Why does chronic inflammation persist even when initial triggers subside, specifically concerning the prostaglandin pathway?

A)Toll-like receptors desensitize over time
B)Neutrophils exhaust cytokine production ability
C)NF-kB activation creates positive feedback loops
D)Complement cascade components degrade quickly

💡 Explanation

Chronic inflammation can persist because NF-kB activation, a key step in the prostaglandin pathway, establishes positive feedback loops amplifying its own signaling. These loops sustain inflammation even without continuous external stimuli; therefore, inflammation continues, rather than resolving due to receptor desensitization or component degradation.
