title: Receptors in neurodegenerative diseases.
abstract: The ability of trophic factors to regulate developmental neuronal survival and adult nervous system plasticity suggests the use of these molecules to treat neurodegeneration associated with human diseases, such as Alzheimer's, Huntington's and Parkinson's disease, of amyotrophic lateral sclerosis and peripheral sensory neuropathies. Recent biological data on the neutrotrophins NGF and BDNF, on GDNF, CNTF and IGF-I are discussed together with first results from clinical trials. Literature is presented on the three-dimensional structures of these trophic factors and on models proposed for ligand-receptor interactions. Substantial progress has been made in the understanding of the mechanisms of apoptosis. The cascade consisting of interaction of apoptosis-inducing ligands with death receptors, the coupling of this complex to adaptor proteins via death domains, the further recruitment of procaspases via death effector or caspase recruitment domains and the execution of cell death via the effector caspases is briefly outlined.
