Objective and Design: To evaluate the mechanism whereby monocyte chemoattractant protein (MCP)-1 attracts monocytes in vivo. Subjects: New Zealand white rabbits (175 rabbits) were used. Treatment: LPS, MCP-1 or IL-8 was injected into knee joints. Antibodies against various cytokines or IL-1 receptor antagonist were injected to neutralize cytokine activities. Methods: The numbers of leukocyte populations, levels of cytokines in joints were estimated. Results: Partial inhibition of neutrophil influx with anti-IL-8 IgG (10 μg) suppressed LPS-induced macrophage influx by 43 ± 8.5% (p
