Fields of Interest

Structural biochemistry/neurobiology; ultrastructural neuropathology of and adhesive mechanisms in CNS and PNS myelins; fibrillogenesis and molecular organization of amyloid assemblies; remyelination; spinal cord injury; Alzheimer's disease; prion diseases.

Academic Profile

Our current research interests are focused in two areas: the structure and dynamic membrane interactions in abnormal nerve myelin, in which alterations have resulted from experimental, pathological, or genetic conditions; and the molecular organization of amyloid, which are deposits of mis-folded polypeptides involved in certain neurodegenerative diseases (including Alzheimer's disease, Huntington's disease and prion diseases) and in systematic amyloidoses. To link structure and composition at the molecular, macromolecular and tissue levels in the nervous system, our studies in these two areas utilize x-ray diffraction, microscopy at the light and ultrastructural levels, a variety of protein and lipid biochemical techniques, and molecular modeling.

What holds myelin together, and how are its constituents targeted in diseases? To characterize the molecular organization of lipids and proteins in nerve myelin membranes, and to define the molecular interactions of its membrane arrays, we are correlating biophysical and biochemical results from different types of specimens (e.g., whole unfixed or fixed tissue from a phylogenetic range of vertebrates, tissue homogenates, tissue fractions and model lipid/protein systems). Among the questions we are addressing: how does the organization of proteins and lipids in myelin account for the inter-membrane interactions of the membranes? What is the structural basis of demyelination? Our findings are relevant to understanding the process of membrane disruption and delamination which occurs in demyelinating diseases such as multiple sclerosis and certain peripheral neuropathies. Our current focus is on understanding how specific mutations in myelin adhesion proteins or in lipid biosynthetic pathways affect the stability and functionality of the myelin.

What is the process by which proteins or their fragments self-assemble to form potentially cytotoxic amyloid deposits? The molecular organization of paired helical filaments, amyloid plaque cores and cerebrovascular amyloid isolated from Alzheimer's disease (AD) brain are being studied using a variety of structural techniques. High-resolution x-ray fiber patterns and electron microscopic images are being obtained from in vitro assemblies of synthetic polypeptides homologous with AD amyloid. Determining the dimensions and spatial organization of the structural units that comprise paired helical filaments, AD amyloids and related in vitro assemblies from prion diseases and from other amyloidoses will illuminate our understanding of their formation, interrelationships and stability, and will provide insight on how they might be related to or derive from normally occurring cellular components. These findings are also relevant to the general problem of protein folding. Current efforts are directed at developing a novel screen for assessing whether or not specific compounds can inhibit amyloid formation, and if so, by what mechanism.
