The Role of Apolipoprotein E, Lipoprotein Receptors and CNS Lipid Homeostasis in Brain Aging and Alzheimers Disease (R01)

archived

Purpose. This FOA encouarges multidisciplinary and interdisciplinary research to elucidate how Apolipoprotein E, lipoprotein receptors and CNS lipid homeostasis influence brain aging and the transition to neurodegeneration in Alzheimers disease (AD). The ultimate goal is to gain an in depth understanding of the mechanisms by which the Apolipoprotein E e4 allele confers increased AD risk for the purpose of advancing the overall search for efficacious AD treatments and Apolipoprotein E e4-directed therapeutics in particular. To this end we encourage research spanning multiple levels of analysis in multiple species (from mice to man).Studies aimed at identifying new therapeutic targets for the treatment of AD and other age-related neurodegenerative conditions associated with lipid neurobiology are strongly encouraged. Also of great interest are projects that aim to use lipidomics, various types of imaging and other cutting edge technologies to identify and develop early biomarkers of neurodegeneration associated lipid dyshomeostasis. Mechanism of Support. This FOA will utilize the R01 grant mechanism. Funds Available and Anticipated Number of Awards. During Fiscal Year 2010, the estimated amount of funds available to support projects under this FOA is $2,500,000.Because the nature and scope of the proposed research will vary from application to application, it is anticipated that the size and duration of each award will also vary.Given the likely range of budgets, it is anticipated that 4 to 7 awards could be made during Fiscal Year 2010.The availability of funds and the number of awards in future years will depend upon annual appropriations.
