Reactive oxygen species
Pathway / Plaque inflammation

Reactive oxygen species

metabolite

Reactive oxygen species generated during plaque inflammation oxidize lipids, activate platelets, and cause vascular dysfunction in Type 1 MI.

Pathway placement
Cascade stepPlaque inflammation
Confidencehigh
RationaleOxidative mediator of plaque inflammation and atherosclerosis; drives lipid oxidation and platelet activation.
Also acts inLipid entry/oxidation, Platelet activation
Druggability
