FIG. 2.
Eap alone is responsible for the induction of cytokine expression, and a single repeat is sufficient. PHA, control mitogen; Eap purified from Newman (the wild-type S. aureus strain); pseudo-Eap purified from the mAH12 strain lacking eap; Eap purified from the complemented mAH12(pCXEap) strain; Eap19, recombinant double repeat of Eap; and Eap10, recombinant single repeat of Eap.
