Although splenic expression of IL-1β, MCP-1, and IL-10 was significantly lower in mice in the HF diet group compared to those in the standard chow group, in serum, only IL-10, but not IL-1β or MCP-1, was significantly lower in the HF diet group compared to the standard chow group (Table 1). The gene discussed is CCL2; the disease is hydrops fetalis.
