Implication

Randomized trial shows DHA modifies lipid rafts and inhibits inflammation in retinal endothelial cells, suggesting therapeutic potential.

Key Points

This research aims to investigate how docosahexaenoic acid (DHA) influences cytokine signaling in human retinal endothelial cells through alterations in lipid rafts.
Cultured human retinal vascular endothelial cells (hRVE) with and without DHA exposure.
Prepared lipid raft-enriched membrane domains using sucrose gradient ultracentrifugation and analyzed fatty acid and cholesterol content by HPLC.
Assessed Src family kinases expression via Western blotting and immunohistochemistry.
DHA incorporation into caveolae/lipid rafts increased unsaturation index and resulted in 70% cholesterol depletion from these domains.
Cytokine-induced signaling was significantly diminished by disrupting caveolae/lipid raft structure using cholesterol-depleting agent MCD.
Replenishing cholesterol reversed DHA's effects on cytokine-induced signaling in treated cells.
