Maresin-1 resolution with RORα and LGR6

Area of Science:

• Lipid mediator pharmacology
• Receptor pharmacology
• Inflammation resolution biology

Background:

• Maresin-1 is a pro-resolving lipid mediator with significant pharmacological interest.
• Two distinct receptor targets for maresin-1 have been identified: RORα and LGR6.
• RORα is a nuclear receptor, while LGR6 is a plasma membrane GPCR.

Purpose of the Study:

• To review the pharmacology of maresin-1's newly identified receptor targets.
• To elucidate the roles of RORα and LGR6 in maresin-1's pro-resolving functions.
• To explore maresin-1's impact on inflammation resolution, host defense, tissue homeostasis, and wound healing.

Main Methods:

• Pharmacological review of maresin-1 and its identified receptors.
• Analysis of intracellular signaling pathways involved in maresin-1 resolution.
• Literature synthesis on the functions of RORα and LGR6 in biological processes.

Main Results:

• Maresin-1 interacts with both retinoic acid-related orphan receptor α (RORα) and leucine-rich repeat domain-containing G protein-coupled receptor 6 (LGR6).
• The distinct cellular localizations (nuclear vs. plasma membrane) of RORα and LGR6 suggest diverse signaling mechanisms.
• The identification of these dual targets opens avenues for understanding maresin-1's multifaceted roles.

Conclusions:

• Understanding maresin-1's interaction with RORα and LGR6 is crucial for its therapeutic potential.
• Further research into the specific functions mediated by each receptor will clarify maresin-1's role in health and disease.
• This review highlights the expanding pharmacological landscape of maresin-1 and its implications for resolution biology.
