Imiquimod is a toll-like receptor-7 agonist enhancing both the innate and acquired immune response. It activates the production of numerous compounds, including IFN-α, IL-1, -6, -8, -10, -12, and TNF-α, stimulates natural killer cells and the proliferation of B-cells. It also activates Langerhans cells and promotes their migration to the regional lymph nodes. Imiquimod stimulates TH-1 cells to produce IFN-g, which in turn can activate cytotoxic T lymphocytes. These cells provide long-term immune memory, which can offer future protection against the previously encountered virus or tumor.
