This Funding Opportunity Announcement (FOA) supports mechanistic and early translational research focused on a more rigorous in-depth examination of the potential interactions of environmental toxins with genetic and non-genetic molecular targets known to influence Alzheimer's Disease and Alzheimer's Disease Related Dementias (AD/ADRD). It is expected that these studies will address the clinical relevance of these exposures on disease initiation, progression, or modification. Anticipated outcomes include an improved understanding of neurological mechanisms of chemical toxicities related to AD/ADRD, more evidence-based potential biomarkers of exposure and toxicity for those most at risk, as well as more data to support causality and potential approaches for mitigation. The scope of research includes mechanistic studies on the modification of known AD/ADRD targets by neurotoxins of concern, and conversely, whether known targets for these neurotoxins play a role in etiologies of AD/ADRD. The development and validation of neuropathological, neurophysiological and neurobehavioral animal models that simulate potential toxin exposures in humans is another example of supported studies. Preclinical studies of interactions of environmental toxicant with AD/ADRD in pilot human subject studies (that do not meet the NIH definition of clinical trial) are appropriate for this FOA. Interdisciplinary collaboration is required to address the various fields of study related to this research, e.g., neuroscience, aging, and environmental health sciences.
