Abstract： 目的探讨白念珠菌胞壁溴化十六烷基三甲铵(CTAB)甘露聚糖影响脂多糖诱导人外周血单一核细胞(PBMC)产生的IL-6、IL-8的效应.方法3种浓度的CTAB甘露聚糖(1.00mg/mL、0.10mg/mL、0.01mg/mL)体外与人PBMC共孵育预刺激24h,然后加入脂多糖(50μg/mL)再孵育24h,收集上清液;在24h、48h时收集3种浓度CTAB甘露聚糖刺激组的上清液;阳性对照为脂多糖(50μg/mL),并设不加刺激剂的空白对照,酶联免疫法检测各组上清液中白介素-6、IL-8(IL-6、8)的含量.结果在24h、48h3种浓度CTAB甘露聚糖刺激组均未检出IL-6、IL-8;阳性对照脂多糖组IL-6含量为(478.507±24.876)ng/mL,IL-8含量为(529.655±53.279)ng/mL;阴性对照未检出IL-6、IL-8;1.00mg/mLCTAB甘露聚糖+脂多糖组IL-6含量为(85.620±16.058)ng/mL,IL-8为(123.940±20.319)ng/mL;0.10mg/mLCTAB甘露聚糖+脂多糖组IL-6含量为(210.086±27.874)ng/mL,IL-8为(206.798±31.878)ng/mL;0.01mg/mLCTAB甘露聚糖+脂多糖组IL-6含量为(201.387±32.396)ng/mL,IL-8为(203.133±36.012)ng/mL.结论白念珠菌胞壁CTAB甘露聚糖对脂多糖诱导人PBMC产生IL-6、IL-8具有下调作用.
