Toll-like receptor expression by monocytes from AAV patients who were nasal carriers of <i>S. aureus</i> (n = 13, white bars) and non-carriers (n = 25, gray bars).

<p>Both the proportions of mTLR<sup>+</sup> monocytes (left y-axis), as well as the level of mTLR expression (right y-axis) did not differ significantly between monocytes from nasal carriers and non-carriers. Intracellular levels of TLR9 (iTLR9) were increased in monocytes from patients who were nasal carriers of <i>S. aureus</i>.</p>
