Elderberry and DHA Show Different Brain-Protein Changes in Aging Mice
This study looked at how elderberry extract and DHA (an omega-3 fatty acid) affect brain proteins and behavior in older mice. Researchers fed 44-week-old mice one of four diets — control, elderberry, DHA, or both combined — for 12 weeks, then tested memory, anxiety-like behavior, and analyzed brain tissue in detail.
Both elderberry and DHA changed patterns of proteins involved in synapse function, communication between brain cells, and a process linked to memory formation called long-term potentiation. However, they worked through different pathways: elderberry was linked to changes in a signaling pathway called CDK5 and to lower levels of a modified form of the tau protein, while DHA was linked to a different signaling pathway (CAMK) and shifted the balance of omega-3 to omega-6 fatty acids in the brain.
Behaviorally, elderberry-fed mice showed less anxiety-like behavior and did better at finding a target location in a maze test compared to control mice. The researchers connected these behavioral differences back to the specific protein and signaling changes they measured.
What this means for you
This is early-stage animal research, not a human clinical trial, so it can’t tell us how elderberry or DHA supplements would affect people. It does suggest that these two nutrients may support brain aging through different biological routes, which is a useful clue for future research but not a basis for health claims.
