Signaling Pathways Used by the Specialized Pro-Resolving Mediator Maresin 2 Regulate Goblet Cell Function: Comparison with Maresin 1
Specialized pro-resolving mediators (SPMs), including Maresins (MaR)-1 and 2, contribute to tear film homeostasis and resolve conjunctival inflammation. We investigated MaR2′s signaling pathways in goblet cells (GC) from rat conjunctiva. Agonist-induced [Ca<sup>2+</sup>]<sub>i</...

| description | Specialized pro-resolving mediators (SPMs), including Maresins (MaR)-1 and 2, contribute to tear film homeostasis and resolve conjunctival inflammation. We investigated MaR2′s signaling pathways in goblet cells (GC) from rat conjunctiva. Agonist-induced [Ca<sup>2+</sup>]<sub>i</sub> and high-molecular weight glycoconjugate secretion were measured. MaR2 increased [Ca<sup>2+</sup>]<sub>i</sub> and stimulated secretion. MaR2 and MaR1 stimulate conjunctival goblet cell function, especially secretion, by activating different but overlapping GPCR and signaling pathways, and furthermore counter-regulate histamine stimulated increase in [Ca<sup>2+</sup>]<sub>i</sub>. Thus, MaR2 and MaR1 play a role in maintaining the ocular surface and tear film homeostasis in health and disease. As MaR2 and MaR1 modulate conjunctival goblet cell function, they each may have potential as novel, but differing, options for the treatment of ocular surface inflammatory diseases including allergic conjunctivitis and dry eye disease. We conclude that in conjunctival GC MaR2 and MaR1, both increase the [Ca<sup>2+</sup>]<sub>i</sub> and stimulate secretion to maintain homeostasis by using one set of different, but overlapping, signaling pathways to increase [Ca<sup>2+</sup>]<sub>i</sub> and another set to stimulate secretion. MaR2 also resolves ocular allergy. |
