The chemokines, MCP-1, MIG (CXCL9) and MIP-1α, and the growth factor, FGF, which have been implicated in the inflammation and increased angiogenesis associated with remodelling in asthma (Linden, 2003; Kolls and Linden, 2004; Havaux et al., 2005; Bosse et al., 2006; Feltis et al., 2006) were detected; however, serum levels of these inflammatory mediators were not found to be significantly different amongst the four treatment groups (results not shown). Here, CCL2 is linked to asthma.
