Abstract:
Transgenic animal models are useful in studying the features of APP- and PS1-linked FAD and SOD1-linked FALS. These models help to investigate the nature of the cellular/biochemical/molecular alterations in neural tissue; the character and evolution of neuronal and/or glial abnormalities; the ways mutant proteins cause damage to neurons; and the biochemical pathways associated with cell death. New technologies will help to define changes in a variety of genes/gene products and the events and conformational changes in mutant proteins that are implicated in pathogenic cascades. It is hoped such study will result in novel treatments for testing in transgenic models that can then be translated into new treatments for human neurodegenerative diseases.
