Abstract

Resolution of inflammation is an active process mediated by pro-resolution lipid mediators. As resolvin (Rv) D1 is produced in the cornea, pro-resolution mediators could be effective in regulating inflammatory responses to histamine in allergic conjunctivitis. Two key mediators of resolution are the D-series resolvins RvD1 or aspirin-triggered RvD1 (AT-RvD1). We used cultured conjunctival goblet cells to determine whether histamine actions can be terminated during allergic responses. We found cross-talk between two types of G protein-coupled receptors (GPRs), as RvD1 interacts with its receptor GPR32 to block histamine-stimulated H1 receptor increases in intracellular [Ca(2+)] ([Ca(2+)]i) preventing H1 receptor-mediated responses. In human and rat conjunctival goblet cells, RvD1 and AT-RvD1 each block histamine-stimulated secretion by preventing its increase in [Ca(2+)]i and activation of extracellular regulated-protein kinase (ERK)1/2. We suggest that D-series resolvins regulate histamine responses in the eye and offer new treatment approaches for allergic conjunctivitis or other histamine-dependent pathologies.
