Signal Transducer and Activator of Transcription 3

STAT3protein

STAT3 activation by IL-10 restrains macrophage-driven plaque inflammation and vascular endothelial activation, reducing atherosclerotic destabilization.

Pathway placement
Cascade stepPlaque inflammation
Confidencehigh
RationaleIL-10 responsive transcription factor; anti-inflammatory pathway regulator; suppresses plaque inflammation and endothelial dysfunction.
