The National Institutes of Health (NIH) has posted a grant opportunity titled "Access and Manipulation of Brain Cell Subtypes Implicated in Aging and AD/ADRD (R61/R33 Clinical Trial Not allowed)". This grant aims to support innovative strategies that target and manipulate brain cell subtypes affected by aging, Alzheimer's Disease (AD), and AD-Related Dementias (ADRDs). The goal is to develop and utilize sophisticated tools to precisely target disease-relevant cell subtypes in aged and degenerating mammalian brains, and to monitor and manipulate these cells in vivo to address mechanistic hypotheses related to brain aging and AD/ADRD in animal models. The grant provides up to 2 years of support for pilot activities (R61 phase) and up to 3 years of support for implementation activities including hypothesis testing (R33 phase). Eligible applicants include various institutions and organizations. The deadline for applications is October 7, 2024. For more information, visit the grant opportunity website.
