Feedback Amplification Between Retrotransposons/Endogenous Retroviruses and TDP-43 in Alzheimer's Related Dementias - Project Abstract

This proposal investigates a novel idea to explain how TDP-43 protein pathology is amplified and spread between glia and neurons after initiation of disease. TDP-43 aggregation pathology is a core feature of a suite of neurodegenerative disorders including frontotemporal dementia, Alzheimer's, and amyotrophic lateral sclerosis.

We propose and will test the hypothesis that retrotransposons and endogenous retroviruses are both activated by TDP-43 pathology and can be upstream initiators of such pathology. We also will test the idea that these mobile elements contribute a mechanism of inter-cellular spread that could underlie progression of disease.

We will use both Drosophila models and mammalian cell culture to test the core features of this proposed model.

TO ENCOURAGE BIOMEDICAL, SOCIAL, AND BEHAVIORAL RESEARCH AND RESEARCH TRAINING DIRECTED TOWARD GREATER UNDERSTANDING OF THE AGING PROCESS AND THE DISEASES, SPECIAL PROBLEMS, AND NEEDS OF PEOPLE AS THEY AGE. THE NATIONAL INSTITUTE ON AGING HAS ESTABLISHED PROGRAMS TO PURSUE THESE GOALS. THE DIVISION OF AGING BIOLOGY EMPHASIZES UNDERSTANDING THE BASIC BIOLOGICAL PROCESSES OF AGING. THE DIVISION OF GERIATRICS AND CLINICAL GERONTOLOGY SUPPORTS RESEARCH TO IMPROVE THE ABILITIES OF HEALTH CARE PRACTITIONERS TO RESPOND TO THE DISEASES AND OTHER CLINICAL PROBLEMS OF OLDER PEOPLE. THE DIVISION OF BEHAVIORAL AND SOCIAL RESEARCH SUPPORTS RESEARCH THAT WILL LEAD TO GREATER UNDERSTANDING OF THE SOCIAL, CULTURAL, ECONOMIC AND PSYCHOLOGICAL FACTORS THAT AFFECT BOTH THE PROCESS OF GROWING OLD AND THE PLACE OF OLDER PEOPLE IN SOCIETY. THE DIVISION OF NEUROSCIENCE FOSTERS RESEARCH CONCERNED WITH THE AGE-RELATED CHANGES IN THE NERVOUS SYSTEM AS WELL AS THE RELATED SENSORY, PERCEPTUAL, AND COGNITIVE PROCESSES ASSOCIATED WITH AGING AND HAS A SPECIAL EMPHASIS ON ALZHEIMER'S DISEASE.
