lipoxin biosynthetic process
Definition
Target type: biologicalprocess
The chemical reactions and pathways resulting in the formation of a lipoxin. A lipoxin is a non-classic eicosanoid and signaling molecule that has four conjugated double bonds and is derived from arachidonic acid. [GOC:mw]
Lipoxins are specialized pro-resolving mediators (SPMs) derived from arachidonic acid through the action of lipoxygenases (LOXs). The biosynthesis of lipoxins involves a complex interplay of enzymatic reactions and cell-cell interactions. Here's a detailed description:
**1. Initial Steps:**
* **Arachidonic Acid Release:** The process begins with the release of arachidonic acid from membrane phospholipids by phospholipase A2 (PLA2) enzymes.
* **5-LOX Activity:** 5-lipoxygenase (5-LOX), an enzyme primarily found in leukocytes, acts on arachidonic acid to produce 5-hydroperoxyeicosatetraenoic acid (5-HPETE).
**2. Formation of 15-epi-Lipoxins:**
* **15-LOX Activity:** 15-lipoxygenase (15-LOX), predominantly expressed in platelets, converts 5-HPETE into 15-hydroxyeicosatetraenoic acid (15-HETE). This step can occur within the same cell as the initial 5-LOX activity.
* **Transcellular Biosynthesis:** Alternatively, 15-HETE can be produced in a different cell, such as a platelet, and transferred to a leukocyte, where it undergoes further processing.
* **LXA4 Formation:** Leukocytes possess a unique enzyme called leukotriene A4 hydrolase (LTA4H). This enzyme can act on 15-HETE to produce lipoxin A4 (LXA4).
**3. Formation of 15-epi-Lipoxins:**
* **LXA4 Conversion:** The leukocyte enzyme 5-LOX can further process LXA4, converting it into 15-epi-LXA4.
**4. Formation of Lipoxins B4 and E4:**
* **Lipoxins B4 (LXB4) and E4 (LXE4):** These lipoxins are generated from LXA4 by specific dehydrogenase enzymes.
**5. Regulation and Modulation:**
* **Cell-Cell Interactions:** The biosynthesis of lipoxins is often influenced by cell-cell interactions, including interactions between leukocytes, platelets, and endothelial cells.
* **Modulation by Other Mediators:** Other inflammatory mediators, such as leukotrienes and prostaglandins, can influence the production of lipoxins.
* **Role of Cytokines:** Cytokines like TNF-α can modulate lipoxin production, contributing to the overall inflammatory response.
**Key Features of Lipoxin Biosynthesis:**
* **Transcellular Metabolism:** Lipoxin biosynthesis often involves the participation of multiple cell types, highlighting the importance of cell-cell interactions.
* **Unique Enzymes:** The biosynthesis of lipoxins relies on specific enzymes, including 5-LOX, 15-LOX, and LTA4H, which are expressed in distinct cell types.
* **Complex Regulation:** The production of lipoxins is subject to a delicate balance of regulatory mechanisms, ensuring appropriate levels of these mediators in response to inflammation and tissue injury.'
