Four multimodal profiles.
We discovered 4 unique multimodal molecular profiles, one of them showing signs of poor cognitive function, a faster pace of disease progression, shorter survival with the disease, severe neurodegeneration and astrogliosis, and reduced levels of metabolomic profiles.
Knight-C4 n=42.
We identified 4 clusters ( Fig 2A ) in which the molecular profiles of Cluster4 (named Knight-C4 hereafter, n = 42) exhibited a pronounced dysregulation of genes, proteins, and metabolites.
What they did
Integrated transcriptomic, proteomic, metabolomic, and lipidomic profiles with clinical/neuropathological data using machine learning and clustered multimodal profiles.
What they found
Four profiles emerged; one severe profile had poor cognition, faster progression, shorter survival, neurodegeneration/astrogliosis, and reduced metabolomic signals. Knight-C4 (n=42) showed pronounced multi-layer dysregulation.
The limits
What it doesn't show
Clusters are observational patterns, not proven treatment-response groups.
