In Müller cells exposed to hyperglycaemia, the protein levels of MCP-1, soluble ICAM-1, CCL20, growth-regulated oncogene/cytokine-induced neutrophil chemoattractant-1 (GRO/CINC-1), VEGF and IL-6 were increased compared to normoglycaemic controls (Fig 5). This evidence concerns the gene ICAM1 and Hyperglycemia.
