Book Description
Dictyostelium discoideum is a simple but fascinating eukaryotic microorg- ism, whose natural habitat is deciduous forest soil and decaying leaves, where the amoebae feed on bacteria and grow as independent single cells. Exhaustion of the bacterial food source triggers a developmental program, in which up to 100,000 cells aggregate by chemotaxis towards cAMP. Morphogenesis and cell different- tion then culminate in the production of spores enabling the organism to survive unfavorable conditions. Dictyostelium offers unique advantages for studying f- damental cellular processes with the aid of powerful molecular genetic, bioche- cal, and cell biological tools. These processes include signal transduction, chemotaxis, cell motility, cytokinesis, phagocytosis, and aspects of development such as cell sorting, pattern formation and cell type differentiation. Recently, D- tyostelium was also described as a suitable host for pathogenic bacteria in which one can conveniently study the process of infection. In addition, Dictyostelium has many of the experimental conveniences of Saccharomyces cerevisiae and is pr- ably the best experimentally manipulatable protozoan, providing insight into this diverse group of organisms, which includes some of the most dangerous human parasites. The recent completion of the Dictyostelium genome sequencing project strengthens the position of D. discoideum as a model organism. The completed genome sequence and other valuable community resources constitute the source for basic biological and biomedical research and for genome-wide analyses.

Book Description
Chemokines and their receptors play a central role in the pathogenesis of numerous, perhaps all, acute and chronic inflammatory diseases. About 50 distinct chemokines produced by a variety cell types and tissues either c- stitutively or in response to inflammatory stimuli are involved in a plethora of biological processes. These small secreted proteins exert their exquisitely variegated functions upon binding to a family of seven-transmembrane spanning G-protein coupled receptors (GPCRs) composed of almost 20 distinct entities. The biological activities of chemokines range from the control of leukocyte trafficking in basal and inflammatory conditions to the regulation of hema- poiesis, angiogenesis, tissue architecture, and organogenesis. The basis for such diversified activities rests, on one hand, upon the ubiquitous nature of chemokine production and chemokine receptor expression. Virtually every cell type can produce chemokines and expresses a unique combination of chemokine receptors. On the other hand, chemokine receptors make use of a flexible and complex network of intracellular signaling machineries that can regulate a variety of cellular functions ranging from cell migration, growth, and differentiation to death. As knowledge of the size of chemokine and chemokine receptor families rapidly reaches completeness, much is still to be uncovered in terms of fu- tional architecture of the chemokine system. The disparity between the large number of chemokines and that smaller number of receptors is balanced by the promiscuity in ligand–receptor interactions, with multiple chemokines binding to the same receptor and several chemokines binding to more than one receptor.

Book Description
Noted biologist and author John Tyler Bonner has experimented with cellular slime molds for more than sixty years, and he has done more than anyone else to raise these peculiar collections of amoebae from a minor biological curiosity to a major model organism--one that is widely studied for clues to the development and evolution of all living things. Now, five decades after he published his first pioneering book on cellular slime molds, Bonner steps back from the proliferating and increasingly specialized knowledge about the organism to provide a broad, nontechnical picture of its whole biology, including its evolution, sociobiology, ecology, behavior, and development. The Social Amoebae draws the big lessons from decades of research, and shows how slime molds fit into and illuminate biology as a whole. Slime molds are very different from other organisms; they feed as individual amoebae before coming together to form a multicellular organism that has a remarkable ability to move and orient itself in its environment. Furthermore, these social amoebae display a sophisticated division of labor; within each organism, some cells form the stalk and others become the spores that will seed the next generation. In The Social Amoebae, Bonner examines all these parts together, giving a balanced, concise, and clear overview of slime mold biology, from molecules to cells to multicells, as he advances some unconventional and unexpected insights.

Book Description
Electroporation is one of the most widespread techniques used in modem molecular genetics. It is most commonly used to introduce DNA into cells for investigations of gene structure and function, and in this regard, electroporation is both highly versatile, being effective with nearly all species and cell types, and highly efficient. For many cell types, electroporation is either the most efficient or the only means known to effect gene transfer. However, exposure of cells to brief, hi- intensity electric fields has found broad application in other aspects of biological research, and is now routinely used to introduce other types of biological and analytic molecules into cells, to induce cell-cell fusion, and to transfer DNA directly between different species. The first seven chapters of Electroporation Protocols for Micro organisms describe the underlying theory of electroporation, the com mercially available instrumentation, and a number of specialized electroporation applications, such as cDNA library construction and interspecies DNA electrotransfer. Each of the remaining chapters pre sents a well developed method for electrotransformation of a particular bacterial, fungal, or protist species. These chapters also serve to intro duce those new to the field the important research questions that are currently being addressed with particular organisms, highlighting both the major advantages and limitations of each species as a model organ ism, and explaining the roles that electroporation has played in the development of the molecular genetic systems currently in use.

Book Description
Since their discovery in 1869, the dictyostelids have attracted the attention of scientists in a wide variety of fields. This interest has stemmed from their peculiar lifestyle and developmental properties, which were shaped by the evolutionary forces that generated multicellularity during eukaryotic evolution. More recently, the dictyostelids have gained attention due to the striking similarities found at the genomic, cellular and biochemical levels with human cells, which has propelled the species Dictyostelium discoideum to become a model system for biology and medicine in many laboratories. This book covers the latest advances in our knowledge of these extraordinary organisms with topics spanning from their evolutionary history, ecology and diversity to the recent discoveries regarding their cellular and molecular biology.

Book Description
Dictyostelia are soil amoebae capable of extraordinary feats of survival, motility, chemotaxis, and development. Characterised by their ability to transform from a single-celled organism into an elaborate assemblage of thousands of synchronously-moving cells, Dictyostelids are often referred to as 'social amoebae', and have been the subjects of serious study since the 1930s. Research in this area has been instrumental in understanding many problems in cellular biology. Beginning with the history of Dictyostelids and discussing each stage of their development, this book considers the evolution of this unique organism, analyses the special properties of the Dictyostelid genome, and presents in detail the methods available, at the time of the book's original publication in 2001, to manipulate their genes. Representing the synthesis of such material and with an emphasis on combining classical experiments with modern molecular findings, this book will be essential for researchers and graduates in developmental and cellular biology.
