Project 4: Integrative analysis of spatial molecular features and clinico-pathological characteristics

['FUNDING_OTHER'] · COLUMBIA UNIVERSITY HEALTH SCIENCES · NIH-11180259

Researchers will create detailed 3-D maps of molecular and cellular changes in older adults' brains to link those changes with memory and thinking problems.

What this research studies

This project will profile brain tissue from about 300 older adults who donated their brains, using 3-D molecular mapping and single-nucleus RNA sequencing to identify cell types and protein pathologies like amyloid, tau, Lewy bodies, and TDP43. The team will combine these molecular maps with the donors' cognitive testing done before death to see which brain changes match memory and thinking decline. The work focuses on how multiple pathologies that often occur together affect cognition and on a newly described microglial cell type (Mi13) that may play a role. The resulting 3-D dataset will be shared so other researchers can use it to speed development of diagnostics and treatments.

Who could benefit from this research

Good fit: Ideal candidates are older adults (including people with Alzheimer's or related dementias) who join clinical research cohorts and agree to longitudinal cognitive testing and brain donation.

Not a fit: People who cannot or will not join longitudinal cohort studies or participate in brain donation programs are unlikely to directly take part or benefit from this specific project.

Why it matters

Potential benefit: If successful, this work could reveal biological markers and targets tied to cognitive decline that help guide future tests and treatments for Alzheimer's and related dementias.

How similar studies have performed: Large brain-tissue programs (for example ROSMAP) have already linked molecular changes to cognition, and this project builds on those successes by adding 3-D spatial detail and a more diverse sample.
