Meccanismo d'azione (Mechanism of Action)

Targets/IC50/Ki
TLR7
TLR8
In vitro

Resiquimod (R-848) activates immune cells and induces proliferation of wild-type splenocytes via the Toll-like receptor 7 (TLR7)-MyD88-dependent signaling pathway.

This compound also modulates dendritic cells to augment cytomegalovirus- and HIV-1-specific T cell responses.

It induces the differentiation of myeloid-derived suppressor cells into macrophages and dendritic cells, and may improve cancer immunotherapy by reducing immunosuppressive MDSCs.

In vivo

In wild-type mice, Resiquimod (R-848) (50 nmol, i.p.) induces increased serum concentrations of IFN-alpha, TNF-alpha and IL-12, while neither TLR7-deficient mice nor MyD88-deficient mice show an increase in these cytokines.

In a murine model of allergic asthma, this compound (i.n., 20 μg/mouse) reduces allergen induced airway reactivity and inflammation via reduction in Nrf2 signaling.
