The Claim

Oxidized eicosapentaenoic acid (EPA) activates peroxisome proliferator-activated receptor alpha (PPARα) in human endothelial cells with greater potency than native EPA, and this activation is necessary for the inhibition of leukocyte adhesion in vivo, as demonstrated by loss of effect in PPARα-deficient mice.

Source: Oxidized omega-3 fatty acids in fish oil inhibit leukocyte-endothelial interactions through activation of PPAR alpha.

How it works
1 study reviewed
In plain English

Oxidized EPA activates PPARα in human blood vessel cells more strongly than regular EPA, and this activation is required to reduce white blood cell sticking to blood vessel walls in living organisms, as shown by the absence of this effect in mice lacking PPARα.

See the scientific wording

Oxidized eicosapentaenoic acid (EPA) activates peroxisome proliferator-activated receptor alpha (PPARα) in human endothelial cells with greater potency than native EPA, and this activation is necessary for its inhibition of leukocyte adhesion in vivo, as demonstrated by loss of effect in PPARα-deficient mice.

Why this might work

When EPA is oxidized, it enters endothelial cells and turns on a protein called PPARα, which shuts down a signaling pathway that would otherwise make the cells sticky. This stops the cells from producing proteins that attract white blood cells, so the white blood cells cannot stick to the vessel walls.

  1. Study: Oxidized omega-3 fatty acids in fish oil inhibit leukocyte-endothelial interactions through activation of PPAR alpha.

    The study used PPARα-deficient mice to show that the anti-adhesive effect of oxidized EPA was abolished in the absence of PPARα, while it remained effective in wild-type mice. This establishes a mechanistic dependency between PPARα activation and reduced leukocyte adhesion.
