Following a severe bacterial infection in lung tissue, what explains the crucial role of lipoxins and resolvins in facilitating the resolution of inflammation, rather than its chronic persistence?

💡 Explanation

Lipoxins and resolvins are lipid mediators that actively promote the resolution of inflammation by reprogramming macrophages to a pro-resolution phenotype; because they initiate the resolution phase, this terminates the inflammatory response. Therefore, specific macrophage activation leads to clearance rather than continued inflammation, rather than the other options that perpetuate inflammation.
