Triglyceride-rich lipoprotein
lipoproteinTriglyceride-rich lipoprotein accumulation in subendothelium initiates lipid oxidation and atherogenic inflammation driving atherothrombotic MI.
Pathway placement
Cascade stepLipid retention & oxidation
Confidencehigh
RationaleCausal atherogenic remnant particles; promote atherosclerosis and vascular toxicity via subendothelial retention.
Also acts inVascular inflammation
Druggability

Type I vs non-Type I discrimination
ScoresLow-confidence (proxy)

Specificity differential (R−C)-11.3
Non-Type-I axis panel
Does this marker also move in each non-Type-I setting? mag 0–3; higher means less Type-I-specific. n/a = no evidence retrieved, which is not the same as no change.
No non-Type-I axis evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
