TLR7 Agonist 852A

**Semantic type:** Organic Chemical|Pharmacologic Substance

**Definition:** A synthetic imidazoquinoline Toll-like receptor 7 (TLR7) agonist with immunostimulating and potential antitumor activities. TLR7 agonist 852A binds to and activates TLR7, thereby stimulating plasmacytoid dendritic cells (pDC) through the TLR7-MyD88-dependent signaling pathway. Activation of pDC results in secretion of interferon alpha, the production of proimflammatory cytokines, the upregulation of co-stimulatory molecules, and enhanced T and B-cell stimulatory responses.
