We measured concentrations of cytokines and soluble receptors from plasma ( interleukin-@ receptor agonist ( IL-@Ra ) , IL-@ , IL-@ , IL-@ , tumor necrosis factor ( TNF ) - , monocyte chemoattractant protein ( MCP ) -@ , soluble urokinase-type plasminogen activator receptor ) , and secreted cytokines ( interferon - , TNF - , IL-@ , IL-@ , IL-@ , IL-@ ) after in vitro challenge with innate agonists and recall antigens .
