This book presents much of the exciting new information on mechanisms of
neurodegenerative disorders that was presented at the XVth International
Spring Symposium on Health Sciences at George Washington University in
Washington, D.C. The organization of the symposium as weIl as the
chapters within this book were based upon fundamental molecular and
cellular mechanisms of neurodegeneration rather than upon different
clinically defined disorders, in order to emphasize the commonality of
cause rather than effect. The first part of the book is devoted to the
relationships between selective vulnerability of different neuronal cell
types to injury and their functional characteristics related to the
transport, binding, and responses for excitatory amino acids, e.g.,
glutamate, as weIl as other neurotransmitters involved in toxicity.
These relationships are studied in the context of neurodegeneration
associated with several disorders including Parkinson's disease,
amyotrophic lateral sclerosis (ALS), cerebral ischemia, and AIDS
dementia. Part 11 emphasizes the role of amyloid proteins in
neurodegeneration but also covers other molecular and genetic risk
factors, e.g., expression of different apo lipoprotein isoforms and the
involvement of abnormal superoxide dismutase in neuropathology. These
topics are applied primarily to the aging brain, Alzheimer's disease,
and ALS.
