At 3 h post infection (pi) the MCP-1 level was increased to 253% (p < 0.0001) which increased significantly at 6 h (281%, p < 0.0001), 12 h (535%, p < 0.0001) and reached to the level 794% (p < 0.0001) at 24 h post infection (Fig. 6) when compared to the level expressed at 0 h post JEV infection. Here, CCL2 is linked to infection.
