Lab-Grown Neurons From a Rare Genetic Disorder Show Improved Function After DHA Exposure
Researchers grew human neurons in the lab from a person with SHINE syndrome, a rare genetic condition caused by mutations in the DLG4 gene. This gene makes a protein called PSD-95, which helps organize the connections (synapses) between brain cells.
The lab-grown neurons from this patient showed lower PSD-95 levels, abnormal branching, and disrupted electrical activity patterns compared to typical neurons, including weaker firing, altered burst patterns, and less coordinated network activity.
When the researchers exposed these neurons to the omega-3 fatty acid DHA, PSD-95 protein levels increased and several measures of network activity improved. The cells also showed early signs of increased activity in two signaling pathways (ERK and CREB) that are involved in synapse health, though these changes were described as trends rather than definitive results.
What this means for you
This is early-stage laboratory research using neurons grown from a single patient with a rare genetic disorder—not a human clinical trial. It offers an interesting biological clue about how DHA might interact with synapse-related proteins, but it does not show that DHA treats, prevents, or cures any condition. Much more research would be needed before drawing conclusions relevant to general omega-3 supplementation.
