Summary of results comparing cytokine values taken after 3 LPS injections to controls (0 h) and to the values taken at 4 and 28 h after a single injection of LPS in serum a) and brain b). Asterisk (^*) indicates the categorie(s) under which each cytokine or chemokine is grouped. All differences are relative to single injection time points. Cytokines analyzed were: G-CSF, GM-CSF, IL- 1α, IL-1β, IL-6, IL- 10, IL-13, IP-10, KC, MCP-1, MIP-1α, RANTES, and TNF- α.
