Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -Signaling by diffusible morphogens, such as Hedgehog, Wingless, TGF-, and various growth factors, is vital for developmental patterning, ensuring that distinct differentiated cell types appear in the right place and at the right time in forming tissues. The expert contributors to this volume discuss the roles of morphogen gradients in organisms from yeast to humans. They examine the regulation of morphogen synthesis, trafficking, and diffusion, as well as the complex webs of signaling mechanisms and transcriptional responses in recipient cells. The book is a vital reference for developmental biologists and cell biologists wishing to know how cell fate is determined during embryogenesis.

Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -Parkinson's Disease is an incurable neurodegenerative disease characterized by a progressive loss of dopaminergic neurons that leads to slowness of movement, muscle rigidity, and tremors. Insoluble aggregates of proteins such as alpha-synuclein accumulate in the affected neurons, which also appear to be subject to oxidative stress. This collection from Cold Spring Harbor Perspectives in Medicine discusses recent work that has begun to uncover the molecular mechanisms that underlie the condition, including studies that implicate dysfunction of mitochondrial proteins such as parkin and pink1.

Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -This volume includes contributions covering each of the main junction types as well as the more specialized junctions of neuronal and immune cells. It covers their assembly and structure, importance in signal transduction, and roles in development, normal tissue homeostasis, and diseases.

Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -The main task of Tolerance is to reorient discussions in democratic theory so as better to theorize how tolerance can operate as an active force in the context of deep pluralism. The objective is to develop a theory of active tolerance attentive to the many different ways in which societies can become tolerant, and to discuss what might get lost, conceptually as well as politically, if we don't pay attention to how active tolerance subsists within other practices of tolerance. Tolerance exceeds existing accounts, Tønder argues, not because it cannot be domesticated for the purposes of either restraint or benevolence, but because this domestication does not preclude the possibility of another, more active tolerance.

Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -The transplantation of organs such as the heart, kidney, and lungs is an important means of replacing seriously damaged or diseased body parts. However, a transplanted organ may fail if the recipient's immune system mounts a response to it. Transplant patients are usually prescribed a life-long course of immunosuppressive medication, but these drugs can have adverse effects, including increased risk of infection and cancer. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Medicine provides a current and comprehensive review of the molecular mechanisms behind graft rejection and how they may be overcome. Contributors discuss immunosuppressive drug therapies and tolerance induction strategies, including the use of regulatory T cells, mesenchymal stromal cells, and lymphodepletion. They describe how mouse and non-human primate models have been used to gain insight into the immunobiology of transplantation and to test therapeutic approaches. Clinical considerations, such as donor selection, organ preservation, surgery, and post-operative care, are also covered. This volume includes discussion of the emerging field of regenerative medicine and the bioethical issues surrounding organ transplantation, and provides historical background to the field. It is an essential reference for immunologists, pharmacologists, clinicians, and all who are working to improve this remarkable medical procedure.

Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -In sexually reproducing organisms, germ cells give rise to gametes and serve as the link between generations. A key event during germ cell development is the decision to leave mitosis and enter meiosis, leading to the formation of mature eggs and sperm. Germ cell development involves unique gene expression programs and the establishment of epigenetic marks that ensure success during fertilization and embryo development. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology reviews the biology of germ cells in metazoans. The contributors describe the undifferentiated state of germline stem cells, the triggers for meiotic entry, and the transcriptional and post transcriptional controls during spermatogenesis and oogenesis that lead to the formation of mature gametes. The expression of sex linked genes and the establishment of genomic imprinting in the germline are also covered. This volume, which includes discussions of gamete recognition proteins, egg activation, and genetic reprogramming following nuclear transfer, is an indispensable reference for cell, molecular, and developmental biologists and anyone wishing to understand the implications of germ cell biology for reproductive technologies.

Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -Studies of mammary gland biology are critically important given the prevalence of breast cancer. This organ represents an excellent model system for research into developmental mechanisms, gene regulation, tissue organization, hormonal action, secretion, and stem cell biology. This book provides valuable lessons for all cell, developmental, and cancer biologists.

Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -The endoplasmic reticulum (ER) is an extensive network of membranes that folds, modifies, and transports proteins in eukaryotic cells. It also manufactures lipids and interacts extensively with other organelles, playing essential roles in cell growth and homeostasis. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology covers all aspects of ER morphology and function, as well as its interactions with the nucleus, Golgi, and mitochondria. Contributors examine how proteins translocate across the ER membrane, the processes that occur inside the ER lumen (e.g., folding, glycosylation, and disulfide bond formation), and how the proteins are packaged into vesicles and transported to the Golgi. They also review quality-control mechanisms that are employed by the ER to detect and eliminate misfolded or unassembled proteins. Lipid synthesis and transport are also discussed. This volume covers not only the biochemistry and cell biology of the ER, but also ER stress, metabolism, and the role of the ER in viral replication. Thus, it is an essential reference for cell biologists, physiologists, and pathologists interested in understanding the numerous functions of the ER.

Gebundene Ausgabe. Zustand: Wie neu. Gebraucht - Wie neu -Wnt proteins are signaling molecules that play critical roles during embryonic development and in the regeneration of adult tissues. They bind to Frizzled and LRP family receptors on the cell surface, triggering a series of events that cause -catenin to enter the nucleus and activate transcription factors that control cell fate and cell proliferation. Mutations in components of the Wnt pathway lead to developmental defects and are common in cancer. Written and edited by experts in the field, this collection from Cold Spring Harbor Perspectives in Biology covers all aspects of canonical Wnt signaling, as well as -catenin-independent Wnt signaling and cross-talk with other pathways. The contributors examine the numerous Wnt ligands; their production, secretion, and interactions with components of the extracellular environment; and details of the downstream signaling pathways that mediate the effects of Wnt proteins on cells. The roles of Wnt signaling in stem cell self-renewal, cell polarity, body-axis specification, wound healing, and other aspects of normal development and physiology are also covered. This volume includes discussion of Wnt signaling in cancer, skeletal defects, neurological disorders, and other human disease states. Thus, it is an indispensable reference for cell and developmental biologists as well as those, especially in the fields of stem cell biology and regenerative medicine, who are interested in targeting the Wnt pathway for therapeutic purposes.
