Figure 4From: Chemokines are secreted by monocytes following OK-432 (lyophilized Streptococcus pyogenes) stimulationChemokine production follows OK-432, LTA or LPS in vitro stimulation of WB. Human WB was stimulated in parallel with OK-432 (0.01 KE/ml), LTA (0.5 μg/ml), LPS (1 μg/ml), or left unstimulated for 24 h. Supernatants were then collected and analyzed using Multiplex (MIP) or ELISA (MCP-1). Control, OK-432, LPS: n = 8; LTA: n = 4.Back to article page
