Thus, IL-10 inhibits MHC class II and costimulator

Thus, IL-10 inhibits MHC class II and costimulatory molecule B7-1/B7-2 expression on monocytes and macrophages and limits the production of proinflammatory cytokines (including IL-1α and β, IL-6, IL-12, IL-18, and TNF-α) and chemokines (MCP1, MCP5, RANTES, IL-8, IP-10, and MIP-2)
