CXCL1 and infection: Transfer of S. aureus antigen-specific Th1 cells did not affect local production of the neutrophil-recruiting chemokine CXCL1 (Fig 2B), but was associated with a significant elevation in CCL5 secretion in the peritoneal cavity early in the course of infection (Fig 2C), inferring a bias towards monocyte and memory T cell recruitment.
