This funding opportunity announcement (FOA) invites research to develop, characterize, and validate new, unconventional, or innovative non-rodent mammalian models of late-onset (sporadic) Alzheimer's Disease (AD). These new models are expected torecapitulate molecular, cellular, neuropathological, behavioral, and/or cognitive hallmarks and aspects of late-onset AD.Research supported under this FOA is expected to provide new investigativetools to identify the gaps in current knowledge related to molecular mechanisms of late-onset AD and identify potential therapeutic targets.
