Implication

E-LDL may promote SMC-driven atherogenesis; leaves open whether this pathway is clinically targetable.

Key Points

This research examines how enzymatically degraded, nonoxidized LDL (E-LDL) affects human vascular smooth muscle cells.
Analyzed the accumulation of E-LDL in human vascular smooth muscle cells.
Examined the expression of inflammatory mediators and the signaling pathways involved.
Studied the autocrine and transsignaling mechanisms that lead to cell proliferation.
E-LDL accumulation in vascular smooth muscle cells led to increased expression of monocyte chemotactic protein-1.
The secretion of IL-6 was significantly stimulated, indicating activation of the IL-6 receptor pathway.
Macrophage supernatants prompted sustained proliferation in SMCs through E-LDL induced pathways.
