Thrombospondin-2
THBS2proteinThrombospondin-2 regulates post-infarction myocardial remodeling and fibrosis, a secondary repair process distinct from atherothrombosis.
Pathway placement
Cascade stepOff-pathway / systemic markers
Confidencemedium
RationalePost-MI remodeling mediator; acts on cardiac repair rather than the acute atherothrombotic cascade.
Also acts inVascular inflammation, Cap degradation / rupture
Druggability
Not assessed (no mapped human gene target).
Type I vs Type II discrimination
ScoresLow-confidence (proxy)
R — rupture / Type-I39
C — confounder / Type-II53
A — assay feasibility68
E — evidence strength21
T1DI (composite)6
Specificity differential (R−C)-13.5
Confounder panel (Type-II drivers)
No confounder evidence retrieved.
Tier: light (literature co-occurrence proxy — lower confidence). See the discrimination table for all markers.
Assay & specimen
Class-level default (no specific cleared assay)— generic method inferred from analyte class; confirm against a specific product insert before use.

Method / principle
Sandwich immunoassay (ELISA) — research-grade unless a cleared assay exists
Reagent / substrate
Matched anti-target antibody pair (capture + labeled detection)
Platform
ELISA microplate or multiplex (Luminex/MSD)
Turnaround · availability
