Lipids play a preeminent role in inflammation.

Insights in the Role of Lipids, Oxidative Stress and Inflammation in Rheumatoid Arthritis Unveiled by New Trends in Lipidomic Investigations, 2021
Interestingly, aspirin does not simply inhibit COX-2, but rather diverts its enzymatic activity toward the synthesis of precursors of lipoxin A4
The first step of Lipoxin A4 synthesis is shared by leukotrienes synthesis, is catalyzed by 5-LOX, and leads to LTA-4 synthesis.
Aspirin-triggered lipoxin in patients treated with aspirin and selective vs. nonselective COX-2 inhibitors. 2010
Cyclooxygenase (COX)-2 inhibition has been reported to suppress the biosynthesis of the gastroprotective lipoxygenase metabolite 15®-epi-lipoxin A4, also termed ‘aspirin-triggered lipoxin’ (ATL)
Aspirin-triggered lipoxin induces CB1-dependent catalepsy in mice. 2010
Aspirin, a non-selective COX inhibitor, acetylates COX-2 with generation of a lipoxygenase (LOX) substrate, whose end product is the 15-epi-lipoxin A(4) (15-epi-LXA), an aspirin-triggered lipoxin.
Lipoxin-Mediated Inflammatory Resolution in Newborn Hyperoxic Lung Injury
Aspirin, an anti-inflammatory drug that acetylates COX-2 and changes COX-2 function from a cyclooxygenases to a lipoxygenase, generates a more biologically stable and potent form of lipoxins, 15-epi lipoxins.
Cyclooxygenase 2 plays a pivotal role in the resolution of acute lung injury. 2005
COX-2-derived products increased levels of the pro-resolving lipid mediators lipoxin A4 (LXA4) and, in the presence of aspirin, 15-epi-LXA4.
Lipidomic and Transcriptome Signatures in Aspirin-Exacerbated Respiratory Disease 2009
When individuals with AERD ingest aspirin or other inhibitors of cyclooxygenase 1 they develop acute worsening of their rhinosinusitis accompanied by acute bronchoconstriction that may be life-threatening.
Induction of COX-2 by glucocorticoids + aspirin is the best anti-inflammatory combination? Dosage?
