摘要:
spackib fackiff: 我们先前的研究已经证明了一项牢固的研究。痤疮),氧化应激和痤疮炎症。色林酸(SA)是一种广泛用于抗菌,抗炎和抗氧化活性的植物,但缺乏痤疮数据。这项研究旨在调查SA对痤疮的影响和机制ammation induced by C. acnes in vitro and in vivo.
METHODS: After using the SA to expose HaCaT keratinocytes, we reevaluated the effect of the SA on cell viability, cell apoptosis, ROS, CAT, SOD, and other inflammatory variables in the heat-killed C.痤疮处理的HACAT细胞。接下来,为了诱导痤疮炎症的小鼠,ICR小鼠在右耳中注射了活内注射活的C.痤疮。然后检查了SA对这种炎症的影响。 Moreover, we explored the mechanism of SA on PPARγ/Nrf2 and NLRP3/caspase-1/IL-1βpathways by ELISA, immunofluorescence microscopy, and western blot assay.
RESULTS: Heat-killed C. acnes triggered remarkable cell apoptosis, ROS production,白介素(IL)-1β,IL-18,IL-6和TNF-αRelease,SOD和CAT活性降低,并上调了HACAT细胞中蛋白质的表达,包括上调IL-1β,PPARγ,PPARγ,NRF2,HO-1,NQO1,NLRP3和caspase-1,而SA通过部分损害PPARγ激活来抑制这些效果。此外,PPARγ的溶剂降低了痤疮梭菌诱导的IL-1β分泌和细胞内ROS的产生,从而下调了NRF2的表达。 Nrf2 activator (SFN) enhanced anti-inflammatory activity through antioxidant mechanisms, boosting intracellular ROS production, reducing SOD and CAT activity, and promoting the increase in ROS, HO-1, NQO1, and IL-1βlevels, while PPARγinhibitor (GW662) effectively inhibited this effect in heat-killed C. acnes-treated cells.最后,SA还表现出明显改善的耳朵发红,肿胀以及PPARγ,NLRP3和IL-1βIN体内的表达。
结论:>
