If a viral infection triggers excessive production of IL-1β cytokine in lung tissue, which consequence follows regarding inflammation resolution?

A)Enhanced neutrophil apoptosis occurs rapidly
B)Increased macrophage phagocytosis of debris
C)Elevated lipoxin production inhibits inflammation
D)Prostaglandin E2 synthesis sustains inflammation

💡 Explanation

Elevated IL-1β stimulates COX-2 and prostaglandin E2 (PGE2) production, sustaining inflammation, because PGE2 promotes vasodilation and immune cell recruitment. Therefore, inflammation is prolonged, rather than being resolved by neutrophil apoptosis or lipoxins, which have anti-inflammatory effects.
