LPS-induced pro-inflammatory cytokine productions in macrophages from WT and GHSR
mice. The primary peritoneal macrophages from WT and GHSR−/− mice were isolated and stimulated with LPS for 2 hours. The productions of pro-inflammatory cytokines, TNF (A), IL-6 (B) and IL-12 (p40) (C), were detected in the supernatants by ELISA. Each bar represents the mean ± SEM; *p < 0.05 and ***p < 0.005.
