Immunoglobulin A
Pathway / Plaque inflammation

Immunoglobulin A

protein

IgA levels reflect adaptive immune activation in plaque inflammation and are altered post-MI.

Pathway placement
Cascade stepPlaque inflammation
Confidencemedium
RationaleImmune response marker in atherosclerosis; reduced post-MI reflects systemic immune perturbation.
Druggability
Not assessed (no mapped human gene target).

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.
