Abstract: The present invention is directed to a method of treating Parkinson's disease using arylcyclopropylamine compounds. The arylcyclopropylamine compounds have the following formula wherein R1, R2, R3, R4, R5 and R6 are described herein.

Abstract: Described herein are methods of treating Parkinson's disease using arylcyclopropylamine compounds.

Abstract: A method of treating a subject for Parkinson's disease comprises administering said subject a phenylisopropylamine in an amount effective to treat said Parkinson's disease. In some embodiments the method is used to treat at least a motor symptom of Parkinson's disease; in some embodiments the method is used to treat at least a non-motor symptom of Parkinson's disease.

Abstract: A method of treating a subject for a serotonergic neurotransmission dysregulation disorder, comprises administering the subject a serotonin enhancer (e.g., a serotonin reuptake inhibitor) in an amount effective to treat the disorder; and concurrently administering the subject 5-hydroxytryptophan in an amount effective to enhance the activity of the serotonin enhancer, (e.g., serotonin reuptake inhibitor). In preferred embodiments the disorder is depression, anxiety, or substance abuse.

Abstract: Recombinant or transgenic non-human mammals are described having a mutant tryptophan hydroxylase 2 (Tph2) gene resulting in altered synthesis of 5-hydroxytryptophan and serotonin in the brain. In some embodiments the mutant tryptophan hydroxylase 2 gene contains mouse R439H and/or P447R functional mutations, or their corresponding mutations in other species. Congenic non-human mammals having mutant tryptophan hydroxylase 2 genes are also provided. Methods of screening a compound for serotonergic activity or activity in treating a serotonergic neurotransmission dysregulation disorder are provided, which include administering a test compound to a recombinant non-human mammal and then detecting the presence or absence of serotonergic activity, or activity in treating a serotonergic neurotransmission dysregulation disorder, in the mammal. A cell such as a nerve cell (e.g.

Abstract: A method of screening a candidate compound for ?Arrestin mediated anti-G protein coupled receptor signaling activity is comprises: (a) contacting said candidate compound to a ?Arrestin signaling complex or a constituent thereof, under conditions in which a signaling complex is formed; and then (b) detecting the presence or absence of disruption of said signaling complex, disruption of said complex indicating said compound has ?Arrestin mediated anti-G protein coupled receptor signaling activity. Compositions and kits for carrying out the method are also described.

Abstract: A method of screening a subject for a serotonergic neurotransmission dysregulation disorder comprises detecting the presence or absence of an Tph2 mutation in the subject; and then determining that the subject is at increased risk of a serotonergic neurotransmission dysregulation disorder due to the presence or absence of the Tph2 mutation.
