Definitions

• the invention relates to therapeutics and methods for treating Parkinson's disease.
• Parkinson's disease is a progressive neurodegenerative disease whose primary clinical features include motor abnormalities, such as resting tremor, bradykinesia and rigidity (Fahn and Sulzer, 2004) .
• PD is characterized by the loss of dopaminergic neurons in the substantia nigra pars compacta and the presence of inclusion bodies, called Lewy bodies and Lewy neurites, in the surviving neurons of the same region
• Fibrillar aggregates of ⁇ -synuclein seem to be the main component of Lewy bodies and Lewy neurites, and these are now considered the most reliable PD marker for postmortem diagnosis (Spillantini et al . 1998). Because ⁇ -synuclein is a cytosolic protein it has been assumed that the pathogenic changes and effects induced by the protein occur in the cytoplasm and are limited to the single cell. However, recent studies of extracellular ⁇ -synuclein suggest that the scope of pathogenic action goes beyond the cytoplasm of its origin (Lee, 2008) .
• Extracellular ⁇ -synuclein appears to be delivered by unconventional exocytosis of intravesicular ⁇ -synuclein, although the exact mechanism has not been characterized. Intravesicular ⁇ -synuclein is prone to aggregation and is the potential source of extracellular aggregates.
• Alpha synuclein can readily incorporate into membranes and can be found in synaptic vesicles and on the cell membrane. There are not many well -structured models for the mechanisms of toxicity. Recent studies illustrate a possible role for an ⁇ - synuclein pore-like protofibrils in the pathogenesis of Parkinson's disease (Tsigelny et al . , 2007; Lee et al . , 2002; Voiles and Lansbury, 2002) .
• oligomeric ⁇ -synuclein can form annular structures with a central pore (Voiles and Lansbury 2003) . These aggregates can bind to membranes (Voiles et al . 2001) and their membrane permeabilizing action has been demonstrated in synthetic model membranes, such as phospholipid liposomes (Voiles et al . 2001) and planar bilayer membranes (Kayed et al . 2004) . Insertion of these aggregates into the cell membrane would have a catastrophic effect on cell viability due to the free exchange of ions and small metabolites between the cytoplasm and the extracellular space.
• the present invention provides a filamentous bacteriophage for use in treating Parkinson's disease or susceptibility to Parkinson's disease, and a method for treating a patient suffering from or susceptible to Parkinson's disease (PD) .

• Figures 4A and 4B show the reduction of AS aggregates by phage (helper) as visualized (Fig 4A) and measured in an ELISA (Fig 4B) using an ⁇ -synuclein polyclonal antibody in an ⁇ - synuclein filter retardation assay.
• Figure 5A shows Western blot analysis of the membrane fraction of SH-SY5Y cells, demonstrating the presence of various ⁇ -synuclein (AS) oligomers
• Figure 5B shows ELISA assay for measurement of oligomers after M13 treatment.
• AS is detected with a polyclonal antibody against AS (Sigma)
• Fig. 5B the amount of AS oligomers from the membrane fraction was quantified in an ELISA specific for AS oligomers which are detected with a monoclonal antibody against AS (Sigma, clone Syn 211) .
• Figure 6 is a graph showing reduction in AS reactivity after interaction with M13 phages compared to vehicle. The data is expressed as a ratio of the average number of neuronal aggregates of AS observed in one hemisphere of the brain injected with M13 compared to the other hemisphere injected with PBS vehicle (+M13) . In the -M13 control, both hemispheres were injected with PBS vehicle.

• M13 filamentous phages were prepared from infected TGl Escherichia coli cultures with M13K07 helper phage (New England Biolabs, Beverly, MA) in 2YT broth containing 50 ⁇ g/ml kanamycin (Sigma-Aldrich, St. Louis, MO) . Bacterial cells were centrifuged (8300xg, 15 min) , and phages were precipitated from the supernatant by addition of 1/5 (wt/vol) of 16.7% polyethylene glycol (PEG) and centrifuged (14,000xg, 1 h at 4°C) .
• PEG polyethylene glycol
• the pellet was resuspended in sterile phosphate-buffered saline (PBS) (3% of the supernatant volume) . Residual bacteria were removed by centrifugation at 6,000xg for 15 min, and the phages then subjected to PEG-NaCl precipitation.

