摘要
Peptidoglycan muropeptides, potent proinflammatory components, are amidated in Staphylococcus aureus for unknown reasons. To study whether this modification may modulate proinflammatory capacity, cytokine induction by isogenic S. aureus strains with different amidation levels and by synthetic amidated/nonamidated muramyldipeptides was evaluated. However, amidation did not significantly affect cytokine induction. This finding contributes to defining peptidoglycan receptor specificities and indicates that further rationales for muropeptide amidation have to be considered.
