| Description | Imiquimod (R 837) is an immune response modifier and a toll-like receptor 7 (TLR7) agonist with antiviral and antitumor effects. It is used in the study of external genital warts, perianal warts, cancer, and COVID-19, and is commonly employed to induce psoriasis models. |
| In vivo | In animal models, imiquimod stimulates the innate immune response by increasing NK cell activity, activating macrophages to secrete cytokines and nitric oxide, and inducing proliferation and differentiation of B lymphocytes. Imiquimod stimulates the innate immune response through induction, synthesis, and release of cytokines, including interferon-a (IFN-α), interleukin (IL)-6, and tumour necrosis factor (TNF)-α[1]. |
