6. Pathogen entry mechanisms and endocytic responses to plasma membrane damage
Sammanfattning : Endocytosis is a fundamental cellular process by which cells transport material from the outside to the inside of the cell through the formation of membrane invaginations that bud off from the plasma membrane. This process is important for nutrient uptake, regulating cell surface receptors and the overall plasma membrane composition. LÄS MER
7. Exploring Cellular Dynamics : From Vesicle Tethering to Cell Migration
Sammanfattning : Cells in the body communicate with each other in order to cooperate efficiently. This communication is in part achieved by regulated secretion of signaling molecules, which when released from a cell may activate receptors present at the plasma membrane of an adjacent cell. Such signals affect both cell fate and behavior. LÄS MER
8. In vitro Studies of β-cell Death and Survival. Modulation by Adenoviral Vectors and Bcl-2 Overexpression
Sammanfattning : Type 1 diabetes is a multifactorial disease resulting from the selective destruction of insulin-producing β-cells within the pancreatic islets of Langerhans. The mechanisms of β-cell death are not fully understood but cytokines are important mediators of this process. LÄS MER
9. Cellular Dyes and Bioactive Peptides - Cell Membrane Interactions and Cellular Uptake
Sammanfattning : Knowledge about mechanisms behind interactions of molecules with biomembranes and cellular uptake is very important for understanding biological processes and for drug design. The work described in this thesis has focused on interactions of cellular dyes and bioactive peptides with cells and the cell membrane. LÄS MER
10. Plasma membrane order; the role of cholesterol and links to actin filaments
Sammanfattning : The connection between T cell activation, plasma membrane order and actin filament dynamics was the main focus of this study. Laurdan and di-4-ANEPPDHQ, membrane order sensing probes, were shown to report only on lipid packing rather than being influenced by the presence of membrane-inserted peptides justifying their use in membrane order studies.
