TNF-α, IL-1β, and MCP-1 in aqueous humor after GHRH-R antagonist treatment. LPS-induced elevations of TNF-α (A), IL-1β (B), and MCP-1 (C) were reduced significantly by the GHRH-R antagonist MIA-602 and Dxm but not by the GHRH-R agonist MR-409. Data are shown as mean ± SEM; **P < 0.05; ##, no significant difference compared with LPS; Mann–Whitney test; n = 6 in each group.
