Toll-like receptor (TLR) 7/8 agonists have been applied in combination with chemo-, radio- or immunotherapy for lymphoma, and used as topical drugs for the treatment of viral skin lesions and skin tumors. In the present study, the role of an adenine analog, 9-(4-carboxyphenyl)-8-hydroxy-2-(2-methoxyethoxy)-adenine [termed Gao Dong (GD)], a novel TLR7 agonist, in the activation of cytokine-induced killer/natural killer (CIK/NK) cells was determined. The results of the present study indicated that GD was able to activate CIK/NK cells. The proportion of GD-induced CD3+CD56+ CIK and CD3?CD56+ NK cells was ~4% higher respectively compared with the control. Notably, combination therapy with CIK/NK cells stimulated by GD, markedly suppressed the proliferation of the chronic myelogenous leukemia K562 cell line. Following GD treatment, the cytotoxicity improved by ~25 and 21% when the effector/target ratio was 20:1 and 10:1, respectively. The results of the present study suggested a novel protocol for CIK/NK cell proliferation and revealed that GD may serve as a potent innate and adaptive immunomodulator in immunocyte culture.
