Abstract: The present invention relates to a pharmaceutical composition and health functional food for preventing or treating neurodegenerative diseases which include a flower extract of Daphne genkwa or fractions thereof as an active ingredient. The pharmaceutical composition and health functional food for preventing or treating neurodegenerative diseases are, not like extracts from stems and/or roots of Daphne genkwa, free from genotoxicity and have superior prophylactic or treatment effects against neurodegenerative diseases.

Abstract: The present invention relates to a pharmaceutical composition for preventing or treating neurodegenerative diseases comprising a diterpene, or a pharmaceutically acceptable salt thereof. Specifically, the diterpene of the present invention can prevent or treat neurodegenerative diseases caused by inhibition of Nurr1 activity by activating Nurr1 and inhibiting the inflammatory response.

Abstract: The present invention relates to a method for producing astrocytes comprising obtaining neural progenitor cells from stem cells so as to continuously produce astrocytes with high purity and same traits, followed by two steps of differentiating the neural progenitor cells into the astrocytes, and astrocytes produced therefrom. Since the method of preparing the astrocytes provided in the present invention enables not only production of the astrocytes with high purity and faster production of the astrocytes with same characteristics, but also rapid differentiation of the astrocytes using the neural progenitor cells when necessary, it can be widely used for effectively treating a patient with a disease which requires transplantation of the astrocytes.

Abstract: The present invention relates to a method for producing cholinergic neurons comprising obtaining neural progenitor cells from stem cells so as to continuously produce cholinergic neural cells with high purity and the same traits, followed by differentiating the neural progenitor cells into the cholinergic neurons, and cholinergic neurons produced therefrom. Since the method of preparing the cholinergic neurons provided in the present invention enables not only production of the cholinergic neurons with high purity, but also rapid production of the cholinergic neurons with the same traits, it can be widely used for effectively treating degenerative cranial nerve diseases such as Alzheimer's disease.

Abstract: The present invention relates to a pharmaceutical composition for preventing or treating Parkinson's disease, which comprises, as an active ingredient, a Rhodotypos scandens extract obtained by extracting the stem of Rhodotypos scandens with an organic solvent, and a food additive showing the effect of preventing or treating Parkinson's disease, the food additive comprising Rhodotypos scandens extract as an active ingredient. The Rhodotypos scandens extracts of the present invention may prevent or treat Parkinson's disease without producing any particular side effects, and therefore can be widely used for more safely treating Parkinson's disease.

Abstract: The present invention relates to: a pharmaceutical composition or a Nurr1 activating composition for the prevention or treatment of a neurodegenerative disease or a disease induced by impaired Nurr1 function, wherein the composition comprises an active ingredient in the form of genkwanin N or yuanhuacine, a Daphne genkwa extract comprising one or more of the above compounds, or a fraction thereof; or a functional food additive for preventing or alleviating a neurodegenerative disease or a disease induced by impaired Nurr1 function, wherein the additive comprises genkwanin N or yuanhuacine, a Daphne genkwa extract comprising one or more of the above compounds, or a fraction thereof; and a method for the prevention or treatment of a neurodegenerative disease or a disease induced by impaired Nurr1 function, wherein the method comprises the step of administering the pharmaceutical composition.
