Fig. 6.

Expression of membrane-bound IL-1RI and IL-RII on monocyte subpopulations in PBMCs (2 × 10⁶/mL) cultured in the presence or absence of E. coli 055:B5 LPS (200 ng/mL) for 24 h (n = 150). a Percentage of CD14⁺ cells that expressed IL-1RI and IL-1RII among PBMCs cultured with or without LPS. b Absolute number of IL-1RIs and IL-1RII molecules on populations of CD14⁺ cells in PBMCs cultured with or without LPS. Data are shown as the mean and standard error of mean (M ± SEM). Arrows on the figure indicate significant difference, P < 0.05
