After interaction with tracheal epithelial cells, Bordetella pertussis induces the secretion of interleukin-6. This secretion is dependent on the expression of adenylate cyclase-hemolysin by the bacterium but not on the expression of other characterized bacterial toxins or adhesins. This finding confirms the important role of adenylate cyclase-hemolysin in the pathogenicity of the bacterium.
