Накратко на български
Невронните стволови клетки в мозъка на възрастни се изследват, за да се разбере как се контролира създаването на нови неврони. Това помага за разработването на нови методи за възстановяване на централната нервна система при дегенеративни и психични заболявания.

Final Activity Report Summary - STEM CELL REGULATION (Regulation of adult neural stem cell quiescence and proliferation)
According to WHO estimates, more than 20% of the European population will be aged 60 and above in 2020. The increase in the prevalence of age-related degenerative diseases and cancer poses an increasing challenge to European society and public health, and demands the development of new treatment strategies for these diseases. The goal of the STEM CELL REGULATION is to significantly contribute to the development of new treatment options for age-associated neuropsychiatric diseases by deciphering mechanisms that will promote the recruitment of stem cells for repair of the diseased central nervous system. The strategy of the research group is to identify the mechanisms that control the formation of neurons from stem cells under physiological and to translate these findings into strategies for stem cell-based regeneration in the disease context. Since its instalment in spring 2007, STEM CELL REGULATION has established a multidisciplinary research platform for the study of adult neurogenesis and neural stem cells. Our research has uncovered novel regulatory mechanisms that control the formation of new neurons from stem cells in the adult brain. Key findings are the identification of Notch- and Wnt-signalling as central regulators of the balance between stem cell maintenance and differentiation and the identification of the CREB-signalling pathway as a neural network activity controlled pathway that is essential for survival and functional integration of stem cell derived neurons. Moreover, the team has significantly contributed to the new concept, that cognitive dysfunction in neurodegenerative diseases may in part be related to stem cell failure and impaired adult neurogenesis. These achievements form the technological and scientific basis for our current projects that aim to promote stem cell activity and neurogenesis to ameliorate cognitive and to harness stem cells for repair in preclinical models for Parkinson's Disease. STEM CELL REGULATION has significantly contributed to the development of stem cell research and research in neuro-regeneration in Europe. The Marie Curie Excellence Team recruited of young talented researchers to the European Research Area and contributed to the education of junior researchers in neural stem cell biology and neuro-regeneration. Overall researchers from 6 countries (Turkey, Czech Republic, China, Austria, Germany, Greece) were part of the research team. Four PhD students are expected to finish their thesis work with excellent scientific results by the end of 2011. The team coordinates one research consortium and is part of two additional transnational research networks involving laboratories from Germany and Austria that investigate the potential of neural stem cells for repair. Finally, our team has established collaborations with partners throughout Europe (Spain, Switzerland, France, Austria, Sweden), thereby strengthening research interactions and collaborative work in the European Research Area. The recognition of our research is documented by the publication record, active collaborations with national and international partners, invitations to international symposia, and awards of highly competitive grants and PhD student stipends. Most importantly, the research group is integrated in several research networks that focus on the development of stem cell-based regenerative therapies and that are funded by the BMBF, the State of Bavaria, and the Helmholtz Association. It is also noteworthy, that the group leader successfully passed the tenure track evaluation in 2010. Finally, the research group has significantly contributed to the career development and education of young researchers and to public education in science. Since the start of the junior research group, two PhD students have finished their thesis with excellent marks. Postdoctoral students have obtained leading positions in pharmaceutical industry and in scientific administration.

Цел на проекта
According to WHO estimates, more than 20% of the European population will be aged 60 and above in 2020. The increase in age-associated neurological diseases such as Alzheimer's disease, Parkinson's disease and stroke will creates growing health-economic problems for European society and will have a major impact on the quality-of-life of the individual. Current treatment options for neurological diseases are limited and fail to lead to functional recovery. Adult neural stem cells (NSCs) hold great promise for restorative therapy because of their privileged location within the central nervous system and their potential to generate new functional brain cells including neurons. The recruitment of NSCs for repair poses multiple challenges. In the adult brain, NSCs are largely quiescent and divide only infrequently. Although their proliferation increases in e.g. injury or stroke, the number of newly generated cells appears to be insufficient to compensate for the cell loss. A better understanding of the regulation of NSC quiescence and proliferation is necessary for the development of therapeutic strategies that aim at the mobilization of NSCs for repair. In the adult hippocampus, quiescent NSCs are constantly recruited into proliferation to generate new neurons. In the proposed project we will exploit this model system to characterize the molecular control of NSC quiescence and proliferation. Our preliminary data has identified PI3-kinase signalling as a candidate pathway in this process. Using a combinatio n of molecular and cell biology, genetics, and pharmacology, we will examine the role of PI3-kinase signalling in the control of the proliferate activity of NSCs. In addition, we will use transcriptome and proteome analysis to identify downstream targets of PI3-kinase signalling in quiescent and proliferating NSCs. These studies will contribute to the understanding of basic NSC biology and will identify new candidate drug targets for NSC-based therapies.
