FIG. 5.

Chemokine and cytokine production in the hearts of C3H wild-type and KC^−/− mice at 11 and 21 days after infection with B. burgdorferi. Hearts were harvested at the indicated time points, and protein was extracted as described previously (10). Levels of KC (A), LIX (B), MIP-2 (C), IL-6 (D), IL-1β (E), and TNF-α (F) were quantified by ELISA. With the exception of KC there were no significant differences in any of the cytokine or chemokine levels between the C3H wild-type and KC^−/− mice at either time point.
