Organ-on-Chip Project Targets the Diabetes-Dementia Link

A consortium of researchers from the University of Bath, the University of Oxford, and Johns Hopkins University has secured a grant to build a revolutionary organ-on-chip device. The platform, named GlucoBrain, will replicate the communication networks between the gut, pancreas, and brain using living human cells grown in miniature biochips.

The goal is to investigate how diabetes influences cognitive decline. By connecting separate chip modules for each organ into a multi-organ circuit, the system will track real-time signals like glucose and hormones. This allows scientists to monitor molecular communication in a way traditional animal models cannot.

This ‘body-on-chip’ approach could accelerate early-stage drug discovery and reduce the need for animal testing. Researchers hope the technology will also advance personalized medicine by testing treatments on patient-derived cells, potentially leading to more effective therapies for both metabolic and neurological diseases.
