This Project Grant award from the National Institute on Aging's (NIA) Aging Research program (CFDA 93.866) provides $630,905 to the University of Wisconsin-Madison to explore the role of the gut microbiome-derived metabolite imidazole propionate (IMP) in the progression of Alzheimer's disease (AD) and related dementias (ADRD). The central hypothesis is that IMP modulates AD and ADRD pathology by altering vascular endothelial function and blood-brain barrier permeability. The research will...
This federal Project Grant award from the National Institute on Aging (CFDA 93.866 - Aging Research) to the University of Massachusetts Medical School is focused on understanding how the gut microbiome influences neurodegeneration and protects against Alzheimer's disease. The $647,979 award, effective September 30, 2024 through August 31, 2025, will leverage the C. elegans model system to: Determine how bacterial production of vitamin B12 protects against neurodegeneration pathways. Examine...
The National Institute on Aging (NIA) awarded a $856,580 Project Grant (CFDA 93.866 - Aging Research) to the University of Massachusetts Lowell to elucidate the microbial origins of Alzheimer's disease and related dementias (AD/ADRD) in the Hispanic Community Health Study/Study of Latinos (HCHS/SOL) cohort. The project will generate longitudinal gut microbiome and serum metabolomic profiles for approximately 2,800 HCHS/SOL participants to investigate the role of the gut microbiome in AD/ADRD...
The University of South Florida received a $3,385,215 Project Grant award from the National Institute on Aging, part of the National Institutes of Health within the Department of Health and Human Services. The grant was awarded under the Aging Research program (CFDA 93.866) to fund research titled "Microbial Therapy Improves Gut Permeability to Reduce Cognitive Decline and Alzheimer's Disease." The grant will support research from August 2021 through July 2024 to study the impact of...
The University of Alabama at Birmingham (UAB) has been awarded a $1,869,019 Project Grant by the National Institute on Aging (NIA) under the Aging Research federal grant program (CFDA 93.866). The funding will support a 3-year research project to investigate the role of circadian rhythms, gut microbiome, and gut-to-brain signaling in the onset and progression of Alzheimer's disease (AD) using a Drosophila (fruit fly) model. Key objectives include determining whether depletion of gut microbiota...
This Project Grant awarded by the National Institute on Aging (NIA) under the Aging Research program (CFDA 93.866) provides $1,189,692 to Bloom Science, Inc. to develop neuroprotective engineered bacteria for treating Alzheimer's disease. The project aims to select and engineer the probiotic bacterium Akkermansia muciniphila to produce anti-inflammatory compounds like butyrate, beta-hydroxybutyrate, and ursodeoxycholic acid, with the goal of reducing neuroinflammation and disease progression...
This Project Grant award from the National Institute on Aging (CFDA 93.866 Aging Research) to the University of South Florida will support research to determine the role of gut-derived microRNAs (miRNAs) in age-related cognitive decline and Alzheimer's disease and related dementias (ADRD). The $849,904 award, effective September 30, 2024 through August 31, 2026, will fund studies to identify unique miRNA signatures in the blood of older adults with mild cognitive impairment (MCI) and dementia...
This $825,135 Project Grant award from the National Institute on Aging (CFDA 93.866 - Aging Research) will support research at the Massachusetts General Hospital to investigate the relationships between gut microbiome-related metabolites, cerebrovascular disease, Alzheimer's disease biomarkers, and cognitive impairment. The research will leverage data from the REGARDS and CARDIA longitudinal cohort studies to examine associations between gut microbiome metabolites, brain imaging markers, and the...
This federal Project Grant award from the National Institute on Aging (CFDA 93.866 - Aging Research) provides $696,896 to the University of Texas Health Science Center at Houston to conduct research on the impact of the gut microbiome on B cell-mediated neuroinflammation in cerebral amyloid angiopathy (CAA). The research aims to investigate three key hypotheses: (1) CAA induces B cell-driven inflammation in the brain; (2) CAA-induced gut dysbiosis can promote B cell-mediated neuroinflammation...
The National Institute on Aging (NIA) awarded a $3,579,235 Project Grant (CFDA 93.866 - Aging Research) to the University of Massachusetts Medical School (UMass Medical) to investigate the role of peripheral insulin resistance and inflammation in Alzheimer's disease (AD). The project aims to delineate how metabolic dysfunction-associated steatotic liver disease (MASLD) impacts AD pathogenesis, focusing on the potential causal link between age-related liver insulin resistance, inflammation, and...

The National Institute on Aging (NIA) awarded a $502,045 Project Grant (CFDA 93.866 - Aging Research) to the University of Wisconsin-Madison to test the safety and feasibility of a custom probiotic intervention among people with Alzheimer's disease (AD) dementia and preclinical AD. The study aims to evaluate secondary outcomes, such as cognitive function and plasma biomarkers, and explore potential mechanisms by which gut microbiome modulation may impact the brain in AD. The research will be conducted over a 2-year period from May 2025 to April 2027. The goal is to inform the design and participant selection for future clinical trials on the link between gut microbiome and Alzheimer's disease.
