1. Recognition requirements and regulatory events directing T cell responses
Abstract : The present study has considered cellular and molecular requirements in T cell responses. The central role of T cell growth factors (TCGF) in T cell responses prompted us to study the regulatory events directing TCGF production in lectin stimulated cultures. READ MORE

2. Molecular dissection of established and proposed members of the Op18/Stathmin family of tubulin binding proteins
Abstract : My initial aim was a functional analysis of the conserved Op18/stathmin family of microtubule-regulators, which includes the ubiquitous cytosolic Op18 protein and the neural membrane-attached RB3 and SCG10 proteins. The solved X-ray structure has shown that these proteins form a complex with tubulin -heterodimers via two imperfect helical repeats, which result in two head-to-tail aligned heterodimers in a tandem-tubulin complex.

3. Regulation and Function of MAP Kinases in PDGF Signaling
Abstract : Platelet-derived growth factor (PDGF) is a family of signaling molecules that stimulates cell growth, survival and migration. PDGF is recognized by specific transmembrane proteins, the PDGF receptors, which relay the signals to the cell activating the Mitogen-activated protein (MAP) kinases and other signaling pathways.

4. Regulation of tubulin heterodimer partitioning during interphase and mitosis
Abstract : The microtubule cytoskeleton, which consists of dynamic polymers of alpha/beta tubulin heterodimers, organizes the cytoplasm and is essential for chromosome segregation during mitosis. My thesis addresses the significance and potential interplay between four distinct microtubule-regulatory proteins. READ MORE

5. Cytoskeletal filament systems : assembly, regulation, and interplay in mammalian cells
Abstract : The cell represents the basic unit of structure and function for all life. The interior of a eukaryotic cell is organized by an extensive array of protein filaments – collectively referred to as the cytoskeleton. These filaments serve diverse essential functions, e.g. READ MORE
