6. The function of annexin I in human neutrophils. Studies of membrane binding
Abstract : The neutrophil granulocyte plays an important role in host defense against infections induced by invading microorganisms. The defense mechanism is dependent on the migration of neutrophils from the blood stream to the infected area, where the intruder is phagocytosed and killed. READ MORE

7. Exploring Cellular Dynamics : From Vesicle Tethering to Cell Migration
Abstract : 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. READ MORE

8. Plasma membrane order; the role of cholesterol and links to actin filaments
Abstract : 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.

9. Signal transduction in macrophages. Intracellular pathways activated by microbial constituents
Abstract : Macrophages play an essential role in the defense against infection by phagocytosis and by production of inflammatory mediators. Such mediators are TNF? and eicosanoids. Many microbial agents elicit arachidonate release in macrophages that lead to the formation of eicosanoids. READ MORE

10. Membrane rafts and its GPI anchored complement inhibitors regulate insulin secretion
Abstract : Type 2 diabetic patients usually exhibit an abnormal lipid profile. One such lipid that is constantly elevated in T2D is cholesterol. At the cellular level, cholesterol aids in tight packing of sphingolipids in certain regions of the plasma membrane and these specialized regions are termed ‘membrane rafts’, which act as signalling hubs.
