Both GRO/KC and MCP-1 protein levels were suppressed by XLS, as seen when comparing the two groups, DSS + XLS, and DSS + saline (155.31 ± 15.38 pg/mg protein [N = 10] versus 817.92 ± 308.07 [N = 9], P < 0.01 for GRO/KC, and 666.11 ± 45.73 pg/mg protein [N = 10] versus 2065.03 ± 316.12 [N = 9], P < 0.01 for MCP-1, resp). Here, CCL2 is linked to keratoconus.
