This study aimed to investigate the anti-inflammatory, antioxidant, and antimicrobial effects of P223 which is known to have probiotic properties. P223 that had been killed by heat in LPS-induced RAW 264.7 cells decreased nitric oxide (NO) production. Furthermore, it inhibited the expression of proinflammatory cytokines such interleukin (IL)-1β, IL-6, and tumor necrosis factor-alpha (TNF-α). Heat-killed P223 also inhibited the expression of the nuclear factor (NF)-κB cellular signaling pathway, and it showed reactive oxygen species (ROS) reduction. In DPPH, ABTS, and SOD assay, P223 showed a high antioxidant capacity, and inhibited the growth of skin related pathogens including and . This study therefore demonstrated the various functional properties of P223 as probiotics, and suggested the potential for its application as functional material.
本研究旨在探究已知具有益生菌特性的P223的抗炎、抗氧化和抗菌作用。在脂多糖诱导的RAW 264.7细胞中,经热灭活的P223可降低一氧化氮(NO)的产生。此外,它还抑制促炎细胞因子如白细胞介素(IL)-1β、IL-6和肿瘤坏死因子-α(TNF-α)的表达。热灭活的P223还抑制核因子(NF)-κB细胞信号通路的表达,并显示出活性氧(ROS)的减少。在DPPH、ABTS和超氧化物歧化酶(SOD)测定中,P223表现出较高的抗氧化能力,并抑制包括……和……在内的皮肤相关病原体的生长。因此,本研究证明了P223作为益生菌的各种功能特性,并表明了其作为功能材料应用的潜力。
