Thus, plasma MCP-1 levels correlated positively with those of: (i) IFN-α2, IL-10, fractalkine, and VEGF in T2D patients with asthma; (ii) IL-6 and GRO-α in T2D patients without asthma; (iii) MDC, IP-10, GM-CSF, FGF-2, and PDGF-AA/BB in asthma only patients; and (iv) FPG and TG in non-diabetic non-asthmatic individuals. This evidence concerns the gene IL6 and asthma.
