Pathway / Off-pathway / systemic markers

tryptophan

metabolite

Tryptophan metabolism dysregulation associates with immune dysbalance and heightened atherosclerotic inflammation in MI risk, operating through systemic pathways.

Pathway placement
Cascade stepOff-pathway / systemic markers
Confidencemedium
RationaleAmino acid metabolite with complex roles in immune regulation and systemic metabolic stress; not direct atherothrombotic pathway molecule.
