This study shows that most known mediators of immunity, such as TLR2, MyD88, T cells or B cells, and neutrophils and monocytes, are dispensable for pain produced by Staphylococcus aureus infection; instead, bacterial products, such as N-formylated peptides and α-haemolysin, induce pain by directly activating nociceptor neurons, which in turn modulate inflammation.
