Clinical and molecular aspects of motoneurone diseases: animal models, neurotrophic factors and Bcl-2 oncoprotein.

Abstract
Animal models of motor neurone disease (MND) are being increasingly used for screening molecules with clinical potential. A number of different treatments to decrease the progression of neuronal cell loss have been proposed; these include: Bcl-2 (B-cell leukaemia oncogene-2), neurotrophic factors, glutamate receptor inhibitors and Ca2+ channel antagonists. In this review Yves Sagot, Richard Vejsada and Ann C. Kato focus on the effects of neurotrophic factors and Bcl-2, both of which have been shown to prevent cell death in various experimental paradigms. Studies performed in animal models of MND have confirmed the potential of these molecules to support motoneurone survival. Some of them have been shown to act in synergy and these results are discussed in the context of molecular mechanisms leading to collaborative and synergistic activities, and also with respect to presumptive subpopulations of motoneurones, which express diverse receptors for neurotrophic factors. Finally, the current status of clinical trials for amyotrophic lateral sclerosis using neurotrophic factors will be discussed, as well as recent reports that neurotrophic factors can exert adverse effects on neuronal survival.
