Abstract

[6]-Gingerol, [8]-gingerol, and [10]-gingerol are pungent components of fresh ginger, extracts of which inhibit various components of the inflammatory response. Because little is known regarding the effect of gingerols with different unbranched alkyl side chain lengths on the activation and effector function of T lymphocytes, we compared the effects of [6]-gingerol, [8]-gingerol, and [10]-gingerol on murine T lymphocyte proliferation, expression of CD25 and CD69 activation markers, cytokine synthesis, and interleukin (IL)-2 receptor signaling. All three gingerols inhibited DNA synthesis by T lymphocytes, as well as interferon-α synthesis. In contrast, only [8]-gingerol and [10]-gingerol inhibited CD25 and CD69 expression, and IL-2 synthesis. None of the gingerols affected IL-4 synthesis. Exogenous IL-2 enhanced T lymphocyte proliferation in the presence of [6]-gingerol but did not significantly increase T lymphocyte proliferation in the presence of [8]-gingerol or [10]-gingerol. In line with this finding, [8]-gingerol and [10]-gingerol impaired IL-2-induced proliferation of CTLL-2 cells, but constitutive CD25 expression was unaffected, indicating inhibition of IL-2 receptor signaling. In general, [10]-gingerol and [8]-gingerol were more potent inhibitors of T lymphocytes than [6]-gingerol. Suppression of T lymphocyte responses by gingerols suggests that these phytochemicals may be beneficial in chronic inflammatory conditions

[8]-Gingerol and [10]-gingerol (purity > 98%) were from Chengdu Biopurify Phytochemicals Ltd. (Chengdu, Sichuan, China).
