Given a question and a context passage, generate the answer having the word or phrase from the context passage. Here, the answer should be a shortest continous span from the passage.

Example Input: Context: Alpha-synuclein(-syn) is the main protein component of Lewy bodies (LBs), that together with nigrostriatal dopamine neuron loss constitute typical pathological hallmarks of Parkinson's disease (PD). Glutamate N-methyl-d-aspartate receptor (NMDAR) abnormalities, peculiarly involving NR2B-containing NMDAR, have been observed in the brain of PD patients and in several experimental models of the disease. Recent findings, indicating that -syn can modulate NMDAR trafficking and function, suggest that this protein may be a pivotal regulator of NMDAR activity. Prompted by these evidences, we used fluorescence immunocytochemistry, western blotting and ratiometric Ca(2+) measurements to investigate whether wild type (wt) or C-terminally truncated -syn can specifically modulate NR2B-containing NMDAR levels, subcellular trafficking and function. In addition, we evaluated whether the exposure of primary cortical neurons to increasing concentrations of rotenone could differentially regulate NR2B levels and cell viability in the presence or in the absence of -syn. Our results indicate that both wt and C-terminally truncated -syn negatively modulate NR2B-containing NMDAR levels, membrane translocation and function. Moreover, we found that absence of -syn abolishes the rotenone-dependent decrease of NR2B levels and reduces neuronal vulnerability in primary cortical neurons. These findings suggest that -syn can modulate neuronal resilience by regulating NR2B-containing NMDAR, whose specific alterations could connect -syn pathology to neuronal degeneration in PD. 
 Question: Which is the primary protein component of Lewy bodies?
Example Output: αsyn

Example Input: Context: Clay gets up from his trailer at the beach and drives to Mr. Jimmy's lush house, where he mows the lawn.Mr. Jimmy has a visit from David, who is concerned about his health. He then goes out to chat with Clay, his new gardener, and invites him to swim in the pool after he is done working. Clay says he needs to do another lawn later.An academic named Edmund Kay comes to visit Mr. Jimmy, and expresses his deep enthusiasm for his films. Jimmy takes him out back to the pool, and recalls his youth in London, and then his movement into movies and on to Hollywood.Mr. Jimmy becomes bored with Kay's questions, and suggests that Kay begin removing clothing in exchange for his answers. Kay begins disrobing to each of Jimmy's tales about homosexuals in Hollywood and making Frankenstein.Jimmy then gets lightheaded and needs Kay's help to get inside and lie down. His maid Hanna scolds him for chasing boys after just returning from the hospital.Jimmy goes to a doctor who explains that he had a stroke which has left his brain somewhat impaired.Jimmy sees Clay working out in the garden and invites him to talk over iced tea in his painting studio. Jimmy tells him he directed the first two Frankenstein movies, and they talk about his paintings. Jimmy tells Clay he has an expressive head and asks him to model for pay; Clay agrees.Clay arrives at Jimmy's house and Hanna asks if he is going to hurt him. Clay is confused, and she withdraws the question. Clay sits down in the studio to model for Jimmy, who asks him to remove his shirt, even though he only plans to draw his face. Jimmy begins to draw, telling Clay of a memory he has about eating fat drippings as a poor child. He explains how different he was from his family, more talented, more intelligent.Clay goes to a bar and boasts that a famous director is drawing him. Betty the bartender, whom Clay has slept with, turns on The Bride of Frankenstein on TV; meanwhile, Jimmy watches at home with Hanna. The others at the bar criticize the film for not being scary. Clay seems to understand the monster's feelings of loneliness.Flashback: Jimmy directs the performers on the set of Bride of Frankenstein.Clay and Betty talk outside the bar, and he gets upset that she does not want to sleep with him again.Clay calls his parents from a payphone but does not want to talk much.Jimmy dreams that Clay is Dr. Frankenstein, replacing his brain and electrifying him.Hanna tells Clay that Jimmy would like him to have lunch. The two talk as she cooks, and Hanna tells him he should be married. Hanna tells Clay that Jimmy commits unspeakable sins of the flesh, buggery. She is surprised that Clay did not know.Jimmy and Clay have a rather fancy lunch. Jimmy tells Clay that he had hoped Bride of Frankenstein would be seen as a comedy. Jimmy asks Clay to pose for an hour after lunch, and he declines. Jimmy explains that he had a "husband" named David, and Clay asks about his homosexuality. They smoke cigars, and Clay agrees to pose.During the sitting, Jimmy talks about how he made the successful Show Boat and then tried to make his WWI masterpiece The Road Back but the studio butchered it. He says he always wanted to go back to movies, but that was the end. He also broke up with David thereafter. Jimmy begins to describe how he used to have many male models, all naked, which upsets Clay so much he gets mad and storms out.Clay goes to Betty's bar but she is not there. He finds another woman and has sex with her in the parking lot.Clay returns to Jimmy's house and says he will sit for him again if he eases up on the locker room talk. Jimmy is curious that Clay has never known any gay men before, not even when he was in the Marines. Jimmy recalls a young soldier from WWI he mentored in the trenches, then becomes quite upset, looking at Clay intensely
