1. Phosphoinositides control insulin secretion through multiple routes
Abstract : Glucose-stimulated insulin secretion from pancreatic beta cells is the sequence of events that starts with glucose uptake and ends with the fusion of insulin granules with the plasma membrane through Ca2+-triggered exocytosis. Phosphoinositides are minor components of all cellular membranes, yet play fundamental roles as regulators of many cellular processes. READ MORE

2. Functional characterization of the secretory pathway and the role of COPI vesicles
Abstract : In the secretory pathway, proteins synthesized in the endoplasmatic reticulum move through the Golgi apparatus in a cis-to-trans direction and then sorts into different types of vesicles at the trans-Golgi network. How intracellular transport takes place has been the focus of cell biology research for a long time. READ MORE

3. Membrane lipids and their transfer proteins in β-cells
Abstract : Insulin secretion from β-cells is essential for glucose homeostasis and is often dysregulated in diabetes. Intracellular Ca2+ and membrane lipids cooperate to control insulin secretion with high spatial and temporal precision. READ MORE

4. Studies on 15-lipoxygenase in dendritic cells and leukotriene receptors in Hodgkin lymphoma
Abstract : Classical Hodgkin lymphoma (cHL) is histologically characterized by a minority of malignant cells, the so-called Hodgkin-Reed Sternberg (H-RS) cells, surrounded by inflammatory cells such as T lymphocytes, eosinophils, macrophages and mast cells. It is generally believed that various molecules released by the H-RS cells are of major importance in the pathophysiology of cHL. READ MORE

5. Plant Phosphoinositide Kinases. A Study of PtdIns 4-kinases and a PtdIns 4-phosphate 5-kinase
Abstract : Phosphoinositides are of particular interest in signal transduction processes as they can be sequentially phosphorylated and used as precursors for the intracellular messengers inositol trisphosphate (InsP3) and diacylglycerol (DAG) that in turn affects calcium levels and protein kinase cascades, eventually leading to a physiological response. The activity and regulation of PtdIns 4-kinases and PtdInsP kinase was studied. READ MORE
