The National Institutes of Health (NIH) is offering a funding opportunity titled "Protective Strategies to Reduce Amyloid Related Imaging Abnormalities (ARIA) After Anti-Amyloid Beta Immunotherapy (R01 - Clinical Trial Not Allowed)." This initiative aims to explore the cellular and molecular mechanisms that affect the blood-brain barrier during passive anti-beta-amyloid immunotherapy, particularly in the context of Alzheimer's disease and related dementias. The program is significant for advancing the understanding of ARIA, which is crucial for improving the safety and efficacy of Alzheimer's therapeutics. Eligible applicants include various academic institutions, nonprofits, and state and local governments, with a funding ceiling of $500,000 per project per year, totaling up to $3.75 million annually for up to five projects. Interested parties must submit their applications by November 5, 2024, and can direct inquiries to grantsinfo@nih.gov or visit the opportunity's webpage for more details at https://grants.nih.gov/grants/guide/pa-files/PAR-24-198.html.
