CXCL1 and infection: In the mutant strain infection, we noted that Th17-related cytokines (IL-17A, IL-22) and neutrophil-related chemokines (CCL2, CCL3, CXCL1, CXCL2) are significantly reduced at the early stage of infection, which might be related to the absence of melanin and defects in growth and germination.
