Representative flow cytometric analysis of peripheral blood CD68 positive monocytes (A), M1-like CD163^−/intCD11c^high monocytes and M2-like CD163^int/hiCD11c^int monocytes (B), IL-21R⁺ monocytes and TLR4⁺ monocytes (C).

<p>The numbers represent percentage of cells within the gates. At least 10⁶ total cells were acquired followed by gating on size versus granularity followed by exclusion of dead cells and finally detection of markers described in plots.
