How protein chaperones protect cells from neurodegenerative diseases Including contributions from leading experts, Protein Chaperones and Protection from Neurodegenerative Diseases provides an in-depth exploration of how protein chaperones are involved in shielding cells from toxic aggregated or misfolded protein states that cause ALS, Parkinson's, and related diseases. Examining how different protein chaperones ameliorate the toxicity of proteins that are known to cause neurodegenerative damage, the book addresses both research and clinical perspectives on chaperone and anti-chaperone properties. The intersection of molecular chaperones and neurodegeneration is an intensely studied area, partly because of the potential for manipulating the expression of molecular chaperones to thwart the progression of debilitating diseases, and partly because of the ever-aging global population. Discussing the potential to harness the power of protein chaperones, and future directions for research, discovery, and therapeutics, this book is essential reading for scientists working in the fields of biochemistry, molecular medicine, pharmacology and drug discovery, biotechnology and pharmaceutical companies, advanced students, and anyone interested in this cutting-edge topic.

The heat shock, or cell stress, response was first identified in the polytene chromosomes of Drosophila. This was later related to the appearance of novel proteins within stressed cells, and the key signal stimulating this appearance was identified as the presence of unfolded proteins within the cell. It is now known that this is a key mechanism enabling cells to survive a multitude of physical, chemical and biological stresses. Since the promulgation of the ‘molecular chaperone’ concept as a general cellular function to control the process of correct protein folding, a large number of molecular chaperones and protein folding catalysts have been identified, and it has been recognized that not all molecular chaperones are stress proteins and vice versa. The discovery of molecular chaperones as folding proteins went hand-in-hand with their recognition as potent immunogens in microbial infection. It was subsequently shown that administration of molecular chaperones such as Hsp60, Hsp70 or Hsp90 could inhibit experimental autoimmune diseases and cancer. More recently evidence has accumulated to show that certain molecular chaperones are also present on the surface of cells or in extracellular fluids. A new paradigm is emerging: at least some molecular chaperones are secreted proteins with pro- or anti-inflammatory actions, regulating the immune response in human diseases such as coronary heart disease, diabetes and rheumatoid arthritis. In addition to having direct effects on cells, molecular chaperones can bind peptides and present them to T cells to modulate immune responses. This may be significant in the treatment of cancer. This is the first book bringing leading researchers in this field together to review and discuss: our current knowledge of cell stress response and molecular chaperones the changing paradigms of protein trafficking and function cell stress proteins as immunomodulators and pro- and anti-inflammatory signalling molecules the role of these proteins in various chronic diseases and their potential as preventative or therapeutic agents. The Biology of Extracellular Molecular Chaperones is of particular interest to immunologists, cell and molecular biologists, microbiologists and virologists, as well as clinical researchers working in cardiology, diabetes, rheumatoid arthritis and other inflammatory diseases.