Spherical phages were generated by incubation of filamentous phages in PBS with an equal volume of chloroform.
• PBS sterile phosphate-buffered saline
• Alpha-synuclein fibrils and filamentous phages were visualized by electron microscopy.
• Samples were also viewed by transmission electron microscopy (TEM) . Samples were loaded on carbon grids and were coated with uranyl acetate. In the sample containing only the ⁇ - synuclein peptide, significant amounts of complex fibrils in a dense form were detected (Fig. 2B, left panel) . A substantial reduction in the amount and complexity of fibrils was viewed in the sample incubated with 10 11 phages, while in the sample incubated with 10 12 phages, no fibrils were detected and only amorphous aggregates were visible (Fig. 2B, middle and right panels) .

• alpha-synuclein expression was determined by Western blot.
• SH-SY5Y cells stably transfected to over-express A53T ⁇ -synuclein were grown in 10 cm dishes and maintained in DMEM:Ham's F12 (1:1) modified medium containing 1% non-essential amino-acids (NEAAs) and supplemented with FCS (10%) , glutamine (2 mM) , penicillin-streptomycin solution (1%) (Biological Industries), in humidified incubator at 37°C with 5% CO 2 .
• ⁇ -synuclein For separation of ⁇ -synuclein, the lysis procedure was performed using the cell extraction described by Lee et al . (2004) as modified by the laboratory of the present inventors. Briefly, cells were rinsed with PBS, trypsinized with 1.5ml trypsin per dish collected to a 15ml tube, centrifuged and washed again with PBS followed by collection to an Eppendorf tube.
• Equal numbers of cells per 10 cm dish were added and allowed to reach 80% confluency. At that time, cells were treated with different amounts of phage for 24 and 72 hr. Cells were then collected from each plate and lysed and analysed, as described below. Differentiated SH-SY5Y cells overexpressing wild type ⁇ -synuclein were incubated with a total of IxIO 12 phages for a period of 3hr. or overnight at 37°C. The soluble and insoluble fractions were extracted and the insoluble fraction was filtered through a 0.2 ⁇ m nitrocellulose membrane. The amount of ⁇ -synuclein aggregates retained on the filter was higher in the untreated cells (Fig. 4A) .
• Alpha- synuclein is a natively unfolded protein localized at presynaptic terminals. AS readily incorporates into membranes through the N-terminus and thus exists in the cell in two forms: a membrane bound and a disordered cytosolic form. Accumulating data indicate that the membrane form of AS plays a role in cellular toxicity. Protofibrils can form annular structures embedded on the cell membrane and cause membrane permeability. It was recently demonstrated that AS has a propensity for higher aggregation in the presence of lipids and that the membrane aggregates can induce aggregation of the cytosolic form of AS.
• SH-SY5Y cells were differentiated using retinoic acid and were incubated overnight with wild-type phages at I 011 phages/ ml.
• the membrane fractions were extracted the following day and samples of each extraction were measured for the amount of AS oligomers in an ELISA designed to recognize only oligomeric species of AS (Fig. 5B) .
• a significant reduction in AS oligomers from the membrane fraction was measured in SH-SY5Y cells following incubation with filamentous phages.
• wild-type phages affect AS on the plasma membrane, possibly via direct interaction with AS through a previously demonstrated region of interaction located at amino acids 73-85 of the NAC region of AS. It is also possible that due to the long incubation of the cells with phages, a small percentage of the phages are internalized into the cells affecting other membranous compartments in the cell other than the plasma membrane. Binding of the phages to the cells with possible internalization may promote clearance of alpha-synuclein from the plasma membrane through activation of lysosmal degradation.
• PDGF ⁇ -synuclein transgenic mice D line
• non- transgenic mice aged 7 months received intra-hippocampal injections with M13 phage at IxIO 14 and the brains were analyzed 7 days later by IHC with antibodies against alpha-synuclein, M13 and lbal (for microglia activation) .
• Abundant M13 immunoreactivity was observed in alpha-synuclein Tg mice injected with M13.
• M13 immunostaining was observed in neuronal cell bodies in the neocortex and hippocampus . In the hippocampus M13 immunostaining was also abundant in the neuropil .
• the average number of neuronal aggregates of ⁇ -synuclein was measured in both hemispheres of the brain after M13 injection in one hemisphere and phosphate buffered saline (PBS) vehicle in the other hemisphere, and the ratio between the measurements in the separate hemispheres is shown in Figure 6.
