CCL4 and infection: We found again the same time-dependent variations as for C57BL/6 J mice (Fig. 6C): as in the 4 CT experiment (Fig. 6B), Mip2, Mip1α and Mip1β showed higher expression upon infection at CT15 than at CT3, Mcp1 had similar level of expression for both time points, and Tnfα had a slightly (but not significantly) higher response to infection at CT15.
