Cytometric bead array did not show significant elevation in IL-1α, IL-1β or IL-10 protein concentration in the brain after LPS administration or anaphylaxis (data not shown), but revealed a significant increase in MCP-1 (6 fold), RANTES (3-4 fold), G-CSF (17 fold) and IL-6 (9 fold) levels in response to LPS (Figure 5B). This evidence concerns the gene IL1B and anaphylaxis.
