To this effect, our data show (Table 2) that in diabetic patients with asthma, MCP-1 levels correlated with IFN-α2, IL-1RA, IL-10, Fractalkine/CX3CL-1, and VEGF whereas, in diabetic patients without asthma, MCP-1 levels correlated with IL-3, IL-6, IL-9, MIP-1α/CCL-3, MIP-1β/CCL-4, GRO-α/CXCL-1, and BMI. This evidence concerns the gene IL9 and asthma.
