lactosylceramide
lipidLactosylceramide regulates monocyte recruitment and inflammatory signaling, bridging lipid retention and plaque inflammation.
Pathway placement
Cascade stepPlaque inflammation
Confidencemedium
RationaleSphingolipid mediator of plaque inflammation, monocyte migration, and atherothrombotic initiation.

Type I vs non-Type I discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I26
C — non-Type-I48
A — assay feasibility40
E — evidence strength17
T1DI (composite)3
Specificity differential (R−C)-21.7
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.
