Target	TLR7[1]
In Vitro	Loxoribine induces maturation of human monocyte-derived dendritic cells DCs and stimulates their Th-1- and Th-17-polarizing capability[2]. Loxoribine (250 μM; 48 hours) stimulates maturation of MoDCs as shown by up-regulation of CD80, CD83, CD40, CD54 and CCR7[2]. loxoribine activates cells of the innate immune system selectively via the Toll-like receptor (TLR) 7/MyD88-dependent signaling pathway[1].
In Vivo	Loxoribine (2 mg; s.c.or i.v.) activates murine natural killer (NK) cells in vivo[3]. Animal Model: 8-12 weeks male CBA/J mice[3] Dosage: 2 mg Administration: Subcutaneous or intravenous injection Result: activates murine natural killer (NK) cells in vivo.
