are incredibly dynamic and flexible, which allows them to bend, reshape and fuse in response to mechanical and chemical stimuli within their natural microenvironments.

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. Calcium signaling in neurogenesis: regulation of proliferation, differentiation and migration of neural stem cellsDetta är en avhandling från Stockholm : Karolinska Institutet, Dept of Medical Biochemistry and Biophysics
Sammanfattning : The calcium ion (Ca2+) is a highly versatile and ubiquitous signaling messenger in all cell types. Signal transduction occurs through changes in the cytosolic Ca2+ concentration after the opening of Ca2+ channels in the plasma membrane (PM) and endoplasmic reticulum (ER). LÄS MER
