Description

The National Institute of Environmental Health Sciences (NIEHS) is soliciting applications for research to enhance understanding of the gut microbiome-brain axis to improve detection, prevention, and intervention strategies for neurological diseases caused by environmental exposures. The program covers a broad range of neurological outcomes including mental health disorders and neurodegenerative diseases like Parkinson's and Alzheimer's. The goal is to develop gut-focused interventions such as probiotics, microbial biomarkers, nutritional supplements, and novel therapeutics to reduce risk, slow progression, or reverse neurological conditions. Collaborative research combining toxicology, microbiome, and neuroscience expertise is encouraged. Applications are not currently being solicited; this notice allows potential applicants time to prepare.
