Levels of IL-6 and MCP-1 in the supernatants of 24 hours, in vitro endotoxin (1 μg/ml LPS)- stimulated purified monocytes cultures from dead versus live patients with observations at least 5 years following inclusion. Cultures were either supplied with autologous serum (AS) or serum free medium (SFM). The bars represent means ± SEM of supernatant level. (LPS-stimulated – baseline levels: IL-6 SFM/AS & MCP-1 SFM. Baseline – LPS-stimulated: MCP-1 AS). Statistics by students' t-test.
