**Core Concept**
Lipoxins are anti-inflammatory mediators derived from arachidonic acid through the action of 15-lipoxygenase and 5-lipoxygenase enzymes. They play a crucial role in resolving inflammation by promoting the clearance of inflammatory cells and mediators.

**Why the Correct Answer is Right**
Lipoxins act by binding to specific receptors, such as the formyl peptide receptor-like 1 (FPRL1), which triggers a signaling cascade that leads to the inhibition of inflammatory responses. This involves the activation of protein kinase C (PKC) and the subsequent phosphorylation and activation of various proteins that contribute to the resolution of inflammation. Lipoxins also promote the production of anti-inflammatory cytokines, such as IL-10, and inhibit the production of pro-inflammatory cytokines, such as TNF-alpha.

**Why Each Wrong Option is Incorrect**
* **Option A:** Incorrect because lipoxins are not primarily involved in the initiation of inflammation.
* **Option B:** Incorrect because lipoxins do not act by stimulating the production of pro-inflammatory cytokines.
* **Option C:** Incorrect because lipoxins do not primarily act by inhibiting the action of cyclooxygenase enzymes.

**Clinical Pearl / High-Yield Fact**
Lipoxins are an important class of anti-inflammatory mediators that play a crucial role in resolving inflammation and promoting tissue repair. Understanding the mechanisms of lipoxins can provide valuable insights into the development of new therapeutic strategies for treating inflammatory diseases.

**Correct Answer:** D.
