FIG. 1.

Production of cytokines involved in the inflammatory reaction after stimulation with LPS and PHA. PBMCs from patient (hatched bars) and control subjects (gray bars) were cultured in the presence of PHA or LPS for 48 h. The cytokine levels in the supernatants (in picograms per milliliter) were determined by ELISA. Horizontal lines represent median values, boxes represent 25th to 75th percentiles, and vertical lines represent 10th to 90th percentiles. Statistical significance between groups is indicated (*, P < 0.05, Mann-Whitney test).
