CXCL1 and infection: The larger lesions observed in μMT mice were associated with approximately 10-fold greater numbers of bacteria recovered from the lesions 3 d after infection (p < 0.05, Figure 1B), as well as higher levels of the inflammatory chemokine CXCL-1 (p < 0.01, Figure 1C), but not IL-17A (p = 0.15, Figure 1D).
