Gene Therapy for Chronic Neurodegenerative Disorders
Major Goals: We will test the hypothesis that long term expression of Glial Derived Neurotrophic Factor (GDNF) from a gutless adenovirus vector and under the control of an inducible promoter, will be stable, non-toxic, non-immunogenic and it will not elicit adverse behavioural or neuroanatomical side effects.

National Institutes of Health/#1 R01 NS42893 01
Gene Therapy for Neurological Diseases
Major Goals: To develop novel high-capacity adenoviral systems for long term, stable, non-cytotoxic, and non-immunogenic delivery of neuro-protective genes to the brain for both experimental transgene expression in adult animals, and for the future treatment of chronic neurodegenerative diseases such as PD and Alzheimers's disease by gene therapy.

Jonsson Comprehensive Cancer Center/UCLA
Brain Tumor Stem Cells
Major goals: Cancer stem cells are self-renewing, multipotent, and capable, on a clonal level, of producing an entire, heterogeneous tumor mass. It has been theorized that curative cancer therapies will need to specifically attack these cancer stem cells. The current proposal examines the relationship between brain tumor progenitors and neural stem cells and is designed test the hypotheses that brain tumors contain cancer stem cells and that therapies directed towards blocking cancer stem cell self renewal will be effective treatments in animal models.

National Institutes of Health T32 Training Grant/UCLA
Interdisciplinary training in Virology and Gene Therapy
Major Goals: Developments in virology have led to the advancement of several disciplines, including gene therapy. The key issue in gene therapy is the development of delivery vehicles. To fulfil the national need, the UCLA Virology and Gene Training Program aims to provide a unique and outstanding environment for pre-doctoral students pursuing research careers in fields related to gene therapy. At UCLA, this rigorous training program with emphasis on vertical integration of basic sciences and therapeutic applications will produce scientists required for long-term development of gene therapy.

Training Program in Endocrinology and Diabetes
Major Goals: To provide a unique and outstanding environment for post-doctoral students pursuing research careers in fields related to endocrinology, neuro-endocrinology and metabolism at Cedars Sinai Medical Center/UCLA. This rigorous training program with emphasis on vertical integration of basic sciences and therapeutic applications will produce scientists required for long-term development of the endocrinology and diabetes field.

National Institutes of Health
Gene Therapy for neurological diseases
(Minority research supplement)
Major goal: To develop in vivo imaging techniques to assess therapeutic efficacy in pre-clinical models of neurodegeneration. Clinical platforms for imaging of PD patients.
Dr. P.R. Lowenstein, Principal Investigator

Multiple Sclerosis Society of Canada Major goals: Beside the loss of oligodendricytes and myelin, there is now extensive evidence that axonal and neuronal destruction is a common pathological feature in neuroinflammatory diseases such as Multiple Sclerosis and may account for the progressive disability that occurs in the disease. By creating neuron specific transgenic mice, we will be able to study the immune response against neurons as well as for the glial cells in the central and peripheral nervous systems. Gene therapy vectors will be used for neuronal targeting for neuromodulation and therapy. This study provides novel avenues to regulate neuroimmune interactions in brain diseases such as multiple sclerosis, or during the implementation of novel gene therapies in the brain.
