BACKGROUND
Synucleinopathies also known as Lewy body diseases (LBDs), are
terized by degeneration of the dopaminergic system, motor alterations,
cognitive impairment, and formation of Lewy bodies (LBS) and/or Lewy es.
(McKeith et al., Neurology (1996) 47:1113—24). Synucleinopathies include
Parkinson's disease (including idiopathic Parkinson’s disease), Diffuse Lewy Body
e (DLBD) also known as Dementia with Lewy Bodies (DLB), Lewy body
variant of Alzheimer’s disease (LBV), Combined Alzheimer's and Parkinson disease,
pure autonomic failure and multiple system atrophy (MSA; e.g., Olivopontocerebellar
Atrophy, Striatonigral Degeneration and Shy—Drager Syndrome). Several nonmotor
signs and symptoms are thought to be gers for synucleinopathies in the
mal phase of the diseases (i.e, the presymptomatic, subclinical, preclinical, or
or period). Such early signs include, for example, REM sleep behavior
disorder (RBD), loss of smell and constipation (Mahowald et al., Neurology (2010)
75:488—489). Lewy body diseases continue to be a common cause for movement
disorders and cognitive deterioration in the aging population (Galasko eta1., Arch.
Neurol. (1994) 51:888-95).
Alpha—synuclein is part of a large family of proteins including beta— and
gamma— synuclein and synoretin. Alpha—synuclein is expressed in the normal state
associated with synapses and is ed to play a role in neural plasticity, learning
and memory. Several studies have implicated alpha-synuclein with a central role in
PD pathogenesis. The protein can ate to form insoluble fibrils in pathological
conditions. For example, synuclein accumulates in LBS (Spillantini et al., Nature
(1997) 388:839-40; Takeda et al., J. Pathol. (1998) 152:367-72; Wakabayashi et al.,
Neurosci. Lett. (1997) 239:45—8). Mutations in the alpha—synuclein gene regate
with rare familial forms of parkinsonism (Kruger et al., Nature Gen. (1998) 18:106—8;
Polymeropoulos, et al., Science (1997) 276:2045—7). Over expression of alpha
synuclein in transgenic mice (Masliah et al., Science (2000) 287: 1265—9) and
Drosophila (Feany et al., Nature (2000) 404:394-8) mimics several pathological
aspects of Lewy body disease. In addition, it has been suggested that soluble
oligomers of synuclein may be neurotoxic (Conway KA, et al., Proc Natl Acad Sci
USA (2000) 97:571—576; VollesMJ, Lansbury PT, Jr mistry (2003) 4227871—
7878). The accumulation of alpha-synuclein with similar morphological and
neurological tions in species and animal models as diverse as humans, mice, and
flies ts that this molecule contributes to the development of Lewy body disease.
