← Human Body & HealthDuring acute inflammation, why does activated NF-κB contribute to inflammation resolution, despite initially promoting pro-inflammatory cytokine production?
A)Inhibiting neutrophil chemotaxis directly
B)Suppressing COX-2 prostaglandin synthesis alone
C)Activating pro-resolution lipid mediator synthesis✓
D)Enhancing macrophage apoptosis exclusively
💡 Explanation
NF-κB activation induces not only pro-inflammatory responses but also the expression of genes that promote resolution via lipoxins and resolvins. It does this because these lipid mediators actively terminate inflammation. Therefore, activating pro-resolution lipid synthesis explains NF-κB's role, rather than solely promoting apoptosis or inhibiting neutrophil chemotaxis.
