The present study aimed to investigate the effects of ()-(-)-1-isothiocyanato-6-(methylsulfinyl)-hexane [()-6-HITC], the major isothiocyanate present in wasabi, in an model of inflammation using lipopolysaccharide-stimulated murine peritoneal macrophages. ()-6-HITC improved the immune response and mitigated oxidative stress, which involved suppression of reactive oxygen species, nitric oxide, and pro-inflammatory cytokines (IL-1β, IL-6, IL-17, IL-18, and TNF-α) production and downregulation of pro-inflammatory enzymes such as inducible nitric oxide synthase, COX-2, and mPGES-1. In addition, ()-6-HITC was able to activate the Nrf2/HO-1 axis while simultaneously inhibiting key signaling pathways, including JAK2/STAT3, mitogen-activated protein kinases, and canonical and noncanonical inflammasome pathways, orchestrating its potent immunomodulatory effects. Collectively, these findings demonstrate the potential of ()-6-HITC as a promising nutraceutical for the management of immuno-inflammatory diseases and justify the need for further validation studies.
本研究旨在利用脂多糖刺激的小鼠腹腔巨噬细胞炎症模型,研究山葵中主要异硫氰酸酯()-(-)-1-异硫氰酸酯-6-(甲基亚磺酰基)己烷[()-6-HITC]的作用。()-6-HITC改善了免疫反应并减轻了氧化应激,这涉及抑制活性氧、一氧化氮和促炎细胞因子(IL-1β、IL-6、IL-17、IL-18和TNF-α)的产生,并下调诱导型一氧化氮合酶、COX-2和mPGES-1等促炎酶。此外,()-6-HITC能够激活Nrf2/HO-1轴,同时抑制关键信号通路,包括JAK2/STAT3、丝裂原活化蛋白激酶以及经典和非经典炎性小体通路,从而发挥其强大的免疫调节作用。总的来说,这些发现证明了()-6-HITC作为一种有前途的营养保健品用于管理免疫炎症性疾病的潜力,并证明有必要进行进一步的验证研究。
