The Aging Brain Matrix: Cross-Species Evidence Linking FREM3 to Brain and Cognitive Aging
The human extracellular-matrix-related FREM3 gene is strongly age-dependent, enriched in age-sensitive excitatory long-range-projecting neurons, and implicated in neurodegenerative diseases. To establish the first translationally relevant causal evidence for the role of FREM3 in brain structure and cognition, we developed an excitatory-neuron-specific Frem3 conditional knockout mouse model…
