Application

Resiquimod has been used in the stimulation of bone marrow-derived dendritic cells (BMDCs) stimulation( and B cells. It has also been used as a ligand for toll-like receptors (TLR7) in malignant melanoma cell line B16F10.
Resiquimod may be used in immunological and cancer-related cell signaling studies.

Biochem/physiol Actions

Resiquimod (R-848) is a potent synthetic agonist of TLR7/TLR8 that possesses antiviral and antitumoral activities.
Resiquimod belongs to the class of imidazoquinolinamines compounds with immunomodulatory effects. Resiquimod increases the levels of cytokines such as TNF-α, IL-6 and IFN-α.
Resiquimod is 314.4 Da molecule which elicits immune function during visceral infection with L. infantum Sp. It mediates the trafficking of granulocytes, macrophages, leukocytes and dendritic cells. It is a recommended topical drug for treating skin tumors like actinic keratosis (AK) and superficial basal cell carcinoma.

Long-term epigenetic reprogramming of innate immune cells in response to microbes, also termed "trained immunity," causes prolonged altered cellular functionality to protect from secondary infections. Here, we investigated whether sterile triggers of inflammation induce trained immunity and thereby influence innate
