Randomized trial investigates NF-κB's role in atherosclerosis, revealing impaired macrophage function increases disease severity.

This research explores how inhibiting NF-kappaB in macrophages affects atherosclerosis progression in LDL receptor-deficient mice.
Used LDL receptor-deficient mice with macrophage-restricted IkappaB kinase 2 deletion to study NF-kappaB activation role.
Measured atherosclerosis lesion areas and quantified necrosis and cell count in lesions.
Examined macrophage responses to LPS stimulation, focusing on cytokine production.
Inhibition of IKK2 led to increased atherosclerosis, evidenced by larger lesion area and more advanced lesions.
NF-kappaB activation in macrophages was reduced by approximately 50% in IKK2-deleted mice.
Production of TNF was decreased by about 50% and anti-inflammatory IL-10 was significantly reduced in IKK2-deleted macrophages.

Kanters et al. (2003) studied this question.
