Download or read book Studies of Protein-protein Interactions at Membrane Interfaces Using Correlated Atomic Force and Fluorescence Microscopy written by James Eric Shaw and published by . This book was released on 2007 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Processes occurring at membrane interfaces are important for cellular and biological functions. The inability to readily crystallize membrane proteins for X-ray diffraction, or in solution NMR to study proteins with large molecular weight and to retain all intramolecular structures of the membrane proteins during their solubilisation process by detergents are the key reasons for a scarcity of atomic-resolution membrane protein structures. This has hindered our understanding of the structure-function relationship of membrane proteins. New strategies for studying membrane proteins will provide more insights. In this thesis, we have coupled atomic force microscopy and two fluorescence microscopy techniques---total internal reflectance fluorescence microscopy and confocal laser scanning microscopy, to visualize protein-membrane interactions and dynamics in model membrane systems. To validate our correlated approach, we investigated the partitioning of various lipid fluorescent probes in phase-separated supported planar bilayers. We applied the same methodology in two case studies of peptide-membrane interactions in supported planar bilayers: (1) indolicidin, a cationic 13 amino-acid peptide isolated from bovine neutrophils, as a model of antimicrobial peptide-membrane interactions, and (2) NAP-22 peptide, a cationic myristoylated peptide crucial for neuronal growth and plasticity, as a model of protein-induced lipid recruitment. Using this combined AFM-fluorescence approach with supported planar bilayers, we showed that: (1) the attachment of a fluorescent dye molecule can alter the physical properties of the host lipid and inhibit the lipid-dye conjugate from associating with raft domains, (2) indolicidin preferentially associates with the more disordered fluid domain and induces gel domain lowering in a concentration- and lipid-dependent manner, and (3) NAP-22 peptide induces coalescence of raft domains at low peptide concentration and phase-immersion at high peptide concentration resulting the co-localization of cholesterol and phosphatidylinositol biphosphates. This work demonstrates the versatility of a combined AFM-fluorescence approach as well as its limitations of the current configurations.

Book excerpt: A complete examination of the uses of the atomic force microscope in biology and medicine This cutting-edge text, written by a team of leading experts, is the first detailed examination of the latest, most powerful scanning probe microscope, the atomic force microscope (AFM). Using the AFM, in combination with conventional tools and techniques, readers gain a profound understanding of the cell, subcellular organelles, and biomolecular structure and function. The text begins with three chapters describing the molecular machinery and mechanism of cell secretion and membrane fusion in cells, using approaches that combine AFM, electron microscopy, X-ray diffraction, photon correlation spectroscopy, molecular biology, biochemistry, and electrophysiology. The discovery of a new cellular structure the "porosome" or fusion pore--the cells secretory machinery, the molecular mechanism of membrane fusion in cells, and the expulsion of intravesicular contents during cell secretion are outlined in the first three chapters. The book also covers: * Identification of the "porosome" in the growth hormone secreting cell of the pituitary gland * Probing the structural and physical properties of microbial cell surfaces * Scanning probe microscopic characterization of the higher plant cell wall and its components * Case studies of nano drug delivery systems using engineered dendrimers * AFM techniques for studying living cells * Investigating the intermolecular forces of leukocyte adhesion molecules * Protein-protein interactions * Micromechanical properties of lipid bilayers and vesicles The text concludes with four chapters that examine new and emerging approaches in the use of force microscopy in biology and medicine. This text is ideal for advanced undergraduate and graduate students and researchers in cell and molecular biology, genetics, genomics, physiology, neuroscience, biophysics, and biochemistry. Not only does it provide the theory, but also practical considerations such as the selection of the right tools and approach.

Available in PDF, EPUB and Kindle. Book excerpt: Atomic force microscopy (AFM) is part of a range of emerging microscopic methods for biologists which offer the magnification range of both the light and electron microscope, but allow imaging under the 'natural' conditions usually associated with the light microscope. To biologists AFM offers the prospect of high resolution images of biological material, images of molecules and their interactions even under physiological conditions, and the study of molecular processes in living systems. This book provides a realistic appreciation of the advantages and limitations of the technique and the present and future potential for improving the understanding of biological systems.

This book was released on 2012-03-07 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The atomic force microscope (AFM) has become one of the leading nanoscale measurement techniques for materials science since its creation in the 1980's, but has been gaining popularity in a seemingly unrelated field of science: biology. The AFM naturally lends itself to investigating the topological surfaces of biological objects, from whole cells to protein particulates, and can also be used to determine physical properties such as Young's modulus, stiffness, molecular bond strength, surface friction, and many more. One of the most important reasons for the rise of biological AFM is that you can measure materials within a physiologically relevant environment (i.e. liquids). This book is a collection of works beginning with an introduction to the AFM along with techniques and methods of sample preparation. Then the book displays current research covering subjects ranging from nano-particulates, proteins, DNA, viruses, cellular structures, and the characterization of living cells.

Available in PDF, EPUB and Kindle. Book excerpt: The cellular membrane is a complex biological entity, far from being an inert assembly of protein and lipids which separates cells from the surrounding environment. A multitude of biological processes, ranging from active transport of ions into and out of the cell, to the immune response, are regulated at the level of the plasma membrane. The understanding of their molecular basis is among the central goals of modern biological research. In order to dissect the complexity of actual cell membranes, which involves a very complex network of intermolecular interactions, a "divide and conquer" strategy proves very useful. To this end, researchers try to isolate molecules from complex biological contexts to understand their function in simple model systems under controlled conditions. A variety of model membranes have thus been developed in order to gain insight into membrane processes. This approach has resulted in a deeper knowledge on how lipids and proteins interact and how these interactions govern the function of cellular membranes. In the recent past in fact, a connection has been established between the lateral structure of the plasma membrane and its biological function. Furthermore, a large range of biophysical techniques have been used to characterize protein-lipid microdomains. For example, atomic force microscopy (AFM) is a powerful technique which allows a highly detailed topographical characterization of lipid domains in physiological conditions. While AFM imaging offers an extremely high spatial resolution, up to the nanometer scale, the limited image acquisition speed (~minutes) can pose a severe drawback in adequately studying fast dynamic processes. On the other hand, fluorescence based imaging techniques are much faster (~10-3-100 s), but certainly lack the high spatial resolution that AFM offers. FCS in particular can also provide information about dynamic processes, like diffusion of fluorescent membrane components. For these reasons, implementing a.

Available in PDF, EPUB and Kindle. Book excerpt: Presents a multi-disciplinary perspective on the physics of life and the particular role played by lipids and the lipid-bilayer component of cell membranes. Emphasizes the physical properties of lipid membranes seen as soft and molecularly structured interfaces. By combining and synthesizing insights obtained from a variety of recent studies, an attempt is made to clarify what membrane structure is and how it can be quantitatively described. Shows how biological function mediated by membranes is controlled by lipid membrane structure and organization on length scales ranging from the size of the individual molecule, across molecular assemblies of proteins and lipid domains in the range of nanometers, to the size of whole cells. Applications of lipids in nano-technology and biomedicine are also described.
