ABSTRACT
In response to bacterial infection, airway epithelium releases inflammatory mediators including cytokines and chemokines that lead to immune cell efflux and could stimulate the adaptive T cell immune response. The aim of our study was to analyze, in a double chamber culture, the chemokine changes in response to Staphylococcus aureus and their consequences for T cells. Our data show that S. aureus stimulates basolateral and apical release of IL-8 and eotaxin by airway epithelial cells. We also observed increased chemokine receptor expression on CD8+ and CD4+ T cells and enhanced chemotaxis of CD4+ T cells toward apical supernatant. Our data strongly suggest that S. aureus interaction with airway epithelium contributes to specific migration of T cells to inflamed sites.
