| Description | Loxoribine (RWJ 21757) is a guanosine analog. Loxoribine is an orally bioavailable and selective Toll-like receptor (TLR) 7 agonist. It has anti-viral and anti-tumor activities.Loxoribine is a potent new immunostimulant with a relatively broad spectrum of immunobiological activities. |
| In vitro | Loxoribine selectively activates innate immune system cells through the Toll-like receptor (TLR) 7/MyD88-dependent signaling pathway[1], leading to the maturation of human monocyte-derived dendritic cells (DCs) and enhancing their Th-1- and Th-17-polarizing capability[2]. Additionally, loxoribine (250 μM; 48 hours) promotes MoDCs maturation, evident from the increased expression of CD80, CD83, CD40, CD54, and CCR7[2]. |
| In vivo | In vivo, Loxoribine (2 mg; s.c.or i.v.) activates murine natural killer (NK) cells[3]. |
