Representative expression of IL-6 and TNF in LPS-stimulated CD14+ cells from a participant at baseline and at PSD. Numbers indicate percentage of the fraction of CD14+ cells that are positive for TNF alone (upper left), TNF and IL-6 (upper right), and IL-6 alone (lower right). In the baseline condition, 72.1% of the CD14+ cells are negative for both IL-6 and TNF, whereas only 34.5% of the CD14+ cells are negative for both IL-6 and TNF in the PSD condition.
